Subject: [FFmpeg-user] Web camera and microphone capture via dshow
Message-ID: <1312180505914-3708971.post@n4.nabble.com>

I'm trying to capture and encode video/audio from camera and microphone using
libavcodec, libavformat and libavdevice. It works, video and audio captures,
but after encoding it all is messed: everything is extremely speed up (like
you recorded it at 25 fps and then played at 100). I think I don't get
something about all that pts/dts stuff and synchronization, but I honestly
don't know where to look. ffmpeg unfortunately is very poorly documented in
terms of programming (why? it's so mature, why someone won't write at least
how library works?). I took muxing example from ffmpeg git and modified it
to feed encoders with data from webcam and microphone using av_read_frame
and av_decode_video/audio. Any ideas?

Check the clock speed of your web cam.  I've seen some that clock at
30kHz rather than 90KHz, which will mess up your PTS calculations.

Thank you, that would be a good hint if I only knew how and where to
calculate all that pts/dts stuff and where to put it. I don't understand the
whole process of
1. Take video stream from webcam (av_get_frame?) - probably here some pts
stuff
2. Re-encode it (av_decode_video/av_encode_video?) - and here
3. Write to file/stream over the network (av_interleaved_write_frame?)

I'm going to dig in ffmpeg.c a bit more, but it's really hard to guess
what's going on, because there are very few comments.

On the windows platform I worked with a combination of AviSynth and ffmpeg.
AviSynth has established subtitle support and ffmpeg configured with --enable-avisynth can process these *.avs scripts.
Just a hint, because I didn't do hard subs yet.

As stated before Hard Subs works, but there are come caveats.

If people can put up with it then ok, but what i dont want is to post a patch then have loads of reports of problems, which i already know about.

Subject: [FFmpeg-user] merging or joining videos
Message-ID: <A21CED05-28CF-4655-A905-F6AEEF7ECCF6@gmail.com>

Hello,

I'm wondering if someone can point me in right direction about how I should join together multiple videos?  So if I have video1.avi & video2.avi how do I turn them into joinedvideo.avi?  It doesn't matter to me if I join them after converting or during converting (I'm assuming I have to do it during?).  I'm familiar with cat but I believe this only works on .mpg and I would like a way to work on many files such as .avi or .mp4.  I've also read the instructions in the documentation but I was thinking there's a more updated way than having to convert everything to .mpg first?  Anyways, if someone could point me in the right direction that would be great.  Thanks!

Where is your config.log?

Did you check that you have gcc installed?
(what's the output of gcc --version?)

In general the response is "there is no generic way", the best that
you can achieve right now is to convert to a cattable format (mpeg,
rawvideo) and physically cat or use the concat protocol.

Logical join is not yet possible, although there is a gsoc task
concerning this (can't say about the status of the task itself).

Hi,

I'm trying to convert a series of jpegs to a movie, and I get an error
(log below).
I've done this earlier, without issues, for other jpegs, but for this
particular set, i get the error. I don't know how.

I'm using the latest version of ffmpeg (i built it last week from git
sources), on ubuntu 8.04.

My images can be downloaded on:

Message-ID: <CAOYTo+2kNb7PRj-Gbf8pcTt7nwRaRyT1meM5XzNPcz2M4MpUpg@mail.gmail.com>

Hi,

I'm trying to use ffmpeg to strip one audio stream from a mpegts file
containing 1 video streams and 2 audio.  The ffprobe output from the
input file is:
[mpegts @ 0x1b702a0] max_analyze_duration reached
Input #0, mpegts, from 'in.ts':

    Stream #0.2[0x46]: Audio: aac, 44100 Hz, mono, s16, 79 kb/s

When I run:
  $ ffmpeg -i in.ts -map 0.0 -map 0.1 -acodec copy -vcodec copy out.ts
I get an error:
   [mpegts @ 0x1ced340] aac bitstream not in adts format and extradata missing.
   av_interleaved_write_frame(): Operation not permitted.

Any ideas on what I'm doing wrong?  If the problem is likely in the
input file, any ideas on what might be wrong with it?  The input file
is captured from a third-party proprietary transcoder.

Thanks,
brian

I'm not 100% sure, but I think it also depends on which codec you're
using (.avi is just the container).

I've also had the same problem: All documentation I found mentioned
MPEGs and "cat" or yuv2mpeg for piping things together :( This doesn't
work at all for AVI files.

I found a solution that even works bitproof for audio and video, by
using "mencoder" to merge the videos back together. We're using this
method daily in the Austrian national video archive (=?sterreichische
Mediathek [1][2]) - but only with intraframe codecs (FFv1 / DV) and PCM
for audio. Additionally, it's also possible to merge *and* transcode the
files in one step! :)
Details can be found in a forum post on "das-werkstatt.com" [3].

Additionally, there's an article on "linuxreview.org" about merging
video files [4] - but I must say that I haven't had a good experience
with "avimerge".

Good luck!
Peter B.

Hi,

I'm trying to create an mjpeg from a still image by looping input. 

Using the same command i've been using for a long time, but now anything i do results in a 1 frame output

ffmpeg -y -loop_input -vframes 10 -r 25 -i ~/media_samples/arminFrame.bmp Desktop/MJPEGGED.mjpeg

What i did do is to upgrade ffmpeg to latest git version because of a bug in rotating inputs to conver to mjepg output that i've posted and was fixed.

What could be wrong?

Hi,

Once I had used MP4Box package in Linux for concatenating smaller mp4 files
to get a big one. It worked pretty well, but I had not tried it on AVI
files.

May be you could try MP4Box (which comes as a command line tool when
installing gpac package : http://gpac.wp.institut-telecom.fr/mp4box/).

All the best,
-Venkat.

Hi
Do you see the error message in console "-loop_input is deprecated, use -loop 1"?

If so, change your command to use "-loop 1" something like this:-
ffmpeg -y -loop 1 -vframes 200 -r 25 -i ~/media_samples/arminFrame.bmp Desktop/MJPEGGED.mjpeg

Hi,

I saw no error in the console so didn't know about the deprecation.

Another devloper, Carl Eugen Hoyos answered me also regarding this matter and fixed the latest git version to still be able to use loop_input. I need to know, will this change, will "loop 1" be the only supported switch?

Regards,
DAV

In the long term, yes, as we try to reduce the burden that we have to
maintain (but usually just after a major release).

Hi

ive installed the latest Versions from divx Plus Converter
and ffmpeg on windows 7.

i tried to reproduce the output from divx plus converter because i think
its most compatible (with hardware solutions) and for pcs

ive digitized some home videos with an dvd recorder,
and renamed the .vob files in .mpg
then i converted the mpg with divx plus converter and ffmpeg.

analyzing the videos with ffmpeg,theres the output[1] [2] [4]

i am confused about the differend par / dar output made by ffmpeg,
(with the options [3])
[PAR 67:66 DAR4:3]

is the output generated by ffmpeg ok, or is there an error?

Ensure your toolsets match baseline and your
resolution/framerate/bitrate match level 3.0:
For reference: http://blog.mediacoderhq.com/h264-profiles-and-levels/
Then you will be assured of baseline profile with level 3.0!

I have been using the -profile command in ffmpeg (I used high as an 
argument but presumably baseline would work too).  Then I send commands 
directly to x264 by issuing the following before running ffmpeg:
XOPTS="level=4.1 . . ."
then include the following in the ffmpeg command line:
-x264opts $XOPTS 
I'm not sure why some work through one avenue and some the other, but this 
seems to work.  So you can explicitly set both profile and level.  I've no idea 
what happens if you issue other commands that conflict with the effect of these.

It's amazing (and very frustrating) how when you are trying to solve a
problem your very first attempt can be sooo close to the final solution. Yet
it takes many different attempts, trying many varied things, only to go full
circle and find the solution is a minor variation on your very first
attempt. In this case, after several months working on and off on this,
asking in several forums, the very simple solution is below:

mkvmerge -o video.mkv video.avi
ffmpeg -i video.mkv -vcodec copy -acodec libfaac -ac 2 -ab 160k video.mp4
-acodec copy -newaudio

I don't know why muxing the original avi to mkv allows ffmpeg to be able to
handle it better, but it seems that it does. Perhaps there's a bug with how
ffmpeg handles avi's?

Anyhow, this one is now (finally) solved.
Thanks for all the help,
Phil

Great thanks again I'll be working on this.  I know converting to .mpg first will work but that makes the process longer and than I would have to double convert...

I'm not sure if I'm in a position to say post a patch. :-)  I would definitely try something if it was available but for now I guess I'll have to go another direction.  Hopefully it will be available one day!

Subject: [FFmpeg-user] AVFrame extend life beyond next call to
	avcodec_decode_video2
Message-ID: <CALdTkGGt+0QFF_nxYiNzHzd9Zn-3JqriyLU1r_5fcS4jKj+=kg@mail.gmail.com>

Hi

I would like to extend the life of AVFrame provided by decode_video beyond
the next call to decode_video.

I have tried overriding release_buffer and defer the release_buffer call to
after I no longer need the buffer, however this crashes the application.

e.g.

static void null_release_buffer(AVCodecContext *codec, AVFrame *pic){}

...

old_release_buffer = codec->release_buffer;
codec->release_buffer = null_release_buffer;

... several decode_video calls

for all frames:
    old_release_buffer(&frame);

As a mentioned this strategy doesn't seems to work as the application
crashes.

Any suggestions?

I'm not sure but I don't think that this could works.
Decoder probably can reuse the same buffer for next frames.

that is an *alien* buffer. You should make a copy if you need.

Well the point of this is to avoid making an unnecessary copy.

As I already noticed decoder can reuse the same buffer for next frames
so the only way to get control of this - to create buffers for decoder by
yourself
(and create several such buffers to switch between them).
But decoding maybe much more complicated than you think.

However I didn't find the way for that in current API (only in encoding you
can provide your own frames).
Maybe you will be more lucky but in general I recommend you just do copy if
you really need it ;)

Subject: [FFmpeg-user] distortive video effects
Message-ID: <1312563590774-3721703.post@n4.nabble.com>

hi,

i'm looking for some filters which can be used to distort a source video to
produce some 'funky' effects. i've created some mirror effects using
transpose filter, and can get greyscale through applying formats, but are
there any other filters or configurations which produce distortive, yet
appealing effects?

I was thinking of creating half tone, sepia or swapping the color channels
but it would seem i need to use eq2 fin mencoder for these types of color
manipulations? is there anything like this possible from ffmpegs filters?

i was also looking at creating a 'pixelated' effect, but it would need to be
relatively clean, not so much as a result of lossy processing, is this
possible?

thanks!

Hey Cameron,

Initial research leads to me frei0r
http://ffmpeg.org/libavfilter.html#SEC24

Hope this gets you towards the right direction, it looks like that
libavfilter can connect to the frei0r filter API, so ffmpeg's -vf
frei0r=*effect:parameters

Subject: [FFmpeg-user] bgr24 -> yuv420p darkens?
Message-ID: <CAL1QdWdyaSUT8=dVho0gmYy3-wzPcmJ9ii9Jjd9-vozFJ0HA8Q@mail.gmail.com>

Hello all.  First time here, and first of all thank you for a
marvelous program in ffmpeg.  Everybody everywhere uses it! If I could
donate some money to it, I would (I know somewhere it said you don't
take donations though).
Ok, observations.
With this bmp (bgr24) [1], if I use ffplay on it, it comes out
"darkened" and/or "with a red hue" for whatever reason.


[1] http://rogerdpack.t28.net/incoming/mostly_white.bmp the "white"
outermost backgrounded window looks somewhat red
http://rogerdpack.t28.net/incoming/red_hue.bmp within the ffplay
window.

Here's the command line output (mingw build, but it seems to reproduce
with any platform/version).

Subject: [FFmpeg-user] File for preset 'baseline' not found
Message-ID: <4E3CA074.50502@thelounge.net>

Hi

N-31788-ge1e3d79 says "File for preset 'baseline' not found"

without twopass-encoding fails with
"maybe incorrect parameters such as bit_rate, rate, width or height"

it is a little bit frustrating that vpre is permanently changed
because if you write wrappers it is impossible to say on what
foreign builds they can be used :-(

has anybody an idea what on the two command-lines will break 2pass
encoding and what made the additional -vpre baseline on both
of them different to be able remove vpre completly?

As mentioned, the frei0r filter allows to access all the frei0r
effects, and many Mplayer/mencoder filters are available through the
mp wrapper. 

And I'd be glad to help someone porting more filters (e.g. from
virtualdub/effectv).

Maybe -vf frei0r=pixeliz0r?

just think a second about what GPL means
do you touch ffmpeg or include any headers?
no you do not if you call it only via CLI

Thanks Reindl,

Since I am new to this. To take the safer side I wanted to be more specific
about my implementation.

I am using FFMpeg.exe command line tool programmatically and running
FFMpeg.exe commands programmatically.
For this I need to distribute FFMpeg.exe command line tool with my
proprietary software.

I hope this will not cause any Legal issue..

Please reply..

Thanks
Prashant

as long as you only call a binary application via

it is GPL, LGPL, Commerical.....

the other thing is copying the binary-app and this

Calling FFmpeg via its command line interface is generally accepted as a way to keep your software proprietary.  Some purists disagree, but their's no court decisions I'm aware of that have addressed the question.

You could point your customers to ffmpeg.org, with detailed instructions, and have them install it themselves.  You might discover that some will already have it installed.

> I hope this will not cause any Legal issue..

It might.  Any time you distribute GPL software, you must offer your customers the source code and build instructions for the version you ship.  If they can compile a new copy of ffmpeg.exe to use with your software, you've given them enough material.

I hope that it is obvious that you need to compile FFmpeg.exe yourself, to be sure that your customers will also be able to.  Similarly, as the GPL version of FFmpeg includes other GPL libraries, you need to do the same with all of those libraries.

It is *not* sufficient to point your customers at the same website you got a copy of FFmpeg.exe from.

> http://www.ffmpeg.org/legal.html

Most of the legal advice on the link above applies to "LGPL" usage of FFmpeg, which you are avoiding.  But the patent mini-FAQ would still apply.

Of course, I Am Not A Lawyer, so the above is solely my opinion.  I suggest you read the actual GPL and make sure you understand it.  If you can't, you should hire a real lawyer who has experience in this area.

HTH,

Phil

This would be one of the reasons why the GPL and its derivatives make  
absolutely no sense whatsoever.

What's the functional difference?!

What's the situation with including an ffmpeg CLI binary with rental  
equipment?

If I do that, if it's an embedded system, how do I make the required  
source code offer?

None of this has been thought through very carefully, has it...

for YOU if YOU want use the code like YOU WANT

it makes sense if the developer DECIDED that every derived code
has to be available too and he decided this be selecting the license

so what do you try to tell us?
that YOU do not like the license
fine, nobody is forcing you to use anything you do not like

... i.e. export first frame of each new scene as an image. This effectively
generates a storyboard.
It also would be an enormous help in identifying added and deleted scenes
when comparing 2 videos.

this was the last answer in that thread:

I wonder if any code from the BBC R&D's open source (LGPL) Video Shot
Change Detector could be used?

The netiquette says no smalltalk, still I want to say how grateful I am for
your reply. Hope that's ok.

Here is other code I found for scene change detection:
(being coding illiterate I don't know how userful it is)

There is a reason, and it is a legal one.

The legal basis that allows the viral clause of the GPL to work is that
under copyright law, one can not distribute a works without the consent of
its author, and the author can pose almost any condition to give his
consent.

When building a program using a library, even a dynamically linked one, part
of the library is embedded in the final binary: the library's copyright
owner can pose his condition on the distribution of said binary.

On the other hand, a program that calls ffmpeg as an external program, no
part of ffmpeg is embedded. The program can even be built on a system where
ffmpeg is not installed and never was. Therefore, ffmpeg's copyright owners
can not pose any condition.

Unfortunately, a variation on this argument could allow anyone to distribute
a proprietary program linked to GPL ffmpeg libraries; but I will not explain
my reasoning publicly here, as I consider it a violation of the spirit of
the license and do not want to encourage it.

can you stop this childish polemic?

as developer you have the copyright and can define
the rules under which your software/code  is used
and damned this is a legal thing and not a wish

so what exactly is your problem?

this is typically the argumentation of people who are pissed off
that there is code they would like too use, too lazy to write
it self and not willing to accept that the developer decided
he is willing to offer his code for free but not willing
taht peopole take it, make money with it and does not give
back improvements

you call the rules stupid - i call you stupid
and no i am not contributor to ffmpeg, this is a generally thing

Respectfully, I have noticed, Mr. Rhodes, that although
you are frequently one to contribute a comment to this
list, your comments are hardly constructive and helpful
to a set of users and developers intent on working with
and on ffmpeg.

You are, of course, free to continue your oft-repeated
comments on the problems with ffmpeg, open-source and
etc. Just please consider that this isn't truly helping
the users and engineers on this code. I am certain that
I speak for a few of us when I say, I really wish you
would simply acknowledge that we acknowledge your
reservations, and simply be done with it.

I value your criticisms, but after a while, repetition
changes signal to noise, in this case.

With all due respect,

Well, it is intended to.

The fact that what I'm saying is unpopular does not make it untrue.

You could also consider the fact that nobody has answered the question -  
because, I suspect, it is unanswerable.

If I build an embedded device with ffmpeg in it and rent or sell that  
device to someone, how do I comply? Who, at what postal address, is the  
legal representative of the ffmpeg project authorised to act on its behalf  
in terms of license negotiations?

The answer to those two questions is, I suspect, "nobody knows", because  
under the current rules nobody can possibly know.

Again the potential benefits of open discourse...

I assume this q is coming up and.....

It is my understanding, perhaps flawed, that if the ffmpeg
technology is used at the 'source' level (meaning, actual
C from ffmpeg is used in a product) then this product is
subject to GPL. This means that (again, as I understand it(
one (meaning the 'device' developer and seller) would be
compelled to publish the code incorporating the ffmpeg sources.

I may have this wrong, but I am trying..... :)

If, however, the code is used as a set of 'linked libraries'
then I (again, may be wrong) believe that the LGPL clause
kicks in.

(are ffmpeg libraries under LGPL?)

Thus, one would have to supply attribution to ffmpeg
("....my code uses ffmpeg, copyright original authors,
etc...") and also centrally publish source to ffmpeg
or link to library as used, in question.

I kind of hope I have this wrong, so that a better
expert will note my errors and I can learn a bit from
this exchange....

> Who, at what postal address, is the

It's my understanding that there are a group of core developers,
no? At least under US law, the copyright is theirs. If they
publish it under an open source license, and the terms of
the license are violated, a civil suit can be filed against
the breaching party.

You may be right, but perhaps we can try to get this cleared
up....let's give it a whirl.

Any correcting comments most welcome.

Subject: [FFmpeg-user] Subtitle stream added to QT MOV format even when -sn
	switch used
Message-ID: <CAPG4a_nga5NbenYezb0A2a1SAr7qO8zGMXe=Tg6dEZ_KOJ+59w@mail.gmail.com>

Hi,

Apologies if this has been posted/solved elsewhere? I searched and did
not find this particular issue.

Also, apologies if I do not include the correct set of information.
If I am missing something then please let me know and I will repost.

I am using FFMPEG to encode from an Matroska video (mkv) to a
Quicktime mov file. ?Issue is that mov file includes subtitle stream
even when -sn switch is used. ?This occurs with both the Fedora 12
current packaged binary (ffmpeg-0.7-45_rc1.fc12.x86_64) and with a
build from GIT source (about one month old). ?It also happens when
using the MacPorts FFMPEG. ?This does not seem to be a problem when
converting from other file formats to mov (e.g. m2ts to mov)

Here is a little example using the precompiled binary Fedora package.
Notice that the second time I run ffmpeg the subtitle stream appears.

Any help or suggestions would be much appreciated.

Thanks!
Evan

Subject: [FFmpeg-user] c implementation of a basic ffmpeg command
Message-ID: <73A4FB20-6A86-4AE8-8043-39310504580B@gmail.com>


I have successfully created an xcode project with ffmpeg. I am just learning c and would like to carry out some basic ffmpeg command line equivalents , such as:

ffmpeg -y -ss 00:00:30.00 -t 59 -i songIn -ab 24k songOut

How would this line be implemented in objective c, and is there any tutorials out there that would explain it. I have searched and found that all examples and tutorials are directed to video only. Thanks for your help.

To comply you can simply put on your website the source code used and
put a link appearing in the product.
Like a legal notice (ex : this product contain programs under the gpl
licence : ....).
you don't need to contact a legal representative of the project.

This is stupid. AOL along with thousands of others have sold  devices
with GPL code embedded. The first one I bought was the "Gateway
Connected Touch Pad" (GCTP) a device which ran Midori Linux and AOL?s
proprietary client for Linux on top.

Guess what? AOL made the full source code available, both the original
Linux source code along with the modifications AOL had to do to make
it run on the device

http://web.archive.org/web/20040414212406/http://opensource.aol.com/

"This is the host site for Open Source software used in the Instant
AOL device. Below are links to the extended version of Transmeta
Corporation's MidoriTM Linux distribution. These images contain
MidoriTM and the Instant AOL modifications to MidoriTM.

A variety of Open Source licenses are used within MidoriTM(depending
on the area), the most common one is the GNU General Public License.
For full license details, see source code headers in individual Linux
packages."

So, to answer your question, that is how you?re supposed to comply.

Another example is Linksys, whose Wi-Fi routers run Linux. And here is
how they comply.

http://homesupport.cisco.com/en-us/gplcodecenter

But then you ask:

"If I build an embedded device with ffmpeg in it and rent or sell that
device to someone, how do I comply? Who, at what postal address, is
the legal representative of the ffmpeg project authorised to act on
its behalf in terms of license negotiations?"

There is nothing to negotiate. You comply like Cisco or AOL did, by
stating somewhere on the documentation and/or web site that the device
includes GPL-licensed software,and make an offer to provide the source
code to interested parties so if they want to fix a bug without your
assistance on the GPL code, or re-use your GPL binary on a similar
device, they can.

If you do ship a device with GPL software but fail to provide the
source, you will find that some hackers will eventually realize about
this and you and your company listed on the GPL-violations site, with
possible legal hassle.

I respectfully suggest you take further GPL-related queries to the
GPL-legal mailing list

http://gpl-violations.org/mailinglists.html

Subject: [FFmpeg-user] Running ffplay without X
Message-ID: <15328F14E709E14F86C3FF7392216A5B013E69B6@SESTIVDC02P.Apica.local>

Hi,

I would like to get out stats from a running stream like bytes sent/received, seconds played etc.
I decided to use ffplay with its "-stats"-command to get information about a stream.

The problem I'm having is that I'm trying to use ffplay on a debian without the x server, which doesn't work for me.
I know that ffplay want to use a gui but I'm a bit unsure if it can be used without a gui and only command line?

This is the error that I'm getting:
"(*) DirectFB/Core: Single Application Core. (2008-08-18 12:36)
(!) Direct/Util: opening '/dev/fb0' and '/dev/fb/0' failed
    --> No such file or directory
(!) DirectFB/FBDev: Error opening framebuffer device!
(!) DirectFB/FBDev: Use 'fbdev' option or set FRAMEBUFFER environment variable.
(!) DirectFB/Core: Could not initialize 'system' core!
    --> Initialization error!
Could not initialize SDL - DirectFBCreate: Initialization error!"
Is it possible to use ffplay with only command line and how do I do that?
Do you have any other recommendation of what to use (if ffplay is the wrong choice for my misson).
I would like to check info/stats on streams using http/rtsp/rtmp (and all its variants).
Regards
Erik

I don't know how to do this in ffmpeg along, but you could pipe yuv4mpegpipe output from ffmpeg to yuvdiff. See: http://www.silicontrip.net/~mark/view.php/lavtools/20100906-yuvdiff

For instance:
ffmpeg -i input_file.mov -pix_fmt yuv420p -f yuv4mpegpipe - | yuvdiff -g > frame_difference_values.txt

You'll get a two column output of frame number and a number representing the difference between the current frame and the prior. Then determine a threshold for what is a scene cut, parse the output to get the frame numbers of cuts, then use those to cut the desired frames out.

For getting a list of detected scene cut offsets, I can also suggest  
using "shotdetect" by Johan Mathe:
http://shotdetect.nonutc.fr/

(NOTE: The current release is quite old and contains some issues, but  
I've fixed some of them and Johan agreed to merge them back upstream -  
there's no official release containing those changes, but if you need  
them, let me know)

...you could take its output XML with the frame offset numbers, and  
use a XSLT stylesheet to generate the necessary ffmpeg commands which  
actually perform the cuts. However, that's just some implementation  
idea from the top of my head :)

Or is there any way to feed some sort of "edit list" to ffmpeg?

Regards,
Peter B.

So you say.

No offence intended but this is exactly why it's important to have a point  
of contact. Whatever "the ffmpeg project" is, it's a sort of amorphous  
blob of people who claim to be involved in development, with no real  
definition of who's in charge, who can speak with authority, who can say  
"yes do that, that's OK" and have that actually be binding. Right now,  
anyone could say anything and someone else could countermand it a week  
later.

Sure, I could go ask on gnu-violations.org, but who are they other than  
yet another third party with no legal relationship to the informal group  
of software engineers who appear, notionally, to be in charge.

You see why this is a problem.

Perhaps it's useful to consider 'how' this is important....
(from me, this is partially because I am really trying to
understand the point you are proposing....)

So, allow us to understand in context....

The notion is, this is relevant in terms of a situation where
there is a commercial interest in the technology? Then,
because commercial interest must have a point of contact
(the ffmpeg-interested party) there should be a
corresponding point of contact in the ffmpeg community?

Or am I wildly off-base ?

I guess this kind of doesn't matter if it's a hobbyist....

it does not seem to matter if a party uses the ffmpeg
tool in a shop for a bunch of stuff, free or commercial,
but does not distribute binary or other code, just uses
tool for a service....

Does not seem relevant to a student or research
institute where investigation is being done/tool
is being used, but there is no profit...
(soft point here?)

There may be other cases, but it seems that the only
real point here is in a commercial context.

Thoughts?

That is why from a legal perspective (which seems to be what you are 
interested in) it does not matter what someone *says*. For it to be 
legally binding, you would have to prove that you concluded an oral 
contract (or via e-mail). Good luck with that. Why would you want to do 
that? It's just calling for trouble. There already *is* a written 
contract (the licence). This is the set of rules which are legally binding.

This is the legal side of the issue. Concerning the moral/ethical side 
there have been lots of replies already.

A licence like GPL2 is a list of rights (and rules) given by the
author(s) to the users, so you don't need to ask someone how to do
things with FFMpeg just read the licence, in addition there are several
case with the GPL licence it'll be easy to do a research and find what
you want.

See you soon

This interpretation is, at best, optimistic.

I'll repeat my example again: what if I build an embedded device, and rent  
it to people?

The GPL (and similar licenses) don't talk about this.

It's a non-issue because you're too busy trolling the mailing list to ever build an embedded device and rent it to anyone.

Nobody forces you to use ffmpeg, if you find the licensing unsuitable, use something with a license to your liking.

Hi,

Yes, I thought of that and it is my backup way of doing it. It would be better to have ffplay running plain without xvfb, if it is supported?

To rent is not to sell, an ISP called Free has done this and has never
given the source code there was a case on this.
The judge said that the device rented by Free was part of the Free
network and there is no obligation to give the source code.

You can argue about the GPL, but always asking the same question when
people have given reasonable answers is definitely trolling.

This is not the first time this has happened.
I'll give you a last warning. You will be banned.

No, it isn't the first time, so I will paraphrase the same response I gave  
before.

Much as I regret upsetting one of the most professional and qualified
members of this list, I'm not really in a position to stop you doing
anything you want - if you feel that's the best response, then you should  
go
ahead and do it.

You are certainly in no position to demand anything of me.

so why are you trolling here instead write your own software with

Dear experts,

I am working on a project to add video watermark to mpeg2 videos.  I am
using window server 2008 x64 and E3-12XX CPU.  The watermark need to be
moving text and png.  I am using old version of ffmpeg with vhook to do
that.  Since I need to do them in volume.  Each video need to have the name
of the customer watermarked on it.  So one video with have more than 1000
copies with different watermark on them.  The ffmpeg vhook solution is
working but I am looking for faster solution.  

1) Is there anyway to do video watermark with newer version of ffmpeg (at
least multi-threade)?  vhook is not supported in the new ffmpeg release.  I
am stuck here withthe old version.
2) Is there anyone who can offer me a solution and even better if CUDA can
be incorporated.  Or anyone know how to use Intel ipp with ffmpeg?

I am willing to pay for either of both of the above a solution.

Please point me out which direction to find such experts.

thanks

Scene-detection looks like a much requested feature, please file a
feature request on the issue tracker. I'll hope we'll be able to find
some mechanisms for allowing users to (micro?)fund and vote on the
issues/features they want to be fixed.

On the technical side: this has been already discussed on
ffmpeg-devel, an underkill solution may be as simple as tweaking the
select filter and adopt a simple pixel-per-pixel average difference as
metric.

For images with moving objects that's not a proper solution, and you
need motion estimation code, which is already integrated in
libavcodec, so the ideal solution would be to refactor the ME code in
libavcodec and move it to libavutil. By doing this you may also
improve the code itself, and thus improve the codecs using it at the
same time.

Subject: [FFmpeg-user] Subtitle stream added to QT MOV format even when -sn
	switch used
Message-ID: <CAPG4a_=q0NX5ZZZabqwtjD7p=wiRBBG1SWJByiroSPLGUjaH_A@mail.gmail.com>

Hi,

Apologies if this has been posted/solved elsewhere? I searched and did
not find this particular issue.  Also, I tried to post this last night
and it did
not seem to go through -- sorry if this is a double-post.

I am using FFMPEG to encode from an Matroska video (mkv) to a
Quicktime mov file.  Issue is that mov file includes subtitle stream
even when -sn switch is used.  This occurs with both the Fedora 12
current packaged binary (ffmpeg-0.7-45_rc1.fc12.x86_64) and with a
build from GIT source (about one month old).  It also happens when
using the MacPorts FFMPEG.  This does not seem to be a problem when
converting from other file formats to mov (e.g. m2ts to mov)

Here is a little example using the precompiled binary Fedora package.
The second time I run ffmpeg the subtitle stream appears even though
conversion was run with -sn the first time.

Any help or suggestions would be much appreciated.

Thanks!
Evan

Hi guys,

I have a simple uncompressed WAV file, which i want to split. The problem is that i amost never get the precise exact amount of sound i want, as per example:

ffmpeg -i 17203588.wav? -ss 1 -t 1 17203588_cut.wav

should cut out exactly one second from the stream, but:

ffmpeg -i 17203588_cut.wav?

outputs: 
ffmpeg version N-31743-g324b8ad, Copyright (c) 2000-2011 the FFmpeg developers
? built on Aug? 3 2011 15:13:54 with gcc 4.5.2
.....
Input #0, wav, from '/home/alexandru-david/Exporter/exportWAV/userclips/17203588_cut.wav':
? Duration: 00:00:00.99, bitrate: 1411 kb/s
??? Stream #0.0: Audio: pcm_s16le, 44100 Hz, 2 channels, s16, 1411 kb/s
At least one output file must be specified


This is a pretty happy case though, sometimes i'm missing more millis from the output. And it's very important to get the precise length i need because i'm concatting those WAVs and sometimes i get little pauses at concat time in the final sound.

Any ideas, tips or tricks for me?

Thanks in advance,

Regards,
DAV

Not sure why FFmpeg would not work, but if you can simply copy bytes into a 
new file,  and change a few bytes here and there, you can go sample 
accurate.
Wave is a pretty simple format, see here:
https://ccrma.stanford.edu/courses/422/projects/WaveFormat/

So, copy the header, dive into the datastream and append as much as you 
need, then modify size according to the amount of bytes copied.
If you really want to do it well, look around your desired cut point to see 
if you can find low volume values, or at least close to equal values with 
the previous/next clip, to avoid pops in the output.

Or, have a look at SOX...

Thanks, i did have SOX as an option, but actually i found a while ago that it too was inacurate. I have a newer version now and from initial tests it seems to do the job great. Will use that.

Thanks again.

For ideas/details about how to implement a scene-cut detection, I  
would suggest looking at the code of shotdetect (Johan Mathe is really  
nice, and the license is LGPL by the way).
His approach is actually really simple and straightforward, and we've  
now been using it in our long-term archive solution for quite a while  
and could provide information based on hands-on experience about what  
to expect from that straight-forwards algorithm.

I'm mentioning this, because I think Johan's algorithm is merely a  
variation of a "pixel-per-pixel average difference" and it works  
surprisingly well - on really different kinds of content.

Hi,

does anyone know/can recommend a filter (maybe mplayer, frei0r?) that can reduce flicker in video footage caused by flickering light (in my case a problem with a cheap LED video lamp)?

Thanks in advance,

Wow, what a learning experience this has been. First I need to throw out a
round of apologies to the list for my attitude. I thought I had a working
instance of ffmpeg, libx264 and qt-faststart on my server and it turns out
that what I had was a mess instead. Rebuilt everything fresh and I know have
a working version of all three with a nice collection of vpre libs for
libx264. Looking into faststart.py next just to make it safe for the avg
user. 
[>] 
What I had put up, minus the qscale - thanks for noticing that, actually
should've worked yet did not. I never once tried to send the command through
anything else but a php script which didn't provide any error reporting and
I should've run it through a CLI. I know better and just got lazy and a
little too comfortable with my PHP skills for my own good. 

Having said all of this I know have two questions:
1) how can I pipe the qt-faststart command into my php exec() or CLI
statement so that ffmpeg finishes the transcoding before qt tries to do the
atom move?
2) if you look (black screen) at this video,
http://hallmarcwebsites.com/wrdp/wp-content/uploads/2011/08/final-stren.mp4
on a AT&T Motorola Backflip (with Android 2.1u1) you get audio and no video.
Here are the ffmpeg settings I used to do the transcoding (let me know what
I have left out)

ffmpeg -i INPUT_FILE.mov -r 25 -b 864k -acodec libfaac -ab 96k -ar 44100 -ac
2 -vcodec libx264 -vpre lossless_max -async 1 OUTPUT_FILE.mp4

Hi Marc. How about putting your ffmpeg and qt-faststart commands into a bash script, one after the other, and execing that instead?

Hmm that may be the thing and I have been considering it however, now that I
have this running through a WordPress plugin environment and something I
want to pass on for other WordPress users, bash file isn't doable. Need to
stick with PHP exec(). I'm thinking I need to write a class that will check
for a successful shell output and then fire off the qt-faststart.

The resulting mp4 file has a pronounced shudder every 10-15 seconds or 
so. I assume this is related. How do I fix it?

You need to read from AVFrame.data[4] and .linesize[4], *the layout
depends on the pixel format used*.

Check libavutil/pixfmt.h, libavutil/pixdesc.h, and
libavutil/imgutils.h for more information about each pixel format
layout (and you can use libswscale for converting to the wanted
format).

building tool say you explicitly that library 'libopenjpeg' doesn't found.
But you request it. So - did you install / build this 3rd-party library?

hi you...

i have a question.. I was reading and AvFrame.data have the structure
AvFrame.data[0] = RED
AvFrame.data[1] = GREEN
AvFrame.data[2] = BLUE
AvFrame.data[3] = ALPHA

then if i read from data[4] ( i supouse you was refering data[3]), i will
have only alpha, no?, or am i wrong about the AvFram.data structure?

Never did get ffmpeg to work: seems to be broken. But found:

https://sites.google.com/site/linuxencoding/x264-encoding-guide

and used:

  mplayer -nosound -benchmark -vo yuv4mpeg:file=>(x264 --demuxer y4m 
--crf 20 --threads auto --output output.264 - 2>x264.log) 
2011-Dinner-Theater.m2t

That works. No shudder.

Seems odd since mplayer uses ffmpeg for its plumbing, but....

C language adopts 0-indexing, so data[3] is alpha.

Assuming you're reading from a PIX_FMT_RGBA image, you get:

// first line of data
data[0] = RGBARGBARGBA....LINE_PADDING...RGBARGBARGBA...LINE_PADDING...RGBARGBARGBA...

so for accessing the first byte of pixel x,y you do:
uint8_t v = data[0] + y * linesize[0] + x * linestep

in this case linestep = 4 (how many bytes in a pixel)

Note that:
linesize != width * linestep

since each line data needs to be aligned (the exact amount of
alignment - and thus of padding bytes, depends on architecture).

For other pixel formats the exact layout (components disposition in
data, linestep etc.) may be different, and you need to read/understand
pixfmt.h/pixdesc.h for dealing with them.

Hi Stefano

in your sample
data[0] =
RGBARGBARGBA....LINE_PADDING...RGBARGBARGBA...LINE_PADDING...RGBARGBARGBA..

what you reffer LINE_PADDING? what is this?

sorry my ingnorance but is the first time in image processing

OK, almost there still can't figure out why my Backflip plays the audio and
no video.
Any idea where I might look to try to correct his?
here is what I have so far:
---BEGIN CODE---
$str = "ffmpeg -i ".$originalFileUrl." -vcodec libx264 -vpre lossless_medium
-vpre baseline -acodec libfaac -ab 96k -ar 44100 -ac 2 ".$newFile;	
exec($str);
---END CODE---

then I run it through qt-faststart as the output from above is always set to
mp4 and I want to make sure it can play on Smart devices

Also, when I add these parameters, -s 480x320 -aspect 3:2, to the line above
I get a file that is 4x's larger than the original. How can I limit this?

Hi,

Memory is divided into segments, LINE_PADDING  is aligned to the next memory segment.

e.g.
memory segment size is 2048 bytes, and one line video is 1536 bytes, the 
remaining bytes of the segment is called compensatory

maybe just -vf scale will match it with the desired output [?]

Subject: [FFmpeg-user] ffmpeg for DLNA
Message-ID: <201108102047.10506.mirsev@cicese.mx>

Hello,

Probably this or similar question has been already asked... I'm trying to use 
minidlna server (https://sourceforge.net/projects/minidlna/) for playing back 
AVCHD video recorded by Panasonic camcorder on TV connected to DLNA capable 
Samsung BD-C6900 blu-ray player. In general, this setup works but...

1. Every short scene recorded by the camcorder is stored as separate file
   (h.264 + ac3 streams in a mpeg-ts container).
2. The player and minidlna server play every file separately.
3. Buffering time for every file is quite long (several seconds).

So, when playing back complete unedited video, most of the time is spent for 
buffering between files.

I would like to add a capability to minidlna server to represent a sequence of 
files as a continuous mpeg-ts stream, so that buffering will be only at the 
beginning of the playback or when jumping forth and back over video.

As I see, this will require to read TS from the files, fix DTS and PTS for all 
video/audio packets to play them smoothly, and stream them to the player. Do I 
miss anything?

My question is basically this: is ffmpeg library set a right thing to do this 
task? I have experience in programming but never dealt with any MPEG video. So, 
any links to similar software using ffmpeg will be appreciated.

Thank you and best regards,

Serguei.

Hi,

I'm trying to use ffmpeg to get images from a live video stream. I use a 
command like:

ffmpeg -i rtmp://mylocation/myVideo -r 1 img%d.jpg

The problem is ffmpeg waits even minutes after writing the first image. 
How could I avoid this delay?

It might work with "broken" PTS times for the packets, as well.
One thing related (though off topic) might be VLC's "sout-keep" and
mencoder's "reindex" ffserver might work here, too.

I'm not sure. I tried just to concatenate files and play them but this does not 
work well.

Thank you for your reply. Unfortunately, these words still mean nothing to me. 
Any links to the docs or some examples? 

I'm going to start to dig into ffmpeg APIs but they are huge. As I see, I need 
to check only one or two layers: stream container and packets/frames without 
video/audio decoding:

1. open an input file
2. get streams info
3. open output MPEG transport stream
4. loop: (get packet/frame, fix DTS/PTS, send it to the output stream)
5. open next input file, and so on.

I would appreciate if someone familiar with ffmpeg API shows me a right 
direction: where to start. Is there anything like "ffmpeg for idiots"? :)

Message-ID: <CALdTkGGdM05wRRGGTXxt=-tdkOCrm4b=7T88M1GjzzsZRJ=ySg@mail.gmail.com>

I'm playing around a bit with thread decoding of H264. I would like to
decode slices.

However, I get an access violation inside of "thread_execute" at the line
"int r = func(s, reinterpret_cast<uint8_t*>(arg) + n*size);".

This works just fine with mpeg2 decoding.

Any ideas as to why I'm getting an access violation? Is it a bug in the
sliced h264 decoder, or am I doing something wrong?

int thread_execute(AVCodecContext* s, int (*func)(AVCodecContext *c2, void
*arg2), void* arg, int* ret, int count, int size)
{
for(size_t n = 0; n < count; ++n) // will be parallel_for
{
int r = func(s, reinterpret_cast<uint8_t*>(arg) + n*size);
if(ret)
      ret[n] = r;
}
return 0;
}

void thread_init(AVCodecContext* s)
{
static const size_t MAX_THREADS = 16; // See mpegvideo.h
static int dummy_opaque;

    s->active_thread_type = FF_THREAD_SLICE;
s->thread_opaque  = &dummy_opaque;
    s->execute  = thread_execute;
    //s->execute2  = thread_execute2; not used
    s->thread_count  = MAX_THREADS; // We are using a task-scheduler, so use
as many "threads/tasks" as possible.
}

void thread_free(AVCodecContext* s)
{
if(!s->thread_opaque)
return;

s->thread_opaque = nullptr;
}

int custom_avcodec_open(AVCodecContext* avctx, AVCodec* codec)
{
avctx->thread_count = 1;
if((codec->id == CODEC_ID_H264) &&
  (codec->capabilities & CODEC_CAP_SLICE_THREADS) &&
  (avctx->thread_type & FF_THREAD_SLICE))
{
thread_init(avctx);
}
// ff_thread_init will not be executed since thread_count == 1.
return avcodec_open(avctx, codec);
}

int custom_avcodec_close(AVCodecContext* avctx)
{
thread_free(avctx);
// ff_thread_free will not be executed since thread_opaque == nullptr.

Did you try concatenating them with ffmpeg or mencoder? (make a separate file).

Message-ID: <CAOYTo+0qqswVJKKiiDv7EaaAgW=zy+kTW4fwu4jk5i5tyk5xmQ@mail.gmail.com>

Hi,

I'm trying to use lib(avcodec|format) to discard one audio stream
(PID) from an input mpegts file.  Using ffmpeg, the command line:
  $ ffmpeg -y -i infile.ts -vcodec copy -acodec copy outfile.ts -map
0.0 -map 0.2
does exactly what I want, but I want to avoid the fork&exec of ffmpeg
and use the library interface directly.

I can't figure out how to setup the input and output contexts.  If I
don't add the filtered stream to the output context,
av_interleaved_write_frame() will segfault since it accesses stream[n]
with n == 2, but the output context only contains a list of streams
for ids 0 and 1.  If I add the input stream to the output context, the
PMT contains both audio PIDs, which isn't right.

Does the 'discard' attribute of AVStream help?  I tried setting it to
AVDISCARD_ALL for the stream I want to remove but it doesn't seem to
do much of anything.

Can anyone shed some light on this?  The ffmpeg binary does the right
thing so I know it's possible.

Thanks,
brian

Hi,


Sorry to bother.


I have met a problem when using ffmpeg libs to generate a mp4 video, described as below.


1. I have a sequence of image frames, and a sequence of audio files (.caf format), I need to use them to generate a mp4 video.
2. There are two streams to operate, one for video and the other for audio.
3. Video stream works fine.
4. I need to encode the audio files into specified frames(based on video stream) to sync the video and audio.
5. Now, I cannot control which frame (or when) to add the audio files, the audio are played at the very beginning of the mp4 file continuously.


Any suggestions would be grateful, thanks very much.

usually audio manipulations are better handled by another project called sox
http://sox.sourceforge.net/
An alternative with a GUI would be audacity http://audacity.sourceforge.net/

I'm not quite sure how you want to arrange the audio and video, but I'm
assuming you have image1, image2, image3, etc and you want audio1, audio2,
audio3 to align respectively. In which case, I would suggest muxing the
individual audio/video segments alone at first, and then concat the
resultant videos together?

I hope this helps, if it doesn't can you be a bit clearer on how you want to
arrange the image and audio sequences? Also, a command line that you are
currently working with may be relevant, so you could also include that?

No, here I meant the concatenation by cat command. This did not work even though 
files were just MPEG transport streams. They do not contain a header like AVI 
files, right?

If I concatenate them using mencoder with -vc copy -ac copy options, it works 
quite well. But I believe that mencoder recalculates DTS and PTS to make frames 
really sequential, so this was not a simple concatenation of streams.

Consider using the DRAWTEXT filter - it will do /exactly/ what you want.

Ok, that's what I'was looking for.  
 
So, I just have to add the next line into the existing exec( ) commandline? 
 
drawtext="fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf: 
text='(c)THISCLIPISMINE.XYZ' "
 
 
And ofcourse I have to check on the server where FFMPEG is running:
 
1) if the libfreetype is enabled: (--enable libfree type ) 
and 
2) if the the desired font is avaible.

Yes (re libfreetype etc).

And consult the documentation - http://www.ffmpeg.org/libavfilter.html#SEC20

According to http://ffmpeg.zeranoe.com/forum/viewtopic.php?f=3&t=27&start=10
(last post) it should "just work" though I haven't tried it myself,
and apparently it isn't easy...

Make sure you are using the most recent libav* libraries in compiling
It seems you also should try --enable-avisynth ? Not sure... ref:
http://ffmpeg.org/faq.html#SEC26

If you're looking for an alternative, VLC has a directshow capture mode that
works moderately well. Seeing as how VLC is built on the same libraries as
ffmpeg, I'm assuming it does the same job as if you got the -f dshow to work
on the command line tool.

Also, vlc works as a command line tool itself, try using it's syntax found
here: http://wiki.videolan.org/VLC_command-line_help if you can't get ffmpeg
working?

Hope one of these solutions works out for you,
~James

Subject: [FFmpeg-user] Syntax problems with different versions of FFmpeg
Message-ID: <CAC0U9k7z4Vy7z0cEKR4Q1_DZmd=ggysGs=XLYWBC7aM85RSuog@mail.gmail.com>

Hi,

I try to apply a command with FFmpeg but I have a problem with
different versions of FFmpeg. The problem comes from the -padleft ...
-padright ... and a version of FFmpeg.
It is reported that the syntax is no longer valid ... but in a more
recent version of FFmpeg syntax in question works, and I'm wondering
...

That's the problem:

A version of FFmpeg under windows:

C:\Documents and Settings\toto1>ffmpeg -i "E:\videos_pour_ekd\machines_sous_esc
lier_divx.avi"  -s 1280x720 -aspect 16:9 -padleft 312 -padright 312 -padbottom

If I put:-vf pad = 0:0:0:0: black ... it works !, why ?

Here the operation under the default version of FFmpeg in Linux Mint 11 RC2:

Syntax:-vf pad ... Is now the syntax by default in all newer versions
of FFmpeg ?

I am looking for a very recent version of ffmpeg for Windows
(ffmpeg.exe) with which the -padlef n -padright n ... -padcolor
hexadecimal ... working properly, can you help me ?

Hi Pyprog

-padleft etc. options are deprecated
Use -vf pad=width:height:x:y:color as in libav doc found here:
http://ffmpeg.org/libavfilter.html#SEC39

Check the documentation; yes it's not maintained well but even it says that
the -padetc. options are deprecated :P

Hope this helps,
~James

I still have to install the libfreetype, but that's for next week. I'm busy 
with other things this weekend. :)

Thanks for your support!

Thanks for your answer, it helped me. I found a part of the solution
(but I have another question, see below).

That's what I do: in fact the source video is 384x320 (bands will be
208 pixels on the left side and 208 pixels on the right side, I want
the video final in 1280x720 [with the bands], the video will be
resized to 864x720 before):

... -s 864x720 -aspect 16:9 -vf pad=1280:720:208:0:blue ...

... but how to ensure that the color bands is defined by hex color or
rgb color ? (with the syntax: -padcolor hexColor it was nice !).

In fact it's a feature I added in EKD (EnKoDeur Mixer) software that I
created in late 2004 and I develop.

In relation to this, see this (sorry it's in French):

http://ekdm.wordpress.com/2011/08/07/possibilites-etendues-pour-le-filtre-video-ajout-de-bandes-exterieures

... the interface is defined by spin colors ... that's why the old
syntax with a hexadecimal color was convenient.

Sorry, I misread again. All that is fine. I just tried and it works well.

Subject: [FFmpeg-user] Subtitle stream added to QT MOV format even when -sn
	switch used
Message-ID: <CAPJStxCJeu5KJCbbrYtLEy8VJByiJctjh6OYN86u=5Uz2na6FA@mail.gmail.com>

Hi,

Apologies if this has been posted/solved elsewhere? I searched and did
not find this particular issue.  Also, I tried to post this last night
and it did not seem to go through -- sorry if this is a double-post.

I am using FFMPEG to encode from an Matroska video (mkv) to a
Quicktime mov file.  Problem is that mov file includes subtitle stream
even when -sn switch is used.  This occurs with both the Fedora 12
current packaged binary (ffmpeg-0.7-45_rc1.fc12.x86_64) and with a
build from GIT source (about one month old).  It also happens when
using the MacPorts FFMPEG.  This does not seem to be a problem when
converting from other file formats to mov (e.g. m2ts to mov)

Here is a little example using the precompiled binary Fedora package.
The second time I run ffmpeg the subtitle stream appears even though
conversion was run with -sn the first time.

Any help or suggestions would be much appreciated.

Thanks!
Evan

Not sure what and why, but does the metadata (aka text aka subtitle stream) 
bother you?
(i mean, does it show on playback?)
If so, can't you get rid of it in the second pass with mapping? (it appears 
as a seperate stream...)
(or perhaps map the first pass, or pipe the second pass...)

Thanks for the response!

It mainly bothers me because it makes it so that Quicktime cannot
manipulate the file.  So I cannot save the file from Quicktime nor can
I use other programs like iFlicks (which I think uses Quicktime API)
when the subtitle stream is present.  On other converted mov
containers (without subtitle stream) iFlicks and Quicktime work fine.

I tried that... running on the mov file again with -vocdec copy
-acodec copy -sn -f mov ... does not get rid of the subtitle stream.
It stays there and I cannot get rid of it no matter what I have tried.
 Any suggestions on how to trick ffmpeg into removing the stream would
be great!

This i don't understand.
A subtitle track should be a custom formatted text file pasted in QT,
has nothing to do with Quicktime being able to manipulate the file or not.
(actually, QT player can be used to strip the track...)
No idea about QT on Linux though, but this is the case on Win and Mac.

Well, did you try -map instead of -sn ?

Thanks again for helping with this.

If I had to guess (and this is a 100% guess) I would say that there is
not actually a subtitle
track there at all -- instead maybe something in the mov container
header (is there such a thing)
that incorrectly marks an additional subtitle track when converting
from mkv file?  Then maybe
when QT reads the file it sees the incorrect header and does not
manipulate file correctly -- this
is just a pure guess though -- I am curious if you do a conversion
from mkv to mov whether you
get this same outcome?

No - does not show on playback (grayed out in QT Player)

Yes - happens equally if I use -map 0:0 -map 0:1 ... here is the
result of running on the test.mov file that I used in
my original post -- second run shows that subtitle track is still there...

Subject: [FFmpeg-user] aac update question
Message-ID: <FC6B8FF2-347B-42DE-9F20-DDB35535EB74@gmail.com>

Hi,

I've been using the experimental aac encoder and it gives pretty good results most of the time, but there are still times where it produces a "tinny" sound or creates background noise.  So my question would be what is the latest regarding development of the aac encoder?  Is it still ongoing and should I expect that with each FFmpeg release it's getting better?  Just curious where it stands thanks!

Message-ID: <loom.20110815T044915-506@post.gmane.org>

i'm comparing ffmpeg with official mpeg2 tm5 implementations and i?m getting
some differences in PSNR measurement (tm5 indicades 4 to 5 dB less than ffmpeg).
Is there some explanation for this? A post or pre-processing perhaps?

Any thoughts would be helpful.

Subject: [FFmpeg-user] extracting a subclip,
	-ss and -t options do not work as expected
Message-ID: <4E4922DF.9090109@hff-potsdam.de>

Hello,

I want to trim a video via ffmpeg cli.
First obstacle, I detected was the order of parameters. Now I place -ss 
and -t before the -i option and get a valid output at least. This output 
still is not the subclip, i want to extract from the input file.

I got a recent build of ffmpeg -> ffmpeg -version:
ffmpeg N-31774-g6c4e9ca
libavutil    51. 11. 1 / 51. 11. 1
libavcodec   53.  9. 1 / 53.  9. 1
libavformat  53.  6. 0 / 53.  6. 0
libavdevice  53.  2. 0 / 53.  2. 0
libavfilter   2. 28. 0 /  2. 28. 0
libswscale    2.  0. 0 /  2.  0. 0
libpostproc  51.  2. 0 / 51.  2. 0

The input is a 10 seconds video h264, created with ffmpeg via:
ffmpeg -i original.mov -y -r 25 -vcodec libx264 -s 640x360 -sameq 
-maxrate 1500k -bufsize 500k first_transcode.mp4

following calls produce results:

ffmpeg.exe -ss 5 -t 2 -i first_transcode.mp4 -y -vcodec copy -acodec 
copy first_trimmed_5_2.mp4
-> 7 seconds subclip, starting from 00:00:00 of the input-clip
ffmpeg.exe -ss 00:00:05.000 -t 00:00:02.000 -i first_transcode.mp4 -y 
-vcodec copy -acodec copy first_trimmed_5_2.mp4
-> same result
When playing around with numbers, the result seems to be more like: -ss 
0 -t (ss+t). This even works, if the values for -ss are negative (-ss -6 
-t 8 returns a 2sec clip, starting from 0 of the input file)

Without -ss, the -t option seems to work fine, but i have no option to 
trim the first part of the clip. I'm looking for a sollution to 
precisely trim my clips via ffmpeg CLI for a while now but don't get it 
working. Any help would be greatly apreciated. I didn't find information 
regarding known bugs or useful examples for CLI usage yet.

Best Regards
Michael

Trimming is done at key-frame/I-frame point. The standard parameter for 
distance between key-frames/GOP-size is 250 if used with x264 as 
encoding codec. So if the source is 10 seconds at a framerate of 25 per 
sec. then there will be only 1 key-frame, the 1st frame.
If you want frame exact trimming, your source has to be a key-frame-only 
file, gop-size=1

Subject: [FFmpeg-user] optimal slide encoding for low bandwidth at youtube
Message-ID: <CAGvH1jBzk2csq1eJOVECi17jnwM2bgmbEdQdt9bv3xXZ+9cTBg@mail.gmail.com>

i want to combine 1 slide ( vid ) and a 3gpp ( audio ) in output that is
suitable for youtube upload. i have a CLI expression working for ffmpeg ,
but its video bandwidth is too high considering that i am muxing just a
single jpeg.

i have used the following , but think that i can do better on the bandwidth
of the VIDEO track...

*./ffmpeg -y -loop_input -f image2 -shortest -r 1/2 -i 1459.JPG -i 1459.3gpp
-s 640x480 -b 100k -bt 240k -vcodec msmpeg4 -acodec libmp3lame -ab 64k -ar
22050  out.wmv*

Once the output from the above is uploaded to youtube, youtube exposes 2
RTSP URI's  - a high and low bandwidth version of the video.

the low bandwidth youtube version still has 39K of video bandwidth and that
is what i want to reduce.... its just a single slide in the video

The input is a 10 seconds video h264, created with ffmpeg via:
ffmpeg -i original.mov -y -r 25 -vcodec libx264 -s 640x360 -sameq 
-maxrate 1500k -bufsize 500k first_transcode.mp4

following calls produce results:

ffmpeg.exe -ss 5 -t 2 -i first_transcode.mp4 -y -vcodec copy -acodec 
copy first_trimmed_5_2.mp4
-> 7 seconds subclip, starting from 00:00:00 of the input-clip
ffmpeg.exe -ss 00:00:05.000 -t 00:00:02.000 -i first_transcode.mp4 -y 
-vcodec copy -acodec copy first_trimmed_5_2.mp4
-> same result
When playing around with numbers, the result seems to be more like: -ss 
0 -t (ss+t). This even works, if the values for -ss are negative (-ss -6 
-t 8 returns a 2sec clip, starting from 0 of the input file)

Without -ss, the -t option seems to work fine, but i have no option to 
trim the first part of the clip. I'm looking for a sollution to 
precisely trim my clips via ffmpeg CLI for a while now but don't get it 
working. Any help would be greatly apreciated. I didn't find information 
regarding known bugs or useful examples for CLI usage yet.

Best Regards
Michael

Subject: [FFmpeg-user] Quantizer Matrix
Message-ID: <4E49ED90.3030208@acolyte-color.com>

Sorry if this is answered somewhere; I checked the man page, all the 
online documentation I could, and this list back to the Big Scism of 
2011....

How do I get ffmpeg to use the MPEG quantizer? When use mediainfo to 
examine a video encoded using the xvid video coder (-vcodec libxvid) or 
the asp default (-acodec mpeg4), it tells me (among many other things) 
that the h.263 "matrix" was used; see below (sorry if this should go 
into pastebin instead).

Assuming the mediainfo tool is correct, is there any way to specify the 
quantization method, such as to employ the MPEG matrices?

Thank you!

Hi.

I'm newbie for ffmpeg.
Recently, I'm trying to build the latest ffmpeg(0.8.2) using arm cross
compile tool chain.
Unfortunately, I met the below build error. (The result was same with

It seems like that gcc can't recognize some arm instruction. Is it right?

Hi
I compiled the the latest version of FFMPEG (ffmpeg-0.8.2). In the
configuration file i enabled the 'avisynth'(--enable-avisynth). But when i
issued the 'make' command the output showed like the following
libavformat/avisynth.c:124: undefined reference to 'ff_codec_tags'.
libavformat/avisynth.c:124: undefined reference to 'ff_wav_c_get_id'.
make: ***[libavformat/avformat-53.dill] Error 1

What is the solution for this probelm?
if anyone knows Kindly help me...

Thanks & Regards

Subject: [FFmpeg-user] libavfilter: setsar works consistently with libx264!
Message-ID: <20110816105624.GQ653@krille.blacktrash.org>

Hi,

Just a heads up that as of ffmpeg N-31898-g95b5b52 (or a few
commits before) libavfilter's setsar with scale and even crop
seems to work consistently when transcoding e.g. from pal
sources. Before, the behaviour differed haphazardly from other
target codecs - i.e. you needed setdar too, or couldn't get a
correct result at all.

So, do not change it ;-)

Hey Robert,

A few suggestions:
1) what may be killing you are the intra frames. What size is your jpg? Also
look into making your GOP size as large as possible maybe? this is done by
using option -g 'gop_size'
2) is there a specific reason you are using wmv? In my usage I've found
libx264 to compress the most efficiently, and i'm fairly certain that
youtube accepts .mp4 upload. (-vcodec libx264 -acodec aac -strict
experimental)
3) not sure how low frame rate can go, but try dropping it more? maybe
1/(song_length_in_seconds) would work?
4) your -b option is at 100k.... try dropping to your real target? Same with
-bt

None of these are tested, just ideas. Hope one of them helps.

Subject: [FFmpeg-user] Newbie question: Can FFMPEG grab frames from webcam?
Message-ID: <CAHT7zqtnVaD5mDFmqp77yNs9mZJV9aUc+bYWe1HShBKujVD5Lw@mail.gmail.com>

Hello.  Looking for some guidance. Thanks in advance for your time...

I currently use ffmpeg to assemble still images into movies.  I have
developed a 16mm film scanner, based on a projector, that gathers frames,
similar to this project, which was the inspiration to my machine.  (
http://hackaday.com/2011/01/15/converting-8mm-film-to-digital/) I am using a
webcam (Microsoft LifeCam) in front of the projector lens. As each frame
advances, the projector "clicks" an embedded mouse, taking a high res jpg
image, utilizing the (gag) Microsoft lifecam software that the camera came
with.  I then use irfanview to crop/flip/renumber the images, and ffmpeg to
assemble them into the movie. The trouble is...the Microsoft Lifecam
Software has a memory leak, and after about 5000 frames (about 2 hours), the
software chokes.  So, I'm rethinking the workflow.  Can FFMPEG be used to
grab frames from a webcam with a mouse click?

Hey Eric,

Assuming video for windows drivers, some research turns up a few bits of
commands that may work. I have no experience in this, but here's something I
would try running:

ffmpeg -f vfwcap -i 0 -vcodec mjpeg -vf 1 -an output.jpg

0 is the default device, captured from vfw driver. I think this should give
you a jpg of the image currently seen by the webcam. -vf 1 will make sure
ffmpeg will only process for 1 frame.

As for "running on a click" you can set up a batch script that increments
the file name in a loop, and have a pause after each image capture that is
released into the loop again when you 'press any key to continue'

Hope this helps.

Subject: [FFmpeg-user] converting Quicktime files with multiple audio tracks.
Message-ID: <CA6FF95B.163E8%glau.stuff@ridiculousprods.com>

Hi, occasionally I get a file that has multiple audio sound tracks in it.
(not to be confused with channels).

It might be a quicktime file with two separate stereo tracks. (Track 1
L/R; Track 2 L/R) or a file with two mono aac tracks.

Some Skype phone recorders in particular seem to generate files that are
one distinct mono track for each end of the conversation instead of one
stereo track split L/R

Let's assume I have the following:

Quicktime MOV file with

* Track 1 - Mono
* Track 2 - Mono.


How do I export this to mp3 such that both tracks are represented on the
MP3 file. Either Track 1 to Left Chanel, Track 2 to Right channel; or
Track 1 & 2 merged into a mono MP3 file

I suspect it has to do with the -map feature, but a concrete example would
help a lot.

Thanks.

Hey Glau,

I don't believe ffmpeg has the capability to map to channels. AFAIK, -map
only maps different streams. I expect that when libavfilter gets audio
filters that this will be among its most basic features.

Open programs I suggest to do what you are looking for:
Sox: http://sox.sourceforge.net/
Similar to ffmpeg in command line complexity
Audacity: http://audacity.sourceforge.net/
GUI audio manipulation tool

Hope this helps,
~James

Pavel,

Have you tried ffmpeg -f rstp -i rstp://link -f alsa -i hw:0,0 -f flv
"rtmp://link"
Adding more options on the output such as the vcodec and acodec may help.

Hope this helps.

SOX doesn't seem to handle MOV files as a source input. Error Message:

sox FAIL formats: no handler for file extension `mov'

We had been getting around this problem with the exception of the
multi-track issue by using the following chain on the command line. (only
command line options are usable as this is part of a server solution)

* ffmpeg -i original.mov temp.wav 			(This converts our source file to
generic WAV)
* sox 'temp.wav' 'sox_temp.wav' highpass -2 150 	(roll off some bass on
all files)
* ffmpeg -y -i 'sox_temp.wav' -vn -acodec libmpelame -ac 2 -ar 22050 -ab
80Kk 'final.mp3' (make the final MP3)

Since ffmpeg recognizes and can open more formats than sox, specifically
MOV and AAC files, we use that as the first step to create a generic WAV.
>From there we manipulate the WAV in sox and finally create our final low
bandwidth MP3. This works fine except with the multi-track issues.

ffmpeg (using the commands I'm familiar with) will only convert the first
"Track" it sees and ignores any secondary tracks.

Here's the output from a sample file just using "ffmpeg -i sample.mov".
I've omitted the non-relevant output.

> ffmpeg -i sample.mov

	Stream #0.1(eng): Audio: aac, 44100 Hz, mono, s16, 31 kb/s

As you can see from the output, ffmpeg has found two "Tracks":  Stream
#0.0 and #0.1

When using our chain listed above, we end up with a MP3 that only contains
the audio for Stream #0.0

Right now we're having to download this edge case files and convert them
on the desktop and reupload them to the server. Not a super great
solution... :(

Hm, I think you can extract 2 different streams as 2 different files.
namely:
* ffmpeg -i original.mov -map 0:1 -vn -ac 1 temp1.wav
* ffmpeg -i original.mov -map 0:2 -vn -ac 1 temp2.wav
* sox -m 'temp1.wav' 'temp2.wav' -c 2 'sox_temp.wav' highpass -2 15
* ffmpeg -y -i 'sox_temp.wav' -vn -acodec libmpelame -ac 2 -ar 22050 -ab
80Kk 'final.mp3'

Never used sox before, so no guarantee this works at all haha, maybe I'll
get lucky?
Basically what I changed is that instead of keeping the 2 streams in one
file, I mapped the streams and then mixed them in sox using -m (-M *should*
produce something different but I don't know how different in this case).

Hope this helps,
~James

Message-ID: <CAH7nJRUJJiR_eS=txgeK1rNQgLj0tsZFQrs9rB=UMiGUJuYWkQ@mail.gmail.com>

Hi everyone, First time posting on this list.

The short version:

#ffmpeg -i rtsp://www.address.com/Auto%20DJ%20Channel%202?tcp test.wav
...
[rtsp @ 003AA3E0] Failed to fix invalid RTSP-MS/ASF min_pktsize

The long version:

I am setting up an application to switch between different incoming
audio streams for a single output.
As part of this project I am using ffmpeg to decode the incoming data
to wav format.
I have it connecting to the Auto DJ over rtsp however it sometimes
fails with the below error (and the freeze) and sometimes appears to
freeze with no error at all:

[rtsp @ 003AA3E0] Failed to fix invalid RTSP-MS/ASF min_pktsize

No data is written to the output.

The Auto DJ server is basically just a Windows media services 9.6
Server with a play list.
Each time you connect it picks a (random?) file from its playlist and
streams it to the client (ffmpeg).

The odd thing is we have 2 such servers with different play lists. One
will fail 1 time in 10, the other more like 9 times in 10 (these are
guesstimates).

Connecting to the same server using winamp (over mms, although I
belive this is the same thing?) works first time every time.

I am thinking this must be some kind of incompatibility between ffmpeg
and Windows media services 9.6 ?

I get the exact same behaviour whether I try it on Windows 7 or SUSE
11.4 on a different PC (the Hex number is different every time though)

Full transcript of a failed run below if it helps

Can anyone shed any light?


Many Thanks

Lee

Message-ID: <CANY4w8D400xBJOHDvaH-bS6SCxXUfoLBHe3NVC2RHwVkHVYjZA@mail.gmail.com>

Hi. I'm trying to record a screencast with ffmpeg and record my pc audio,
and my microphone. Recording only one stream works fine, but when I try to
record with two pulse inputs, I get no audio in the resulting video (I
changed one of the pulse inputs with pavucontrol to use the pc audio instead

ffmpeg -f x11grab -r 15 -s 1366x768 -i :0.0 -f alsa -ac 2 -i pulse -f alsa
-ac 1 -i pulse -vcodec libx264 -acodec pcm_s16le -vpre lossless_ultrafast
-threads 2 output.mp4

I should also say that whenever I use the input hw:0,0 or something similar,
when I play back the resulting video, the audio seems to get gradually out
of sync. Can anyone help?

Message-ID: <87r54kkkwq.fsf@Compaq.site>

I want to convert my video's for YouTube. At the moment I am using:
    ffmpeg -i input.MOV -ar 22050 -acodec libmp3lame -ab 32k -r 25 -vcodec flv -s vga -qscale 2.5 output.flv

This seems to work, but still gives quit big files. 35 MB for 1:48.
Input file is 89 MB.

So I was wondering: is there a better way?

For youtube one normally only preprocess.
De-interlace, crop and set correct aspect ratio.
Youtube will always recompress, so introducing compression artefacts is a 
big no-no.
IOW, upload the biggest file your bandwith allows.

Subject: [FFmpeg-user] Can't combine 2 pulse input streams in screencast
Message-ID: <201108172159.15427.hoot893@gmail.com>

Hi. I'm trying to record a screencast with ffmpeg and record my pc audio, and 
my microphone. Recording only one stream works fine, but when I try to record 
with two pulse inputs, I get no audio in the resulting video (I changed one of 
the pulse inputs with pavucontrol to use the pc audio instead of the 
microphone). Here's the command that I use:
 
ffmpeg -f x11grab -r 15 -s 1366x768 -i :0.0 -f alsa -ac 2 -i pulse -f alsa -ac 
1 -i pulse -vcodec libx264 -acodec pcm_s16le -vpre lossless_ultrafast -threads 
2 output.mp4

I should also say that whenever I use the input hw:0,0 or something similar, 
when I play back the resulting video, the audio seems to get gradually out of 
sync. Can anyone help?

Hi?

I am doing some experiment to check how ffmpeg/x264 react to packet or slice drop in h264 video streams. I already experimented with several sets of parameters to compare ffmpeg with JM. Can anyone tell me or help me to find out that how I can drop slices in ffmpeg/x264? I really appreciate any kind of help. Thanks

I tried out VLC directshow capture mode. It is working fine. But using VLC's
dirctshow mode we can't do RTMP streaming.
I need to stream webcam video to a Flash media server using dshow.
If have any idea please reply me..
Thanks in advance..

thanks for how to instructions on libx264.  i got good result on mp4
produced by ffmpeg with very low video bandwidth using :

./ffmpeg -y -loop_input -shortest -i  Optimized-DSC01448.JPG -i
rec_1448.3gpp  -pass 1 -vframes 500 -vcodec libx264 -r 1/100 -vf

+parti8x8+parti4x4+partp8x8+partp4x4+partb8x8 -acodec libmp3lame -ac 1 -ar
22050 -ab 22k _my.mp4


i think that the issue is at youtube because i was able to use the
instructions for libx264 to create an mp4 combining a single slide and a
voice track in which , mplayer reports the bandwidth on the video track as
1.8 kbps.

After uploading that mp4 to youtube and after the resultant transcoding and
processing of the youtube distribution platform, the Video track bandwidth
had risen from 1.8kbps to 24 kbps.

details on youtube process ( mp4 stats on mplayer, SDP for the youtube RTSP
feed ... )
    see: http://goo.gl/W0Dg8

not alot that i can do about that ..  thank you for all the help

Removed in April git has now added 3 new options for libx264 encoding:
-preset <preset>
-tune <tune>
-profile <profile>

These options are directly mapped to internal tune and presets within
libx264. The old presets files have been removed, please use the new
options.

Such as:
-profile baseline

See "x264 --help" to see available presets, tunes, and profiles

Maybe ask the VLC people?

Did you look at this? does it work?
According to http://ffmpeg.zeranoe.com/forum/viewtopic.php?f=3&t=27&start=10
(last post) it should "just work" though I haven't tried it myself,
and apparently it isn't easy...

Can you disable all cacheing? That might help...

You may be interested in some experiments I did when I was trying to make a 
video slideshow with FFmpeg. I was offended by the obvious wasted data when 
using other methods. I understand this is somewhat different from your issue, 
because you only have one slide.

I posted my experiences here:
<http://sites.google.com/site/andycivil/making-a-video-slideshow-with-ffmpeg>

Basically, I use MPEG-2 as an intermediate format; it's not efficient, but it 
has the outstanding advantage that I can concatenate the video slides in a 
command window, and then convert and add a soundtrack afterwards.

I also recently discovered that I can convert to H.264 and it stays pretty 
efficient, although the file is larger.

I find that if I upload the video to youtube, it is accepted, but when I 
download it again it's a bit bigger. I think the issue is that they have 
standards for rewinding resolution, so their GOP is lower than I actually had in 
my file; therefore, they probably duplicated the i-frame, perhaps once per 
second or something.

The dpi header value just suggests a default presentation size and should not bother you at all. 72dpi means : spread 720px to 10 inches screen width. 96dpi just results in 7.5". But both images are 720 pixel wide.
Use Irfanview or other tools to alter just this header detail later.

Hello,

Hope my words find you all well.

I need your help in a matter that I can't find a solution through searching
on fixes for it.

I'm on an iMac 3.4GHz i3, 4GB of RAM, and x86_64 arch, and I'm trying to

I'm using the following command (includes all info about source and output)

I bolded the aspect that I needed since from source it is 4:3, and I have a
LED screen with 16:9 with apple TV 2.

My problem is that, opening the output file through VLC, it opens with 16:9
aspect ratio, but in iTunes (which reflects Apple TV 2) it opens with 4:3
aspect ratio, please tell me if I'm missing any other option for ffmpeg and
recognized by iTunes / Apple TV 2 that would convert the video with 16:9
aspect ratio.

Regards, Tony.

P.S: please don't tell me to use any application such as hand break or
something, they all use ffmpeg and they output the same as my ffmpeg CMD,
but much slower (UI complicated also when you get into advanced options).

Now you just use the same preset for both passes for most cases.
Example:

ffmpeg -i input -pass 1 -vcodec libx264 -preset fast -b 512k \
-threads 0 -f mp4 -an -y /dev/null && \
ffmpeg -i input -pass 2 -vcodec libx264 -preset fast -b 512k \
-threads 0 -acodec libfaac -ab 128k -ac 2 output.mp4

Thanks for the Reply,

ya....I tried out that.
In my compiled version of ffmpeg there is no dshow format.
So that example didn't worked.

Thanks and Regards

Subject: [FFmpeg-user] Several issues encoding DV* video
Message-ID: <4E4E4FBE.6020303@vizrt.com>

I'm trying to generate video in DV25, DVCPro25, DVCPro50 (and ideally 
also DVCPro 100, but I know this is not possible).  I'd like to have 
them as both raw DV files and wrapped in MXF, but have problems getting 
the correct encoders.  In short I do not know how to get DV25 with audio 
in DV and MXF wrappers and DVCPro25 in MXF wrapper.

These are the results I get when testing different combinations:

DV25

ffmpeg -i input.y4m -s 720x576 -r 25 -pix_fmt yuv420p output.dv

generates a DV file.  No problem.  But then I try to add the audio tracks:

ffmpeg -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv420p output.dv

generates what mediainfo reports as a DVCPRO file, though the chroma is 
4:2:0.

The same thing happens if I wrap as MXF:

ffmpeg -i input.y4m -s 720x576 -r 25 -pix_fmt yuv420p -target dv output.mxf

generates DV and

ffmpeg -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv420p -target dv output.mxf

generates DVCPRO.

DVCPro25

ffmpeg -i input.y4m -s 720x576 -r 25 -pix_fmt yuv411p output.dv

generates a DVCPro25 file.  No problem.

ffmpeg -i input.y4m -s 720x576 -r 25 -pix_fmt yuv411p output.mxf

generates MPEG-2 in MXF wrapper, whereas

ffmpeg -i input.y4m -s 720x576 -r 25 -pix_fmt yuv411p -target dv output.mxf

generates DV with 4:2:0 subsampling.  Not what I wanted.

Now, trying to add the audio tracks:

ffmpeg -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv411p output.dv

gives the error message

"[dv @ 0x28e3960] Can't initialize DV format!
Make sure that you supply exactly two streams:
      video: 25fps or 29.97fps, audio: 2ch/48kHz/PCM
      (50Mbps allows an optional second audio stream)"

How come ffmpeg managed to take the two audio files earlier and combine 
them in one stereo stream in the output?  I need to map the audio 
channels; this cannot be done in ffmpeg, as far as I have been able to 
figure out, but ffmbc lets me do this:

ffmbc -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv411p output.dv -map_audio_channel 1:0:0:0:1:0 -map_audio_channel 
2:0:0:0:1:1

This works and gives me DVCPro25 output.  But, now attempting to wrap in 
MXF:

ffmbc -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv411p -target dv output.mxf -map_audio_channel 1:0:0:0:1:0 
-map_audio_channel 2:0:0:0:1:1

generates something marked as DVCPRO, but with 4:2:0 subsampling.

DVCPro50

ffmpeg -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv422p output.dv

generates the same error as before.

ffmpeg -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv422p -target dv50 output.dv

generates DVCPro50 output, with two stereo streams in the output file.

ffmpeg -i input.y4m -i left.flac -i right.flac -s 720x576 -r 25 -pix_fmt 
yuv422p -target dv50 output.mxf

also generates the expected output.

Hi Eric;

I really enjoyed reading your post! there are so many things that
ffmpeg can do that many of us who use it, take for granted.

I have used this command for turning single frames to movies:

ffmpeg -f image2 -i img%03d.jpeg /tmp/a.mpg

However the concept that you have written about & demonsrated is very
interesting!

Thanks,

MJ

I would guess that this is a damaged input file. What is your ffmpeg
command? Are you using a recent ffmpeg from Git or some ancient version?

Message-ID: <CAHT7zqumEic87-Yu0b+knYvaN_pGOnaqHr1QEiPH=HfpwfwP8w@mail.gmail.com>

Hello.  Looking for some additional guidance. Thanks in advance for
looking...

The command line below, when run on my Win 7 Pro 32 bit, Core2 Duo E8400
@3.0Ghz, 3G RAM machine, takes 3.86 seconds to write a pic to the disk.  I
have written a script that calls this command line each time a frame
advances on my film scanner. I was hoping for an execute time of 1 to 2
seconds, since I am digitizing hundreds of thousands (probably millions) of
frames of film.  Any suggestions on how this could be made to run faster?

     ffmpeg.exe -r 1 -rtbufsize 100000000 -f vfwcap -s hd720 -i 0 -vframes 1
-vf crop=943:686:180:3,hflip test.tif

At this point, I'm willing to entertain switching platforms to Linux, and
dedicating a machine to this process. Ideas welcome.

Thanks again for the help I've received from this group over the past couple
of days!

Eric

(Short description of project)
8/17/11
I currently use ffmpeg to assemble still images into movies.  I have
developed a 16mm film scanner, based on a projector, that gathers frames,
similar to this project, which was the inspiration to my machine.  (
http://hackaday.com/2011/01/15/converting-8mm-film-to-digital/) I am using a
webcam (Microsoft LifeCam) in front of the projector lens. As each frame
advances, the projector "clicks" an embedded mouse, taking a high res jpg
image, utilizing the (gag) Microsoft lifecam software that the camera came
with.  I then use irfanview to crop/flip/renumber the images, and ffmpeg to
assemble them into the movie. The trouble is...the Microsoft Lifecam
Software has a memory leak, and after about 5000 frames (about 2 hours), the
software chokes.  So, I'm rethinking the workflow.
8/19/11
I have now gotten the command line above to grab the frame and save it as a
much-preferred uncompressed tif, replacing the Microsoft LifeCam software
and the Irfanview crop/flip stage.  Now all I need to do is finish the
script that will invoke this command each time the projector sends a "left
click".  The projector can be slowed to ~ 2.5 seconds between frames, but
ideally, it should run in the 1 second per frame range.

Hi everyone, First time posting on this list.

The short version:

#ffmpeg -i rtsp://www.address.com/Auto%20DJ%20Channel%202?tcp test.wav
...
[rtsp @ 003AA3E0] Failed to fix invalid RTSP-MS/ASF min_pktsize

The long version:

I am setting up an application to switch between different incoming
audio streams for a single output.
As part of this project I am using ffmpeg to decode the incoming data
to wav format.
I have it connecting to the Auto DJ over rtsp however it sometimes
fails with the below error (and the freeze) and sometimes appears to
freeze with no error at all:

[rtsp @ 003AA3E0] Failed to fix invalid RTSP-MS/ASF min_pktsize

No data is written to the output.

The Auto DJ server is basically just a Windows media services 9.6
Server with a play list.
Each time you connect it picks a (random?) file from its playlist and
streams it to the client (ffmpeg).

The odd thing is we have 2 such servers with different play lists. One
will fail 1 time in 10, the other more like 9 times in 10 (these are
guesstimates).

Connecting to the same server using winamp (over mms, although I
belive this is the same thing?) works first time every time.

I am thinking this must be some kind of incompatibility between ffmpeg
and Windows media services 9.6 ?

I get the exact same behaviour whether I try it on Windows 7 or SUSE
11.4 on a different PC (the Hex number is different every time though)

Full transcript of a failed run below if it helps

Can anyone shed any light?


Many Thanks

Lee

Currently you can overlay a video on top of another, in a static
position. I suppose overlay could be extended by making x/y depending
on time, but currently not yet possible. Patches/feature requests are
welcome.

Audio filtering is a work in progress, and will hopefully land soon,
right now not yet possible.

I understood that when you preprocess you do not have the risk that
YouTube converts wrongly.

Today I made a 3? minute video. This was 169 MB big and took almost an
hour to upload. The converted (24 MB) took 8 minutes. So I think I'll
keep converting. It looked okay, but if someone has better parameters?

where are you living that 169 MB upload takes an hour? :-)
10 MBit up are priced with < 100,- per month abd valueable if needed

on the other hand - who interests that hour ONCE for upload
while quality is degraded for thousands of users if you crap the
input file before the upload?

The Netherlands, but with ADSL your download is fast, but your upload
less.

I do not see a difference between the full upload and the converted one.

But perhaps others do...
(it's an art to spot these things...)

Nice trick to test, rip both, apply a difference matte on the two clips.
If you see something else than pure black, there sure is a difference, and 
those are the spots you need to carefully check.

You have a point there.

I have been googling, but I can not find how to do that (the
difference matte, ripping is not a problem). How to do that?

I'm not the OP, but I'm interested but not familiar with the terminology.  Can 
you give a few more clues as to what you mean by:
   * rip (what do you rip, what command could you use)
   * apply a difference matte (what command could you use)

Thanks!

Several tools around to get the video from youtube in it's orignal form.
Do a google search on 'rip youtube'
a Matte is a key signal. Normally black and white.
A Difference matte is comparing two streams by subtracting each pixel's 
value.
If the pixels are the same, the result is of course pure black.
So it generates a stream where differences between the two streams is shown 
in a black and white image,
used for special effects, or, in this case, quality control.

Probably there is an Avisynth filter, but most NLE's / special fx packages 
have something like that.
(after effects for sure).
So it depends on the tools you have....

Message-ID: <F384B10E-B5BD-4F2B-8EB7-FCF6F2FF922D@frey.co.nz>

Hi all,

I'm trying to convert a number of AVCHD 1080i 50fps videos from a Canon HF G10 to mp4/mov container format, but ffmpeg is failing with a 'non monotonically increasing dts' error message at the start of each one. I'm on Mac OSX 10.6, I've tried both ffmpeg 0.8.0 (compiled by Homebrew) and 0.8.2 (compiled by ./configure && make).

Here's the commandline. The file is here: http://frey.co.nz/share/00167.MTS (2.2MB)

$ ffmpeg -i 00167.MTS -vcodec copy -acodec copy out/00167.mp4

Output fails with:

What's going on here? Is my camera really putting out such scrambled timestamps? Is there anything I can do about it?

Any help appreciated.

Cheers,
Damian

I am using ffmpeg. I am generating images out of a ts video file. But my observation says that ffmpeg gives some gray color images initially and after some gray images , actual video images are getting generated.

How can I give command to ffmpeg that it directly generate actual video images.

I will be very much thankful to you if you kindly answer for my above queries.

Thanks.

Output stream is H264, AAC using x264 and faac

Im playing with a segmenter and cutting the streams on an AV_PKT_FLAG_KEY, but what im seeing is a cut where the 1st frame does not start with sps/pps,

How do i find the correct key frame to split the stream?. Is there a flag returned i can use.

Subject: [FFmpeg-user] ac3 invalid bit rate error
Message-ID: <C77ABA64-A232-43E7-9817-C9D528666EED@gmail.com>

Have been converting dts audio to ac3 successfully with ffmpeg for almost a year.  Built a new ffmpeg executable today (ffmpeg version N-32060-g124deea) on Mac Pro running 10.7.1 and now get the following error when attempting to convert:

[ac3 @ 0x7fbe9b02f400] invalid bit rate

Error while opening encoder for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height

I am also seeing:
[mpegts @ 0x7fbe9b008800] Continuity Check Failed

The conversion process does not seem to be hanging up on the continuity check but is hanging up on the ac3 error but maybe they are related.

Configure:
./configure --prefix=${TARGET} --cc=clang --enable-nonfree --enable-gpl --enable-version3 --enable-libx264 --enable-pthreads --enable-libfaac --enable-libspeex --enable-libvpx --disable-decoder=libvpx --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libopencore_amrwb --enable-libopencore_amrnb --enable-libgsm --enable-libopenjpeg --enable-libxvid --enable-libschroedinger --enable-libdirac --enable-libxavs --enable-librtmp --enable-libfreetype --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-swscale --enable-avfilter --enable-filters --enable-postproc --target-os=darwin --arch=x86_64 --enable-runtime-cpudetect

My conversion command line has not changed.  The audio portion of command line:
-acodec ac3 -ab 448k -ar 48000

448k is a valid bit rate!!!

Get the same error wether the audio source is dts or ac3.

Any work arounds for this error?  Thanks in advance for help.

I have noticed green frames when playing things sometimes with ffmpeg,
only at the beginning.  Maybe it's waiting for an i-frame and your
stream doesn't have one for a while?

I have experimented a lot with it. One can for example take the sound out

something like it
ffmpeg-i sameq myvideo.avi -acodec copy mysound.wav

so you can run a noise filter in sox or audacity. And then take the
sound back again

something like this.
ffmpeg-i sameq myvideo.avi -vcodec copy -mynewsound.wav -acodec copy
mynewvideo.avi

I will not go into details of what they do in sox and audacity because
I myself have been very disappointed with the result but if you'd like
to try, I will come here to explain it. I sit right now and is about
to do it in a movie where there has been much wind into the
microphone.

Hi All,

I am using FFMPEG for transcoding of  MP4 files.
Could any one pls tell me what all video\audio codec combination are
supported by ffmpeg in MP4 container.
MP4 by definition does not specify the supported audio\video codec list.

Any pointer orhelp on this will help me in moving forward.

Thx in advance.

Hi Raman,

For mp4, I like to use -vcodec libx264 -acodec aac -strict experimental
Generally mp4 accepts most codecs, and will play on any player that has the
correct decoders.

Ok I have just done it so I'll go through the steps I just did it meself.
You must have audacity installed to do this.

I isolate the sound
ffmpeg -sameq -i shoe12.mpg sound12.wav

In audacity
I open audacity and drag the audio file into Audacity. I listen and
find a place on the sound file where there is wind noise. I mark this
place.
So I go in
Effects -> Noise removal
Then comes a dialogue and here I press button
"Get Nois profile"
Then I go back to the track and now I mark the entire track. Now again i do.
Effects -> Noise removal

dialog appears again but this time simply press ok at the bottom of
the box. Then it remove the noise.

Now you need to save.
File -> Export

save (export) as wav

Back to ffmpeg

Now I take the sound of the original video

ffmpeg -i ude.mpg -an -vcodec copy udeuden.mpg

And now I put the new noise reducing sound in instad

ffmpeg -i udeuden.mpg -vcodec copy -i soundreduce.wav new_out.mpg

In this case, I was really pleased with the outcome

That was it. Hope you can follow me, otherwise ask.

The video I used this for, I just put on youtube it lies here. Be
aware that only a small fraction of the total video is noise is
reduced. Only that which takes place outside.

This is a common problem for me. Sometimes this works when ffmpeg fails:

mplayer -nosound -benchmark -vo yuv4mpeg:file=>(x264 --demuxer y4m --crf 
20 --threads auto --output output.264 - 2>x264.log) input.mts

See: https://sites.google.com/site/linuxencoding/x264-encoding-guide

I can't imagine why mplayer (based on ffmpeg) sometimes works when 
ffmpeg doesn't. Sadly, if mplayer doesn't work you're probably out of 
luck. At least in the open-source world.

And yes, it's puzzling why so much AVCHD doesn't work with the open 
source tools.

good luck.

Message-ID: <CA784744.16904%glau.stuff@ridiculousprods.com>

I've got a .raw audio file I'd like to convert to MP3 using ffmpeg. I know
that I could first convert it using sox with something like:

sox -r 44100 -e unsigned -b 8 -c1 test_file.raw test_file.wav

And then use ffmpeg to convert the WAV to MP3.

But I want to skip a sox pass if I can and go straight to MP3.  Is that
possible? I saw mention of raw formats in the documentation but not a set of
commands specific for audio (unless I missed it)

Hi Phil,

ffmpeg is really awesome, it should do any encoding you want. just go ahead
and do what you think you should:

ffmpeg -i input.raw -acodec libmp3 output.mp3

With encoding, you want to put in as many options as you can, so I suggest
using -ab. Check the documentation for more commands

Some tips:
1) use ffmpeg -formats and ffmpeg -codecs to check for which formats and
codecs are available for your build of ffmpeg
2) for audio manipulations, sox and audacity are usually better
alternatives, but ffmpeg has a much larger array of formats available.

Hope this helps,
~James

-acodec libmp3lame

You may have to tell ffmpeg more about the raw input such as:

ffmpeg -f u16le -ar 44100 -ac 1 -i input.raw ...

> With encoding, you want to put in as many options as you can, so I

Often overlooked is -aq instead of -ab. Appropriate values for this
option depend on the encoder. With libmp3lame, this option is
equivalent to the -V option in lame. For a nice chart see:

SoX can be compiled to support MP3 encoding too.

Subject: [FFmpeg-user] Pad filter seems to have no effect
Message-ID: <4E5318B7.80707@davidfavor.com>

Input footage is a Skype recording with two video
tracks which require to be positioned side by side
in the final video.

Looks like the pad + overlay filter is the best way
to do this.

At least one output file must be specified

I've tried pad with all sorts of variations of arguments and codecs,
with no effect.

The command which appears to be correct is:

    ffmpeg -y -i test.skype.mov -an -vf pad=640:480:640:0:white -map 0.2 -vcodec copy test.video.mov

My goal is to just create an output video right padding one
video track by 640 pixels.

Someone let me know where I've gone wrong.

Thanks.

I have noticed green frames when playing things sometimes with ffmpeg,
only at the beginning.? Maybe it's waiting for an i-frame and your
stream doesn't have one for a while?

could you please file a bug report in the bug tracker and supply a very short sample clip with it?

I've had a similar problem in the past and it is buried somewhere in the old roundup bugtracker that I don't know if anyone is using it or if the information is essentially lost. I managed to get this working in my case with a hack in the code by replacing a ">"-Check with ">=" where the error occurred but it might be something else in your case and of course that was not a proper fix but if you want to get your material transcoded, you probably don't really care about that (I didn't). In any case, having this in the bug tracker with a small sample increases chances that someone can/will fix it. Please provide the camera model and recording mode in your bug report so others find this when they run into the same problem.

Cheers,

Robert

Done: 
https://ffmpeg.org/trac/ffmpeg/ticket/415

Could be related: 
http://ffmpeg.org/trac/ffmpeg/ticket/177

FWIW, writing the mp4 stream to an mkv file seems to be working fine, but this is not ideal as the video editing software I'd like to use doesn't natively support mkv.

I have the same problem with the "JVC Everio GZ-HM650". The problem only
occurs when copying the original streams to the new container.

So I get the error (build: N-32023-gf138c7f) with the command from Damian:

ffmpeg -i 00167.MTS -vcodec copy -acodec copy out/00167.mp4

but when transcoding like:

ffmpeg -i 00167.MTS -vcodec libx264 -acodec copy out/00167.mp4

it works. Please let me know the bug submission, so I can add a sample
file, Recording device info and this note if needed.

Regards,

Adruna

Do you mean that you want the output to start from the point where you get  
an I-frame?  That could potentially be a long time in the future -- I've  
had to deal with streams that went several minutes between I-frames.

Yes, I would like ffmpeg should generate frame when it finds first I frame.

If it gives initial gray color frame then it definately means that it did not find I-frame thati s why ffmpeg keeps on inserting dummy frames.

I dont have any idea which command does this removing gray color frames. We need to change something in coding. Where should we change that I am still figuring out. If you have any idea how we should keep on drop the frame till we get I frame then it may solve my purpose.

pad=width:height[:x:y[:color]]

the padded area (specified by width:height) must contain the input
video placed at position 640:0, so it should be:
pad=640+640:480:640:0

I've discovered that ffmbc http://code.google.com/p/ffmbc/ can do this out of the box:

ffmbc -i 00167.MTS -vcodec copy -acodec aac -ab 256k 00167.mp4 

produces an .mp4 that Quicktime is perfectly happy to play. I wonder how easy/difficult it would be to backport ffmbc patches to ffmpeg?

technically this would probably work but ffmbc is GPL whereas the corresponding code in ffmpeg is LGPL, i.e. backporting without the explicit consent of ffmbc's author baptiste to relicense to LGPL would make the ffmpeg code GPL which would be a problem for many people.

Aah, that'd be true..

Already tried your suggestion...

This produces no effect:

    ffmpeg -y -i test.skype.mov -an -vf pad=1280:480:640:0:white -map 0.2 -vcodec copy test.video.mov

Maybe I best bump up to latest, which is probably 0.7.2 or 0.7.3 and retest.

Obviously, you can only apply video filters to the decoded video, but your
command tells ffmpeg not to decode the video.

It may be theoretically possible to add borders without reencoding, provided
the size of the borders is a multiple of the block size of the codec, but
ffmpeg does not have any feature of the sort, and will probably never have.

Updated to ffmpeg-0.7.3 and still no effect.

Neither of these produce any effect:

      ffmpeg -y -i test.skype.mov -an -vf scale=1280:480 -map 0.2 -vcodec copy test.video.mov

      ffmpeg -y -i test.skype.mov -an -vf scale=1280:480,pad=1280:480:640:0:white -map 0.2 -vcodec copy test.video.mov

Maybe the problem is -vcodec copy... although I've tried various
re-encoding schemes with no effect either.

This works...

     ffmpeg -benchmark -y -i 30sec-test.skype.mov -an -vf pad=1280:480:640:0 -map 0.2 \
            -vcodec libx264 -threads 0 -vpre lossless_fast -crf 25 30sec-test.video.mov

And takes a huge amount of time.

Best estimate on an 8x core machine is around 3 minutes encoding time for every
1 minute of video. Ouch.

Got to be a better way to extract the video streams intact.

I'll start a new thread about the problems with simple mapping to copy the video
streams intact.

Thanks.

Subject: [FFmpeg-user] x264 encoding of certain (small) videos take hours
Message-ID: <4E52A8CF.3070106@netomia.dk>

Whenever I try to encode a video file form my Android phone with x264, 
it takes several hours - as compared to seconds with other videos of the 
same length and size.

Does anyone know of a fix?

:::: My goal is to copy both video streams without any change.

This command comes close:

            -vcodec copy -vcodec copy 30sec-test.video.mov -newvideo

Except the second stream in the output video has changed codecs...

Hi, getting x264 from git and ffmpeg by svn - both newest versions. By starting ./configure with -enable-libx264 I only get following error:

 

ERROR: libx264 version must be >= 0.99.

 

Is there any work around out there to solve this problem?

FFmpeg uses Git instead of SVN now. The last revision to the FFmpeg SVN
repository was on 2011-01-19, so try using more recent source from Git.

Message-ID: <DC59839E-A2A4-458E-AD4C-C59D77170C9C@gmail.com>

Hi again,

I have asked in the past about hard-coding subtitles, but if I just want to add a subtitle track as a stream would someone mind giving me a working example?  I'm aware of the documentation which says this:

ffmpeg -i file.mov -an -vn -sbsf mov2textsub -scodec copy -f rawvideo sub.txt

And in FFmpeg -formats it says it supports decoding/encoding of .srt files.  So how would I take a file without a subtitle stream and add a new one?  Something like:

ffmpeg -i mov.avi -i sub.srt output.avi

Sorry to ask again but I'm assuming since it's there in the documentation it works but I really can't figure it out.  Thanks!

Flarg... Could have sworn I tried this.

Works like a charm.

Not very experienced about subtitles and all, AFAIK subtitles support
in FFmpeg is still a bit... rudimentary.

But if you want subtitles in output you need a format which supports
them, I know matroska (.mkv) should do.

As for hardcoding subtitles right onto the video, I'm afraid we still
miss that facility (subtitles filtering + video overlaying seems the
right solution), correct if I'm wrong.

Message-ID: <CAHb4MBgTc4w0pgU240kLdtHc=6ngzb_XghsezpyeJ3D9NjfABg@mail.gmail.com>

Hello,

i have a problem with ffmpeg and time-lapse movies. I want to create a
time-lapse movie out of 80k jpg-pictures with a duration of ~5
minutes.

250 pictures/sec would be enough for 5,3 minutes.

But how?

I tried something like that:
 ffmpeg -r 250 -i %06d.jpg -vcodec libx264 -crf 22 -threads 0 -vf
scale=1920:-1 -r 15 -metadata title="foo" output.mp4

This works fine, but the video stops exactly after 46 seconds.

Here the log:
# ffmpeg -r 250 -i %06d.jpg -vcodec libx264 -crf 22 -threads 0 -vf
scale=1920:-1 -r 15 -metadata title="foo" output.mp4

Subject: [FFmpeg-user] Avid DNxHD QTs dropped/doubled frame problem
Message-ID: <20110824194441.GW7923@neoprimitive.net>

Hi, all.  I've run in to an issue when importing DNxHD Quicktime 
movies made with ffmpeg in to Avid Media Composer.
The source material are image sequences rendered at 24 FPS.

The output format is DNxHD 36 Mb/s, 23.976 FPS.

I am doing my encoding with ffmpeg SVN-r20372 packaged with Fedora 
Core 12.

All output movies from ffmpeg play back with the correct number of 
frames in mplayer on Linux, and in Quicktime on a Mac.

However, when the movies are imported in to an Avid Media Composer 
project set to DNxHD36, 23.976 FPS, movies with frame lengths ending 
in 0, 3, and 6 (e.g.  10, 13, 16, 20, 23, ...), have a doubled first 
frame, and a missing last frame.

All DNxHD36 Quicktimes created with Quicktime on a Mac maintain the 
correct order and number of frames when imported in to the Avid, which 
is why I think my problem originates with ffmpeg.


This is an example of my ffmpeg command on Linux:

ffmpeg -f image2 -r 24 -i ./1-20/test.%04d.tif -vcodec dnxhd -b 36Mb -r 23.976 -s 1920x1080 ./test.1-20.mov


This is the complete terminal output of the run.

Does anyone see anything conspicuously wrong with my command line that

I am trying to build ffmpeg 6.3.0 with VP8 support on OSX 10.6.6 with
Xcode 3.2.5 for the i386 architecture.

The ffmpeg configure phase fails with the error "ERROR: libvpx not
found", but the real issue is that libvpx.a is built for i386 only.
The ffmpeg build does not appear to support the i386 architecture,
instead building only x86_64.

Is this the case, or am I doing something wrong?  If it is the case,
is there a workaround?

Did you try 'ignoreQTrate True' in the Console in Avid? And/or AMA in 
instead of import?
Might solve something..
(but i use WriteAvidMXF and mediatool the material in, way faster)

If you really need i386 this isn't going to help...

Is there any reason why you cannot rebuild libvpx from sources?  I think
libvpx will default to the x86_64 target you need if configure is run
without arguments.  If not, you probably just need:

/path/to/libvpx/configure --target=x86_64-darwin10-gcc

Then the usual make/sudo make install will work (or tell ffmpeg where to
look at configure time, if you don't want to install).

Hi.
When running the command line below, I get "Option video_size not found."
I've tried -video_size hd720, with no effect.

How do you set the video size when using dshow? Thanks for any help you can
provide.

You can't yet it's not implemented, I believe (just looking at it, I
think maybe it's using DirectConnect to connect the pins, which just
always choose some default).

My current work around is to (are you ready for this?) create a
graphviz file with one box as your LifeCam, then add a "Tee" box and
connect the two.  Then right click on your output pin coming from the
LifeCam, and set the resolution. Save the graphviz file.
Now create an avisynth file like:

DirectShowSource("tee.grf", fps=2.0, audio=False, framecount=1000000)
(from https://github.com/rdp/dirt-simple-usb-surveillance/blob/master/tee.avs
)
Then use ffmpeg on that file as input. (you have to install avisynth
as well, obviously).
Phew!

I'd be willing to offer a bounty for somebody to implement it so that
you can select the size and the fps though, that would be sweet and
avoid this work around.

Thanks for the reply.  So what would be a working command line if the output was to .mkv for example?

$ ffmpeg -i INPUT -i SUBTITLE_FILE -y OUTPUT

then you should see something like this:
  Stream #0.0 -> #0.0: mpeg4 -> libx264
  Stream #0.1 -> #0.1: mp3 -> libvorbis
  Stream #1.0 -> #0.2: srt -> ass

You can set the subtitle output format to srt by using -scodec srt, or
forcing the copy with -scodec copy.

Hi Stephen,

The only information I have is regarding colorspace conversion such as from
YUV444 to YUV420p, this would reduce bits per pixel by reducing chroma
subsampling. This is possible through -vf format=yuv420p
I believe yuv420p is 1.5 bytes per pixel

If you're talking about going from truecolor color to other palettes such as
256-color, I don't see anything about that initially in libavfilter, but
would suggest looking for something like that in frei0r filters?

Either way these options will only work with a codec that supports different
colorspaces and color palettes, which, I'm not sure exactly which ones do.

Hope this helps,
~James

As far as I know, ffmpeg stopped using GIT, can you try SVN to head and
compile ? seems like an outdated or unknowably buggy one you have.

As far as I know, ffmpeg stopped using GIT, can you try SVN to head and compile ? seems like an outdated or unknowably buggy one you have.

This is what said on ffmpeg download page:
FFmpeg development has moved to a Git repository, and the SVN repository is no longer updated. The last revision committed to SVN was r26402 on 2011-01-19. The SVN repository may be removed in a near future, so you're recommended to use the Git repository instead.

This is a problem with your Solaris actually, you can do :

1. try searching for the libintl like *root at mytest: find / -name
libintl.so.3 ?ls *and if you find any instance, link it with *ln -s* to *
/usr/lib* and try again, Else
2. you have to install *libintl-3.4.0-sol8-sparc-local*  for the missing
libintl.so.3

Sorry I wrote it in the opposite way. Was pushing forward an update from
your side, but it seems you have the latest, I would say for my last help to
try to test the command using the normal stable ffmpeg tgz you download, to
see if that fixes the issue. Otherwise, I'm sorry, out of answers for your
issue.

Subject: [FFmpeg-user] read rtmp live stream delay
Message-ID: <CA+8UpDRH0zmLUqcaF9Jw54LW7QbcheeDD95EDU_ULRP5i8tp_A@mail.gmail.com>

Hey Guys,

I'm trying to load a live stream from red5 and save it to a file.
Using the following is resulting a very long delay (5 - 10 minutes) before
it start to read the stream:

 ffmpeg -i "rtmp://192.168.1.88/test/newTest test.flv
(I can see in the red5 logs that it connects and the stream starts)

if I use the live option, it connects and but the stream never plays:
ffmpeg -i "rtmp://192.168.1.88/test/newTest live=1" test.flv

Loading a static stream from red5 works just dandy.

Any suggestions would be appreciated.

Thanks!

Subject: [FFmpeg-user] Static compile with embeded 3rd party libraries.
Message-ID: <4E567829.1050508@bbc.co.uk>

Having been building ffmpeg statically for a while to avoid conflicts 
with distro versions by using:-

"... --enable-static --disable-shared ..."

I want to go one step further and end up with a portable executable that 
also includes all the third party libs such as lame faac etc. Googling 
around suggests adding in:-

"--extra-libs=-static --extra-cflags=--static"

However when I do this configure fails with an error saying it cannot 
find the third party libs.

"gcc -o /tmp/ffconf.kNbWfR0S /tmp/ffconf.htm52E9X.o -lfaac -lm -pthread 
-static
/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/bin/ld: 
cannot find -lfaac
collect2: ld returned 1 exit status
ERROR: libfaac not found"

I am obviously missing a bit, as it links to them fine without the extra 
two options. Can anyone assist in pointing me in the right direction?

Do you have a static libfaac?

Hi,
I've been trying to compile ffmpeg 0.8.2 on linux (rel6), and after compiling all the third party libraries I needed, I am getting the following error:


....

(and I've installed version 0.9.7 of libvpx)

Any ideas on what is happening or how to fix it? Thanks in advance,

Are you really using r15797? That's from 2008-11-09 and is considered
absolutely ancient. Why not at least attempt to use a recent FFmpeg
release (or Git master)?

What was your ./configure for libvpx?

If you compile ffmpeg with --enable-shared, then you probably should
also compile libvpx with --enable-shared. However, unless you know that
you absolutely need shared, then I recommend omitting --enable-shared
for ffmpeg and any required external libraries. Shared can be
problematic as you've experienced.

Navigate back to your ffmpeg source directory, run "make
distclean" (you might need to use sudo with that because you used sudo
with your ./configure for some reason) and try your ./configure again
without --enable-shared and optionally the others I listed below:

--enable-memalign-hack - I think this is a Windows specific option.
--enable-pthreads - should now be autodetected.
--enable-avfilter - looks like it's a default option.

Subject: [FFmpeg-user] Problem with -f video4linux2 thru all versions from
 stock Ubuntu 0.5.1
Message-ID: <4E56A929.8050901@earthplanet.org>

Hello,

I'm having problems with v4l2 indev on ffmpegs > 0.5.1.

Ubuntu 10.04 LTS (fresh install), stock kernel 2.6.32-33-generic.

cmd line: ffmpeg -f video4linux2 -i /dev/video0 1.avi

v4l device as per dmesg:

[39444.503733] DVB: registering adapter 0 frontend 0 (A827[0] DVB-T)...

Everything works fine with ffmpeg found in this Ubuntu version's 
aptitude, which I believe is 0.5.1 (at least it works at all, im using 
it for streaming mpeg4 via ffserwer and it get clogged after a couple of 
hours, that's why im trying newer versions).

I've tried releases 0.6.3, 0.7.3 and 0.8.2, also tried latest (a couple 
of minutes ago) git clone from git://git.videolan.org/ffmpeg.git. All of 
them give more or less the same output:

Is there anything I can do about it? I'd rather not go back to 0.5.1 as 
there cleary were some issues with mpeg4 or ffserver which I hope are 
fixed now.

Best regards,

Thanks. I'll try that out. I believe I probably did not use the --enable-shared option for libvpx.

Can you give us full output from the flv input?

I suspect it may be a colorspace issue, in which case you can use -vf
format='pixel_format' to correct it.

Also, I use -vcodec mjpeg to get jpeg still frames rather than -f image2.
Perhaps that may work?

Hope this helps,

Thanks a lot, Mike.

I applied that patch to ffmpeg from git as of an hour ago, compiled, 
and it did indeed produce a DNxHD36 Quicktime that imported in to our 
Avid without the problems I was seeing before.

So, is this an ffmpeg bug, or an Avid bug?

If the former, was this patch submitted to the ffmpeg-devel list?  Any 
idea why it hasn't yet been merged in, or an equivalent fix made since  
the problem has been identified?

Here is the patch again against current ffmpeg source.

Thanks, Bouke.  Setting 'ignoreQTRate' to 'true' does seem to solve 
the problem on import for the time being.  This gives me time to look 
in to the feasibility of deploying a new ffmpeg binary built with Mike 
Root's patch.

Are there wider implications for our project if we just leave this 
option set to true in the Avid?  This may be veering in to OT land 
(e.g. Avid support), so I guess, if you have any advice, reply 
off-list.

Cheers,

J

I've found that I don't need --extra-libs=-static or
--extra-cflags=--static if compiling third-party libs with
--disable-shared. Since a .dylib (Mac OS X) is not generated, gcc by
default compiles statically with the .a version of the library.

I have to give the path to the library for this to work, which
sometimes is put in a hidden directory. Here's an example:

$ cd /libfaac
$ ./configure --enable-static --enable-shared=no --without-mp4v2
--build=x86_64-apple-darwin10
$ make

This compiles and puts libfaac.a in /libfaac/.libs/libfaac.a (yes,
that's a dot in front of libs)

Since I don't do "make install," I must specify the absolute path to
the lib in ffmpeg's configure line:

$ cd /ffmpeg
$ ./configure $CONFIG_STUFF --extra-cflags=-I/libfaac/include
--extra-ldflags=-L/libfaac/.libs
$ make

That should generate a static binary that includes libfaac.

As far as I'm concerned, it's a Quicktime bug--meaning, the entire format itself 
is an unholy mess of things that are undocumented, half implemented, or wrongly 
implemented.  For what it's worth, I don't think it's an Avid problem--If I 
remember correctly, qtpro was doing the same thing.

It hasn't been submitted to ffmpeg-devel.  I only just got on the ffmpeg-user 
list the other day.  Don't usually have the bandwidth...  I'll add myself 
though.  Got some "fun" questions about DNxHD colorspace. :)

According to yast, yes!

libfaac-devel - Header files and static library for the faac library

You might want to check that.  I thought static libs were usually *.a

Try setting a small probesize (-probesize 32768).  I find this helps on 
network streams that don't provide duration info, such as live streams.

"so" means "shared object" as far as I know. That's a shared lib.
Static is .a, as James pointed out.

FYI, on Mac OS X shared libs have a .dylib extension.

Ahh. I'm more of a dynamic language man myself, C(++) not really my 
thing, so I'm still get used to the intricacies of compiler/linking etc.

So I will need to build all the third party includes statically first 
then, as the distro only includes the shared.so and C headers....

Useful info...

Thanks for all this.

Ok so I was able to get this to work thank you for that!  It was successful going to .mkv but not to .avi or .mp4 (container doesn't support .srt it says).  I guess that's what you meant when you said it was limited?  Well hopefully we will see more from this in the future because it would be great! :-)  This is also nicer than hard-coding the subs...

Yeah, you'll need to compile your third-party libs from source using
--disable-shared on the configure line.

You can probably do "make install," which will put the static libs in
system location(s). FFmpeg's configure should then be able to find
them. I don't like doing this though because I would rather not junk
up my system with static libs that I only use to build static binaries
of other programs. This is a problem though, because once you compile
many third-party libs they put the libs in some hidden directory. So,
you might have /libfaac/include with your headers, but no libfaac.a is
obvious so you don't know what path to give to configure. That's
because it's in /libfaac/.libs/libfaac.a, which is hidden. I
discovered that several third-party sources do it this way. I'm not
sure why, but it's annoying.

If anyone has a better solution to this, I'd love to hear.

Subject: [FFmpeg-user] syncing x11grab with a drawing application
Message-ID: <4E57A3CC.5030200@gmail.com>

Dear ffmpeg-users,

I would like to use ffmpeg's x11grab input with a (legacy) X application
in such a way that the captured frames are synchronized to the
application's output.

To be more precise, I would like to somehow notify ffmpeg every time
when the application has finished drawing a frame, so that ffmpeg can
capture it.
When it has captured it, then the application would move on to draw the
next frame.

No audio is involved, so the only concern of synchronization is the
application drawing the frames.

Is something like this supported?

(Obviously, I would need to add the special notification code to the
application, but that's ok.)

Thank you for your help:


     Kristof Csillag

The problem is persists only when muxing to flv container,
I tried muxing into 3gp, avi, mp4 - no problems.

ffmpeg -i /home/vmedia/public_html/viewstream/41167.mp4 -acodec copy -vcodec copy -sameq -f flv a.flv - fails...

can I submit a bug for this issue?
thank you.

This is what said on ffmpeg download page:
FFmpeg development has moved to a Git repository, and the SVN repository is no longer updated. The last revision committed to SVN was r26402 on 2011-01-19. The SVN repository may be removed in a near future, so you're recommended to use the Git repository instead.

As far as I know, ffmpeg stopped using GIT, can you try SVN to head and compile ? seems like an outdated or unknowably buggy one you have.

Message-ID: <CAAu=x1_xPxC9umOyDxd8jQXaiVebsg6v_UerrD1AGih39Fbzrg@mail.gmail.com>

Hello all,

Is there any way to skip a specific number of frames in the start of a mp4
stream? I know the number of frames I want to skip and am guaranteed that it
will be a reference picture. But I do not know it in seconds. I guess if a
stream has different frame rates it would mean I would have to manually
convert from frames to time offset. Or is there a way on the command line?

Cheers!

Hi,

I'm trying to compile ffmpeg with the libx264 library (both cloned from

get the following error:

/sources/ffmpeg/libavcodec/libx264.c:452: undefined reference to

My Google-fu has failed me on this one. Can anyone help?

You can try with the select filter, for example to skip the first 10 frames:
-vf select="gte(n\, 10)"

It looks like the version you are using for compilation (.h files) is not
the same as the version you are using for linking (.a or .so files). Look at
the -I and -L options to the compiler.

Hi All,

I am using FFMPEG for transcoding of  MP4 files.
Could any one pls tell me what all video\audio codec combination are
supported by ffmpeg in MP4 container.
MP4 by definition does not specify the supported audio\video codec list.

Any pointer orhelp on this will help me in moving forward.

Thx in advance.

Subject: [FFmpeg-user] Audio compression optimization
Message-ID: <5D33B6A3E32746F58B26CD4C62D4F6C3@laptop>

Hi,


We would like to share an article on audio encoding optimization for podcasting. No need to think what bit rate to choose the batch file will automatically encode your source audio with the best bit rate to preserve the best quality and smallest file size. The approach was tested on MP3, Nero AAC and OGG.


This paper will give you understanding on how one can achieve better compression ratio by bit rate optimization. The key point is that our approach describes a fully automated manner of choosing the bit rate that will preserve the audio quality you define. Read this paper through and find out how to save on size when encoding your podcasts, save on bandwidth when transmitting your audio streams in the network, make more audio tracks fit your memory stick when grabbed from a CD, or store more audio books on your mobile device. This paper will tell you how to save up to 50% on audio file size and up to 50% on the bit rate you encode your audio with still having a descent sound quality.

Read full text of how to encode audio with lowest bit rate at highest quality in this blog post: http://blog.sevana.fi/optimize-bitrate-and-size-preserving-high-audio-quality-in-tracks-podcasts-tunes-with-aqua-wideband/

I think you're right. I have two versions installed, one in /usr and one
in /usr/local. For some reason the configure script is finding the
version in /usr/local, but at compile time it's trying to use the one in
/usr. I don't really know how configure and make work, so how can I work
out why it's confused?

Steve.

The configure for ffmpeg has the unusual behaviour that it does not try to
look in /usr/local like most autoconf-produced configure. You can tell it to
with the following options:

  --extra-cflags="-I/usr/local/include"
  --extra-ldflags="-L/usr/local/lib"

But before that, you should look at the compile and link lines, with
make V=1, and look in config.log to see where the strange flags come from.

OK, so in config.log I'm seeing the following:

check_lib x264.h x264_encoder_encode -lx264
check_header x264.h
    1	#include <x264.h>
/usr/local/include/x264.h:36:4: warning: #warning You must include
stdint.h or inttypes.h before x264.h

so the #include directive is picking up x264.h in /usr/local. This seems
to go against what you say about it only looking in /usr/lib, although
it could be that my build setup is overriding ffmpeg's wishes at this stage.

The compile line that fails is:

gcc -Llibavcodec -Llibavdevice -Llibavfilter -Llibavformat -Llibavutil
-Llibpostproc -Llibswscale -Wl,--as-needed -Wl,--warn-common
-Wl,-rpath-link=libpostproc:libswscale:libavfilter:libavdevice:libavformat:libavcodec:libavutil
-o ffmpeg_g ffmpeg.o cmdutils.o -lavdevice -lavfilter -lavformat
-lavcodec -lpostproc -lswscale -lavutil -ldl -lX11 -lXext -lXfixes
-lxvidcore -lx264 -lvorbisenc -lvorbis -logg -ltheoraenc -ltheoradec
-logg -lopencore-amrwb -lopencore-amrnb -lmp3lame
-L/usr/lib/x86_64-linux-gnu -lfreetype -lfaac -lm -pthread -lz

so there's no specific directive to look anywhere for libx264 (it's just
-lx264). This must be why it's falling back to /usr/lib without the
extra compile flags.

Using the explicit flags you mentioned above works perfectly.

Thanks for the help.

Steve.

PS If you want me to do more tests, just let me know.

That's the normal behaviour. The strange part is that it finds x264.h in
/usr/local.

You may want to try to compile the following program:

#include <stdint.h>
#include <x264.h>
int main(void) {
    x264_encoder_open(0);
    return 0;
}

with just -lx264. If it compiles but fails to link, then there is something
seriously inconsistent in your compiler's settings, and it will probably
cause you trouble again later. If it fails to compile or success entirely,
it is probably a problem in ffmpeg's configure.

> Using the explicit flags you mentioned above works perfectly.

Glad I could help.

Subject: [FFmpeg-user] Overlay, video ontop instead of below.
Message-ID: <4E5A9A6C.5050404@engene.se>

Hi,

If I run this...
ffmpeg -i apa.mov -y -vf 'movie=checkerboard640x480.png,crop=640:360 
[ch];[ch][in] overlay=0:0:1 [out]' -acodec copy -vcodec png citron.mov
...it hangs (full cpu and file does not grow). Note [ch][in] instead of 
(working) [in][ch].

Is it possible to do what I want to accomplish somehow? I have vids with 
transparency I want to put on top of an image.

Thanks,
Marcus

Just to add on some more details:

Does FFMPEG supports H264 with NellyMoser in MP4 files.??
I have a mp4 file, which contains h264 video and Nellymoser Audio.
And FFMPEG is throwing error when this file is used as an input.
Its working fine when MP3 is used with H264 in MP4 file.

Thanks in Advance.

Raman Gupta

Hi Carl,
Thanks for your response.
I have uploaded the MP4 file at:
http://www.datafilehost.com/download-10082e81.html

The file can be streamed through Flash Media server and can be played
in Flash Player.
On using ffmpeg its throwing error that no decoder found for audio codec id.
NellyMoser in flv format works fine with ffmpeg, but it throws error
if NellyMoser in MP4  is used with ffmpeg

Any help would be appreciated.
Thanks,
Raman Gupta

This sounds like an incorrect audio codec has been used within the mp4
container; which codec did you use for the audio?

The CoDecs that I know of for mp4 are AAC, AMR and ALAC. There may be more.
I personally use AAC-LC.
You can Google search for more info and check out these 2 sites as well

	configurable"
Message-ID: <CAL1QdWeAeLni_1BW+e+W2AbV2=5Vr5T7jnJS+b32KBZGZuN-=Q@mail.gmail.com>

Hello all.
I've decided to offer a small bounty ($250) for any enterprising
developer interested in the following task:

Background:

ffmpeg can take dshow input, like
$ ffmpeg -f dshow -i video="USB2.0_Camera":audio="Microphone (USB
Audio Device)" output.mkv

However you can't specify "1280x1024 7.5fps"  (instead it chooses some
poor default like 640x480 10 fps).

So this would be a task to make this possible. Example open source
programs that do this apparently already: VLC, iSpy.

Extra credit if you can enumerate available dshow capture devices
(video+audio): $50
Extra credit if you can enumerate the options of a given capture source. $50
Extra credit if you can set options for audio: $50

Related thread:

>> When running the command line below, I get "Option video_size not found."

Subject: [FFmpeg-user] YUV 422P Conversion Clipping detection
Message-ID: <1314650507833-3777344.post@n4.nabble.com>

I'm trying to detect clipping when converting from YUV422p to RGB24. I've
looked through some of the variables included when calling sws_scale() but
didn't find any flags that stood out so I'm trying to convert manually using
the descriptions on wikipedia. http://en.wikipedia.org/wiki/YCbCr

I've tried several different methods of converting but I don't seem to be
getting the proper rgb values. sws_scale converts the image properly however
when I convert it I get values between 16-20; 

'img' is just a small struct wrapping the frame
'frame' is the AVFrame containing the image

int vc = 0, uc = 0;
for(DWORD i = 0; i < img.width - 1; i += 2) {
		float y1 = img.frame->data[0][i];
		float y2 = img.frame->data[0][i+1];
		float u = img.frame->data[1][vc++];
		float v = img.frame->data[2][uc++];
		
		//int Cr = u;
		//int Cb = v;

		//float r = y1 + 1.402f * (Cr - 128);
		//float g = y1 - 0.344f * (Cb - 128) - 0.714 * (Cr - 128);
		//float b = y1 + 1.772f * (Cb - 128);
		//int r = y1 + Cr + (Cr >> 2) + (Cr >> 3) + (Cr >> 5);
		//int g = y1 - ((Cb >> 2) + (Cb >> 4) + (Cb >> 5)) - ((Cr >> 1) + (Cr >>
3) + (Cr >> 4) + (Cr >> 5));
		//int b = y1 + Cb + (Cb >> 1) + (Cb >> 2) + (Cb >> 6);
		float r = 255.f / 219.f * (y1 - 0.f) + 255.f / 112.f * 0.701f * (u -
128.f);
		float g = 255.f / 219.f * (y1 - 0.f) - 255.f / 112.f * 0.886f * 0.114f /
0.587f * (v - 128.f) - 255.f / 112.f * 0.701f * 0.299f / 0.587f * (u -
128.f);
		float b = 255.f / 219.f * (y1 - 0.f) + 255.f / 112.f * 0.886f * (v -
128.f);
		
		rMax = (r > rMax) ? r : rMax;
		gMax = (g > gMax) ? g : gMax;
		bMax = (b > bMax) ? b : bMax;

		rMin = (r < rMin) ? r : rMin;
		gMin = (g < gMin) ? g : gMin;
		bMin = (b < bMin) ? b : bMin;
		
// ..... repeat for y2

}

Thanks for your time.

Message-ID: <CAPAO68W_Q79QAiwEf2qSG17ZDJCOWaC_6Y372dzsW7SRpyNC3w@mail.gmail.com>

Hello List,

Does anyone know why this error is occurring when running ffprobe or ffmpeg
on a DNxHD 36 MXF file?

[mxf @ 02a108c0] error, essence data could not be found

Here are a couple of example files
http://kcintrab.com/examples/21228257V01.4E5282E6.9364A0.mxf - 259 MB
http://kcintrab.com/examples/reel_1ab_grd27.88919.mxf - 719 MB

Does something need to be added to be able to support these files?  I'd be
willing to do some coding, but need some direction as to what needs to be
done.

thanks much,
Greg

Before I waste bandwidth downloading these, I notice that one of them 
has "...V01..." embedded in the filename suggesting it is a video only 
file (Avid media??). Could it therefore be that the file is an op atom 
mxf which ffmpeg does not support?

Yes that does look to be the case.  The files are OP-Atom format.

Subject: [FFmpeg-user] Unable to remove ffmpeg
Message-ID: <001e01cc64af$13df08a0$3b9d19e0$@com>

Hi,

 

 We have installed ffmpeg on centos using make and make install, that was
installed perfect.

 

Now we want add speex codec in that, so we have tried uninstall the ffmpeg.

 

We have used the following command

 

Yum remove ffmpeg x264 faad2 faad2-devel  also we have tried make uninstall

The ffmpeg was not removed, so we have deleted the ffmpeg directory from the
server.
Again we have download and try to install at this time we are getting the
following error.
Makefile:1: config.mak: No such file or directory

make: *** No rule to make target `/tests/fate/vp8.mak'.  Stop.
 
So please help us  how can we remove the ffmpeg completely and install
again.
Is there any way to include the speex codec without re-install?
Please help us on this.
 
Thanks
Nanda

According to the docs, "-f nnn" is used to force the format when it 
cannot otherwise be determined by the file extension. Since I have 
specified a file extension compatible with the required format I would 
not expect the -f to be necessary.

As it happens the above does not work and fails in the same way.

However I have found the cause of the issue and its an old gotcha I 
spotted when looking at my working version-

Stream mapping:
   Stream #0.0 -> #0.0: dvvideo -> dvvideo
   Stream #0.1 -> #0.1: pcm_s16be -> pcm_s16le

The DV mov has the audio be, but ffmpeg insists that for .dv streams the 
audio must be le, so the solution to my issue is:-

ffmpeg -i SYNCTEST.mov  -vcodec copy out.dv

which gives:-

Stream mapping:
   Stream #0.0 -> #0.0: copy
   Stream #0.1 -> #0.1: pcm_s16be -> pcm_s16le

Thanks for all your thoughts though...as trying your solutions and 
failing put me on the right track!

The reason why i try to do this, i need to pad the 4:3?aspect ratio 1080p input so that it is fullHD (1920x1080) , then apply a fullHD png logo watermark in top left corner.

Can you guys see what i'm doing wrong? I even tried to put the pad filter after watermark to see if i get any changes, although that's not the right order in which i want this done, then message is Not enough inputs specified for the "pad" filter., with a command like

ffmpeg -y -i 00728.mts -f mp4 -vcodec libx264 -r 25 -b 5000000 -s 1440x1080? -vf "movie=logo.png[watermark];[in][watermark]overlay=10:10[out],pad=1920:1080:240:0" -g 250 -threads 0 -pix_fmt yuvj420p -deinterlace -coder 1 -flags +loop -cmp +chroma -partitions +parti8x8+parti4x4+partp8x8+partb8x8 -me_method hex -subq 2 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 1 -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -bf 3 -refs 1 -directpred 1 -trellis 0 -flags2 +bpyramid-mixed_refs+wpred+dct8x8+fastpskip -wpredp 0 -rc_lookahead 10 -acodec libfaac -ar 44100 -ab 320000 -ac 2 img.mp4

Try this

Any filter needs an input and if you don't specify one, it will take the last used/available.
You cannot reuse an already used input. To work around this, the op split= was introduced, but in my opinion fails to work. I always get grey instead of content on the second output of split.

It definitely works so thank you very much for the solution. Unfortunately i don't really understand what you did.


If you have the time, could you explain what the [p] is going on there?

Thanks in advance.

Sure, Andy!

I first explain, why/how my solution works:
The -vf parameter can be split into 3 independant parts, separated by semicolons
1 [in]pad=1920:1080:240:0[p]
   Takes the first and only input video with the portlabel [in], pads it 
   and stores the result in port [p]. You could ommit [in] because the only availabel port to 
   feed pad in this part of vf would be [in] and pad would take it.
2 movie=logo.png[watermark]
   Does not consume or need any input port, but feeds an output that is manually 
   labeled [watermark] for later reference
3 [p][watermark]overlay=10:10[out]
   The overlay needs two inputs that we gave in the proper order.
   If the last output of the prior node is identical to the first input needed for the current,
   I could skip naming them and replace ; by a , so both nodes are chained together

I don't know if separating node chains with ; and labeling all in/ouputs causes performance penelties, but it helped me a lot to understand what happens when.
