What about FFmpeg without any external libraries?

When ffmpeg (the application) crashes with a segmentation 
fault it is always the fault of the program and never the 
fault of the user. Additionally, all segmentation faults 
are important issues that we (really!) would like to 
know about.
To let us know, please test current FFmpeg (that you can 
find on the download page), provide the command line that 
allows to reproduce the segmentation fault together with 
the complete, uncut console output and ideally the sample 
needed to reproduce the crash.

The mentioned rules (gdb backtrace etc.) are valid on the 
bug tracher (you must only report a bug there if you want 
to provide all necessary information), it is not true for 
this mailing list.

Please understand (in case this isn't obvious) that such 
reports are basically the only thing we (the developers) 
request from users like you and it is also the only thing 
- together with samples - you (the users) can easily 
provide.

Thank you, Carl Eugen

Wouldn't this completely discard the goal of producing 
a "preservation copy"? Or do I simply misunderstand 
the term?

Greetings,

I've just started using ffmpeg - there are a lot of options. :)

I've read through a few of the encoding guides and have an initial
command line invocation that I'd like commentary on.

From:

http://www.webmproject.org/docs/encoder-parameters/#10-sample-command-lines

there is a recommendation for "best" quality.

I've based the following on it:

ffmpeg \
    -i INPUT.vob \
    -pass 1              \
    -passlogfile t       \
    -b:v 2M              \
    -auto-alt-ref 1      \
    -quality best        \
    -minrate 100K        \
    -maxrate 16M         \
    -lag-in-frames 16    \
    -keyint_min 0        \
    -g 360               \
    -skip_threshold 0    \
    -qmin 0              \
    -qmax 60             \
    -vcodec libvpx-vp9   \
    -strict experimental \
    -f webm              \
    -- - > /dev/null
ffmpeg \
    -i INPUT.vob \
    -pass 2              \
    -passlogfile t       \
    -b:v 2M              \
    -auto-alt-ref 1      \
    -quality best        \
    -minrate 100K        \
    -maxrate 16M         \
    -lag-in-frames 16    \
    -keyint_min 0        \
    -g 360               \
    -skip_threshold 0    \
    -qmin 0              \
    -qmax 60             \
    -vcodec libvpx-vp9   \
    -strict experimental \
    -acodec libvorbis    \
    -b:a 96k             \
    OUTPUT.webm

I'm looking for very good (or best) encoding. Encoding time isn't a
huge factor for me - at least right now.

Am I missing anything in the above?

Thanks for any hints!

It is definitely something to think of/consider. Thanks for the input.

Did you already encode anything with the vp9 
encoder? (Longer than a minute.)

I was following a video from a Google fellow:

Still encoding. :)

It takes a *long* time - something like 150x. I'll probably end up
changing to '-quality good'.

What I wanted to tell you is that I strongly 
suspect encoding time is always a very huge 
factor when using vp9, no matter what you 
thought before trying it.

Okay. Is there any explanation other than "it is not needed"?

Just out of curiosity, what is the effect of leaving it in?

Of course.

Longer command lines are harder to debug than 
shorter command lines (just as longer configure 
lines are harder to debug than shorter 
configure lines).

Some additional things to consider.

Perofrm some short tests, with a 1000 frames file, try with threads 1, threads 2, threads 3, etc 
Threads 1 gives you 100% of a single core say 4fps. Threads 2 doesn?t perform 8fps, because of overhead, and adding another thread adds less then the 2nd core. The sum of several single threaded encodings will result in more total-fps then 1 multithreaded encoding.

If you want 40fps you can easily add as many DualCelerons as mentioned before to get the desired result, you only need to add the ?missing? fps to the CPU you already have.

If you could send a 1000frames file, I?m happy to test te results for the mentioned Celeron.

Hi Carl, thanks for the reply.

1. I use libvpx to encode, and ffvp9 to decode.

--enable-libvpx --disable-decoder=libvpx_vp8 --disable-decoder=libvpx_vp9


2. Today I built the latest ffmpeg (2.4.1) with the old libvpx (1.3.0). It still generates vp9 files with incorrect PTS values at decode.


3. My preset file for encoding:
cat ~/.ffmpeg/libvpx-vp9-good.ffpreset 
vcodec=libvpx-vp9

g=120
lag-in-frames=16
deadline=good
cpu-used=0
vprofile=0
qmax=48
qmin=0
slices=4
b=2M

#ignored unless using -pass 2
maxrate=24M
minrate=100k
auto-alt-ref=1
arnr-maxframes=7
arnr-strength=5
arnr-type=centered

Sagara

What about FFmpeg without any external libraries?

Does that mean that you tested the issue now both 
with --disable-decoder=libvpx_vp9 and with 
--enable-libvpx --disable-decoder=vp9 --disable-parser=vp9 
or only with one decoder?

> 2. Today I built the latest ffmpeg (2.4.1)

2.4.1 is not latest FFmpeg.

All the while I was using only one decoder (vp9).

I only changed the libvpx from git version to the old libvpx v1.3.0 and rebuilt the ffmpeg, and re-encoded another vp9 file.

What other tests you think I should fro to narrow down the issue.

Hello.

I have some .TS video files which recorded from UDP. This files encoded by

ffmpeg -i "c:\somefile.ts"

this comment giving error message below

Could not find codec parameters for stream 0 (video

because of BISS key.

How can i define BISS Key to ffmpeg as parameter

Inadvance Thanks.

Message-ID: <205DBBE9F739414F9815C142C7EA61CC03612E0C@exchsvr01.torcrobotics.net>

Hello,

I am currently recording video of the desktop using UScreenCapture set up as shown in http://nerdlogger.com/2011/11/03/stream-your-windows-desktop-using-ffmpeg/, that's all set up working fine. Running the ffmpeg static 64 bit build from 2014-09-28 (git-3edb9aa) in Windows 7 64bit

I get playable fragmented mp4 (played in VLC) saving correctly with the following command:

ffmpeg -f dshow -i video="UScreenCapture" -vcodec libx264 -r 25 -q 5 -preset ultrafast -movflags frag_keyframe  C:\Users\user\Desktop\video.mp4 -y

I'd like to segment files by time, so I get X minute chunks of video that are all individually playable as well as preserving fragmentation in case of power loss (this will be running on a portable computer).

When I run:

ffmpeg -f dshow -i video="UScreenCapture"  -codec copy -map 0 -f segment -vcodec libx264 -q 5 -r 25 -preset ultrafast -movflags frag_keyframe -segment_time 10 -reset_timestamps 1 C:\Users\user\Desktop\Video_%04d.mp4 -y

I cannot get the last file (the fragmented one) to play at all. (The segmented files before the last one are fine) The last file has data in it (filesize is non-zero) but VLC cannot open it. Ideally the fragmented file wouldn't require any additional processing later to turn it into a non-fragmented file that's playable.

Any help would be appreciated.

Thanks,
Mark

"The sum of several single threaded encodings will result in more total-fps
then 1 multithreaded encoding."
This is interesting.  So whatever route I take (many separate boxes or one
many core system) feeding it with several jobs at once and limiting it to
one core is the way to go.
The issue with what your suggesting then is that if there is only one or
two jobs to run, a lot of the boxes are going to be sitting there doing
nothing.  Maximizing the throughput on your system requires it always being
feed the maximum # of jobs.   The dual Xeon (or lesser but still many core)
is going to be more flexible in that regard (so the high price tag is for
that flexibility).

Thank you Carl, i've tried with my sample and the
current Zeranoe FFmpeg build (git-c29d999 64-bit)
but no luck. Is it already in the win builds?
Or can you provide me a command line that worked?

Thanks,

With some clever thinking you can divide your source-file in  amount of pieces = # cores-1. This way all cores create 1 audio and # cores -1 video parts with can be catted together and muxed to 1 new file. Catting and muxing doesn?t cost any time in relation to the time needed for encoding. Your source file ProResHQ is afaik already a I-frames only file so dividing by # cores -1 is very easy.

Yes if the one time investment in thinking is more costly.

Subject: [FFmpeg-user] Can ffmpeg replay a live stream of constantly growing
	segmented *flv files?
Message-ID: <CAJB=bRaWoviQuqu262Qny5g1YXYUjVfTCAEgjoDhUGy4VS0oZw@mail.gmail.com>

Hi all,

ffmpeg question:

I have configured nginx to segment a live stream
from a camera into sequential *flv files (about 1 minute duration each)
 in a directory. Each *flv file has a timestamp. For example:

[me at mybox /mydir] ls -lr test1*flv
-rwxr-xr-x    1 root     root      9898994 Sep 17 20:10
test1-1410946937.flv*
-rwxr-xr-x    1 root     root     10450933 Sep 17 17:42
test1-1410946906.flv*
-rwxr-xr-x    1 root     root     10437684 Sep 17 17:41
test1-1410946875.flv*
-rwxr-xr-x    1 root     root     10441149 Sep 17 17:41
test1-1410946844.flv*
-rwxr-xr-x    1 root     root     10454367 Sep 17 17:40
test1-1410946813.flv*
-rwxr-xr-x    1 root     root     10114779 Sep 17 17:40
test1-1410946783.flv*
-rwxr-xr-x    1 root     root     10454252 Sep 17 17:39
test1-1410946752.flv*
-rwxr-xr-x    1 root     root     10449784 Sep 17 17:39
test1-1410946721.flv*
....
<more get constantly added>

My question is:

I would like for a way to create an rtmp live stream that are the contents
of the *flv
files in this directory combined
- keeping in mind new files may be added as this is a live stream.

Is there a way to get ffmpeg to do something like this?

I thought perhaps the concat protocol could be used for this, but I *think*
that is a one time read on all the *flv files and no way for it to discover
the newly generated files in that directory.

Thanks for an ideas.

My fault, the current git head is not yet in the
Zeranoe windows builds. I'll wait and post the results.

Even though ffmpeg's configure script does not report any error, I have no idea for this kind of error in make phase.  Please help me!!

My configure option is:
$ ./configure --prefix=/Volumes/ffmpeg_compile" --pkg-config-flags=--static --enable-libilbc

NOTE:
I know libilbc have updated on September 18th.  With this update, libilbc can not be built with cmake.  So I build it with the following procedure:

$ cd libilbc
$ libtoolize
$ aclocal -I m4
$ autoheader
$ automake -a -c
$ autoconf
Note that I build each auto tools with "./configure --prefix=/Volumes/ffmpeg_compile" option.

$ ./configure --prefix=/Volumes/ffmpeg_compile --disable-shared
$ make
$ make install

The cause of this error seems in libilbc, not ffmpeg.  I found old version of libilbc and it does not cause error while making ffmpeg.  

I'm sorry for all the fuss...

As I wrote in an earlier thread I am using ffmpeg to mix three audio streams down to a single 5.1 stream, using this syntax:
?
ffmpeg -i "original program filename.ts" -c:v copy -filter_complex '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1:FL=c0:FR=c1:FC=c2:LFE=c3:BL=c4:BR=c5' -c:a mp2 "converted program filename.ts"
?
This works fine on my OS X machine, which is running this version:
?

BUT if I try to do the conversion on a Debian Wheezy box, the converted file doesn't play well on low-powered machines, even though I use the exact same options.  The version there is from the
deb http://www.deb-multimedia.org wheezy main non-free
source (at http://www.deb-multimedia.org/), and has a much lower version number even though it was apparently built later:

What is the difference between the two versions that might cause one to produce jerky video and the other smooth playback, and is there any way I can get something more like the OS X version on my Debian box?

This is old and not really supported on this mailing list.

I have no idea why you are trying this version that is 
exactly two years old (well, I do know now that I looked 
at the new download page, it actually is highly 
misleading, sorry about that).

Please either compile current FFmpeg git head by 
yourself, by default you get a static binary that you 
don't have to install to use and that cannot interfere 
with anything you already have on your system.

As an alternative, please use the static binaries 
provided on http://johnvansickle.com/ffmpeg/

One is a little too old and unsupported the other

Then please also test with 
--enable-libvpx --disable-decoder=vp9 --disable-parser=vp9
(If disabling the parser works at all, I don't know.)

That's it, I just went to the download page at ffmpeg.org (http://ffmpeg.org/download.html[http://ffmpeg.org/download.html]) and clicked on Linux Packages and it took me to http://ffmpeg.org/download.html#build-linux[http://ffmpeg.org/download.html#build-linux] and there I clicked on "Stable", which took me to http://www.deb-multimedia.org/[http://www.deb-multimedia.org/] and there it says:

For wheezy (stable) amd64, armel, armhf, i386, ia64, kfreebsd-amd64, kfreebsd-i386, mips, mipsel, powerpc and sparc packages

non-free is for i386 and amd64 arches only.

or

or

I just picked the first one and added it as instructed and then used apt-get to install that version. Should I now use apt-get remove to uninstall it and then remove that entry from my /etc/apt/sources.list ?

That's a bit beyond my level of understanding, though if there were clear step-by-step instructions on how to do that (that don't assume any prior knowledge on my part, especially with regard to git) I might have tried that. However...

I tried that one and it seems to work fine. And I REALLY wish that had been offered on the download page. The reason is that in my attempts to install ffmpeg, first from the Debian repository (which actually brought in the libav version, I believe), and then from the download link mentioned above, a whole lot of dependencies were added that I would rather not have seen added. Perhaps they don't do anything bad other than occupy disk space but still, if they don't need to be there I'd rather they weren't. And apt-get is really good about bringing in dependencies when you install software, but when you go to remove it, it generally only removes the specific package that you've asked it to. So I REALLY wish that the download page had at least mentioned this option.

Seems strange to me that the "ancient" version seems to work better than the "little too old" version in this particular application, but maybe it has something to do with the different underlying OS. In any event I have no idea how you'd get a newer version for OS X, even if that were important to me, which right now it isn't.

Believe me, at first I was plenty confused by all this business surrounding the different versions of ffmpeg. I have no idea why the Ubuntu/Debian folks thought it was okay to just replace ffmpeg with libav/avconf, especially if they were not going to make sure it was backward compatible. But, that is a fight I don't want to get into the middle of. It makes it hard for us users though, especially because up until a week or so ago I had never done anything with ffmpeg directly, therefore I had no idea there were different versions and forks and all that.

> Please find more information on

I saw that page sometime in the last two or three days and then it clicked. Still, until you mentioned that stable version, I hadn't found anything that ran under Debian and produced videos that were watchable on a low-powered HTPC.

I don't know who is in charge of maintaining that download page at http://www.deb-multimedia.org/[http://www.deb-multimedia.org/] but my suggestion would be that newer builds be linked from that page, or that alternately, the ffmpeg.org download page offers a link to the http://johnvansickle.com/ffmpeg/[http://johnvansickle.com/ffmpeg/] page as a _first_ choice. Because, I suspect that is the version that most Ubuntu and Debian users (that know enough to seek out ffmpeg rather than fiddling around with the libav version from their repositories) would actually want.

Anyway, thank you very much for bringing that version to my attention; that seems to be the one that works!

I do have another question: When I am running ffmpeg this way, it prints out the following four lines as part of its output - I notice them because they are all or part in green and yellow text:

[Parsed_pan_1 @ 0x3bd7e20] This syntax is deprecated. Use '|' to separate the list items.
[Parsed_amerge_0 @ 0x3bc73c0] No channel layout for input 1
[Parsed_amerge_0 @ 0x3bc73c0] Input channel layouts overlap: output layout will be determined by the number of distinct input channels
[Parsed_pan_1 @ 0x3bd7e20] Pure channel mapping detected: 0 1 2 3 4 5

I don't understand all that but it's the first line that has me concerned. What does it mean by, "This syntax is deprecated. Use '|' to separate the list items"? And is there anything else there I should be concerned about? For reference, I'll repeat how I am invoking ffmpeg:

ffmpeg -i "original program filename.ts" -c:v copy -filter_complex '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1:FL=c0:FR=c1:FC=c2:LFE=c3:BL=c4:BR=c5' -c:a mp2 "converted program filename.ts"
?

That should have read "static version", not "stable version."

In any event I have no idea how you'd get a newer version for OS X, even if that were important to me, which right now it isn't.

Actually, I got to thinking about it and put two and two together and realized that I must have downloaded that version back in May. from this page:  http://www.evermeet.cx/ffmpeg/

Which is the page linked to from the ffmpeg.org site if you specify that you want "Static builds for OS X Intel 64-bit"

So I grabbed a the newest static build from there and installed it, just to keep current.

But my (rhetorical) question is, if the download page can link to the static builds for OS X, why doesn't it do that for Linux?  It would be a big help if it did!

first:
there exists no offical ffmpeg binary, for no OS at all
whatever you find linked for binarys is just a pointer

second:
because on Linux you typically get packages from distribution
or 3rd party repos or fire up a compiler / rpmbuild

third:
in case of Apple 98% of OSX users have zero technical knowledge
and *rely* on a random binary found somewhere

but as said - there is *no official binary* at all and whenever
you use one from a random source instead self built or from
your distribution you do that at your own risk

there is a *large* difference between using a distributions
repo with signed packages or click for every app you want
to use on a different random website clueless about who
built the binary

if you don't realize that - well, security is not your job

and if it only is because *if* there was a intrusion in
a large linux distributions infrastructure you likely
read about in some news - if the same happened on a
random domain you never will hear about and the same
likely happens if the ffmpeg server was hacked since
it is a widely known project and not just one website
out of millions

Yet in the case of OS X, the link is from the ffmpeg.org download page. To the casual user, that sure looks like it's been given an "official" stamp of approval.

It was getting the package from the "official" repo that caused me to get the libav version. It was using the third party repo that caused me to get an old version.

> third:

And why would you assume that Linux users, particularly Ubuntu users, are any different? It might have been true ten years ago that almost all Linux users had a great deal of technical knowledge but since Ubuntu came along, anybody and their grandmother can use Linux, and never have to touch a command line if they don't want to.

In my case, it's the whole thing about "git" that first mystifies me, and then the process of compiling from source. I know there are Linux users that do that, but I can only do it if there are very clear, explicit, line by line instructions that don't assume any prior knowledge on my part. Otherwise it's like handing me eggs, flour, and sugar and saying "bake a cake" - I would have no idea where to begin and the results are probably going to be a hot mess.

> but as said - there is *no official binary* at all and whenever

Then in theory, the ffmpeg.org download page should not link to any of those at all, or at least should include a big disclaimer to that effect. But then again, any software you download is risky if you don't personally know the developers. If these are static builds that have worked for others and haven't caused anyone problems, I don't see any harm in making it easier for people to have access to such builds. And I definitely don't see why there should be a different standard for OS X users and Linux users. Not all OS X users have zero technical knowledge (I'm pretty sure the percentage is less than 99%!) and not all Linux users started coding at the age of 12. Each group has users at all levels, even if the Linux user base does tend to skew toward the more technically inclined.

I stumbled across that as well. For all I can tell, the filter syntax
for a list of parameters to a filter argument was changed and the
documentation for the pan filter never updated. Apparently, the eight
filters named in the source below require you to use '|' instead of
':'.

libavfilter/avfilter.c:
#if FF_API_OLD_FILTER_OPTS
            if (   !strcmp(filter->filter->name, "format")     ||
                   !strcmp(filter->filter->name, "noformat")   ||
                   !strcmp(filter->filter->name, "frei0r")     ||
                   !strcmp(filter->filter->name, "frei0r_src") ||
                   !strcmp(filter->filter->name, "ocv")        ||
                   !strcmp(filter->filter->name, "pan")        ||
                   !strcmp(filter->filter->name, "pp")         ||
                   !strcmp(filter->filter->name, "aevalsrc")) {
            /* a hack for compatibility with the old syntax
             * replace colons with |s */

I believe your filter should be as such:

'[0:1][0:2][0:3]amerge=inputs=3,pan=5.1:FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5'

because the first parameter is l=5.1, the second
outdef=FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5, and the ':' separates
parameters.

Just guessing,
I might submit a patch,
Moritz

the "casual user" would also not read any disclaimer or what not

don't get me wrong but a Ubuntu user is not a Linux user for me by

only because you refuse to learn

i stared at the same point in 2006 and now maintain production servers

If these are static builds that have worked for others and haven't caused anyone problems, I don't see any harm in making it easier for people to have access to such builds. And I definitely don't see why there should be a different standard for OS X users and Linux users. Not all OS X users have zero technical knowledge (I'm pretty sure the percentage is less than 99%!) and not all Linux users started coding at the age of 12. Each group has users at all levels, even if the Linux user base does tend to skew toward the more technically inclined

that may all be true but don't change the fact ffpeg is source only and 
even if it is not for legal reasons because multimedia codecs are deep 
in patent issues, so you are allowed to write code and publish it but if 
it comes to binaries depending on where you live and how well known you 
are you end with one foot in the jail

Well let me put it this way - suppose I told you that before you were allowed to drive a car, you had to know how to tear down and rebuild an engine.  While that might be a useful skill, not everyone who drives a car wants to know anything about that.  But if you had that skill, perhaps you might be condescending toward mere drivers, just as you have been to me in your insulting reply.

I came to this list looking for help in USING ffmpeg, not in BUILDING ffmpeg.  I was under the impression that this list was for ffmpeg USERS, not developers.  Compiling software is something I have only had to do a handful of times in my life, and every time I have had to do it, the creators have been kind enough to provide explicit instructions of the type I mentioned in my previous message.  I have no desire to write or compile software generally, and at my age (I am in my 60's) it is difficult to pick up new skills.  I don't even feel entirely comfortable using the command line because I am always afraid I will break something, and I have done that before.  And even if I did figure out how to do it once, it would not be a skill I would retain, because I might not need to do it again for a few years, or maybe ever.

Good for you.  You learned this stuff because it was useful to you in life and for your employment.  I doubt you would have put anywhere near that level of dedication into it if you had thought that it was something you might never need to know how to do again, unless you are just generally attracted to that sort of knowledge.  We all have our areas of interest, and building software isn't one of mine, any more than getting under the hood of a car and fixing a motor.

I don't know if you are a developer of this project or just a user or somewhere in between, but I certainly hope your views don't represent those of the ffmpeg development team.

Anyway can we please just drop the insults?

(And if by some chance this post gets me banned from the mailing list, I just want to say thank you to all who have helped me, it was much appreciated!)

I don't think either situation really guarantees anything, does it?
I'm not in a position to check every line of code in a piece of software before I build it.

I can assure you that following these instructions it is quite simple to compile a recent version of FFmpeg, even without experience (it was my case):

Thank you.  I tried this:

ffmpeg -i "original program filename.ts" -c:v copy -filter_complex '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1:FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5' -c:a mp2 "converted program filename.ts"

and while that worked, I still got the warning message.  Then I tried this:

ffmpeg -i "original program filename.ts" -c:v copy -filter_complex '[0|1][0|2][0|3]amerge=inputs=3,pan=5.1:FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5' -c:a mp2 "converted program filename.ts"

And got this:

And it did NOT do the conversion, so it was not complaining about the 0:1, 0:2, 0:3 syntax.  So then I tried:

ffmpeg -i "original program filename.ts" -c:v copy -filter_complex '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1|FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5' -c:a mp2 "converted program filename.ts"

And then I got:

[Parsed_pan_1 @ 0x3afde20] Pure channel mapping detected: 0 1 2 3 4 5

But, no complaints about the deprecated syntax!  So it appears that it does want the | rather than the : after the 5.1 as well.

Thanks much!

there was no insulting intention

if someone needs a binary he can use it
if it is not available - well, build at your own or hire somebody

that is not insulting - that is the thruth

that i later switched to IT as daily job was nothing but play around and

you stopped to read the lines after your quote
your mistake!

a signed package is different from random crap and the difference starts 
by click on the download link - you are sure the DNS you are using is 
trustable? in case of a signed package even if it is compromised by a 
MITM the package manager would refuse to install / update the package 
until the MITM was able to steal the signing key of the distribution you 
are using

> I'm not in a position to check every line of code in a piece of software before I build it

me too - but i somehow trust well known upstream developers which is not
the case for random binarys where nobody knows if the unmodified 
upstream source was used

in case of distribution repos you know at least that they are signed and 
changes/updates *likely* reviewed or if something bad happend some news 
will tell about

in case of a hacked random server you used to download you know nothing 
nor will any press take notice in case of a intrusion - if that happens 
for opensource projects with some reputation you will hear baout

Except that it leaves out the third, most reasonable option - use the static build that someone else has already made the effort to create.

Maybe YOU would not do that, for whatever reasons.  That's certainly your prerogative.  My original point was that I don't see why anyone thinks that it's perfectly fine to give OS X users a static build, but hide it from the Linux users until someone is kind enough to mention it in a forum such as this one.  Either all the static builds should be linked from the download page, or none of them should.  I would definitely prefer the former, because it makes it a lot easier on users who don't have your level of technical savvy.

Just because I can see what I typed doesn't mean I can fix it.  Case in point, when I installed ffmpeg (or libav masquerading as ffmpeg) from the Debian repository, it brought in a whole bunch of useless dependencies that I now realize I don't need.  But removing that version of ffmpeg didn't get rid of them, so now I am stuck with them.

I can't think of any instance where that has actually happened to me unless I stupidly clicked the wrong button.

So why are you so interested in keeping the static builds hidden from Linux users?

Now you are putting words in my mouth, figuratively speaking.  I would have NEVER used the word "binary" in that way.  In fact I would not have known to ask for a static build prior to this thread.

Anyway, if the project doesn't offer it then what exactly is being offered to OS X users?

> * the answer is: whereever someone has taken the source, built one
offered the result for others

And when someone does that, IMHO it ought to be linked to from the download page, unless there is some compelling reason not to.

> no need to consider get banned by speaking frank - hopefully.

You would be surprised what little bit of disagreement it takes to get you banned in some forums.

no you are not and honestly wonder that Debian/Ubuntu don't remove them 
since it is a repeated flame against RPM based distribution that they 
don't (which is not true, yum do for a long time if configured correctly 
as well as "package-cleanup --leaves" lists all packages which can be 
removed because nothing else depends on them and after remove the first 
one it offers other "freed" packages)

put "clean_requirements_on_remove=1" in /etc/yum.conf on 
RHEL/CentOS/Fedora as exmaple is the key that if you install package a) 
which pulls in b, c, d, e, f and 1 hour later you decide to remove a) 
the others are automatically selected to be removed until no other 
package you installed in the meantime requires them

That would be true except for this:

"Compilation & Installation

You can compile ffmpeg to your liking. If you do not require certain encoders you may skip the relevant section and then remove the appropriate ./configure option in FFmpeg. For example, if libopus is not needed, then skip that section and then remove --enable-libopus from the Install FFmpeg section."

Now if only they would follow that up by saying, "If you don't know which encoders you need or how to use the configuration options, here is how to build a 'standard' version of ffmpeg...", then this page might actually be useful.  The problem is that when you offer a lot of options, people such as myself that have no clue what those options do get lost really fast.  All I want and need is a standard version that will work.

However, if someone has any idea of what they actually want and need, that seems like a pretty thorough guide.

Basically, however, the question that I think needs to be asked is this:

If I go to the download page and it sends me to http://www.deb-multimedia.org/ and I add the repository suggested (deb http://www.deb-multimedia.org wheezy main non-free) to my /etc/apt/sources.list, why is it supplying an old version?

This, I think, is the crux of the matter.  Had I received a current version from that source, we would have not had any of this discussion.

define "standard"

* all supported codecs
* minimized supported codecs
* if minimized which ones

> However, if someone has any idea of what they actually want and need, that seems like a pretty thorough guide

you need an idea otherwise you end what about you caomplained before 
"the package i installed pulled a ton of dependencies" - so in other 
words "default" would support only limited codecs or pull a lot of 
dependencies with their cahin-deps

there is not much between and no matter what you do the next day 
somebody would complain why all that deps are required or a static 
binary is 100 MB large or why the codec he needs right now is not supported

that answer is *really* easy - because who ever did built that binary 
don't care or has no time - if you want soemthing else you need to do 
that at your own - that's the benefit of open source: you can do so, in 
case of closed source all that questions would not exist

Another thing you may want to keep in mind is that many would consider a
"standard" version of FFmpeg of little use out of the box. The reason for
this is the FFmpeg source code does not include popular encoders like x264
and FAAC (i.e. h.264 video encoding and AAC audio encoding). In order to
use these, you must download their sources, compile them first and then
compile FFmpeg after you've configured it to look for the appropriate
libraries (libx264 and libfaac, for example). Sometimes, but not always,
these libraries are installed on your system so you can have FFmpeg
dynamically link to them. However, for my own use, I always statically link
the ffmpeg executable so I can move it from machine to machine without
having to worry about what libraries are installed on each system. I do
this with Mac OS X, but the same idea applies to Linux.

It would be nice to have one place where a Mac, Linux and Windows binary
can be downloaded, but because of licensing and the need to use code from
separate projects, this gets complicated. :-(

About compiling: just try with the options enabled there, why bother
for the moment?

About deb-multimedia: they have now even a wheezy-backports repository,
and there you can get a more recent version. Have a look:

You aren't alone. I've mentioned this problem, on this list, many times. Most open source software uses a combination of commandline tools, with scripts and code in various formats and languages required to build it. This is emphatically not simple - at least not as simple as loading a Visual Studio project in Windows. It is not reasonable to expect everyone to be able to do it.

The open source community deals with this situation by denying that it exists and is often inexcusably impolite:
> only because you refuse to learn
...like that. There is often a complete lack of respect for any form of skill or ability other than software engineering, to the point that some projects (ffmpeg included) have suffered some quite egregious technical omissions because they simply won't take anyone's input.

Don't feel bad. The technical problems we're discussing here, and the attitude problem underlying them, are one of the main things holding back open source software from what could be its full potential.

then just use a source for a binary like a distribution

> The open source community deals with this situation by denying that it exists and is often inexcusably impolite

it does not exist - the developers offer *their work* in form of
source code - who do you think you are to demand them offer a
"just happy to use" binary additional to the development work?

you still don't get it

* just intsall the packge from your distribution
* if it don't fullfill your needs complain there
* if you don't want to complain there just learn to build the source

> Don't feel bad. The technical problems we're discussing here, and the attitude problem underlying them, are one of the main things holding back open source software from what could be its full potential

it has the full potential

* just use pre-built packages from the sources
* hire one to build them for your needs
* learn to build them at your own

well, finally you could offer enough money to a upstream
developer for build a binary at your your needs

try the same with closed source and look how far you get

"Software engineering"? I repeat: I compiled FFpmeg following the
instructions on the site and that was the very first time I compiled
anything. It worked at the first try, on an eeePC with an Atom N450.

don't waste your time - Phil is known for comlain against ffmpeg
and if he would have used all the time to write complaints for just 
learn how to deal with build it he could offer pre-compiled binaries for 
every OS out there

P.S.: i am known for not be nice always but at least i do my homework

Good point. Except that I use a lot of self-built libs (ahead of
rpmfusion) in the process as well. Has libfdk_aac finally been
packaged? I recall a package review which was never completed - I could
use that. I would also need to contemplate a proper versioning scheme
for snapshots.

I might even avoid this and risk allowing to have two binaries of the
same name lying around. ;-)

Carl Eugen would question this, wouldn't he? ;-)

Thanks for the inspiration,

You created this problem.
If you want less hassle from users, make the software easier to use. If you can't be bothered, deal with the fallout.
Either way, you are not the boss, you are not in a position of authority, and it is not your place to tell peopl eoff.

i don't bother about libfdk_aac

with "-acodec aac -strict experimental" you can use the builtin AAC 
encoder which works just fine for at least 2 years here and don't pull 
any deps

the opposite is true, it replaces the meta-package, installs the binary 
to /usr/local/bin as well as the symlink in /usr/bin and replaces the 
executable binaries from rpmfusion (in other words a drop-in 
replacement) while ffmpeg-libs for deps is still installed and untouched 
from rpmfusion

works fine for years now using the latest ffmpeg and any other package 
built against the rpmfusion libraries works untouched as before

No, you're the one throwing insults around on a mailing list. Examine your own behaviour.
If you don't like the fact that people find compiling ffmpeg difficult, make ffmpeg easier to compile.
If you don't want to do that, that's absolutely fine, you aren't required to - but you may not reasonably tell other people off for complaining. Their complaints are justified.

Stop bullying other users here, this is not acceptable!

FFmpeg compiles on many common and a few very unusual 
systems with "./configure && make" if you have a 
compiler installed, I don't think you can make 
compilation significantly easier.

If compilation does not succeed on any platform, 
please tell us!

And please stop trolling here, it is not welcome!

my behaviour is fine - honestly you have no clue how
it sounds if i forget about it!

why should i?
as said i am a user and managed to build from the sources

nobody is forced to do so - everybody can use distribution
packages *but* complain why they are not recent enough
won't work - pay the distributions package mainatiner,
wait until he updates them, update your distribution version to get 
newer package or just RTFM and build it at your own

all valid options exists

> If you don't want to do that, that's absolutely fine, you aren't required to

fine

> but you may not reasonably tell other people off for complaining

surely - the same way reasonable as you complain over years

> Their complaints are justified

no they are not, proven by the following output which did
take exatcly 20 seconds work and wait until the build is finished

Reindl Harald: And again, you come across as an insulting ass.  Look, nobody forces the developers to offer anything.

Thank you, Phil.  I almost said something earlier when I thought maybe he was a developer (because I did not think that just another user would have the unmitigated gall to talk this way) that if this was how the developers acted toward people, I could fully understand why the project was forked.  But I thought I had better ask if he were a developer first, and I am glad I did! Now that I know he's only a user I think he has a hell of a lot of nerve to talk to anyone the way he's been carrying on today (not that I would think any more highly of such conduct if he were a developer, but at least a developer would have more status to talk that way).

I am done with this.  The truth is that as long as the static builds are available, that is all I want or need.  I did learn a few things from some of the participants and I do appreciate the help, but I am not real likely to ever try to build ffmpeg.  For one thing I have absolutely zero desire to do that, and for another thing, it seems to me like the current version ought to be offered in the repositories (and clearly marked as such, not obfuscated among a whole bunch of choices that would leave anyone bewildered as to which to pick), and hopefully someday that will be the case.  However, I have no desire to continue this thread, since it has become extremely counter-productive.

Phil tries to do for many years here

> But when you put software out into the world, whether it is free or something you have to buy, and whether it is for Linux, OS X, or Windows, people are going to give their opinion and say what they do and don't like about it.

and other people are going to give their opinion like i did - so what

you just could have aid "thank you for now knowing that" after i 
explained you that upstream just offers source code and nothing else, 
well i even explained you the legal side why this can't change

complain at the institutions responsible for patents

if somebody builds a static binary of ffmpeg with x264 then it is his 
choice and risk - doing that in the wrong country or piss up the wrong 
people holding patent rights may bring him straigt to jail

> If getting a current version is harder than with other similar software

other free software in Linux distributions is built the same way as 
ffmpeg and if they are renect just say thank you to the package maintainer

> people have a right to note that and say they wish it were different.

you still don't get it - if the version your distribution offers is not 
recent enough *complain there* because it's the apckage maintainers 
fault not to keep on track and nobodys else

he did build the package within the repos from the upstream sources and 
he is repsonsible to update them - nobody else - if you want rececnt 
binaries complain there or just build them at your own

Thank you! For some reason, when I saw the word "backports" I thought they were talking about older versions.  Don't know why, I just did.  Now that I know better, I'll keep it in mind if I ever have the need to seek out a newer version.

http://en.wikipedia.org/wiki/Backporting

backport means "we took functionality from later distribution releases 
to a older one" in general - specifically backport in context of 
software means "we found a bug in the recent version, it turned out that 
it existed for years and we backported the fix to older releases too so 
that you don't need to force a major update"

Subject: [FFmpeg-user] Problem with GDIGRAB device on Windows 7
Message-ID: <54320BF2.4030302@xopnetworks.com>

Hello ffmpeg/gdigrab gurus!

We are using "gdigrab" device on Windows to share/stream video for a 
specific application window (identified by a title as "gdigrab" requires).
Everything works great on Window 8.x - actual application window (and 
not the region on the desktop occupied by the application window)
is getting shared and successfully played by the player on the receiving 
side. Which means that even if shared window is overlapped by the
other window on the source - still the application window is getting played.
Unfortunately, as we discovered, "gdigrab" doesn't work correctly on 
Window 7. And instead window sharing it actually does the region sharing.
Which pretty much means that if shared window is being overlapped by the 
other window on the desktop - that's what getting played on the
receiving side.
Just for reference - we tried to do window sharing with 
screen-capture-recorder and unfortunately got exactly the same results.

I would greatly appreciate any help/advise anybody can provide on the 
subject. And please let me know if there is any other information I can
provide.

Greatly appreciate your help
Yan

Hi,

Asf video streaming is working smoothly at my end  but Now I want to do HLS by using ffmpeg, ffserver and (VLC or iPAD) as per below order.

Step 1) execute vlc
Step 2) execute ffserver
Step 3) execute ffmpeg

I tried a lot but not getting any ffserver config file that can be used for HLS streaming . 

Please share working ffserver config file with me.

>(hue, lut, geq and mp=eq2 come to mind.)

I've tried the following commands, but none worked to brighten a dark
video:

I tried each of those commands, but observed no change:
-vf mp=eq2=1:1.68:0.3:1.25:1:0.96:1 
-vf "lutyuv=y=val*1.3"
-vf "lutyuv=y=val*2.0"
-filter:v lutyuv="y=gammaval(0.7)"

Here's how I used the command, where HERE contained one of the
switches above

ffmpeg -ss 00:05:00 -t 20 -i input.mp4 HERE -vf scale=640:-1 -c:v
libx264 -pix_fmt yuv420p -c:a copy -shortest -f mp4 output.mp4

Thank you.

I know there are Linux users that do that, but I can only do it if there are very clear, explicit, line by line instructions that don't assume any prior knowledge on my part. Otherwise it's like handing me eggs, flour, and sugar and saying "bake a cake" - I would have no idea where to begin and the results are probably going to be a hot mess.

To use your cake analogy, there are very many ways to end up with a cake.

You can go to the store and buy one (Quicktime Pro). The cake should
be just how you like it, and you can ask people to make it just how
you like it before you buy it.

You can go to the store and buy cake mix (Handbrake). This is cheaper,
but you need to do some of the mixing and baking yourself.

Alternatively, you can go get eggs, flour and sugar and mix it and
bake it yourself (ffmpeg). This is the option you have chosen. If you
don't like the steps involved, go to the store instead.

ffmpeg is open source software delivered as source code. If you have
complaints about how binaries of it are packaged, you are complaining
in the wrong place - talk to the packager.
If you have complaints about having to compile it to get a supported
version, you're complaining in the wrong case - no-one here cares, it
is part of the cost of using ffmpeg that we all (well, apart from
Phil) agree to.

Cheers

Please never post command lines that contain variables, 
always post actual command lines that you tested 
including their complete, uncut console output.

As far as I am concerned, using -vf filter1 -vf filter2 
is either undefined behaviour or not supported, the 
filter option does support multiple filters.

What on earth are you beating this dead horse for?  You're taking the entire analogy to the ridiculous.

As a user of the software - remember, this was supposed to be a list for ffmpeg USERS, though I am starting to think that is false advertising - all I was wanting to know is how to get a newer version.  Someone told me about a precompiled static version.  It works.  I will use it.  I didn't have to buy it.  Problem solved.

And you are being utterly ridiculous beyond belief when you suggest I talk to the packager.  For one thing, as long as I have the static version, I couldn't care less what the packager does.  For another thing, as a user, I have no idea who the packager is.  And even if I did, they are probably worse Linux snobs than some of the people in this group seem to be, and I would get the same crap I am getting here, only worse, because after all, why should they listen to a mere user?  Never mind that they make their software for users, this attitude that many Linux developers seem to have is something you never see in the Windows world.  They make the software, and presumably want people to use it (otherwise they should keep it to themselves), but it's like they can't even take a constructive suggestion for improvement, let alone anything that might be construed as a criticism.  Or, they want you to file a bug report or feature request and then maybe five years later they will get around to actually acting on it, by which time I've usually moved on and found something better.

Phil and ME.  Don't forget me.  I am damn proud to be in Phil's camp in this case, and I had never heard of him prior to encountering this list.  Phil has his head screwed on straight, and you trolls that want to make a mountain out of a molehill really need to find a hobby or something.

I'm sure now you are going to try and convince me that using the static build is wrong somehow, and I'll tell you right now, I don't care.  It works, it solves my problem, and I am happy with it.  The only thing I am not happy about is some of you guys that just have to be so preachy even though none of you have identified yourself as a developer, and therefore you are attempting to speak with authority you don't have.

And anyway, I'm not complaining about having to compile it to get a supported version because I don't care if it's an unsupported version, as long as it will do the one thing I need it to do.  If I can find a version of ffmpeg that does that, I'll use it.  If I could have found a version of libav, or whatever that forked version is, that does what I want I would have happily used that.  I don't care about all this internal drama, I don't care about what is considered "correct" by you or anyone else, I don't care whether you or anyone else thinks I ought to learn how to do something that I have zero interest in, and frankly, if anyone feels I am wrong in thinking this way, I don't care what you think.  I don't care because you are also just mere users like me, and therefore anything you may have to say on the subject is your your own opinion, and I happen to think differently.  If I make a suggestion or a criticism, and you think I'm wrong, I don't care because you are not the person who would ultimately act on or reject it.

And if no one here cares, then why are there so many useless messages posted in this thread, that aren't helping anyone and that aren't going to change my mind in the slightest?  Are your lives so empty that posting crap like this is all you have to do?

Just stop.  Because you are typing to no one that cares!  And you could put your time to better use by actually helping people, instead of creating a pile of rotting, putrid horsemeat!

(No offense intended toward the people who actually did have helpful suggestions).

And now I am going to unsubscribe from this list, at least for a while, because I simply don't care to participate it this type of unproductive and unhelpful discussion, and I don't even want to read any more of this garbage.

This does display the video like I'd like it to look:
ffplay -i input.mp4 -vf "lutyuv=y=val*1.3"

Next, I tried combining the two "vf" commands, but it didn't work:

I suspect this should be:
-vf lutyuv=y=val*1.3,scale=640:-1

But I suggest you first try without scaling to 
find the right syntax to brighten your video.

Hi,

Asf video streaming is working smoothly at my end  but Now I want to do HLS by using ffmpeg, ffserver and (VLC or iPAD) as per below order.

Step 1) execute vlc
Step 2) execute ffserver
Step 3) execute ffmpeg

I tried a lot but not getting any ffserver config file that can be used for HLS streaming . 

Please share working ffserver config file with me.

Thanks
Ajay

Tried. No change.

I later managed to more narrow down the issue. Its the vp9 file itself having an issue. Many video packets having negative PTS values!

I presume the issue is libvpx-git is not ready yet. I'll check with webm project what options currently can be used. The libvpx 1.3.0 for vp9 is no use. Way too slow.

Here are some more insight.

The av_read_frame(pFormatCtx, &packet) returns PTS/DTS as follows. For negative PTS video packets I assigned the previous known PTS. Now the vp9 decoded frames comes with correct PTS values and player plays it very well.

Video PKT PTS: 0, DTS: 0, Size: 129
Video PKT PTS: 42, DTS: 42, Size: 31
Video PKT PTS: -9223372036854775808, DTS: -9223372036854775808, Size: 27
Negative video PTS: -9223372036854775808, DTS: -9223372036854775808 Last PTS assigned: 42
Video PKT PTS: 83, DTS: 83, Size: 25
Video PKT PTS: 125, DTS: 125, Size: 24
Video PKT PTS: 167, DTS: 167, Size: 23
Video PKT PTS: 209, DTS: 209, Size: 20
Video PKT PTS: 250, DTS: 250, Size: 20
Video PKT PTS: 292, DTS: 292, Size: 18
Video PKT PTS: 334, DTS: 334, Size: 18
Video PKT PTS: 375, DTS: 375, Size: 18
Video PKT PTS: 417, DTS: 417, Size: 19
Video PKT PTS: 459, DTS: 459, Size: 18
Video PKT PTS: 501, DTS: 501, Size: 18
Video PKT PTS: 542, DTS: 542, Size: 18
Video PKT PTS: 584, DTS: 584, Size: 18

Video PKT PTS: -9223372036854775808, DTS: -9223372036854775808, Size: 38
Negative video PTS: -9223372036854775808, DTS: -9223372036854775808 Last PTS assigned: 1084
Video PKT PTS: 1126, DTS: 1126, Size: 29
Video PKT PTS: 1168, DTS: 1168, Size: 26
Video PKT PTS: 1210, DTS: 1210, Size: 24
Video PKT PTS: 1251, DTS: 1251, Size: 22
Video PKT PTS: 1293, DTS: 1293, Size: 20
Video PKT PTS: 1335, DTS: 1335, Size: 19


I assigned last PTS directly to the packet as follows:
packet.pts = videoLastPTS;


The real issue is before the decoding, the av_read_frame() returns some video packets with negative PTS/DTS values.

1. Is it always correct to assign the last known PTS to the packet.pts but it works very well?
2. Is this issue known and already corrected in the git version of the ffmpeg? So that I can give it a try to the git version of the ffmpeg.

But as you can see from the message, something is wrong with the AC3
audio track (output stream #1:0). Have you tried stream-copying input
#0:0 or #0:1 instead of re-encoding it?

By the way, you have two outputs:
out%03d.ts (segment)
and
http://10.125.133.31:8080/feed1.ffm

and you are not specifying any parameters for the second one. Are you
sure this is what you are trying to achieve?

Yes. It actually generates the files as fast as it can (so I get a dozen files in a second or so) but if I don't kill the process nicely, the last generated file is not properly fragmented and is unplayable.

This is the atom structure from atomicparsley of the last file (broken), which has no moov or moof atom to define anything:

Atom ftyp @ 0 of size: 32, ends @ 32
Atom free @ 32 of size: 8, ends @ 40
Atom mdat @ 40 of size: 141345 (0*), ends @ 141385
                         (*)denotes length of atom goes to End-of-File
------------------------------------------------------
Total size: 141385 bytes; 2 atoms total. AtomicParsley version: 0.9.0 (utf16)
Media data: 141345 bytes; 40 bytes all other atoms (0.028% atom overhead).
Total free atom space: 8 bytes; 0.006% waste. Padding available: 0 bytes.

Actually, "#EXT-X-ENDLIST" is not added because you have specified 
"-segment_list_flags +live" in your ffmpeg command.
If you want to generate a live HLS stream, use +live flag and the tag 
will not be added (like in your example), if you want to generate a VOD 
stream, remove the flag and the tag will be added.

However this won't fix the issue you are reporting that "out005.ts" 
isn't added to the playlist and I can't help you with that, sorry.
Just wondering: are you sure that out005.ts contains useful data?

************************************************************************************
Yes i am sure out005.ts contains valid data as i can play this out005.ts in VLC player smoothly.
when i manually add this segment to playlist file then also it plays as part of playlist file.
I want to know why this segment out005.ts is not adding to playlist file ? 
Is it known issue ? or i need to provide some other options to command line.

below is the command that currently i am using
ffmpeg -i 'udp://226.0.0.1:1234?fifo_size=50000&overrun_nonfatal=1' 
-map 0:v:1 -map 0:a:0 -vcodec libx264 -acodec copy -f ssegment

Subject: [FFmpeg-user] Getting http_code on avformat_open_input() error
Message-ID: <CAK_w-=5xX3zHcE4Z=7-SBvYHiXg_hcsC9vfYYU2A=VqL+Krhfw@mail.gmail.com>

Hi,

    I'm using RTSP over HTTP from ffmpeg and want to get an extended error
when avformat_open_input failed, e.g. Unauthorised error occurred
 ./ffplay "rtsp://username:incorrectpassword at 192.168.0.3:80/my.sdp"
-rtsp_transport http -loglevel debug -stats

  In the ffmpeg log I have
  http_code=-1807328772
  HTTP error -1807328772 HTTP/1.1 401 Unauthorized

   However I can not get this status 401 via avformat_open_input.

    int errCode = 0;
    if ((errCode = avformat_open_input(&formatContext, c_url, NULL,
/*NULL*/&options))
!= 0) {
      // Print error description
      char errbuf[128];
      av_strerror(errCode, errbuf, sizeof(errbuf));
      E("avformat_open_input() failed with code %d (%s)", errCode, errbuf);
      // Cleanup
      // ...
    }

   The error that I have is
   avformat_open_input() failed with code -5 (I/O error)


   Is there any way to get the http_code on avformat_open_input or
introducing my own AVERROR(http_code) and patching libavformat/http.c is
the only way to do that?

Best regards,
Alex.

Subject: [FFmpeg-user] Movie Filter No Longer Working with PNG Image
Message-ID: <F1184DC6-CCB5-43C0-A36C-EB34271EE8E1@syntropo.com>

Greetings,

I seem to be having trouble with a build from 9/28 when trying to use the movie filter with a png image:

ffmpeg -filter_complex 'movie=in.png' out.png

This same command is working correctly in a different build from 7/2 (on OSX) and this more simplified syntax works correctly too, so it doesn't appear to be a problem with the files:

ffmpeg -i in.png out.png

And jpeg files work perfectly - the issue is just with png. Below is debug output from running these two commands on the newer build, followed by corresponding output from just the first command on the older one (which is actually producing the correct file despite the claim of '0 frames successfully decoded'). 

The only difference I notice is the use of png_pipe to decode the input on the newer build, which doesn't seem to be an option on the older one. Is there perhaps some way to get the newer build to not use this decoder? Or maybe some new syntax that's missing? Any help would be greatly valued, as the filter_complex syntax is extremely convenient for my app to utilize. 

Thanks for your attention,
doug

Kill it nice then. This is inevitable with mp4 format, which adds the
moov atom once it has finished doing everything else with the file -
if you kill it uncleanly, you do not give ffmpeg a chance to add the
atom, and you end up with a bust file.

Alternatively, use a container format that does not have this
restriction, like mpeg-ts.

I tried to reproduce this with testsrc, otherwise using the similar
(video!) properties and arguments as you, and I don't see any issues.
Perhaps you can try with testsrc as well?

*******************************************************************************************
testsrc input and even in my case giving local file as input is working well at my end. I am facing this issue when i am receiving stream from network.
In my Scenario I am sending UDP stream from machine 1 using VLC and receivng this UDP stream  on machine 2 by ffmpeg command. Playlist.m3u8 file  skips last segment entry.
Last segment out005.ts is vailable on my machine and it is having valid data also ,Please let me know why playlist.m3u8 is skipping last segment entry while receiving UDP stream?

The problem is gone with the latest Zeranoe build:

Audio is detected and exported as it should.

Try ffprobe; I'm not familiar with HLS but as far as I know it's a list of

Subject: [FFmpeg-user] Creating screencap mosaic sheet issues
Message-ID: <CAHfRhB_n9=7SBDuJHBgpomi0GZsKO248bLmjEjMeVVmtksXMyw@mail.gmail.com>

I'm trying to create a screencap mosaic sheet similar to what is shown in
https://trac.ffmpeg.org/wiki/How%20to%20take%20multiple%20screenshots%20to%20an%20image%20%28tile%2C%20mosaic%29
.

I'm running into a few issues:

   - Firstly, I can't seem to figure out how to set the screencap interval.
   I need to set the interval to 5 seconds.
   - Secondly, I've played with some variations of the command and what
   seems to be happening is the same sheet gets duplicating 5 times before
   moving on to the next.


Screencap mosaic jpg images with the following specs need to be created:

   - 5x5 tiles
   - images must have a resolution of 160x90 @ 16:9
   - the screencap interval must be 5 seconds.
   - These must be created for the duration of the video.


Here is my command line (running the latest zeranoe windows build):
ffmpeg -i video.mpeg -vf
"select='isnan(prev_selected_t)+gte(t-prev_selected_t\,5)',scale=160:90,tile=5x5"
-qscale:v 3 -y %02d_sheet.jpg

Can anyone help?

Subject: [FFmpeg-user] How does the mkv demuxer really work?
Message-ID: <20141008133750.2145ad02@rivendell>

Hi

I have a question that is perhaps in between ffmpeg-user and
ffmpeg-devel. In doubt, i sent it to this ML.


First: a few words on the background and the problem:

I am trying to create a solution for realtime streaming of transcoded
AV files that supports seeking in the media.
That is, a web server that serves local videos, but, upon request, it
does not serve the video "as is", but it transcodes the video and
stream it to the client via http.
This would be very easy with ffmpeg, however i want to also offer to
the client the possibility to seek in the media.


So, the way i thought of doing this is :

0) transcoding using only h264 and a fixed keyframe interval (say 250
frames, for example).

1) using matroska as media container

2) generating a valid matroska header that contains an artificial
position (offset) of the cues, since the server does not know the
position until it finish transcoding the whole file, which is not gonna
happen by design.

3) generating a valid, but artificial, cue block, containing <movie
lengthinsecs/keyframeintervalinsecs> number of cue points, with correct
time points, but an artificial offsets (see below).

4) using a custom web server that is able to recognize the cue block
offset in the header, and serve the artificial cue block of point 3)

5) making the custom web server also interpret the artificial offset of
3) in order to extract the time offset from the byte offset of a seek
request.

6) making the custom web server start a new ffmpeg -ss <appropriate
time offset> upon each seek (= range http request that is not a cue
block request)



So, i started to prototype this tool ( you can find my very first ugly
attempt that does not work here:
https://github.com/paoletto/mediastreamer )

What i discovered is that the behavior of the ffmpeg matroska
demuxer used in players like mplayer or mpv-player is very predictable
using a valid mkv file (that is, with correct header and cues).

What it does (seeing from the requests received server side) is:
- start reading from the beginning.
- upon the first seek request, the player sends a range http request to
  the cues offset and retrieves the cues
- then, upon each seek, the player sends range http requests to the
  server, with offsets that match cluster offsets (this is more or less
  true. I noticed that, for example, mpv-player requests exact cluster
  offsets, while mplayer requests offsets that are a little bit before
  the cluster boundaries, but still very close)

Now, this all looks well, but when i feed my artificial cue block,
containing cue points with offsets that are , say, multiples of 10000
(or whatever other amount i tried), then the requests that arrive to
the server make no sense, like if the demuxer in the player completely
ignores the cues, and start firing range requests to euristically find
the positions.

My question is then why this different behavior? and how does the
matroska demuxer really work?


thanks and sorry for the long message


ps. i suspect that, even if the demuxer behavior can be tamed, to get
the whole idea working, we (i) would possibly need to run a modified
version of ffmpeg server side, as, from what i understand, the demuxer
needs correct time offset in the clusters it receives.

You're going wrong in that you're not showing us the complete output of
your commands. That would be a good start for understanding what is
going wrong.

Message-ID: <205DBBE9F739414F9815C142C7EA61CC03619179@exchsvr01.torcrobotics.net>

Killing it nicely is not an option. I was under the impression that creating a fragmented mp4 would change the location of the moov atom so the file is still playable, which I verified to be true in my original post with the command:

ffmpeg -f dshow -i video="UScreenCapture" -vcodec libx264 -r 25 -q 5 -preset ultrafast -movflags frag_keyframe  C:\Users\user\Desktop\video.mp4 -y

Files created with that command can be killed not-nicely and are still playable. What I am after is creating this same fragmented file but with segmented file creation enabled so I don't get one huge video file if it runs for hours.

Thanks,
Mark

Through some trial and error I got what appears to be a reasonable
output using the following command line:

ffmpeg -i D:\movies\input.avi -vf
"fps=fps=1/5,select='isnan(prev_selected_t)+gte(t-prev_selected_t\,5)',scale=160:90,tile=5x5"
-qscale:v 3 -y %03d_sheet.jpg

My input file was a 23.98 fps, which I rounded up to 24. I added
"fps=fps=1/5" to what you already had in your options. I arrived at
1/5 frames per second by multiplying the frame rate of the input by
the interval at which I wanted thumbnails to be captured and then
dividing that number by the number of thumbnails in each output file.
This was just a guess and I'm not sure if my logic is correct or I
just got lucky. I only verified my results by eyeballing it and seeing
that the number of thumbnails was in the ballpark of the length of the
movie in seconds divided by 5.

	drawtext filter
Message-ID: <543640F7.90606@vitec.com>

Hello

I'm using the drawtext filter to burn in the timestamp.
drawtext=fontfile=FreeMono.ttf:shadowcolor=white:shadowx=2:shadowy=2:x=10:y=19:timecode='12\:49\:18\:00': 
rate=*25*:fontsize=22:text=\'7.10.2014 \'

But with this filter i can only handle videos with framerate=25
Who can i use the filter with autodetect rate.
I must handle 50 fps likewise 25fps

whole command:

ffmpeg -i

mpeg output format might satisfy better here?

Subject: [FFmpeg-user] rc buffer underflow
Message-ID: <5437B2C9.5070602@ucweb.com>

Hi there,

I am new to ffmpeg. I have a question in capturing video stream with my 
camera.

Firstly, I clone current repository from github. And then, run 
./configure && make.

Secondly, start ffserver as below.

$ ./ffserver -f tests/ffserver.conf

Then, try starting ffmpeg to activate my camera.

$ ./ffmpeg -f video4linux2 -i /dev/video0 http://127.0.0.1:9999/feed1.ffm

Then, it complains rc buffer underflow repeatedly as below.

Anyone know how to solve it? How to enlarge lmax or qmax? Correct me if 
I do something wrong. Thanks first.

What that doesn't tell you though is that you need libsdl, and it needs
to be found, in order to have ffplay included in the build. You need
SDL-devel or libsdl1.2-dev or whatever it may be called on your
distribution.

You also need some other libs, notably X11 libs, as the note in this
document hints:

https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu#GettheDependencies

> [...] ffplay and x11 dependencies: libsdl1.2-dev libva-dev
> libvdpau-dev libx11-dev libxext-dev libxfixes-dev

(These package names are for Ubuntu. The RedHat/Fedora/CentOS wiki page
isn't so clear about this.)

Message-ID: <DUB109-W328B8EE68ED33A2636782D94A30@phx.gbl>

hi all,

i've been trying to solve a strange problem but i'm not really getting anywhere, so i'm hoping to find an expert here ...
basic situation is i have a raw h264 encoded video and want to mux it into an mp4 container. no audio. no re-encoding.

so i do: ffmpeg -i snippet.h264 -r 25 -c:v copy snippet.mp4

however, this does not seem to work. error message: Output file is empty, nothing was encoded

what am I doing wrong?

sample file can be found at: http://s000.tinyupload.com/?file_id=78774328066008732903

thanks
peter

Subject: [FFmpeg-user] MXF encoding, right audio channel delayed
Message-ID: <1412852726397-4667711.post@n4.nabble.com>

I have a big problem: We use ffmbc to encode proes files to mxf with
dedicated mono audio channels:

-ss 00:00:00 -i "<FullSourceFileName>" -target xdcamhd422 -an
"<OutputPath><OutputFileName>_MXF.mxf" -acodec pcm_s24le -ar 48000 -newaudio
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:0:0:0:1:0
-map_audio_channel 0:0:1:0:2:0

I have noticed that the right audio channel is delayed by 1586 samples, or
about 38 ms. Why does this happen? Is there any chance to fix this issue
without reencoding the complete file?

Thanks!

Ok, I've found the cause. Sometimes it is nesscary to trim the first 5
seconds of videofile. Therefor I use "-ss 00:00:05". The result is:

I have setup a ffmpeg and I'm streaming a file from localhost to rtmp
server.
What i need is to stream a file from the client PC.

i.e., I am hosting ffmpeg on the server and i need my web application to
streams the file from the client PC to the rtmp server. Is it possible?
 I don't want to upload the entire file to my server because sometime the
files are from a live feed (mixer studio outputs)

I have a PNG image and a video file and I want to merge them together into one video file. All of the work should be done under Linux.
1. The PNG image has 1280x720 resolution and I converted it to *.mp4 file using the following command:
$ ffmpeg -loop 1 -r 24 -i image.png -t 00:00:05 -vcodec h264 -pix_fmt yuv420p -an image.mp4

2. The video was created via pipe using the following command (pay attention to its last line):
$ gource -s 2 --auto-skip-seconds 0.1 --file-idle-time 0 --max-files 500 --multi-sampling --bloom-multiplier 0.9 \
--bloom-intensity 0.4 -1280x720 --stop-at-end --output-ppm-stream - history.xml \
| ffmpeg -y -r 24 -f image2pipe -vcodec ppm -i - -vcodec libx264 -preset ultrafast -pix_fmt yuv420p video.mp4

3. Then I merged them in one video. The list of input files:
$ cat files.txt
file 'image.mp4'
file 'video.mp4'

This command was used to concatenate the files:
$ ffmpeg -f concat -i files.txt -c:v copy result.mp4

This command printed the following message, not sure if it is important:
[concat @ 0xc83b90] Estimating duration from bitrate, this may be inaccurate

4. Finally, I open result video with mplayer. I see the first image for 5 seconds, as expected. Then, when the second video should start, mplayer "hangs" and the following messages appear in the console:

Hi,

I am developing open-source framework that is licensed under LPGL and it is
mainly focused on graphical usage. I am also developing addons for this
framework and one of which is video player that uses FFmpeg libraries.

My question is, if I compile shared FFmpeg libraries *without* parameters
"--enable-gpl" and "--enable-nonfree" to make it LGPL compatible, then am I
legally allowed to make DDLs available on framework`s git repository? If I
understood right, I also need to make the source code available on same
repository from which DLLs were compiled?

My last question. I am also making closed-source app that is using my
framework also with addon that uses FFmpeg libraries and clients will not
be charged for this app. In order to ship the application I also need to
ship FFmpeg DLLs with exe in order to make app properly working. I am only
using shared libraries, not static. Do I need to include FFmpeg lib source
code into application? If yes, would it be OK if I only provided link to
repository (in which DLLs with source code and my framework are) inside
app`s readmy file?

Thank you.

with regards,
Matus Novak

Message-ID: <CAO_ZARb7NNUAKtxdEbszy5tn_KQ+Ht54Yn0ak8Tpvzh4JKKqog@mail.gmail.com>

I am trying to build an LGPL version of ffmpeg.
I am following instructions from https://www.ffmpeg.org/platform.html
section 4.3 4.2 Microsoft Visual C++ or Intel C++ Compiler for Windows

Let me know if there is a better instructions list to use.
I got as far as
./configure --toolchain=msvc
After I ran msys.bat it started I believe MINGW32 bash in which I went to
the directory where I downloaded source from
http://ffmpeg.zeranoe.com/builds/ and I ran ./configure --toolchain=msvc
I got back this:

$ ./configure --toolchain=msvc
cl is unable to create an executable file.
If cl is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

I attached the config.log here

Thank you in advance for your help.

if you use "--enable-gpl" you need to follow the GPL
if you use "--enable-nonfree" the binary is *undistributeable*

at the end you need to consult a laywer, this is the wrong place
there is a good reason why you find only sources on the official page

patent issues and so on.....

This version is way too old. Use a recent one or build your own from
git.

Because it works for me (two week old snapshot), see below.

I believe this means you ignored the first "Note" in 
the documentation for msvc compilation.

I am not sure if I understand the question:
(I am not a native speaker.)

If you compile FFmpeg with --enable-nonfree, you are not 
allowed to distribute the resulting binaries. If you 
compile with --enable-gpl, you are allowed to distribute 
the binaries if you comply with the rules of the GPL.
If you use neither --enable-nonfree nor --enable-gpl, 
you may distribute the resulting binaries under the 
rules of the LGPL.
We have written a page that makes it - in our opinion - 
easy to check if you follow all LGPL requirements:
https://www.ffmpeg.org/legal.html

> If I understood right, I also need to make the source

You have to make sure that users can (easily) download 
the exact sources that you used to compile the binaries 
based on FFmpeg source code (the "DLLs").
I am not sure what you mean with "same repository": If 
your binaries are not typically downloaded through a 
web browser (but through an installer program), then it 
is important that your users may click on a link to the 
source code. I believe we do explain this on our 
checklist: I suspect you somewhere (on a webpage) provide 
a link that will be used by the installation program. 
Just put a link to the source code next to the link to 
the app. (And you should of course mention that the 
source code is not needed to run your app.)
(And we believe that it makes sense to host the binaries 
and the source code on the same server, but this is of 
course no requirement, the requirement is that users may 
download the sources if they want to do AND that they 
can switch the "DLLs" you provided with DLLs they 
compiled themselves.

All the above is relevant no matter if the executable 
that calls the "DLLs" is licensed under LGPL or is 
proprietary and it makes no difference how much you 
charge for the executable.

Don't forget that you also have to tell your users about 
FFmpeg and the LGPL.

I am not a lawyer, it may be necessary that you consult 
your lawyer.

It is very unlikely that above command (that requests 4:2:0) 
was used to produce the input file (that has 4:4:4).

You can only use concat on two videos with the same (very 
similar) properties, ie you need the same pix_fmt for both 
input videos.

Subject: [FFmpeg-user] Right audio channel shifted
Message-ID: <1412974802235-4667730.post@n4.nabble.com>

Hi all,

I normally transcode MY prores files to mxf/xdcam422 and 2 dedicated pcm
audio streams with ffmbc, which basically works very well.

Due a bug in ffmbc 0.7-rc7
(https://groups.google.com/forum/#!topic/ffmbc-discuss/6rqUhyG4Wv8), I have
recognized yesterdaym that the second audio stream of some of my files is
shifted by about 40ms.

I've had a look at the ffmpeg manual and found "atrim" as one possible
solution for my problem. Is there maybe a smoother way to get the audio
channels back in sync?

Best,
Alex

I (strongly) suspect this is the only dependency for 
ffplay, the other libraries are needed for other 
features.

Concerning "--enable-ffplay": I just like to add that 
this should not be part of any sane configure line, it 
does NOT do what most people expect, ffplay is built 
if libsdl-devel is installed.

Hi,

I've been trying to get my decoder to read my UDP feed but for some odd
reason it doesn't like when I add the ?pkt_size=1316 option to my unicast
stream.

>From reading around I am aware that I can recompile ffmpeg with a custom
MTU setting to ensure I can get the desired packet size, however my
question is if there is another way to insert the MTU override setting in
the CLI without placing it right at the end of the stream?

Command is:

ffmpeg -re -i rtmp://x -vcodec mpeg2video -r 25 -flags cgop+ilme
-sc_threshold 1000000000 -b:v 2M -minrate:v 2M -maxrate:v 2M -bufsize:v

Message-ID: <DD192F0F-3010-4733-B6CD-975B70D7D807@apost.plala.or.jp>

Hello, 

I am trying to hardcode dvd subtitle into video referring the link below 

https://trac.ffmpeg.org/wiki/HowToBurnSubtitlesIntoVideo


The command line I tried is the following.

$ ffmpeg -analyzeduration 60M -probesize 60M \
-i /Volumes/DVD_VIDEO/VIDEO_TS/VTS_01_1.VOB \
-filter_complex "[0:v][0:s]overlay[v]" \
-map [v] -map 0:a -t 00:05:00 test.mp4

The command line works fine and I can get a mp4 movie with subtitle.  But I got yellow colored subtitle.  I'd like to change subtitle color into yellow to white if I can.

Is there any way to change overlay color of subtitle?

Only of text subtitles.  DVDs have vobsub subtitles which are bitmaps.
This means it can't be as easy as setting "color=white".  There might be
some complicated way of altering the colours of the bitmaps by
saturation, brightness, or just a lut.

If they are vobsubs, you could split them out into a track.idx/track.sub pair with, for instance mkvextract.

Looking at the .idx file, I see it has a line at the start:

palette: 000000, 0000ff, 00ff00, ff0000, ffff00, ff00ff, 00ffff, ffffff, 808000, 8080ff, 800080, 80ff80, 008080, ff8080, 555555, aaaaaa

Changing that would presumably change the color of the subtitles.

mkvmerge can pull the subtitles back in.

So what i would suggest is


#remux subtitles
ffmpeg -analyzeduration 60M -probesize 60M -i /Volumes/DVD_VIDEO/VIDEO_TS/VTS_01_1.VOB  -vn -an subtitles.mkv

#pull out .idx/.sub pair
mkvextract tracks subtitles.mkv 0:subtitles.idx

$??edit that line to change the colors??

#put the .idx/.sub pair back together
mkvmerge -o newsubs.mkv subtitles.idx


#use that new subtitle stream
ffmpeg -analyzeduration 60M -probesize 60M \
-i /Volumes/DVD_VIDEO/VIDEO_TS/VTS_01_1.VOB \
-i newsubs.mkv \
-filter_complex "[0:v][1:s]overlay[v]" \
-map [v] -map 0:a -t 00:05:00 test.mp4

I have no idea if changing the palette line will work.

I know that vobsub subtitles are bitmaps.  But in a original DVD, the subtitle are white bordered in black.  I don't know how ffmpeg process those subtitle, but I think ffmpeg intentionally change the color of subtitle.  Am I wrong?

Thanks for procedure.  I don't tried it yet.  But this procedure is based on changing color of original dvd-vobsub.  Am I right?

Do I need this procedure even if original dvd-vobsub is white bordered in black when watching original DVD with player?

I heard that the color is intentionally changed by ffmpeg.  Am I wrong?

I don't think it is supposed to do that but I am not at all familiar
with subtitles in FFmpeg.

In DVDs, the subtitles colors are stored in the IFO metadata file. Your
command line does not use that file (and actually, FFmpeg is not capable of
taking advantage of it yet), so the palette is lost.

You can override the palette using the -palette option to the dvdsub
decoder.

If that does not work or if it is not powerful enough, remember that once
you use the bitmap subtitles in the filter graph, they are actually treated
as video (with alpha). So you can use all video filters, and amongst the
various hue and lut filters there is probably one that can change the
colors.


As a side note, I see your command line accesses the VOB files directly in
the DVD-Video file structure. That is almost always wrong. You need to use
DVD-Video-aware software to reconstruct the MPEG streams correctly. You can
use the dvd2concat for that for example, or mplayer -dumpstream.

Regards,

Thank you very much.  Now I understand why my command line produce yellow colored subtitle.  Also I understand how to change the color using -pallet option.

Message-ID: <CAJB=bRZAeDV96813s0FmfaMmbSEZR9ajjQV9UGK4Z9BZHRkuDQ@mail.gmail.com>

Hi,

I'm not able to get seek (ss) working with the concat demuxer,
is this supported or can anybody spot what I'm doing wrong?

The command I run to seek 20 seconds into the concat is:

ffmpeg -f concat -ss 20   -i test.list  -vcodec copy -acodec copy -f flv
rtmp://localhost/live/hello

test.list contents:

test1.flv
test2.flv
test3.flv


I verfied if I just pick one file, the seek (ss) works within it:

ffmpeg -f concat -ss 20   -i test1.flv  -vcodec copy -acodec copy -f flv
rtmp://localhost/live/hello


Any ideas?

Thx.

Two observations, firstly this is the ffmpeg mail list *not* ffmbc so
not really the place to ask such questions. The common codebase for the
two projects is some way back so what is relevant for one may not be
relevant for the other.

Secondly, is your source file by any chance a .mov? Some files in this
format created by ingesting from tape have the first (and may be more)
frame flagged as being of a different duration to the actual value
calculated from the frame rate. This can cause issues for ffm*.

If you drop the whole '-ss 0' is there a difference?

Hey, verify packets size with Wireshark.
You can also add -flush_packets 0, to be sure that all packets will have
1316 bytes.

Hi,

I've been trying to get my decoder to read my UDP feed but for some odd
reason it doesn't like when I add the ?pkt_size=1316 option to my unicast
stream.

>From reading around I am aware that I can recompile ffmpeg with a custom MTU
setting to ensure I can get the desired packet size, however my question is
if there is another way to insert the MTU override setting in the CLI
without placing it right at the end of the stream?

Command is:

ffmpeg -re -i rtmp://x -vcodec mpeg2video -r 25 -flags cgop+ilme
-sc_threshold 1000000000 -b:v 2M -minrate:v 2M -maxrate:v 2M -bufsize:v 0.2M
-muxrate 2.5M -acodec mp2 -ac 2 -b:a 224k -f mpegts udp://
192.168.0.4:1234?pkt_size=1316

Thanks in advance.

ffmpeg is your encoder and some other program is your decoder, right?
And that other program doesn't cope with '?pkt_size=1316' in the URL?

Your decoder doesn't need the "?pkt_size=1316" part of the URL. Just
omit that on its side.

Thanks for the suggestions, as far as the flush packets command is
concerned I will try that today.

But in respect to omitting the command from decoder side, this isn't
possible as the decoder is set up to receive streams directed to its IP.
And as such, I cannot configure it to receive the stream without the
pkt_size option.

The problem is that it simply doesn't recognize the stream with the added
option. It's an Ericsson RX8200 in case anyone is wondering.

BTW, this is somewhat different from what I expect from my experience
with autoconf based configure scripts. Note that this is possibly a
matter of taste, and that autoconf based scripts may differ in their
behavior as well.

This is what seems logical to me:
- Say nothing about a feature. The configure script decides what is
  default, and what to do if something can't be fulfilled (like to omit
  a feature).
- --disable-feature: Whatever the default is, don't include this, and
  don't error out if its (unique) dependencies aren't fulfilled.
- --enable-feature: Whatever the default is, try to include this, and
  error out if it can't be fulfilled.

ffmpeg's configure behaves differently. "--enable-ffplay" will just
confirm the default behavior, but still silently not build ffplay.
Well, not so silently, as the missing of SDL is reported (and probably
the resulting missing of ffplay). But this gets lost in all the
messages, and configure still creates its Makefile(s).

The same with enabling e.g. the filters that require font libraries. I
believe if you figure out that you're missing drawtext, then rebuild
with "--enable-filter=drawtext", you still won't get it if you're
missing freetype-devel.

I realize this is or may be a design decision regarding configure. I
just want to point it out, as it seems a bit confusing to me. I have
explicitly tripped over both of these issues. ;-)

Cheers,
Moritz

Dear list,

-vf hue=b=-10 does not result in black images depending
on colors. 

Is this expected behavior?

I tried to use the hue filter in combo with sendcmd to 
simulate fade in and out but failed miserably.

#!/bin/bash
a2z=($(echo {a..z}))
for i in $(seq -10 10);do
     t=${a2z[$i+10]}

done

Message-ID: <CACuV5sCaiAK-HC49k_+7hvR5UrA8K5eNxwq2fNrtCOk6Ndiw3w@mail.gmail.com>

Hi:

I have been trying to remove the static background (both mp4 and png
backgrounds alternatingly) from the video, but without success.

I used in a single line:

% ffmpeg -report -y -i "FORGROUND.mp4/png" -i "BACKGROUND.mp4"
-filter_complex
"[1:v]format=yuva444p,lut=c3=128[video2withAlpha],[0:v][video2withAlpha]blend=all_mode=difference[out]"
-map "[out]" "OUTPUT.mp4"

where:

1. BACKGROUND.mp4/png is the video/static picture without any moving
objects respectively.
2. FOREGROUND.mp4 is the moving object in front of the BACKGROUND as in 1 above
3. OUTPUT.mp4 is the result file.

Appreciate any input from expert ffmpegers here to make this happen. Thanks!

Yes, that's what I tried to explain: FFmpeg's configure 
script is not autoconf-based.

The important thing is that --enable-ffplay is mostly a 
debug option and should not be part of any user's 
configure line.

Yep, I've tried ffmbc 0.7.1 and it works fine now. But I have to bring the
audio back in sync for approx. 80 files.

Do you have any suggestions?

Okay, I played a bit around with the atrim Filter, but the manual isn't very
helpful here. I've tried the following:

C:\>ffmpeg -i test.mxf -vcodec copy -map 0:v -acodec pcm_s24le -map 0:1 -map
0:2 -filter_complex "[a:1]atrim=start=0.035" test_new.mxf

I guess there is somehing wrong with the channel mapping, but without the
fliter_complex the mapping seems to be okay.

Thanks,

Hi Alex,

> fliter_complex the mapping seems to be okay.

I think the filter_complex messes up the mapping. Note this mapping
from your output:
> Stream mapping:
>   Stream #0:2 (pcm_s24le) -> atrim
>   atrim -> Stream #0:0 (pcm_s24le)
>   Stream #0:0 -> #0:1 (copy)

and this result:
> Output #0, mxf, to 'test_new.mxf':
>     Stream #0:0: Audio: pcm_s24le, 48000 Hz, mono, s32 (24 bit), 1152 kb/s
>     Stream #0:1: Video: mpeg2video, yuv422p, 1920x1080 [SAR 1:1 DAR 16:9],

and this warning:
> [mxf @ 00000000003b69c0] there must be exactly one video stream and it must be the first one

I'm sure that's your issue. The filter seems to be messing up the
mapping, at least in this automatic case.

Instead of

> C:\>ffmpeg -i test.mxf -vcodec copy -map 0:v -acodec pcm_s24le -map 0:1 -map 0:2 -filter_complex "[a:1]atrim=start=0.035" test_new.mxf

you probably need something like

ffmpeg -i test.mxf -vcodec copy -map 0:v -acodec pcm_s24le -map 0:1 -filter_complex "[a:1]atrim=start=0.035[ashifted]" -map "[ashifted]" test_new.mxf

(Untested) Note that I'm trying to explicitly map the filter output to
a particular stream, avoiding automatic mapping. You may have to play
around a bit more with the map options.

Is this a bug, BTW? Documentation on "-map" states:
>    The first -map option on the command line specifies the source for
>    output stream 0, the second -map option specifies the source for
>    output stream 1, etc.

Digging further, documentation of "-filter_complex" clarifies:
>    Output link labels are referred to with ?-map?. Unlabeled outputs
>    are added to the first output file.

So the first documentation section is somewhat unclear, as it is
"disturbed" by the second behavior. (And in the second section: "first
output file" -> "first output stream", right?)

Subject: [FFmpeg-user] Start time/duration question when transcoding to
	WMV/WMA
Message-ID: <CAEnqZEUnkSVO-=ETfH0Et7CPbE=o+eeAQUSbkYYSfhP5ba3DJg@mail.gmail.com>

I observed that start times and durations changed when transcoding
whatever input (tried a few) to wmv/wma in a wmv container.

Here's a sample command line with output:

ffmpeg -f lavfi -i testsrc=s=640x480:d=1 -f lavfi -i

Is this due to encoder delay of WMA (2064 samples?) and is OK in principle?

Dear All,
Just joined the mailing list.
Looking for a video player in a browser,  that will play:
mp4 video codec, aac audio codec, and floor audio, en, fr, ger, tr translations.
Each audio channel will be selected in the browser in most platforms.
I have managed to:
ffmpeg -i 00.mp4 -i 01.mp4 -i 02.mp4 -i 03.mp4 -map 0:0 -map 0:1 -map 1:0 -map 2:0 -map 3:0 -acodec copy -vcodec copy output.mp4
where output.mp4 is the video file with 4 audio stream muxed together. Now how can i play it in a browser.
Regards,
Celal Yasar Sahinoz

Hi Moritz,

thanks for your help, works great! The mapping thing is still a bit
confusing to me. :)

One last problem: I would like to set the sample format of the second stream
back to s32. I tried the follwoing, but it won't work:

ffmpeg -i test.mxf -vcodec copy -map 0:v -map 0:1 -sample_fmt s32 -c:a:0
copy -c:a:1 pcm_s24le -sample_fmt:a:1 s32 -filter_complex
"[a:1]atrim=start=0.035[ashifted]" -map "[ashifted]"  test_new.mxf 

Thanks,
Alex

In this case, since you didn't include the output, I was quite lost. I
use "-loglevel debug" to inspect the filter chain, by the way.

Using one artificial audio source, I was able to experiment a bit.

It appears that it's only the default output of pcm_s16le that is
incorrectly selected for you, your choice of -c:a pcm_s24le is fine,
and atrim seems to handle s32 fine.

In other words: "-c:a:0 copy -c:a:1 pcm_s24le" should work fine in your
case, you can omit "-sample_fmt:a:1 s32". Furthermore, I was able to
make "-c:a:1 pcm_s24le -sample_fmt:a:1 s32" work. Perhaps your first
"-sample_fmt s32" is incorrect (apart from being unneeded). I can't
even tell what it applies to.

As I said: No output messages, no idea. :-)

Subject: [FFmpeg-user] Any ffmpeg plugin for image stabilization that
	handles walking tilt?
Message-ID: <CACGw4H4VpVTSv+AOEv-njinsdvaKdux7zq-_QWmZX-egSDBBCA@mail.gmail.com>

Hi there.

I have begun playing around with using a wearable camera that just clips
into your shirt, like w mic clip.
It records MJPEG at 720x480 which is enough for my uses, recording daily
walks around the city.

But there's one issue I had not taken into account: the body (actually
torso) where the cam is attached to moves a LOT while walking, you might
not perceive it since your neck/head does a lot of stabilization on its
own, coupled with any built-in image stabilization done by the brain (great
firmware!).

I was shocked when I first saw the recording of me walking very fast, it
looked as if was recoded from a helmet cam by Godzilla rampaging throughout
the city.

The problem is not only the shacking but the TILT. The body tilts a bit
with each step.

I have read here about the "deshake" option in FFMPEG
http://adaptivesamples.com/2014/05/30/camera-stabilisation-with-ffmpeg/

But I'm curious as to what algorithm it uses, or if it is tweakable at all
to compensate for side-tilt while walking in addition to vertical shake.

Someone on the above post talks about the
vidstabdetect and vidstabtransform filters, but without giving further
detail on why those are better.

Looking around, I came across this IEEE research paper (sorry,I could only
read the abstract, don?t have access to it)...

"A physiological camera shake model for image stabilization systems"

That seems to address specifically the complexities of stabilization needed
due to walking.
?
http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6127172&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D6127172

" It successfully reproduces subjective observations made about the shape
and time evolution of hand tremor-induced motion blur patterns. Our model
is compared to the simpler random-walk and straight-line-walk models as
well as previously reported experiments. It paves the way towards accurate
deblurring and optimal image stabilization algorithms by providing
realistic motion blur point spread function matrices. To our best knowledge
it is the first model in which both spectral and statistical
characteristics fit several ground truths from literature."

In short: I?d like to know if there?s any FOSS filters -both for FFMPEG and
third party ones for ie Virtualdub or Avidemux, that represents the
state-of-the-art in image stabilization post-processing wrt to walking
recordings...

Thanks in advance!
FC
PS: I know what some of you will say: Just wear the camera above your head,
not below your neck. Well, that's not an option for me.
PS2: I?m crossposting on the dev list in case any devs are likely more
aware then users...

Thanks for your time Moritz.

You are right, I forgot to remove the first -sample_fmt 32, sorry. I run the
command again:

C:\>ffmpeg -i test.mxf -vcodec copy -map 0:v -map 0:1 -c:a:0 copy -c:a:1
pcm_s24le -sample_fmt:a:1 s32 -filter_complex

One other thing: I checked my database again and I have to verify over 300
videos which are possibly affected by this bug. Is there a possibility with
ffmpeg to repair those files automatically or at least see if a file is
affected. Otherwise I am going to do this job manually via a vectorscope. :)

  friend Fernando

I do not have a direct reply to your questions.
But rather a comment - I have recently been reading about how the 
"softwear" of human perception that allows us to all "deal with" the 
shaking of our vision and how we smooth that out.
and and how that is defeated when we have objective video in the raster.
  ---  fascinating stuff how we throw away and filter our perception.

best of luck with your deshake.

maybe a pocket protector-steady cam device would be a solution ... ;)

for fun

I think I have read something, but can't recall where.

That said, have you looked at the examples?
http://public.hronopik.de/vid.stab/features.php?lang=en
Though thay may not specifically involve your combination of vertical
and horizontal tilting, I do find them quite convincing. (I only have
a little bit of experience with less wiggled input though.)

How about just giving it a try?

Dear Sir or Madam:

        I'm working with the monitor and using the ffmepg to make a player  but it failed when I was configuring the ffmpeg with a note:ERROR:   libx264 not found .
        I have  done such work before the upper working including  downloading the sdl1.2,x264,libvpx and configuring them without error.My final destination  is that using

       I am looking forward your replay and thank you!

avisynth and vdub both have open source deshake/vstab filters and
plugins.

google diy steadicam
many you can make for $15-$30
http://14dollarstabilizer.org/

the human walk image stabilizing filter you want would probably take 1-2
years to develop from scratch.

>MJPEG at 720x480

seriously? is this 2003?
image stabilizing software will work better on higher resolution video
and better codecs. lossless is best, but h264 will work better than
mjpeg too.

and you'd want higher fps to get more image data. otherwise it will be
all blur.


ok now that i'm done insulting your pathetic camera, how about sharing
with us a sample video (uncompressed original mjpeg file) of your
walking so we can see and/or fix our deshake algorithms?

Please show us your ./configure command line and attach the resulting
config.log file.

You may also want to show us the ./configure line you used for libx264.

If you are using Ubuntu, try

sudo apt-get install libx264-dev

I am a new user to ffmpeg too. The senior user kindly gave me a useful 
link about compilation.

Hi:

New to ffmpeg. How can one create a trapezoid shaped video as a
overlay to the background as seen at
http://www.youtube.com/watch?v=_380o5B9MrA (starts at 00:02:25) using
ffmpeg command?

Thanks!

Okay, when I check the trimmed file with ffmpeg it looks okay:

But: "[mxf @ 0000000000350280] index entry 5095 + TemporalOffset 1 = 5096,

What does this mean?

An why does VLC identifies different channel values?

Using the binaries from http://johnvansickle.com/  I get an error when using

The error from http://johnvansickle.com/ffmpeg/ is the same for the nightly
and version 2.4. The gusari.org binaries havent been built since July 16,
for now I am using ffprobe from gusari for http sources and for file sources
johnvansickle.  From where are you getting your (supposedly stable)
binaries?

Ubuntu x86_64 GNU/Linux

Subject: [FFmpeg-user] Slideshow+audio causes huge amount of memory allocated
Message-ID: <CAHss8oFbqHTgZ_9eVrOr0Vtkn26s3DjwrhTAV2q_1sAVP_-BOw@mail.gmail.com>

hello,
the following command line plays a web radio while showing a picture slide
show.

ffmpeg -loop 1 -framerate 1/10 -i img%3d.png -i http://webradio:port
-vcodec rawvideo -pix_fmt yuv420p -vf fps=fps=25 -acodec pcm_s16le -ac 2
-af aresample=48000:first_pts=0,asetnsamples=n=1920:p=1 -f asf - | ffplay -

The longer is the time between pictures, the bigger is the memory allocated
(> 1gb).

I suppose this is caused by fps filter that every 10 seconds generates 250
frames and the multiplexer, trying to keep proper interleaving, buffers a
lot of frames.

Can you suggest some alternative that allow me to do this in realtime? (the
script should run 24/7)

thanks,
MB

I build them myself, and on some machines just stick to
Fedora's/RPMFusions's version as distributed in the repositories.

Tried with this build, still doesnt work for me using an http://... input:  
... 
"[tcp @ 0xbf594a0] Failed to resolve hostname"

I will try using a repo version, in the past I have also compiled manually
but for this particular project we were after a simpler process to pass on
to the system admins.  Thanks for your feedback!

Subject: [FFmpeg-user] Buffer Underflow in case of high resolution
	mpeg1video encoding
Message-ID: <1413460806577-4667787.post@n4.nabble.com>

Hello,

I've been using ffmpeg to encode raw data using the following command line
argument:

ffmpeg -r 24 -pix_fmt rgba -s 2560x1440 -f rawvideo -y -i - -c:v mpeg1video
-qscale:v 4 -vf vflip filename.mpeg

During encoding I get the following output:
[mpeg @ 000000000434c3c0] buffer underflow st=0 bufi=234679 size=263328
[mpeg @ 000000000434c3c0] packet too large, ignoring buffer limits to mux it
[mpeg @ 000000000434c3c0] buffer underflow st=0 bufi=234679 size=263328
[mpeg @ 000000000434c3c0] buffer underflow st=0 bufi=236708 size=263328
[mpeg @ 000000000434c3c0] packet too large, ignoring buffer limits to mux it
[mpeg @ 000000000434c3c0] buffer underflow st=0 bufi=236708 size=263328
...

I noticed that using a lower resolution, for example 1920x1080, does not
give me a buffer underflow.
Also using a qscale of 5 instead of 4 prevents it.
It's also interesting to note that the output seems to be fine, despite
these messages.

Can someone help me understand what exactly a buffer underflow means in this
context? And/Or how to prevent it from happening? I've searched around for
some time now and I'm still none the wiser.

Much appreciated!
Inge

I can't seem to find a filter which does that directly, but the
"perspective" does a similar transformation, in an inverse way. I
believe it "virtually pulls the given viewpoints to the corners." Using
it with values pointing at viewpoints outside of the frame gives the
approximate effect of what you're trying to achieve, see my example
below. Interestingly, that filter smears the edges colors of the input
across the rest of the output frame. (I'm not sure whether that's a bug
or a feature.)

Here's an example, using a test source with an overlayed outline and
grid lines, to may the effect more clearly visible. It uses the SDL
display driver as output to screen, but you can output to a file
alternatively:

ffmpeg -re -f lavfi -i "testsrc,drawbox=x=1:y=1:w=iw-2:h=ih-2:t=1:c=white,drawgrid=w=iw/10:h=ih/10:t=1:c=white at 0.5" -filter_complex "[0:v]perspective=x0=-100:y0=-100:x2=-100:y2=H+100[ovl1]; [0:v]pad=w=iw*2[ovl0]; [ovl0][ovl1]overlay=x=W/2[vidout]" -map "[vidout]" -pix_fmt yuv420p -f sdl -

I use the "-filter_complex" chain to combine the original and the
transformed output side-by-side. The relevant "perspective" filter
section is:

"perspective=x0=-100:y0=-100:x2=-100:y2=H+100"

Note the reference points _outside_ of the frame to achieve a trapezoid
size reduction. The filter you are looking for should probably accept
actual corner values. That said, such a filter could probably be
derived from the "perspective" filter's code. (I failed at finding an
easy way to do this though.)

Set -bufsize and -maxrate to (very) high values for 
high resolution / low quantiser mpegvideo.
(I am not sure if the resulting file will conform 
to any specification but it will play with all 
open-source decoders.)

Subject: [FFmpeg-user] Question about audio video synchronization in
	containers
Message-ID: <1413550772304-4667793.post@n4.nabble.com>

Dear Sirs and Madams,

I have a question about containers and synchronization of the contained
video and audio streams and hope someone can provide me some basic
information.

How can I guarantee that the muxed/interleaved streams are synchronized in a
container so that there is no delay when played?
Video has timestamps like PTS and DTS. Do audio streams have that too?
Does a container have timestamps or does it work with timestamps provided by
the streams?
Is there a general way of synchronization for all containers (AVI, MPEG, MKV
...)?

Thank you for your time, help and any information or hint that could help me
to understand that matter.

Have a nice day
Seb

-vf  mp=eq2=1.0:1.0:-1:1.0 gives  the very same result like hue=b=-10

e.g:

red,green,blue colors from testsrc when saved w/o filter as png are exactly 
#ff0000, #00ff00, #0000ff as expected.

going thru hue=b=0 or mp=eq2=1.0:1.0:0.0:1.0 the colors are:
#fe0000, #00ff01, #0000ff

however when setting brightness to minimum: (hue=b=-10 or
                                             mp=eq2=1.0:1.0:-1.0:1.0)

the resulting colors (rgb) are:

#a00000, #005700, #0000cf

Is this really the expected behaviour? Simply-minded I expected the
brightness value to act like the brigthness control on a color TV...

Going into YUV vs RGB  pm weekend if time permits..

have a nice weekend,

Subject: [FFmpeg-user] Get H264 NALUs from a muxed file
Message-ID: <CAEQqvtY7LjKUwsVAo+k2c8fXuvxXFgdgnkzpD0qsG3a3j9xfXw@mail.gmail.com>

Hi all,

I have a question regarding demuxing files containing H264 data. I am
trying to demux MP4 files and MPEG2-TS files. I have noticed that when I
read a fram in an AVPacket get whole frame (containing several NALUs) in a
different format, in concret in MPEG2-TS I get the data with the start_code
(0001) to divide the NALUs, but with the MP4 I get the frame without start
codes but 4 bytes indicating NALU size instead. I now this is due each
container specification, but I am wondering if there is a way with FFMPEG
to get exactly the same data regardless the container.

The problem I have is that I want to process certain NALUs so I'd like to
get NALUs one by one in a discrete way, assuming this is not possible with
FFMPEG (at least as far as I know) I am dividing NALUs of the frame one by
one parsing AVPacket data. The problem here is that I have to implement
different parsers for every container. Is there a way to solve this? to get
H264 frames in an standarized way? or even better, is it possible to get
NALS one by one with FFMPEG.

Thanks in advance for any advice about this matter.

Best regards,
David

Ok, I'm not sure what you meant by an easy way, but the formula for what to put into the perspective filter options to essentially have it be the inverse (where to send the corners, not what to send to the corners) is huge mess, so it can't be done easily for any given picture (just change the x0 to a -x0 or whatever). However it might be able to be hardcoded into a different filter (vf_keystone?) I'll inquire on ffmpeg-devel if that is possible, to have one filter basically just call another filter with different options.

For example, if you wanted the original corners to go to x0:y0:x1:y1:x2:y2:x3:y3 the first option (x0 for that filter) you would want to give to vf_perspective is

(W (x2 y0 - x0 y2) (x3 (y0 - y1) + x0 (y1 - y3) + 
     x1 (-y0 + y3)) (x3 (y1 - y2) + x1 (y2 - y3) + 
     x2 (-y1 + y3)))/(-x0 (x3^2 (y1 - y2) (-2 y1 y2 + y0 (y1 + y2)) - 
      2 x2 x3 y1 (y1 - y2) (y0 - y3) + x2^2 y0 (y1 - y3)^2) + 
   x2 x3 (y0 - y1)^2 (-x3 y2 + x2 y3) + 
   x1 (x3^2 y1 (y0 - y2)^2 + 2 x0 x3 (y1 - y2) y2 (y0 - y3) - 
      x0^2 y1 (y2 - y3)^2 - 2 x2 (y1 - y2) (y0 - y3) (x3 y0 + x0 y3) +
       x2^2 (y0 - y3) (y0 (y1 - 2 y3) + y1 y3)) + 
   x0^2 (x2 y2 (y1 - y3)^2 - x3 (y1 - y2) (2 y1 y2 - y1 y3 - y2 y3)) +
    x1^2 (x0 y0 (y2 - y3)^2 - x3 (y0 - y2)^2 y3 - 
      x2 (y0 - y3) (y0 (y2 - 2 y3) + y2 y3)))

so, yeah, not easily computed, but totally something you could compute once when you initialize the filter.

Yes, the following should produce similar result:

$ ffmpeg -i in.ts -vcodec copy -an -f image2 out%4d
$ ffmpeg -i in.mp4 -vcodec copy -vbsf h264_mp4toannexb -an -f image2 out%4d

You basically got it right. (I happened to follow the thread on
ffmpeg-devel, thanks for forwarding it.)

a) An inverse calculation, like in your example given. But that's just
totally over the top, no-one can be expected to be capable of such a
calculation. I tried to figure it out from the code, but couldn't.

> be able to be hardcoded into a different filter (vf_keystone?) I'll
> inquire on ffmpeg-devel if that is possible, to have one filter
> basically just call another filter with different options.

b) What I meant - and you got it totally right on ffmpeg-devel - is to
re-use the code from the perspective filter, because it contains all
the transformations, considerations, and colorspace cruft. Just the
wrong parameters. So the questions regarding "how to re-use a filter's
algorithms/mechanisms without duplicating its code" are spot-on.

That said, I pointed out that the perspective filter is doing peculiar
things with the color edges when using such "negative" parameters. Have
a look at my testsrc example's output. Possibly the perspective filter
was only written with "inside" reference points in mind. The opposite
filter would also need to be able to fill the remaining "empty" space
with some kind of transparency/alpha channel, so that overlaying the
warped frame over another stream is possible. That's basically what the
original poster was looking for, and what makes sense to me from a user
perspective.

I'm happy to try coding, but don't know nearly enough about the libav*
code to cope. ;-)

I happen to be a mathematician, and I've taught courses on projective geometry and perspective. If you know the right question to ask mathematically it's straight forward, but the answer is a mess.

I'm leaning to making it an option to the perspective filter, so you can say how you want the parameters intrepreted, as the locations in the source of the corners of the new video or the locations in the new video of the corners of the source.

I don't know anything about the colorspace stuff but that could presumably be put in. If I understand correctly (a big if), the array pv in the context stores the inverse locations of the new image. If that is outside of the original image, it could just be set to [0,0,0,0] or whatever, but I don't know about color formats or anything.

If you want to handle that, I'll tackle the inverse transformation part.

I see what it is doing, I think it is just interpolating from the data it has. The "peculiar" things you see it doing is probably due to the fact that it might not sample croma at every pixel. I find that if I put a two pixel black frame around the image first it works fine.

I imagine you if you add a two pixel pad of transparent black (0x00000000), it would do what you suggest. I've attached a patch. Apply the patch, recompile and see if 

./ffplay -f lavfi -i testsrc -vf pad="iw+4:ih+4:2:2:0x00000000",perspective=x0=W/4:y0=H/4:x1=3*W/4:y1=H/4:sense=destination

does what you want. If this works, I'll add documentation and submit it.

Thanks Carl, that's pretty useful.

I guess I was not clear enough when I asked I there was a way to do it in
FFMPEG, maybe I'd better say libavformat, I am not using the execution
binaries, I am writing my own application in C using libavformat,
libavcodec and so on. At the moment I am using FFMPEG examples "remuxing.c"
and "demuxing_decoding.c" as a reference to start coding my NALU extractor.
Then, according the Carl Eugen response I assume that I should use video
filters in order to do that, should I read about libavfilter to reproduce
"-vbsf h264_mp4toannexb" behaviour in my C application, or I have some kind
of solution to go throw it having some sort of remuxing in h264 format?

Thank all,
David

Hi everyone,

I installed ffmpeg from git on my machine which runs on Ubuntu14.04.
I followed the instructions given in the below compilation guide.
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

Instead of using the git snapshot as mentioned in the documentation, I did

git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

ffmpeg is installed, but when i typed ffserver at command prompt, it gave
me the error "Could not open the configuration file '/etc/ffserver.conf'
Error reading configuration file '/etc/ffserver.conf': No such file or
directory"

I couldn't find the file /etc but could locate the ffserver.conf in
~/ffmpeg_sources/ffmpeg/doc
I copied it from ~/ffmpeg_sources/ffmpeg/doc to /etc
But I am not sure if this was the right thing to do.

uhm read some manpages

start here
https://www.google.at/search?q=ffserver.conf

you need to configure it for *your needs*
that's why it is a config file

That was definitely NOT the right thing to do. You should never use the root
privileges lightly.

The right thing to do is to read the documentation. FFserver's documentation
is available online:

http://ffmpeg.org/ffserver.html

And you also have a copy of the same documentation in the doc/ directory in
the compilation tree.

The documentation is quite long, but there is a nice table of contents in
the HTML version, and the title "3.3 How do I make it work?" looks
promising.

well, that is what the error message says in your first post

you don't want that file to be installed automatically
or do you wan't to get your config overwritten with updates

Subject: [FFmpeg-user] decimate with dupthresh
Message-ID: <8D1BA05BDCFA2BD-B5C-446AA@webmail-vm102.sysops.aol.com>


Hi there,
would it be possible for someone to explain the dupthresh option for the decimate filter? 

I have a number of different formats with encoded duplicate frames. I cannot remove them with -vsync drop and then manage frame rate.
The duplicate rate varies so I am unable to use the cycle parameter.

The dupthresh option appears to be similar to that used with Mencoder. (I have used  -vf decimate=-0:99999 to remove all images that are exactly the same as the previous).

I would prefer to use ffmpeg and understand the dupthresh option a little better.

Thanks
David

Then please try the mpdecimate filter thought it comes 
from different times and may not be what you want.

Subject: [FFmpeg-user] Problem re-streaming an RTSP stream with ffserver
Message-ID: <CAK-U3HfMOOA8Cmbz1nM7WqL7rhZ+Km0+iSDDzXBXYV8UTNr03Q@mail.gmail.com>

Hi,

Thanks for all the hard work people do for ffmpeg, it's a fantastic tool :).

I am having an issue trying to re-stream an RTSP stream from a camera using
ffserver - any ideas as to the problem would be much appreciated. I am
using the latest git revision of ffmpeg on Ubuntu 14.04.

Scenario: RTSP stream coming from IP camera. The stream can be captured
easily with ffmpeg and output to a file. I am running ffserver (see config
below), and passing the stream to ffserver with ffmpeg (see command lines
below). This part appears to work fine. However, when I try to capture the
rtsp stream from ffserver it gives the following errors:

[h264 @ 0xbc9ac0] decode_slice_header error
[h264 @ 0xbc9ac0] no frame!
[h264 @ 0xbc9ac0] non-existing PPS 0 referenced
    Last message repeated 1 times
[h264 @ 0xbc9ac0] decode_slice_header error
[h264 @ 0xbc9ac0] no frame!
[rtsp @ 0xbc6f80] interrupted
[rtsp @ 0xbc6f80] decoding for stream 0 failed
[rtsp @ 0xbc6f80] Could not find codec parameters for stream 0 (Video:
h264, none(left)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize'
options
rtsp://localhost:8554/test1.rtsp: could not find codec parameters

Here are the details of the setup I am using:

Example ffmpeg command line to capture from camera to a file.
ffmpeg -i rtsp://10.9.9.1:554/axis-media/media.amp -c copy test1.mp4

Does anyone know why I'm not able to do this successfully? I have tried
altering a bunch of settings on the camera, including bring the resolution
right down to reduce the data rate, and adjusting the analyzeduration and
probesize as suggested.

I am able to re-stream an RTSP stream from another source successfully
(rtsp://live.cdn2.streamago.tv/streamago/34961/28964/). Is there likely to
be some sort of incompatibility with the stream from the camera?

Thanks in advance,
-Jonathan.

Hi,

I think you should save the SDP data into a file and then
play/capture/transcode using that file.
ffmpeg -i rtsp://10.9.9.1:554/axis-media/media.amp -c copy
http://localhost:8090/feed1.ffm > test.sdp

I can see some sdp data printed on your log:
SDP:
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Title
c=IN IP4 0.0.0.0
t=0 0
a=tool:libavformat 56.9.101
m=video 0 RTP/AVP 96
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1
a=control:streamid=0

and then:
ffmpeg -loglevel verbose -y -i test.sdp out.mp4

Regards,
Maziar

Thanks for the reply. The ffmpeg command is to continuously stream the
camera's rtsp stream into ffserver. Redirecting the stdout of that process
doesn't seem to do much. That SDP output you saw was from the ffmpeg
process streaming the relayed stream via ffserver.

I may have just answered my own question actually. Adding "AVOptionVideo
flags +global_header" to the stream configuration in ffserver.conf seems to
fix the problem.

Oddly, when using rtsp with udp I get a bunch of missed packets:

[NULL @ 0x24ac900] RTP: missed 1 packets
    Last message repeated 19 times

It does seem to affect the output stream, the video is all distorted. This
camera is on the local network, so there shouldn't be drops like this. The
bitrate is around 8000kbits/s. Specifying "-rtsp_transport tcp" when
streaming from ffserver fixes the output file.

Any idea why "-rtsp_transport tcp" is needed when streaming from ffserver,
but not when streaming directly from the camera?

Regards,
-Jonathan.

Subject: [FFmpeg-user] Send audio to Axis encoder and change http_post header
Message-ID: <205DBBE9F739414F9815C142C7EA61CC0367AA44@exchsvr01.torcrobotics.net>

Hello,

I am trying to send audio data to an Axis encoder using the VAPIX API: http://www.axis.com/files/manuals/vapix_audio_52913_en_1307.pdf

Essentially I send audio to it by pointing something at the address of the encoder:  http://<ip address/ axis-cgi/audio/transmit.cgi, which is an HTTP POST command. I am sending it microphone audio from my computer in an expected format.

The sample header they have in their documentation has the following header:
POST /axis-cgi/audio/transmit.cgi HTTP/1.0
Content-Type: audio/basic
Content-Length: 9999999
Connection: Keep-Alive
Cache-Control: no-cache
Authorization: Basic cm9vdDpwYXNz

When I execute my command, I get this as my header:

Transfer-Encoding: chunked
User-Agent: Lavf/56.7.101
Accept: */*
Connection: close
Host: 192.168.0.90
Icy-MetaData: 1

The "connection: close" is what I think is preventing any data from getting to the encoder as it errors out after one frame.

Full log output is below, any help would be appreciated if I am on the right (or wrong) track here.
Thanks.

Full log output:

Did you test the option "multiple_requests"?

Subject: [FFmpeg-user] Unable to stream H264 via multicast
Message-ID: <20141022180724.4c84c9da@korath.teln.shikadi.net>

Hi all,

I'm having so many problems trying to get this to work I'm desperately
hoping someone can give me some help!

I'm trying to capture video from the Raspberry Pi's internal camera,
which can natively supply hardware-encoded H264 video.  I'd like to
then multicast this over my LAN.  You'd think it would be simple, but
I've been going for five hours now with no luck yet!

I had ffmpeg successfully multicasting over RTP with this:

  ffmpeg -f v4l2 -video_size hd720 -framerate 30 -input_format h264
    -i /dev/video0 -vcodec copy -an -f rtp rtp://224.0.1.2:5001

But any player I tried didn't work except VLC which said it needed an
SDP file.  I tried copying one that apparently ffmpeg printed when it
was run, and VLC accepted it and said it was playing but there was no
video (just the VLC logo showing where the video should be.)

I thought this would be a bit of a hassle having to maintain an SDP
file, so I switched to ffserver instead.  However although ffserver
appears to have an option for broadcasting RTP it doesn't seem to
work?  I'm also not sure where to get the SDP file from, as apparently
you can add ".sdp" onto the end of the URL or something but I just get
a 404 Not Found error doing that.  But weirdly if I run ffserver in
debug mode, the logs it prints says it returns HTTP 200 OK to these
requests even though ffplay says I get 404 or even 503 Service
Unavailable.  So I'm really confused now!

Here is my ffserver config:

HTTPPort 80
RTSPPort 81
<Feed csi.ffm>
        File /tmp/csi.ffm
        FileMaxSize 200K
</Feed>

<Stream csi.h264>
        Feed csi.ffm
        Format rtp
        MulticastAddress 224.0.1.2
        MulticastPort 5001
        MulticastTTL 4
        NoAudio
        Metadata title "CSI Camera"
</Stream>

<Stream csi.asf>
        Feed csi.ffm
        Format asf
        NoAudio
        Metadata title "CSI Camera"
</Stream>

<Stream stat.html>
        Format status
        ACL allow 192.168.0.0 192.168.0.255
</Stream>

I'm running ffmpeg with this:

  ffmpeg -f v4l2 -video_size hd720 -framerate 30 -input_format h264
    -i /dev/video0 -vcodec copy -an http://localhost/csi.ffm

If I try to play rtp://224.0.1.2 I get no data, and I can verify that
no data is being transmitted over the LAN.  If I use mplayer to play
csi.asf I get these errors:

Error while decoding frame!
[h264 @ 0x7ffbde842400]non-existing PPS 0 referenced

I'm not really sure what to do next!  Can anyone offer any suggestions?

Many thanks,
Adam.

I actually figured out the "multiple_requests" option soon after posting my question. In the case of the Axis encoder, I also had to set the "content_type" to "audio/basic" to match their API.
I can confirm that with those two commands it is now working and sending audio to the Axis, which is playing it correctly.

I don't remember why I used FLV, but I remember in my googling that was one of the suggestions. Many of the examples in https://trac.ffmpeg.org/wiki/StreamingGuide also use FLV.

Now I have a periodic popping noise that's occurring at the same time as malformed packets (according to wireshark), but that's probably a question for a different thread.

Thanks,
Mark

Subject: [FFmpeg-user] MP3 enconding bitrate
Message-ID: <5447FD04.80602@gmail.com>

Hi!

I have trouble to get the mp3 encoded right to play on my Volvo 
Infotainment System (Sensus 3.0), so I have contacted the costumer 
support, and they told me that the files are being encoding with frames 
with more than 320Kbps of bitrate.

Since I don't have a tool to debug it, I've tried to see in codec 
statistics in VLC, which for the files I'm showing as example I've seen 
380Kbps near 3:31 mins.

I believe it's a bug on ffmpeg, although I'm not sure, so I'm asking for 
advice here, since encoding with the lame it works like a charm.

I've encoded with this command:

ffmpeg -i 2L38_01_96kHz.flac -codec:a libmp3lame -qscale:a 0 
2L38_01_96kHz.mp3

The file used is from here:
http://www.lindberg.no/hires/test/2L38_01_96kHz.flac

and the mp3 encoded is here:
http://www.datafilehost.com/d/42cf1c8e

and I'm using ffmpeg from rpm-fusion in Fedora 20:

You're using a qscale of 0 which is like saying "use ALL of the bits!"
Raise the q or use -b:a to set a sensible bitrate ilke -b:a 192k

Screenshots of console outputs are unnecessary. The actual content as
text is more useful, is smaller in file size, is easier to copy, and is
searchable.

Two options:

A. Remove --enable-libfaac --enable-nonfree.

B. Install faac. The package is probably named libfaac-dev(el) if you
use a distro that annoyingly splits packages. faac is not recommended
by me since there are better alternatives such as fdkaac. See:
http://trac.ffmpeg.org/wiki/Encode/AAC

OK,

I understand your point, but encoding with lame, instead of ffmpeg 
results in a file which don't pass the 320 Kbps. Also in the 
documentation we have a table of equivalence between ffmpeg and lame 
options:
https://trac.ffmpeg.org/wiki/Encode/MP3

which will induce the users in error because those settings are not 
really equivalent.

Also if I lower the quality setting I'll have the problem anyway...

For reference there is a note in wikipedia in bitrate section:

http://en.wikipedia.org/wiki/MP3

/Non-standard bit rates up to 640 kbit/s can be achieved with the //LAME 
<http://en.wikipedia.org/wiki/LAME>//encoder and the freeformat option, 
although few MP3 players can play those files. According to the ISO 
standard, decoders are only required to be able to decode streams up to 
320 kbit/s//^<http://en.wikipedia.org/wiki/MP3#cite_note-50> //
/

I think I will open a  bug report and try to listen the developers 
opinion on the subject.

Best regards,

Paulo Fidalgo

Message-ID: <CAKkBEKNUeiBhJtmWzbFhmg-Yeni6u-UJU4x6TdaQ5jbFgbeR7A@mail.gmail.com>

Hi all,
This is my first message, nice to meet you all.
We've been using ffmpeg and ffmbc in our small postproduction company for
quite some time. We use it for many tasks.

I remember having used ffmpeg to convert a picture mxf from a DCP to
ProRes. ffmpeg detected the XYZ colorspace fine and converted it OK to YUV,
so the Prores looked gorgeous.
Now I'm trying with another DCP, but ffmpeg fails to see that the mxf is in
XYZ, but sees RGB.

ffmpeg -i INPUT_j2c.mxf -s 1920*1080 -vcodec prores -profile:v 3 -an

Is there any way to force ffmpeg that it interprets the input as XYZ?

Hi,

a newbie here, interested in setting up a server for encoding sport movies (GoPro files) in order to stream them.
Input format will be MPEG4 h.264 in different formats: 1080p, 960p, 720p

Output format (I am still studying it, any suggestions are welcome ^__^) should be:
- MPEG4 h.264 720p @2500 kbit/sec
- MPEG4 h.264 480p @900 kbit/sec


How can I estimate time for encoding? 
Is there any hosting provider offering a good platform for doing it? Or have you any recommendation about what I have to ask?


Thank you for your time and patience, I've searched the list without being able to find any hint!


Best,

F.

Subject: [FFmpeg-user] Automatic encoding of .ts files gives an inexplicable
 delay after muxing
Message-ID: <1414084439652-4667828.post@n4.nabble.com>

Hello,

I'm experiencing a weird problem which I will try to describe in the
following post.

Currently, I'm writing a perl script for automatic encoding of MPEG-TS files
using ffmpeg and x264. I'm having ffmpeg apply video filters like resize,
deinterlace and so on and am then sending the output to x264 via stdout,
which will result in a mkv file. The audio is encoded in a separate ffmpeg
instance to AC3. For testing and checking purposes I'm later muxing the
resulting mkv and ac3 files to form a new mkv file. Both ffmpeg instances
(for video and audio encoding) start at the same position in the .ts file,
or at least so I'm assuming. 

For some weird reason I'm getting an unpredictable audio delay after muxing
(with mkvmerge). It is always a negative value, ranging from -300 ms to
-1000 ms audio delay. The delay is a constant value, so by remuxing the two
output files with some delay added, it'll be sync for the rest of the file.
Yet the delay changes for different files and I can't understand why it does
that and how to fix it. After some googling and reading man pages I tried
skipping the first 10 seconds of both audio and video and checked if it
would fix the problem - unfortunately it didn't, the delay was still there
and still an unpredictable value.

Another thing which I was thinking of trying was to get ffmpeg to encode
video and audio in one instance - however I do not know how to accomplish
that and I'm not even sure if it would fix the problem. ffmpeg would have to
send the video output to stdout (piping to x264) and the audio output to an
ac3 file.

Here's the command lines I've been using: (I should mention the .ts files
are being encoded as they're written to the disk - hence the -re switch;
however "non-live" encoding doesn't fix things)

Video:
ffmpeg -hide_banner -loglevel quiet -re -ss 00:00:10 -i file.ts -vf
"yadif=0:0:0,scale=720x404" -sws_flags lanczos -f yuv4mpegpipe -pix_fmt
yuv420p - | x264_64.exe --stdin y4m --level 3.1 --output output.mkv -

Audio:
ffmpeg -hide_banner -loglevel quiet -re -ss 00:00:10 -i file.ts -map #0:7
-b:a 384k output.ac3

The script is running on a windows box. I've tried google lots of times but
I can't seem to find a solution to this problem. Would you mind giving me a
push into the right direction? I feel like I'm running into a wall here.

Greetings

Your plan is overly general, in this maillist you can get answers for
more exact questions about multimedia data processing. Or say that you
just need to hire a professional to design and implement a system for
you.

As a result, I'm getting the message:

===========================================================================

As far as I understood, each filter creates it's own channel. So FFMPEG can't
handle more than 32 channels (27 MP3 files will produce 54 channels in total).

What is the best way to overcome this limit? I need only 2 channels as output.

Thanks!

Is there a real disadvantage if you do it in two steps?

What's wrong with the following?
$ ffmpeg -i file.ts -vf yadif -vcodec libx264 -acodec ac3 out.mkv
(You have to add the remaining options you need.)

If this doesn't work, please provide the actual 
command line you used together with the 
complete, uncut console output (including banner!!)

Please provide the sample.

For future questions: Please do not cut the console 
output, always provide the first 50 and the last 
50 lines.

Hi Carl,

You can download a short sample here: http://we.tl/KH56sHWuZs

I followed the instructions at

I downloaded the file and use the following command line:

ffmpeg -i 177d8c52-e30d-4b52-8f77-7e7a25e13a79_j2c.mxf -s 1920*1080
-vcodec prores -profile:v 3 -an OUTPUT.mov

The colorspace seems to have been correctly detected and the resulting
MOV file looks fine to me.

The main reason why I didn't try this sooner was because I was worried
ffmpeg wouldn't include the latest version of x264 or it would maybe be too
slow. However after trying out your command line I realised I was wrong and
maybe I was thinking too complex when there was a cleaner and simpler
solution available.

Encoding with my command line produces the following output:

E:\enc>ffmpeg -ss 00:00:10 -i input.ts -vf "framestep=2,scale=720x404"

It seems to need the -map 0:v switch or it won't encode the video stream.
I've tested your command line with multiple files and it seems to work like
a charm. I'll test some more later but for your assistance I offer you a big
virtual cup of coffee and my thanks. However, it's still strange why
separate encoding of video and audio would result in this delay.

Cheerio!

Hi,

Similar to what Andrey replied: Life (and encoding) is more complicated
than this. It seems you're not only a newbie on this list. ;-)

You need to consider: What are your
- target users and devices,
- bandwidth/storage limitation (though you did mention what bandwidth
  you aim at);
- conversion hardware capabilities
and so on. Usually, when choosing codecs and encoding parameters, you
pick e.g. the best of time, space, quality _for your needs_, but you
never get the best of all three!

> How can I estimate time for encoding?

By experimenting. We don't know your hardware or any of the above.

Take some time to look at how encoding works, and play around some. That's
how most people here gathered their experience. Or get consultants. :)

Just a kind hint,
Moritz

It is entirely up to you which version of x264 you 
use when you compile FFmpeg (remember that the 
project FFmpeg only ships source code and only 
supports the source code).

Video encoding is exactly as fast as x264 allows 
(with your compilation options and your runtime 
options), overall speed is of course faster if 
you don't use separate encodings.

I know why you are doing this (and I recommended it often) 
but it makes detection of xyz impossible.

We should probably work on this but I suspect the easiest 
solution is to compile without "--disable-encoder" and 
specify the decoder you want:
$ ffmpeg -vcodec libopenjpeg -i input.mxf
This will use the internal decoder only to decide the 
pix_fmt but will use the (bitexact!) libopenjpeg 
decoder for actual decoding.

Hi!
Mitch, Thanks for taking the time and do the test. This confirms the
problem is on my side.
And Carl Eugen, thanks for knowing what I'm talking about!
I installed ffmpeg one week ago on my mac via homebrew, using this command:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype
--with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis
--with-libvpx --with-opencore-amr --with-openjpeg --with-opus
--with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

So, in theory nothing would be disabled. Should I compile ffmpeg in some
other way?
Thank you

The source files almost always have audio or video delayed from each other. If you encode both video and audio in one step they are kept synchronised.
If you separately encode audio and thereafter video the audio encoding starts -ss 00:00:10 after the first audio part and 
the video encoding starts -ss 00:00:10 after the first video part, so the ?original? delay between video and audio is lost. Everything AFAIK.

Subject: [FFmpeg-user] Questions on loglevel
Message-ID: <819DAAC8-595C-43EC-B5F0-12ACF1B36FB3@gmail.com>


Dear all,

I need to have your help and advice for my problem.
I installed ffmpeg in fedora 16 by using yum command.
After it, I try to run the ffmpeg with option "-loglevel panic" (or others like error, debug, etc).
But, whatever value for the option I put, it does not have any changes.
I would like to use the -loglevel panic or quiet, but it does not work. It always shows in default mode (like info).

Please help me how to solve this problem.
The attached screenshot is the result when I put the option "-loglevel panic"
Please help~~~. I need your advice and helps. 
I appreciate of your helps in advance.

Best Regards,
Eilwoo

Please do not send screenshots to this mailing list.
Instead just post the output of "$ ffmpeg -loglevel panic"

This does not look like a FFmpeg configure command.

Please understand that we don't support any other 
means of installing here than running configure 
and make.

Please don't top-post, Carl Eugen

Subject: [FFmpeg-user] trouble with serving rtsp
Message-ID: <CAEsx0Y9hYgHR2g44QP7M0ig=8Wpx9KaWpBYccpe4Tc25DzLWBA@mail.gmail.com>

Hello All,

 I'm trying to serve an mp4 video over rtsp but for some reason ffplay
will not play the video stream. I am at a loss about what to do next.
Please advise on how I can view the stream via rtsp.

Please ask them to explain which frame has >320kb, I 
don't think it's true, see below.

I played the encoded file you uploaded with vlc, 
it does not show a bitrate of >320 here at any 
time.

I then analyzed the file you uploaded:
$ ffmpeg -i outff.mp3 -acodec copy -f image2 -map 0 out%5d
The largest mp3 frame in your encoded file is 960 bytes 
which corresponds to 320kb/s.
Maybe you should test the following to verify:
$ lame -b 320 input.wav out320.mp3
$ lame -b 256 input.wav out256.mp3
Do both files play in your car?
Or only the second?

lame documentation states that the default for lame's 
-q option is 5 but if you use -V, the default is lower 
(4 or smaller for your input sample).
This may be a bug, either in the documentation of 
FFmpeg (because it states that FFmpeg's option -q 
corresponds to -V which is mostly does but not exactly) 
or because FFmpeg sets lame's -q to 5 if you don't 
specify anything else.

Please test with -compression_level 4, this should 
produce output files more similar with lame.

Thanks for the links, but: *Can't I do that from ffmpeg?*

Thing is, I want to script switching of streams, and I want to have
the option to later use another server for broadcasting.

i have also not yet found a way to loop video files.. but you can loop an image (or image sequence)

i use this for some of my radio stations? ( -re -loop 1 -i /path/to/image.jpg )

ffmpeg -i http://shoutcasthost.com:8000 -re -loop 1 -i /path/to/image.jpg -c:a libfdk_aac -b:a 192k -c:v h264 -preset ultrafast -pix_fmt yuvj420p -bsf h264_mp4toannexb -f mpegts udp://127.0.0.1:10000?pkt_size=1316

Thanks! I modified that a little, and now it works for DASH
broadcasting with Wowza:

    $ ffmpeg -re -loop 1 -i image.jpg -c:v h264 -preset ultrafast \
    -pix_fmt yuvj420p -bsf aac_adtstoasc -f flv \

Unless I am mistaken (I have only done this with audio, icecast, etc.), your 
problem is that any break in the stream will disconnect clients, or at least 
inconvenience them rather a bit.

Thus, the solution has to be server side, in which case you need a 
fallback stream to fill the gaps.  Even if only used briefly, if your server 
supports it, you fall back to a holding pattern stream (company logo looped or 
something), and then stream in your new content from the script.  Even that will 
make discontinuities, and I have no idea if Wowza or anything else supports it.
Unless your server supports holding client connections open during a disconnect-reconnect cycle of the source client, which is what will happen here.

One possible ffmpeg-only solution comes to mind.  This is a bit out there.

Feed your ffmpeg source client from a segmented MpegTS stream.  In other words, 
feed it from HLS generated locally.

Ffmpeg instance one generates a segmented stream for five minutes, then exits.

Meanwhile, ffmpeg two (source client) takes that stream and sends it to 
Wowza/whatever  server.

When ffmpeg one stops, with maybe eight seconds left in the last segment 
(assuming ffmpeg two is keeping up, and 10 second segments):
Ffmpeg three starts, generating segments with numbering starting where ffmpeg 
one left off (you'll likely need to `tail` the .m3u8 file to figure out where to 
start).

I believe that ffmpeg two, which is taking the segments and compiling them to 
send as a stream to the server, will not know the difference between one origin 
stream and another, since their all just segments as far as it's concerned.

Not having tried this, my only worry at the moment is catch-up.  Every time 
you do this, the source client (ffmpeg two in the above plan) will get a little 
closer to falling off the end of your segments.

Good luck.

The entirety of this email is speculative, and could be punctured with a dull pin.

Thanks Luke! Hm, I thought it was standard feature. But being not, I
guess I'll first look at Wowza which seems to be scriptable with
ActionScript. Fortunately, I've used ActionScript before: Many years
ago, I wrote a streaming video player, based on AMS.

Anyhow, there must be a smooth solution.  l just can't believe that
it's not possible to run something akin to a TV station on the
Internet.

Of ffmpeg?  The ability to add to the list of sources after the process has 
started?  I highly doubt it.
I have never seen a feature like that in ffmpeg described.  Maybe you need the 
ability to read a list of sources from STDIN on an as-needed basis?

But don't take my word for it Felix, I could still be quite wrong.

The requirement for continuous video is how I *think* it works, and that weird 
segmenting idea is the only way I can think of using only ffmpeg to do it.

I would imagine that if there is another way to have ffmpeg stream from a file, 
and add to that file dynamically, you could accomplish the same thing, but I 
still think you would need a headerless format (I.E. MPEGTS) to make it work.

I am no authority on this, I just wanted to present a possible answer that 
nobody else mentioned.

If I recall, Wowza has a JAVA API as well, if you want to get really serious 
about it.  But your problem hasn't changed, you just moved it from the source to 
the server.  It may be that Wowza already has a connection keeping feature for 
this.  Present it on their list and see what you get.

I'm sure you can, as long as you can avoid interrupting the stream.  Which was 
my whole point.  You would seem to need a constant stream, with ability to 
switch sources in and out of it on the fly.  But there always has to be 
something streaming, even in the short gap between sources.  Someone correct me 
if I'm wrong please.

to sum it all up im generating 2 spectrograms and 2 waveforms using the audio from a shoutcast server. each one plays for 24 hours before switching to the next one in the list. if a stream is published with the name djstream, it will immediately switch to that content? once djstream is finished it goes back to the schedule again, rotating once every 24 hours to the next stream? the single

i believe the app type has to be ?live? for most of this stuff to work, and i dont think you can switch to a stream published to a different app.

ok enough wowza on the ffmpeg list.. let me know if you have any q?s, etc

cheers!

I?ve been thinking: For gapless playback, it?s probably best to have two
video streams running, and then switch between these with some kind of
mixer. As I?ve just found out, software implementations of mixers for
video are called [Software vision mixers][1].

When homebrew builds ffmpeg with openjpeg it disables jpeg2000 (see this commit: https://github.com/Homebrew/homebrew/commit/66a7aa83fdba702a7981744a3db564fc3b953297). This was done because as the commit note says the jpeg2000 encoder/decoder "mostly doesn't work".

To build an ffmpeg as Carl suggests, run `brew edit ffmpeg`, and delete this line `args << "--disable-decoder=jpeg2000"`.

Message-ID: <CABUACgbTeCcFhASczuFGg5bHqCcDzqU0-51tOJPzMvUWRwB=ew@mail.gmail.com>

Hi, i have this command.

I want to generate different times for my ts files.

My command:

ffmpeg -y -i rod.mp4 -force_key_frames
2,2,3,3,4,4,4,4,4,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,9
-codec:v libx264 -r 25 -g 25 -codec:a libfdk_aac -f stream_segment
-segment_times
2,2,3,3,4,4,4,4,4,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,5,9
-segment_format mpegts


But this command generate ts files with wrong durations. The espected
result is:

00.ts -> 2 seconds
01.ts -> 2 seconds
02.ts -> 3 seconds
03.ts -> 3 seconds
.....
.....
.....
Last ts file is 9 seconds.

The sum of all this number is the duration of the video.

Thanks

Message-ID: <7aa8dce4.b82f.1493c2e880e.Coremail.jingshaoqi@163.com>

HI?

I have been confused several days, how I convert a video (H265 format,MkV)  to H265 ts file, my command line as follow: 

ffmpeg -y -i tos-4096x1720-tiles.mkv -r 24 -b:v 2300000 -c:v libx265 -x265-params crf=26:psy-rd=1:subme=3:merange=32:bframes=2:b-adapt=1:rc-lookahead=10:keyint=200:min-keyint=50:open-gop=1:bitrate=2000:threads=64 -acodec copy tos1003.ts 

this command convert ts file very slow and no video information, only having audio information.

Two pictures are  tos-4096x1720-tiles.mkv  basic information, parsed by MediaInfo. 

Command line is correct? 

Yours sincerely

Subject: [FFmpeg-user] ffserver streaming H.264 from Logitech C920
Message-ID: <CA+gB0yjRYVgs=X8OUT_P4nu1YGXf2CVdDj4APkGXTkDKjSdJoQ@mail.gmail.com>

I'm having some trouble trying to implement a web live stream from my
Logitech C920 webcam w/ H.264 encoding using ffmpeg/ffserver.

Here is the configuration file I'm using for the ffserver:

# Port on which the server is listening. You must select a different
# port from your standard HTTP web server if it is running on the same
# computer.
Port 8090

# Address on which the server is bound. Only useful if you have
# several network interfaces.
BindAddress 0.0.0.0

# Number of simultaneous HTTP connections that can be handled. It has
# to be defined *before* the MaxClients parameter, since it defines the
# MaxClients maximum limit.
MaxHTTPConnections 2000

# Number of simultaneous requests that can be handled. Since FFServer
# is very fast, it is more likely that you will want to leave this high
# and use MaxBandwidth, below.
MaxClients 1000

# This the maximum amount of kbit/sec that you are prepared to
# consume when streaming to clients.
MaxBandwidth 1000

# Access log file (uses standard Apache log file format)
# '-' is the standard output.
CustomLog -

# and/or audio sequence coming from an ffmpeg encoder or another
# ffserver. This sequence may be encoded simultaneously with several
# codecs at several resolutions.

<Feed feed.ffm>

# You must use 'ffmpeg' to send a live feed to ffserver. In this
# example, you can type:
#

File /tmp/feed.ffm
FileMaxSize 100M

# You could specify
# ReadOnlyFile /saved/specialvideo.ffm
# This marks the file as readonly and it will not be deleted or updated.

# Only allow connections from localhost to the feed.

</Feed>


##################################################################
# Now you can define each stream which will be generated from the

# request containing this filename.

And here is the command I'm issuing through the command line and the
respective output:

And I can't watch the stream on the web browser side either.

Could someone give me an hint on this?

You should provide timing list, rather than durations - 0,2,4,7,10.....

"-re" should be unneeded, "-bsf aac_adtstoasc" makes

In the meantime I discovered [FreeJ][1], which should be able to do
what I want. However, it's limited to Ogg Theora, so would require
live reencoding before sending the stream to the broadcasting
software.

Also, I asked on one of the GStreamer mailing lists if that tool could
be a solution. There actually is a videomixer plugin for GStreamer.

After making another test with lame and ffmpeg and using the same input 
file, every file from lame works although none of ffmpeg files have worked.

lame -b 256 2L38_01_96kHz.wav 2L38_01_96kHz-lame-256.mp3
lame -V 0 2L38_01_96kHz.wav 2L38_01_96kHz-lame-V0.mp3
lame -V 1 2L38_01_96kHz.wav 2L38_01_96kHz-lame-V1.mp3
ffmpeg -i 2L38_01_96kHz.wav -codec:a libmp3lame -qscale:a 0 
2L38_01_96kHz-ffmpeg-qa-0.mp3
ffmpeg -i 2L38_01_96kHz.wav -codec:a libmp3lame -qscale:a 1 
2L38_01_96kHz-ffmpeg-qa-1.mp3
ffmpeg -i 2L38_01_96kHz.wav -codec:a libmp3lame -qscale:a 2 
2L38_01_96kHz-ffmpeg-qa-2.mp3
ffmpeg -i 2L38_01_96kHz.wav -codec:a libmp3lame -qscale:a 3 
2L38_01_96kHz-ffmpeg-qa-3.mp3
ffmpeg -i 2L38_01_96kHz.wav -codec:a libmp3lame -qscale:a 4 
2L38_01_96kHz-ffmpeg-qa-4.mp3

Now I don't have any clue of what is going on... and what is causing 
this malfunction.

Also I've found that Amarok, the package which leads me to this 
behaviour is also using 4 as audio quality value.

So most things work alright now. But I'd like to have the "Encoding Settings"
header back in my mkv files like the standalone x264 adds them - ffmpeg's
muxer doesn't seem to do that. What would I have to do to fix that? I've
tried ffmpeg's -metadata option, but it doesn't work like I want it to.

Subject: [FFmpeg-user] Mathematically lossless MotionJPEG2000 encoding
	possible?
Message-ID: <544E90E1.9030204@gmail.com>

Hello

I am testing the jpeg2000 encoder (libopenjpeg) but I always get a 
damaged image (Colorshifting, Color flickering, etc..)
Generally asked: is it possible to encode to Motion JPEG2000 with 
following pixel formats in ffmpeg?

yuv420p
yuv411p
yuv422p
yuv422p10le
yuv444p10le

If yes, how is the correct encoding syntax?
My used syntax:

ffmpeg -i <inputfile> -vcodec libopenjpeg -pix_fmt yuv422p -an <outputfile>

I am shure that this syntax is not correct (not enough in defining the 
correct encoding params), furthermore I made no setting for LOSSLESS 
encoding mode.
Therefore I just need a HOW TO for jpeg2000 lossless encoding.

Addionally: which container formats are supported within ffmpeg for 
MotionJPEG2000?

Best Regards
Christoph Gerstbauer

-fpicfPIC must be a joke

Is this something ffmpeg would need new code to support, or does it already know how to deal with (say) Dirac in MXF?

Please always provide an actual command line (no 
variables) and the complete, uncut console 
output if you ask for support here.

Why?
I don't think so.

Lossless is the default for libopenjpeg iirc.

avi (including mkv), mov, mxf, nut

Finally, please note that ffv1 is faster than 
libopenjpeg, compresses better and should make 
significantly less trouble than the so-called 
"professional" solutions you are being offered.

The file created by lame works, although the ffmpeg don't.
If there's something I can do to further investigate please let me know.

Do you mean "ffv1 is faster/compresses better than libopenjpeg" or
"ffv1 is faster/compresses better than motionJPEG2000 generally"?

Your encoding looks okay to me, but what process are you using to decode the resulting jpeg2000 file where you notice to color issues. Could you test playback with libopenjpeg:
ffplay -vcodec libopenjpeg -i C:\TESTS\8bit_jpeg2000_yuv422p.avi

Hello David,

using "ffplay -vcodec libopenjpeg -i ..." works.
So I have to force decoding with libopenjpeg to get an correct output.

Compression:
As I see: ffv1 compressed (if not using slices) a little bit better than jpeg2000.
But ffv1 is much more faster than jpeg2000.
Can you explain me why jpeg 2000 is so extremely slow and needs much more CPU load than ffv1?
Where is the difference here? Both are wavelet transformation codecs, not?

I am very disappointed that jpeg2000 is a "standard" and ffv1 is not :/
FFv1 would get much more acceptance in the "professional" video world if it would be.

The reason why i want to test jpeg2000:
We are always using ffv1 but we sometimes we get "contrary wind" from the professional video world against ffv1 (like: "jpeg2000 is THE lossless codec...."). So we want to show compression rate7speed comparisons for 10bit pixel formats and above, to open their eyes.

Another option is to use --disable-decoder=jpeg2000 when configuring to prevent its use. In most encoding or decoding scenarios ffmpeg's default jpeg2000 encoder/decoder (named ?jpeg2000?) is broken.

Others could explain this much better than I. Note that ffmpeg can recently do some threading with libopenjpeg encoding so current speeds though slow are at least double what they were last year.

I think this subject has been on the list before (to further standardize ffv1), maybe time to revive that thread.

> We are always using ffv1 but we sometimes we get "contrary wind" from the professional video world against ffv1 (like: "jpeg2000 is THE lossless codec...."). So we want to show compression rate7speed comparisons for 10bit pixel formats and above, to open their eyes.

It sounds like there are two contentions:
1) that there should only be one lossless codec in use professionally
2) that jpeg2000 should be that one lossless codec

If contention 1 is invalidated than contention 2 is not so meaningful. I don?t really see a good argument for a singular lossless codec. Archives are filled with many different film gauges, dozens of video tape formats, and huge varieties of digital media specifications and the variety is created because of the need to meet competing priorities (fast or slow, large or small, long term or temporary, open or closed). Because of the nature of lossless codecs and ffmpeg?s support of frame-level checksums it is feasible to encode around and around from uncompressed to jpeg2000 to huffyuv to ffv1 without loss (as long as significant characteristics are maintained). Either way any organization utilizing lossless codecs for preservation (or I suppose this goes for any codec) should be able to trust and ensure that they can maintain their ability to decode and assess that codec. If that maintenance becomes tenuous, when a codec becomes an obsolescence risk, then there is a need to transcode losslessly to preserve in a safer environment. In my opinion ffmpeg provides the tools needed to maintain, assess, transcode, and wrangle collections of either ffv1 or jpeg2000, but I can understand that for some they may have a more supportive community based on one codec or the other based on their professional network, still if considering the factors of speed, software support, and features I think you?ve already seen the difference.

One further note for ffv1 for preservation is its self-descriptiveness. FFv1 version 3 maintains information about field dominance, sample aspect ratio, and pixel format within the codec whereas jpeg2000 is moreso dependent on standards like SMPTE422M and the container. FFv1 version 3 also mandates embedded crc values per frame, which is a huge plus for long term preservation.

Hello David,

you said "FFv1 version 3 maintains information about field dominance".
How can I set the field order when I encode to ffv1? With "-top 1"?
And can I read the field order with the "show_frames" syntax or otherwise?

Subject: [FFmpeg-user] FieldOrder detection with an timestamp list (time

Message-ID: <544EB77A.7070805@gmail.com>

Hello

ffmpeg has a very good field detection algorythm:

ffmpeg -i <INPUT_FILE> -vf idet -f rawvideo -y NUL

Output:
[Parsed_idet_0 @ 003ea220] Single frame detection: TFF:0 BFF:153 
Progressive:0 Undetermined:0
[Parsed_idet_0 @ 003ea220] Multi frame detection: TFF:0 BFF:153 
Progressive:0 Undetermined:0

Is it possible to extract an timestamp list where you can see on which 
timeposition in the file the field order is changing?

Like this:
00:00:00.000 - 00:00:23.040  TFF
00:00:23.080 - 00:01:00.000  BFF
00:01:00.040 - 00:02:00.000  Progressive

Sometimes material is made where field orders are switching, so it would 
be very helpful to find the exact time position where the field order 
changes.

It seems you created a raw audio file. ffmpeg cannot detect it as such,
because it is raw, i.e. it has no headers or such to indicate its
format. You need to tell ffmpeg via the input file parameters (before
"-i" what type of file to expect. In your case, that should probably be
"-f s16le":

./ffmpeg -f s16le -i ~/file.raw -acodec mlp -b:a 18m -r 29.97 -strict unofficial -sample_fmt s16 ~/final.mlp

(Depending on what sort of file ~/file.raw actually is.)

I, for one, have been wanting a format like this ever since I started
working in this industry and so do quite some of my colleagues.
Internally we are discussing to at least consider the format for archiving.
As for implementation, the goal of the project is to make a solid library
that can handle both the streams and container.
So most of the stuff will be handled by the library itself. I'll be making
an effort to contribute to the project as well both for learning purposes
and to have someone within our company with deep knowledge of the format.

And you have shown convincingly that there is a better alternative 
to one existing jpeg2000 implementation. It will be no problem to 
write a faster one if you have the time (or the money), I am not sure 
if compression will be better than with current libopenjpeg.

Note that the issues with jpeg2000 are of course nothing against the

How much (approx) would it cost to write a faster jpeg2000 encoder for 
ffmpeg?

The most solutions which are using JPEG2000 are encoding in lossy 
compression mode, as far as I know.
Additionally, I spoek last week with a very professional video guy, and 
he said to me how he checks the "losslessness" of jpeg2000.
He makes a difference picture of the original source and the encoded 
jpeg2000 -> and checks this just VISUALLY. (o.O)
He does not make frame md5s. So his (mathemtically) lossless checks are 
only visually checks.

And yes, I know that there are so mich implementations. Like Samma Solo 
(Front Porch) or OpenCube etc...
The most solutions which are using JPEG2000 are anyhow encoding in lossy 
compression mode, as far as I know.

Yesterday I tested to extract the original source from a libopenjpeg 
encoded file, and it worked (check was done with framemd5 checksums).
But i need to force ffmpeg to use the libopenjpeg decoder.
If I give the jpeg2000 MXF file (libopenjpeg) as source into a CARBON 
CODER, the picture looks exactly like the same I see in ffplay when I 
DONT use the libopenjpeg decoder. Officially Carbon Coder is able to 
READ jpeg2000.... but not to read correctly?

I was hoping you would understand that this money is (from your point 
of view) wasted.
Since this would be a very welcome patch to FFmpeg, please ask Michael 
or Kamil Nowosad. Note that the decoder should be fixed at the same time.

This seems unlikely to me but I am definitely no j2k expert.

Of course.
Sorry if you believe that this is not sufficiently documented, this 
is one of the very indirect (but still bad) consequences of the fork.

(Did you already guess why Carbon Coder produces the same output as ffplay?)

Could you please send the Carbon Coder EULA either to this mailing list or 
to me personally? This would be *very* welcome!

I believe "professional(ly)" originally means that he is doing it as a
profession, i.e. to earn his livelihood. It doesn't have to mean he
does it well. ;-)

As in "amateur sports" vs. "professional sports".

Just to make sure:
All contributions (code, documentation, reproducible bug 
reports and financial contributions) for FFmpeg are very 
welcome (and needed)!

To the best of my knowledge, FFmpeg supports most of 
what this project wants to achieve, the remaining 
features should not take 6 months to implement.
(And from a quick look, the missing features are only 
missing because nobody specified them yet.)

Hmm.
Is the problem related at all to "-q:0" or is it also reproducible 
if you specify a bitrate (or neither bitrate nor quality)?

You could ask Volvo again (as said, the bitrate is not >320 for any frame) 
but I wonder now if you shouldn't just use -write_xing 0 or -id3v2_version 3.

Thats why I made this smilie:

(o.O)

I meaned that in the international video world, this "professional" 
video guy is a very important person (eminently respectable in some 
video issues).
I was wondering myself how he could get this status, when he is just 
checking visually his content.
I can never trust my eyes, but I can always trust a framemd5 (numbers 
dont lie).
He didnt know that the possibility to check via framemd5s even exists...

Anyhow, how can a set the LOSSY encoding in libopenjpeg? via "-b:v" or "-q"?
I want to know all encoding/decoding paramaters of the libopenjpeg codec 
or also j2k (if this is still implemented codec, even if it is 
experimentally)

For reference, here is one relevant part:

It seems this is an FAQ. Most answers hint that mp4 is not a suitable
format, despite "flags +global_header".

If you replace the above config with flv:
<Stream test.flv>
   Feed feed1.ffm
   Format flv
[...]

and access the appropriate URL with ffplay
(http://localhost:8090/test.flv), it works fine (for me).

Thank you for your help Moritz, I tried your suggestion and I can say it
works.

I'm now trying to implement the same thing but using webm streaming, with
the same configuration, just replacing the format and VideoCodec:

*<Stream test.webm>              # Output stream URL definition*
*   Feed feed1.ffm              # Feed from which to receive video*
*   Format webm*

*   # Audio settings*
*   NoAudio          *

*   VideoCodec libvpx*
*   VideoSize 1280x720           *
*   VideoFrameRate 25          *
*   AVOptionVideo flags +global_header  *
*   AVOptionVideo cpu-used 0*
*   AVOptionVideo qmin 10*
*   AVOptionVideo qmax 42*
*   AVOptionVideo quality good*
*   AVOptionVideo me_range 16*

*   AVOptionAudio flags +global_header*
*   PreRoll 15*
*   StartSendOnKey*
*   VideoBitRate 1M*
*</Stream>*

but when i try to run it with *ffmpeg -f v4l2 -input_format rawvideo
-pixel_format yuyv422 -framerate 25 -video_size 1280x720 -i /dev/video0
http://localhost:8090/feed1.ffm <http://localhost:8090/feed1.ffm>*, i get

You're probably not encoding to webm. You need to add something like
-c:v libvpx
to your ffmpeg command line. But I'm just guessing, I can't test since
I don't have libvpx.

But should't ffserver configuration file provide the encoding options,
namely *VideoCodec *libvpx?

With ffmpeg command I'm just feeding the raw video stream...

Subject: [FFmpeg-user] Images and Lengths of Time to Generate Video
Message-ID: <CAESeFGtn47_UTciY+1V-Lbcpvp9HXV+d6uex7j6u3zAkDYwOpQ@mail.gmail.com>

Hello ffmpeg-users,


I am currently working on a project where I would like to take a series of
images and create a video, however, I would like the images to be displayed
for a certain, but different amount of time.

For example, I have a series of 3 images, image1, image2, and image3. I
would like image1 to be displayed for 3 seconds, image2 for 9 seconds and
image3 for 4 seconds. Ideally, I could take care of this problem using
timestamps (since I generate these files in the order and the approximate
time frame they need to be rendered), but am not sure that is possible.


Additionally, I know that I could, in a script, generate a loop video of
each of the images separately, and then concatenate those videos in order
to get the desired output, but I didn't know if it was possible to do this
in a different way, with ffmpeg.


Any help would be much appreciated!


Ryan

hi,

using the below line,

./ffmpeg -f s16le -i ~/file.raw -acodec mlp -b:a 18m -r 29.97 -strict
unofficial -sample_fmt s16 ~/final.mlp

Using a human eye and a computer screen to verify losslessness at this scale doesn?t make sense for a number of reasons. Both the original video and the lossless version would have been converted to RGB and 8 bit to show on a computer screen so any details in higher bit depth content or lost in the colorspace conversion would not be noticeable. If you presume that the video is one hours of NTSC SD video that 720x486 times 29.97 frames/second times 3600 seconds per hour or 37,753,568,640 pixels that represent values from multiple planes. Despite how 'professional' someone may be I don?t think it is feasible or sane for a human to visualize determine what sample value is represented per pixel in a computer screen representation of a video and if it exactly correlates to a related pixel in another video. Even if they use intensive sampling to accomplish this it?s likely a visual check would miss single frame discrepancies like this one: https://twitter.com/dericed/status/482195897456275457.

Not too hard to conceive of changing DECODER->ENCODER or DECODER->DISPLAY to DECODER->CHECKSUM.

IIRC the libopenjpeg encoder/decoder in ffmpeg only supports lossless encoding.

ffmpeg -h encoder=libopenjpeg

You can do that with the concat demuxer:

file a.jpg
duration 5
file b.jpg
duration 3

Note that the last frame's duration may not be preserved by the rest of the
chain, especially if you use -vf fps=X:round=down to achieve a common frame
rate. You can work around that using a final last frame:

file b.jpg
duration 2.96
file b.jpg
duration 0.04

Hi greeshma,
you're writing this MLP encoder, right?

You have hit a segmentation fault. Most likely in your own code, but
that's not known at this point. If you have modified the code, and
can't reproduce this with "vanilla" ffmpeg source code, you'll have to
debug by yourself.

If you run ./ffmpeg_g instead, you should get a proper stacktrace.

Otherwise, use gdb and possibly valgrind to get to the root of the
problem. Short intros here:

If you don't know how to debug _your own_ code, I can't help you much
further. But a look at a proper stack trace and some general gdb
knowledge will usually help you out.

Set -compression_level to anything >0.
But please remember ticket #3754. you have to use libopenjpeg 1.3 if you 
really want compression.

The concat demuxer did the trick.

Thank you, Nicolas!

Subject: [FFmpeg-user] ffmpeg4android and missing math functions
Message-ID: <CACSc5E1EiT6_XSD0zeDpwNdLz4Vr=3W=BEUMwW+BCxv31jZkTg@mail.gmail.com>

This thread came to my attention today:

http://ffmpeg.org/pipermail/ffmpeg-user/2014-July/022377.html

Although the problem is solved, I want to point to the root cause, which I
reported long time ago, here:

https://code.google.com/p/android/issues/detail?id=38423

Because Android build system is so different than "regular" ./configure;
make; it introduces all kinds of ugly porting problems, which may be
resolved only by all kind of ugly hacks (which You may see in
ffmpeg4android makefiles), especially when You step away from default
architecture.

So, there is libc in NDK which You can download from android homepage,
there is libc in NDK which is embedded in android source code tree, and
there is bionic, Android's version of libc. And the problem is - although
highly compatible, THEY ARE NOT THE SAME. Same may apply for other
libraries. configure/make is not aware of bionic, or any other library
present in Android source code tree, it is aware of libc and libraries
installed in NDK sysroot (which is minimal), and in the end Your software
needs to be linked and run against bionic, and libraries in Android source
code tree. This is a source of horrendous problems when trying to port
something to Android. E.g. in order to enable libx264, the library needs to
be installed in NDK sysroot, so it may be found during configure phase, but
in order to use Android build system to build FFmpeg with libx264 enabled,
libx264 needs to be ported, compiled, and its binaries in
out/target/product/.../wherever folder.

The horror increases when You involve C++.

Subject: [FFmpeg-user] Combining two audio feeds from live rtsp sources into
 stereo is delayed
Message-ID: <205DBBE9F739414F9815C142C7EA61CC036811D4@exchsvr01.torcrobotics.net>

Hello,

I have two live video feeds with audio coming in over rtsp. I would like to take each audio feed that also comes in, which is in mono, and combine them both into a true stereo feed so that one feed plays in one ear and one feed plays in the other simultaneously.

When I use amerge like described in: https://trac.ffmpeg.org/wiki/AudioChannelManipulation#a2monostereo, I get a delay between the two sides. It does not occur if I use two mono files as inputs instead of two live feeds. If I switch the order in of 0 and 1 in -filter_complex "[0:a][1:a]amerge[aout]" it changes which one gets delayed, but the delay is still there. If I open the two video feeds using VLC, both feeds come in at the same time, so there's no delay on the feed side.

Command used:
ffmpeg -y -i "rtsp://172.24.0.31:554/axis-media/media.amp?camera=1" -i "rtsp://172.24.0.32:554/axis-media/media.amp?camera=1" -filter_complex "[0:a][1:a]amerge[aout]" -map "[aout]" output.m4a -report

Thanks,
Mark

There are similar problems compiling FFMPEG on MIPS/UCLibc

See:
https://ffmpeg.org/pipermail/ffmpeg-user/2014-August/023120.html

I have now got the same errors by two completely different methods ...
	1)	Compiling with the native GCC on the target device
	2)	Compiling with a cross-toolchain
... and have come to the conclusion that the problem is fundamental to
FFMPEG, in that it somehow is not configured correctly for UCLibc (despite
the title of my original thread, I now think that most probably MIPS is
irrelevant, and the problem is really UCLibc.

Message-ID: <CABUACgb1+7L-Ldc8jEf5oyNyQaP+c3LzHXpf-Ogd_kBADCBtiw@mail.gmail.com>

Hi,

I have some working videos with different encoding durations

ffmpeg  -y -i http://<URL>/File.mp4 -c:v libx264 -f mp4 bla.mp4 (encode
fast)
ffmpeg  -y -i http://<URL>/File.avi -c:v libx264 -f mp4 bla.mp4 (encode
fast)
ffmpeg  -y -i http://<URL>/File.mov -c:v libx264 -f mp4 bla.mp4 (very slow
encode, and the quicktime format do lots of 206 HTTP request to my server
to process the video).

Do you know any solution to process the mov videos from url faster?

Complete, uncut console output missing.
Did you run qt-faststart on File.mov?

If no wallclock is shown as start time here, I

Subject: [FFmpeg-user] FFMPEG : Redirecting Matroska muxed data to socket
Message-ID: <54508245.6030109@gmail.com>

Hi all,

I am using FFMPEG library to mux H.264 and AAC frames to Matroska (.mkv) 
file. I can do that both using command line and C program.

Now, instead of writing the muxed matroska data into file I want to 
write these muxed data directly on to socket or pipe. My actual goal is 
to write a C program that send muxed data to socket and server will 
receive this muxed data.

I tried using protocol tcp. They are working with the matroska format.
So, My C program is able to send muxed data successfully over socket and 
server is able to receive this muxed data.

But when I apply ffprobe command over the received file, I am getting 
duration and bitrate field N/A. and when I tried to play this file with 
vlc i am unable to seek the file and getting garbage duration.

Below the output of the ffprobe.

As You can see Duration and Bitrate field shows N/A. However I am 
getting correct startTime.

Any help or advice? Thank you in advance.

If you do so, FFmpeg will be unable to update the 
duration field in the header of the output file.
(The field is at the beginning of the file.)
You have to decide if you want the duration field 
to be written (and use file output or another 
output that allows seeking) or if you need pipe 
output (so the duration cannot be written).

Please understand that cross-posting is considered 
rude everywhere afaik and that posting user 
questions on the development mailing list is not 
welcome.

Just to make sure:
With the toolchain in question, the headers and the actual 
library didn't agree whether sincos() is available or not.
Maybe I am too harsh, but I still believe this defines a 
broken toolchain. A simple workaround was found.
If this is really the typical situation when building for 
Android, we can add the check to configure (so that the 
workaround would not be necessary) but fate builds for 
Android and this problem was only reported once so I 
assumed a local breakage / a broken installation.

The relevant issue here (on this mailing list) is - as the 
link above shows - that only unpatched current FFmpeg is 
supported here and that I (still) believe it allows to 
build for Android.

Do you want to discuss one or both of them?

I asked for the output of "grep HAVE_FMINF config.h" 
but didn't find it in your long answer.

Note that we want to support such configurations 
as yours but without your help it is going to 
be difficult.

One more thing: The compiler you used was gcc 4.0.4.
This is very old and if a newer compiler is 
available, please use it.
(Note that 4.2 is completely broken though.)

If no wallclock is shown as start time here, I don't think this can work at all.

Ive been playing with the code and have a little test project I want to try, a mosaic generator.

Now Ive been looking through the examples code and tried a few but none seem to be able to stream out over multicast.

Has anybody got code/knows of example code which shows how to setup a stream which will output a mpegts to a udp multicast address.

I think i have most of the other code from the examples.

The mosaic will work this way

X streams in, running in threads which will send each I frame to the encoding thread, this thread will resize the incoming frame to the correct size and then put it in the correct place on the output frame.

The output frame will then be encoded and streamed out, this is the part that i cannot find any code for.

Ive tried ffmpeg for this but when dealing with 9 streams (3x3) the startup time is way to long and it does not auto restart a broken stream, which Im trying to overcome.

Any help/involvment would be gratefully received

Subject: [FFmpeg-user] lying about metadata output?
Message-ID: <20141029140723.GB19381@sunshine.barsnick.net>

Hi,

I just encountered a situation where there was a mismatch between what
ffmpeg claimed to put into its output metadata, and what was actually
put into the resulting file.

Why do I bother? It's confusing, and also caused me to try to
manipulate the metadata further, although ffmpeg was already doing the
right thing. I had grabbed an m4a file from YouTube, but it has the
metadata "major_brand : dash", which AtomicParsley refuses to process.
So I though I'd use ffmpeg instead to add artist and title metadata,
and at the same time change the major_brand. In the "conversion"
(remuxing) process, ffmpeg claims to retain this metadata, but in
reality, changes major_brand and compatible_brands (which is good).

So just out of interest: Does the muxer change metadata _after_ what is
reported by the section "Output #0, ipod, [...] Metadata:"? I thought
"Output #0" was the muxer (i.e. container), "Stream #0" was the encoder
(i.e. codec).

Here are the two commands, the first command remuxing the file and
reporting unchanged metadata, the second command inspecting the remuxed
file and reporting the changed metadata:

$ ffmpeg -y -i Null\$katte\$nylterne\ -\ Instinkt-WpMqlB2yp-w.m4a -map 0:a -c:a copy -metadata artist=Null\$katte\$nylterne -metadata title=Instinkt Null\$katte\$nylterne\ -\ Instinkt.m4a

The input metadata is copied to the output file 
in ffmpeg (the application). The application 
cannot know if the muxer will be able to write 
the metadata or not (it may only support some 
specific tags) or if it will just write some 
metadata independently of what was requested to 
make sure valid files are written (as in this 
case).
There may be a bug but I believe the output 
metadata print should just be interpreted as 
what it "tries" to mux.

Yes.

> I'm not sure I follow.

If both streams contain a "real world" start time 
("wallclock time") then FFmpeg should be able to 
synchronize them.
If both start with "0" then I fear synchronization 
will even fail (sometimes) if FFmpeg were infinitely 
fast (which it is not).

It may of course be a bug that FFmpeg cannot read 
the actual starttime (that may be part of the 
stream), I don't know.

Please try to fix your mailer, Carl Eugen

Assuming I can't do anything to fix the start times, is there a way to delay input from one of the streams so I can attempt to adjust the delay manually? 

Thanks,

Hi guys,

When i`m trying to send stream from ffmpeg to ffserver i have got

It`s not firewall problem.
Maybe linux distribution? Its Slackware..

Subject: [FFmpeg-user] Generating an rgb24 pix_fmt solid color using lavfi
	by default
Message-ID: <CAM+h0VvVxO1=B1LpCMKNvdX+jdtqm465GSr3CnBcY9ErHTbGPA@mail.gmail.com>

I try to generate user avatars, using the initials of a user. Here is the
code:

*ffmpeg -v debug -f lavfi -i "color=c=0x0044DD:s=80x80" -vf
"format=pix_fmts=rgb24,drawtext=fontfile=/windows/fonts/arial.ttf:fontsize=40:fontcolor=white:x=(w-text_w)/2:y=(h-text_h)/2:text='KA'"
-vframes 1 -y ka_thumb.png*

Is working fine. But I have one minor problem. The resulting text is
rendered into a rgb24 buffer, and seems fine. But the problem is, the color
I create as *0x0044DD* is in *yuv420p* pixel format by default. What I am
doing as a workaround, first generating a colored buffer in yuv420 pixel
format, then convert it to *rgb24*, then render text over that color in
rgb24 mode. The pixel format conversion step in between seems to be
unneeded. How can I avoid this conversion step, and directly create a
colored background in *rgb24 *pixel format using *lavfi*?

Answered my own question, the "-ss" command does it nicely.

ffmpeg -y -ss 1.3 -i "rtsp://172.24.0.31:554/axis-media/media.amp?camera=1" -i "rtsp://172.24.0.32:554/axis-media/media.amp?camera=1" -filter_complex "[0:1][1:1]amerge" -vn [outputs]

There is.  The MP4 demuxer writes all sort of rubbish into the metadata
struct.  None of which are useful should you be encoding to another file
format.

Do I understand correctly that you believe no 
application will ever want to know the content 
of (for example) the different brand fields?

There is currently no rgb-color filter.

-itsoffset should also work but I am not convinced 
that you will always get the same delay...

Too bad the compiler doesn't tell us where the non-static 
declaration is...

> make: *** [libavdevice/alldevices.o] Error 1
> # grep HAVE_FMINF config.h

It appears to me that fminf() is defined in one 
of your cross-compilation system headers - probably 
math.h - but not available in your C library.
Is that correct or do I miss something?

Or does the cross compiler use the wrong headers?
Or is a linker flag needed to tell the compiler 
where to find fminf()?

Your compiler is eight years old, I don't know 
if this is the problem but I don't think anybody 
can rule it out.

When I try to encode with 320k I see this message at the begining:
size=    6626kB time=00:02:49.58 bitrate= 320.9kbits/s

I've tried with 320k and 256k and both files don't play.

I can't use this option (-write_xing) nor I can't found in 
documentation: https://www.ffmpeg.org/ffmpeg-all.html

And it don't make any difference to use -id3v2_version 3 flag.

Now I've had some time to test this issue more extensively and you're right,
the header really is there. However after encoding I'm using mkvmerge to cut
(split) the file so only the parts I want will be there in the final mkv.
This all condenses down to one problem:

mkvmerge (as well as ffmpeg) in cutting mode does not read all headers that
are included in the mkv file and includes them in the cut mkv file - so the
encoding settings header gets lost if I'm not cutting from the beginning
from the file but from somewhere in let's say the first quarter. It seems
somewhat logical that the two tools don't do that, but it's very unfortunate
for me since I would like to preserve this header in the final mkv file that
comes out after cutting. 

I've read some man pages and tested extracting the tags of the uncut file
(where the "encoding settings" header is still intact) with mkvextract, but
unfortunately it doesn't show it - neither does mkvinfo. Only mediainfo
shows the "encoding settings" tag in the uncut file. 

Any ideas how I could extract this tag somehow from the uncut file and put
it back into the cut file (preferrably with ffmpeg)?

I wanted to suggest a very low bitrate (or none at all) 
to convince you that this is not related to the used 
bitrate (it is not easily possible or maybe even 
impossible to encode mp3 with >320k with FFmpeg).

While applying trial and error using ffmpeg, you might also want to
analyze the failing (and the successful) files with an MP3 diagnosis
tool. There are quite a few out there, even open source. I have used
MP3Diags, and recently found a few others such as mp3check and
mp3val.[*]

I can't tell though whether these tools would detect your issue. Some
apparently only actually process the _headers_.

All I want to do is, generate a solid color in rgb24 pixel format. Is there
any other way to achieve this?
(Other than using an input rgb24 file? I don't want to make this command

Unfortunately you don't include previous discussions, but have you tried

Subject: [FFmpeg-user] Problems getting the very last frames of videos using
	av_read_frame
Message-ID: <54522BE6.5010703@cs.ucl.ac.uk>

Hi,

I am having a problem with reading video files with the ffmpeg api. I am 
building on a python wrapper, that someone else wrote. I noticed a bug, 
but the creator could not solve the issue. So I am trying to hunt it 
down by myself.

The problem is that the wrapper truncates any video I tried it with.

The basic idea of the wrapper is, to use

av_read_frame()

to read frames until it returns a value < 0. That seems to work, and I 
get the right frames back all the time (even using seek of the wrapper), 
except for the last frames. It seems as av_read_frame only reads until 
the last key frame and does not go beyond it.

FFMPEG command line tools, on the other hand, can extract the full video 
sequence and do not omit anything.


I am not sure whether the information I give here is enough to start 
hunting down the bug. I am not experienced at all with the ffmpeg api 
and I am working with the code I have got from the other guy. Let me 
know if you need something else to start tracing the problem.

Thanks,

Peter


Stuff to test the problem:

Wrapper code with line calling av_read_frame:
===========================

https://bitbucket.org/groakat/ffvideo/src/b45143f755ac8da1e6ed4f52a11217af1e093d54/ffvideo/ffvideo.pyx?at=default#cl-231

( you can install the wraper with pip install 
https://bitbucket.org/groakat/ffvideo/get/b45143f755ac.zip)


Rendered test Video (1000 frames numbered from 1..1000):
====================================

https://www.dropbox.com/s/guu33jyy4t7sq53/test.avi?dl=0


Script to generate the video:
=================

First generate frames:

#!/bin/bash
for i in $(seq -f "%05g" 1 1000)
do
         convert -size 51x18 -pointsize 16 -font 
/usr/share/fonts/truetype/freefont/FreeMono.ttf label:$i $i.png
done

Then use to create a video from the image sequence:

ffmpeg -y -f image2 -r 30 -i "%05d.png" -r 30 test.avi


Then test whether ffmpeg can read all frames:

ffmpeg -i "test.avi" -an -f image2 "output_%05d.png"


Python script using the wrapper from above to extract the frames:
========================================

from ffvideo import VideoStream
from scipy.misc import imsave
vs = VideoStream('test.avi', exact_seek=True)

cnt = 0
for frame in vs:
     f = frame.ndarray()
     imsave("frame {0:05d}.png".format(cnt), f)
     cnt += 1

Do you ever see "Unable to decode video picture: %d" from
https://bitbucket.org/groakat/ffvideo/src/b45143f755ac8da1e6ed4f52a11217af1e093d54/ffvideo/ffvideo.pyx?at=default#cl-233
???

There's an example in ffmpeg's doc/ directory, named
demuxing_decoding.c, which uses your described av_read_frame() loop,
and succeeds at reading all 1000 frames.

So the issue is probably somewhere in the python wrapper.

This is quite a bit too old to gain support on this list. :)

The first suggestion would be to build lastest git, and ensure you're
not using "stale" libraries from older installs.

(I don't have enough knowledge to tell you more about how to use libav
properly, I only know the examples. Anyway, there's a separate list for
libav issues: https://ffmpeg.org/mailman/listinfo/libav-user )

Thanks for that lead. I will follow that up and report the results later.

To my knowledge I am not using libav. At least when I last checked ;).

Subject: [FFmpeg-user] DTS Out of Order / DTS & PTS Invalid Dropping
Message-ID: <1414690027434-4667944.post@n4.nabble.com>

Hello FFmpeg-users,


I am struggling to get the concat demuxer working on FFMPEG Version 4.2.4. 

I am attempting to combine multiple image files into a video by using the
command:

ffmpeg -f concat -i myFile.txt output.mp4


I get an output file from the command, but the total time is much shorter
than the time I specify in the file. I am fairly sure it has something to do
with these:

[concat @ 0x3517c20] DTS -230575710986727 < -9214782102262 out of order
DTS -221360928884465, next:40000 st:0 invalid dropping
PTS -221360928884465, next:40000 invalid dropping st:0
DTS -221360928884389, next:80000 st:0 invalid dropping
PTS -221360928884389, next:80000 invalid dropping st:0


*Does anyone have any idea what I can do to get this working?

Message-ID: <CACSc5E1XsQ5RgrhUB9xaJ1gF9uF60rYC5K-NMz23BJhShWBmLQ@mail.gmail.com>

A typical configure line to build FFmpeg for android with NDK would be
something like this:

PLATFORM=$NDK/platforms/android-8/arch-arm
PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86

./configure --target-os=linux \
    --prefix=$PREFIX \
    --enable-cross-compile \
    --extra-libs="-lgcc" \
    --arch=arm \
    --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
    --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
    --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
    --sysroot=$PLATFORM \

So, the script makes its conclusions according to this $PLATFORM sysroot,
libraries contained there, and functions contained in these libraries.

But, when building with android build system, using Android.mk file, this
sysroot is NOT USED. The linking goes against libraries built from Android
source code tree, which are placed in a totally different location.

So, I believe there is nothing wrong with toolchain, there is nothing wrong
with configure script, and there is a lot of wrong in Android build system.
IMO, no additional checks in configure script are needed or would be
helpful, because what we basically have here is configuring FFmpeg
according to one set of the libraries, and building and linking it with
another.

IMO, the best and most secure way to build FFmpeg for Android is
cross-compiling with statically linking everything it needs. But, in my
industry, we have to adapt to Android build system, and this way simply
does not offer elegance and ease of work. Scripts from ffmpeg4android are
my attempt to adapt to the requirements of Android build system and to the
way FFmpeg is usually used by developers working with full Android source
code.

Bottom line, don't bother, there is nothing wrong with configure script.
Blame the Android build system and hacks that have to be made in order to
build FFmpeg by Android build system.

Subject: [FFmpeg-user] Getting H264 elementary stream from mp4
Message-ID: <545221B6.7020706@einfochips.com>

Hi All,

We are having one mp4 file with h264 codec.
we want to feed this file to a video decoder but the decoder requires elementary stream.
So we tried to extract H264 elementary string from mp4 with below ffmpeg commnd,

ffmpeg -i input.mp4 -vcodec copy -vbsf h264_mp4toannexb output.h264

Now with this command we are getting h264 file but this file is not having I-frame in it.
We viewed the file in Hex editor and found that it contains,
00 00 00 01 67 --> SPS frame
00 00 00 01 68 --> PPS frame
But we couldn't find,
00 00 00 01 65 --> I-frmae.

VLC is not able to play the generated h264 file.
ffplay plays the file but very fast (higher fps).

Can anyone suggest what we are doing wrong?
or Any other method to get H264 file?

I rebuild ffmpeg and cleared the issues with

WARNING: library configuration mismatch

(there was indeed libav installed because of a dependency..)

After rebuilding the wrapper, the issue is exactly the same.

Subject: [FFmpeg-user] Problems getting the very last frames of videos
 using av_read_frame
In-Reply-To: <5452E152.4000305@cs.ucl.ac.uk>

I had a close look through

https://www.ffmpeg.org/doxygen/2.1/doc_2examples_2demuxing_8c-example.html

and compared it to what the wrapper is doing. They are pretty similar, 
the biggest difference I could spot so far was in

https://bitbucket.org/groakat/ffvideo/src/b45143f755ac8da1e6ed4f52a11217af1e093d54/ffvideo/ffvideo.pyx?at=default#cl-353

Which means whenever the wrapper starts looping over the frames, it 
starts using av_seek_frame, rather than just to open the video file again.

I noticed a while ago that when doing an accurate seek (in 
get_frame_at_pts of the wrapper) the dts of the stream has an offset, 
therefore I needed to put this hack in, to make the seek precise:

https://bitbucket.org/groakat/ffvideo/src/b45143f755ac8da1e6ed4f52a11217af1e093d54/ffvideo/ffvideo.pyx?at=default#cl-345

The number of frames missing at the end seems to coincide with the +9 
that I hacked into that loop to account for the offset I observed. Back 
then I could not make out where that offset comes from. Now when I read 
the code and the ffmpeg documentation again, I still cannot find why 
there should be an offset. On the other hand, av_read_frame should not 
care about that at all, because it should just return the next frame in 
the stream, regardless of any dts, no?

Anyway, I will continue the bug hunt at Monday. Any suggestions are 
still welcome :)

Yes, I tried ffprobe as well, it doesn't show the tag. No program I tried so
far shows it (tried mkvinfo, Media Player Classic, ffprobe, ffmpeg -i,
mkvextract, mkvpropedit) except for mediainfo. I found a workaround though:
parse the mediainfo output, generate a tags.xml file with a script and add
it to the cut mkv file with mkvmerge --tracks 0:tags.xml. I feel dirty doing
this, but I didn't find any other way. It's probably not the best option.
When I find the time to do so, I'll dig around in the matroska
specifications and/or the x264 source code to see how they accomplish this.

Hello!
I'm trying to convert video stream received from IP camera into 
.mkv container. While processing file ffmpeg prints errors 
described in log file.
What's the reason of arising these errors in log? 
What can I do to eliminate them?

Subject: [FFmpeg-user] Automatically ensuring level-conformance for H.264
	encodes
Message-ID: <000001cff51a$84593f70$8d0bbe50$@gmail.com>

Here is something I started, partly to fulfil a need and partly to explore
Windows shell scripting. As it may be useful to others too, I'm taking the
liberty of sharing it here.

 

The main aim of the attached utilities is to automatically ensure the H.264
level-conformance of arbitrary encodes. In other words, the utilities make
it unnecessary to guess and/or discover the required settings through
trial-and-error test encodes.

 

Automatically ensuring level-conformance is useful for various reasons:

* It ensures maximum compatibility with the widest range of players (even in
cases where strict settings for a specific target are not required)

* Encoding time can be reduced by as much as 50% by using only as many
reference frames as a particular encode's level allows (relevant to
(lib)x264 presets slower than medium, and esp. true for veryslow)

* It takes the guesswork and test encodes out of changing between sources
with different frame sizes, frame rates, bitrates, etc.

 

h264levl calculates, for the given output video parameters, the expected
H.264 level and corresponding maximum reference frames. It supports both
manual and unattended operation, providing appropriate exit codes and
diagnostic output to STDERR for the latter.

 

Here is an example of how h264level can be called from another script:

 

...

setlocal enableextensions

setlocal enabledelayedexpansion

...

rem Calculate H.264 level and maxref

rem --------------------------------

for /f "usebackq tokens=1* delims==" %%i in (`"call h264levl %WIDTH%
%HEIGHT% %FPS% %BITRATE% %PROFILE% 1 1 "`) do (

    if /i [%%i] == [level] (

        set LEVEL=%%j

    ) else if /i [%%i] == [maxref] (

        set MAXREF=%%j

    ) else if /i [%%i] == [x264maxref] (

        set XMAXREF=%%j

    )

)

 

rem Check successful parsing

set PARLIST=

for %%i in (LEVEL MAXREF XMAXREF) do (

    if [!%%i!] == [] (

        if not [!PARLIST!] == [] set PARLIST=!PARLIST!, 

        set PARLIST=!PARLIST!'%%i'

    )

)

if not "%PARLIST%" == "" (

    set ERRMSG=Unable to calculate legal value/s for %PARLIST%^^!

    goto ERRPAUSE

)

...

 

FFx264 is an example of such an encoder wrapper script. In addition to
h264levl, it also uses ffprobe to establish video characteristics such as
frame rate and width and height (the latter two when not over-ridden by the
user).

 

Although FFx264 uses ffmpeg for encoding, its syntax is readily adapted for
e.g. x264.

 

Extract the files from the attachment, rename extensions from *.bta to *.bat
and double-click for instructions.

 

Known restrictions

* These utilities have only been properly tested on 8-bit video

Subject: [FFmpeg-user] Regarding delay in ffserver in reading packets from
	utils.c source code
Message-ID: <CAOYCbicifrR_B4fjTrMR9ZxEVTmCjObVGizQdFfSGV-X5D2SEg@mail.gmail.com>

Hello all,

I am using ffserver for my application that transmits pipe of images to the
webclient html5. I have observed the the function
s->iformat->read_packet(s, pkt) waits for a long time ( aprox. 116 msec)
until the output packet size is a const value 786486, and turns the flag
got_output as 1.

I would appreciate if there is a work around to reduce this delay or
waiting times or looping time.


Thanks in advance,
Tilak

Did you install libvpx?  Was it version 0.9.7 or newer?

What is this?

By installing libvpx or by removing --enable-libvpx

That can't work, x11grab is meant to grab from an X11 display server,
and I somehow doubt that Android uses that.

Did you test according to the suggestion in the neighboring thread?
http://ffmpeg.org/pipermail/ffmpeg-user/2013-January/012942.html

There was never any feedback regarding that:

$ ffmpeg -f fbdev -i /dev/graphics/fb0 out.avi
