[00:41] <jack_> i need a command that converts any format to lossless audio and video for the xbox 360
[00:44] <jack_> anyone?
[00:50] <mishehu> welp too bad he didn't hang around, nobody can help him if he's not here heh.
[01:18] <hyperkineitc> Unless this is logged by a bot.
[01:29] <mishehu> burek: it's still not showing the subtitle stream even with an immediate ffmpeg checkout.
[01:29] <mishehu> doesn't make sense because when I watch the video in xine or on a bluray/dvd player I can select the subtitles and get it
[01:30] <mishehu> then again, I'm not getting any listing for any subtitles on any of my files with just ffmpeg -i
[01:33] <Belial> I am trying to convert 3gp videos to mp4 (or avi or anything else) but whenever I do a search online, EVERY ffmpeg command string offered fails. Example: ffmpeg -i input.3gp -f mp4 -vcodec libxvid -acodec mp3 -ar 22050 output.mp4  produces "unknown codec 'libxvid'".  Same error no matter what codec I try.  I have EVERY codec on my system.  Has the syntax been changing a lot or something?
[01:35] <mishehu> Belial: do you want to use xvid4 as the underlying video codec?
[01:35] <mishehu> you could also try x264
[01:36] <Belial> mishehu: i don't need to but it seems whenever I use any codec...i want something that will produce a video that windows users can view out of the box if possible.
[01:36] <mishehu> xvid4 ain't gonna be that codec then
[01:37] <Belial> mishehu: I get the same error if I use -vcodec x264.  Unknown encoder?!  WTF?
[01:38] <mishehu> Belial: ffmpeg -codecs
[01:38] <mishehu> that will list off your available codecs
[01:38] <mishehu> also `man ffmpeg` can be of use though yes, it can be confusing to the beginner
[01:44] <Belial> thx
[01:55] <mishehu> lovely, now it doesn't like -acodec copy or -vcodec copy
[01:55] <mishehu> Unknown decoder 'copy'
[02:13] <dr_phresh79> anyone here?
[02:21] <dr-phresh7> xbox 360 output command?
[06:26] <hyperkineitc2> I am trying to transcode a low bitrate (564 kb/s) h264 stream in a .mpg container to dvvideo. The problem is the output bitrate is 28771 kb/s!!
[06:26] <hyperkineitc2> Command was: ffmpeg -i DVR-01.h264 -y -threads 2 -map 0.0:0.0 -f dv -vcodec dvvideo -vb 1024 -target ntsc-dv -aspect 4:3 -qmin 2 -qmax 15  -benchmark /Volumes/LaCie/DVR-01.dv
[06:27] <relaxed> dv is huge
[06:29] <hyperkineitc2> I get that, but there was only so much information packed into the original .5Mb/s
[06:29] <relaxed> your attempts to confine the bitrate are futile
[06:29] <hyperkineitc2> I'll take your word for it.
[06:30] <relaxed> You should. What is your goal?
[06:31] <hyperkineitc2> Put it in a format suitable for editing on a Mac.
[06:31] <relaxed> It must support some lossless format. How can it not accpet h264?
[06:31] <relaxed> accept*
[06:31] <hyperkineitc2> I think it's confused by the .mpg container.
[06:32] <relaxed> stream copy to .mov
[06:32] <hyperkineitc2> Also, the original was written by some cheesy DVR. Most utilities I've thrown at it complain about it missing time code.
[06:32] <relaxed> By Mac I assume you mean FCP?
[06:33] <hyperkineitc2> I could install that. Was aiming low and using iMovie. Just need to do a few basic cuts between two tracks, maybe add audio at some later date.
[06:35] <hyperkineitc2> So just change the vcodec and file extension? Any other flags to add/omit?
[06:35] <relaxed> I would think h264/aac in mp4 could be decoded my imovie.
[06:36] <relaxed> Well, nothing surprises me when it comes to apple products.
[06:36] <hyperkineitc2> I've extracted the h264 stream raw. Don't have an audio track. Is it required?
[06:37] <relaxed> I have no idea. My last apple product was an apple IIe.
[06:37] <hyperkineitc2> Even VLC acts a little funky playing it.
[06:37] <hyperkineitc2> I suspect the source *barely* conforms to h264
[06:39] <relaxed> luckily ffmpeg can transcode pretty much anthing into rainbows and unicorns. You just have to know which you need.
[06:40] Action: relaxed prefers unicorns
[06:44] <hyperkineitc2> ffmpeg -i DVR-01.h264 -y -threads 2 -map 0.0:0.0 -f mov -vcodec copy -vb 1024 -aspect 4:3 -qmin 2 -qmax 15  -benchmark /Volumes/LaCie/DVR-01.mov
[06:44] <hyperkineitc2> Seems to be on it's way. Missing anything?
[06:45] <hyperkineitc2> I'm not terribly conversant in arcane codec internals.
[06:47] <relaxed> If you're copying the stream you can't change anything.
[06:48] <relaxed> ffmpeg -i DVR-01.h264 -c:v copy output.mov
[06:50] <relaxed> I would think googling "ffmpeg imovie" would present some solutions.
[07:02] <hyperkineitc> frame=1483242 fps=7532 q=-1.0 Lsize= 3666774kB time=00:00:00.00 bitrate=2730746965090.9kbits/s
[07:02] <hyperkineitc> video:3666774kB audio:0kB global headers:0kB muxing overhead 0.000000%
[07:03] <hyperkineitc> Check out that bit rate!!!!
[07:04] <relaxed> ignore it
[07:27] <hyperkineitc> So, what's a good resource for wrapping my head around what does what? Some flags seem straight forward, but many appear to require understanding codec innards.
[16:07] <EricAhn> how can I get average bitrate of mp3 files?
[16:07] <EricAhn> mp3=>mp4
[16:07] <EricAhn> how can I get average bitrate of mp4 files?
[16:07] <burek> divide the size of a file with its length (duration)
[16:08] <EricAhn> mvhd.duration = 10256741 and file size = 888,462,643
[16:09] <EricAhn> in this case, average bitrate is?
[16:09] <burek> use the calc
[16:09] <iive> size*8/duration
[16:09] <iive> *8 is for getting it in bits.
[16:09] <burek> yes
[16:10] <EricAhn> 692bits ^^ thanks
[16:12] <burek> EricAhn, your duration is very suspicious
[16:12] <burek> is it in seconds
[16:12] <burek> or milliseconds
[16:13] <EricAhn> I'm goint to apply throattling in http server.
[16:13] <EricAhn> Just need seconds .
[16:14] <EricAhn> in http://www.code-shop.com/, mod_h264_streaming plugin give some wrong bitrate.
[16:14] <iive> i'd say that the bitrate is insanely low.
[16:14] <sacarasc> Probably meant kb.
[16:15] <EricAhn> usually kb
[16:15] <burek> or milliseconds
[16:15] <iive> not likely, if the duration is in seconds it would be 118 days of video.
[16:18] <EricAhn> hm, when I saw mediainfo, it display "Overall bit rate" : 693Kbps,
[16:18] <burek> yes, that's ok
[16:18] <EricAhn> different 692bit and "Overall bit rate":693Kbps
[16:18] <burek> EricAhn, your duration is in milliseconds (for the 3rd time)
[16:19] <EricAhn> burek, ahn
[16:19] <EricAhn> brek, ah
[16:19] <burek> :D
[16:34] <EricAhn> code-shop.com just counting for bitrate, http://pastebin.com/afx4xtAB
[16:50] <sp_> hi
[16:50] <sp_> I'm running into "Unknown encoder 'libx264'"
[16:50] <sloop> how do I specify an alternate path to yasm when running ./configure ?
[16:50] <sp_> but I seem to have libx264 installed
[16:51] <burek> sp_, type ffmpeg -codecs | grep 264
[16:51] <burek> sloop, use --extra-ldflags and --extra-cflags
[16:51] <burek> or even better, type ./configure --help
[16:52] <sp_> burek: got a few lib lines but no libx264
[16:52] <burek> sp_, you need to compile your ffmpeg with libx264 support
[16:53] <sp_> so it's a problem with my compile statement?
[16:53] <burek> sure
[16:53] <sp_> I'm already --enable-libx264
[16:53] <burek> did you compile libx264?
[16:53] <burek> did you install libx264-dev
[16:53] <sp_> yes
[16:53] <burek> oh
[16:53] <sp_> not sure
[16:53] <burek> ok, just one is needed
[16:53] <sp_> about -dev
[16:53] <burek> not both
[16:53] <sp_> I'm on centos6
[16:53] <sloop> burek, thanks I figured it out.. took me awhile to realize it was looking for the yasm binary
[16:54] <burek> if you compiled libx264 then ffmpeg should show it
[16:54] <sp_> during the /configure I get ERROR: X11 not found
[16:54] <burek> when you do ./configure ..
[16:54] <sp_> just noticed
[16:54] <burek> in that big list
[16:54] <burek> scroll up
[16:54] <burek> to the section "Encoders:"
[16:54] <burek> and see if libx264 is ther
[16:54] <burek> if not, then ffmpeg didn't find your compiled x264
[16:57] <sp_> any idea on ERROR: x11 not found ?
[16:57] <sp_> I think that is the problem
[16:57] <sp_> it interrupts the configure
[16:57] <burek> sp_, take a look at config.log
[16:57] <burek> find the last error
[16:57] <burek> and you'll see what's wrong
[16:58] <sp_> xlib.h
[16:58] <burek> http://ffmpeg.gusari.org/irclogs/2012/05/17/ffmpeg.log.20120517
[16:58] <burek> search for 'x11 not found'
[16:59] <sp_> ok
[16:59] <sp_> thanks!
[16:59] <sp_> should I use the same package names for yum? how can I translated deb to yum package equivalents?
[16:59] <burek> oh :) I don't know :)
[16:59] <burek> google? :)
[17:00] <Bombo> i want to change the framerate of an audio stream from ntsc(23.975) to pal(25.000), i tried 'ffmpeg -i ntsc-23fps.ac3 -acodec libmp3lame -ab 128k -ac 2 pal-25fps.mp3' with -f 25 and -target pal-dvd but the target files are never pal/25fps... any hints?
[17:00] <sp_> it was libX11-devel
[17:00] <sp_> :P
[17:00] <sp_> yum search
[17:01] <burek> Bombo, audio stream? :D
[17:01] <sp_> sorry for the newbish question just wanted to know if there was better way
[17:01] <burek> since when an audio is in ntsc/pal format? :)
[17:01] <burek> sp_,  ok :)
[17:01] <Freakshow> :P
[17:03] <Bombo> burek: yes
[17:03] <burek> Bombo, what exactly are you trying to accomplish?
[17:03] <Bombo> burek: i got german pal video stream and want to mux english audio
[17:04] <Bombo> (from a ntsc source)
[17:04] <burek> use an audio editor to speed up/slow down an audio and then mux it? :)
[17:06] <Bombo> is there one that accepts fps rates as input?
[17:06] <burek> I don't know.. Use google?
[17:08] <Bombo> what if not, how do i calculate the right settings?
[17:09] <sp_> .configure ran fine
[17:09] <burek> btw, are durations of both videos the same?
[17:09] <sp_> but while making: final link failed: Bad value
[17:09] <burek> sp_,
[17:09] <burek> can you please use pastebin.com, to show your command line and its output?
[17:09] <sp_> okay
[17:10] <Bombo> burek: thats the problem, english is ~4minutes longer, because its lower framerate
[17:10] <sp_> http://pastebin.com/ZsPFkp5u
[17:10] <burek> well, specify in audio editor that you want an audio 4 minutes shorter
[17:11] <sp_> the last 4 lines are relevant
[17:11] <burek> relocation R_X86_64_PC32 against undefined symbol
[17:11] <burek> that is your error sp_
[17:12] <sp_> I tried searching for that in the log you linked me too
[17:12] <sp_> but didn't find anything
[17:12] <burek> this might help: http://www.google.com/search?q=relocation+R_X86_64_PC32+against+undefined+symbol+
[17:13] <JEEB> the glibc seems to be compiled static without PIC while you're building shared?
[17:13] <JEEB> "can not be used when making a shared object; recompile with -fPIC"
[17:13] <JEEB> is the hint
[17:13] <sp_> so I should recompile glibc
[17:14] <sp_> damn, I've no idea where to start
[17:14] <JEEB> or wait, did you re-configure something and not make clean it?
[17:14] <sp_> YES
[17:14] <JEEB> as in ffmpeg
[17:14] <sp_> yes yes yes
[17:14] <sp_> I'll make clean and try again
[17:14] <JEEB> try make cleaning it up once
[17:14] <JEEB> yeh
[17:14] <JEEB> could be some weird leftovers
[17:15] <sp_> fingers crossed
[17:15] <JEEB> otherwise just try building static? :D
[17:15] <JEEB> (since that shouldn't need PIC)
[17:16] <JEEB> Bombo, most NTSC->PAL conversions are done with plain speed-up, so you can take the difference of 24000/1001 and 25 and just slow down the audio by that amount
[17:17] <L1nux> hi
[17:19] <L1nux> i need to play stream mjpeg video from motion (webcam) software using ffplay
[17:19] <L1nux> is possible ?
[17:20] <Bombo> 25-24000/1001 == 1.024
[17:21] <Bombo> is there a 'slow down' filter in sox?
[17:21] <burek> L1nux, yes
[17:22] <burek> ffplay http://ip:port/
[17:22] <L1nux> burek, not work :S
[17:22] <L1nux> the header of strem:
[17:22] <L1nux> --BoundaryString^M
[17:22] <L1nux> Content-type: image/jpeg^M
[17:22] <L1nux> Content-Length:        4060^M
[17:22] <burek> what exactly is the url
[17:23] <L1nux> in my local network
[17:23] <burek> try ffmpeg -i url
[17:23] <L1nux> http://192.168.1.6:8081/strem.mjpeg
[17:23] <Bombo> speed factor[c] Adjust  the  audio speed (pitch and tempo together).  factor is either the ratio of the new speed to the old speed
[17:23] <Bombo> hmm
[17:23] <burek> and paste the results to pastebin.com
[17:25] <sp_> it compiled correctly
[17:25] <sp_> thanks burek that was really helpful
[17:26] <Bombo> step 1: ffmpeg -i english.ac3 english.wav
[17:26] <burek> :beer: :)
[17:29] <L1nux> burek, is work, but after much time
[17:29] <burek> good, did you test on the movie?
[17:30] <L1nux> burek, http://pastebin.com/75zfJHFe
[17:32] <L1nux> i need to play quickly :)
[17:32] <burek> well, you can't
[17:32] <L1nux> not after 5 minutes
[17:32] <burek> oh
[17:32] <burek> first of all
[17:32] <burek> your ffmpeg is really old
[17:32] <L1nux> is need 5 minutes to play ???
[17:32] <burek> it might help if you use the latest git version
[17:33] <L1nux> is pkg from debian multimedia (stable)
[17:33] <burek> don't use that
[17:33] <burek> compile it
[17:33] <Bombo> step 2: 'sox -S english.wav english-pal.wav speed 1.024'
[17:33] <Bombo> takes forever
[17:33] <burek> Bombo, ask on the sox support channel?
[17:33] <Bombo> burek: ask what?
[17:34] <burek> a question usually :)
[17:40] <Taladan> Quick question.  I use FFMPEG to do both desktop capture (for youtube videos) and for streaming out to a video site (twitch.tv).  I've noticed & had people tell me that the audio is 'crackly'.  There seems to be some choppiness in the audio no matter what codec I use.  Has anyone else encountered this and come up with a fix?
[17:43] <burek> Taladan, how exactly do you stream it, do you have a cmd line example?
[17:43] <Taladan> yeah
[17:43] <Taladan> give me a sec and I'll link
[17:43] <L1nux> burek, is work quickly if i save a file (stream.mjpeg) using wget and play it localy
[17:44] <Taladan> https://docs.google.com/file/d/0B7JCjpvY2cExVEFqX1Uxcjl3ZWM/edit
[17:44] <burek> L1nux, that's most probably the bug
[17:44] <burek> so you should update your ffmpeg anyway
[17:44] <Taladan> I just replaced -vpre with -preset, but using superfast as the preset.  Doesn't seem to matter which preset I use (since it's just the video preset it shouldn't affect audio I'd think)
[17:46] <Taladan> I'm beginning to think maybe it's the -threads that I'm using.
[17:46] <burek> Taladan, ok, this takes the a/v input and saves 2 files
[17:46] <burek> one for video and one for audio
[17:46] <Taladan> I have a six core processor and was wanting to distribute the encoding load across it
[17:46] <burek> try removing -threads
[17:46] <burek> or use -threads 1
[17:46] <burek> just to see if it will work
[17:47] <Taladan> yeah, that's how I do the screen capture for my youtube videos so i can just get audio & video seperately.
[17:47] <Taladan> what I use to stream: https://docs.google.com/file/d/0B7JCjpvY2cExNTJmZDRjMTgtZjNiZi00ZWQ4LTk3OTktMWJjZTM5ZTY3Zjg3/edit
[17:48] <Taladan> ignore the commends at the bottom of the file, that was for a video I put on yt on how to stream to jtv with ffmpeg
[17:48] <Taladan> s/commends/comments
[17:49] <burek> Taladan, your ffmpeg also might be too old
[17:49] <burek> I don't see its output
[17:49] <burek> so I can't tell
[17:49] <burek> but in 90% of cases, updating ffmpeg did the job
[17:50] <Taladan> burek - that was an older version (in that last script)  But I recently updated to kubuntu 12.04
[17:50] <burek> with multimedia projects like ffmpeg, that change rapidly
[17:50] <Taladan> weird thing is, in the old version, I didn't get the crackling
[17:50] <burek> your best bet is to use git source version
[17:50] <burek> and compile
[17:50] <Taladan> it only started when I upgraded to ubuntu 11.10 then to 12.04
[17:50] <Taladan> (k)ubuntu
[17:51] <Taladan> currently have ffmpeg version 0.8.1-4:0.8.1-0ubuntu1
[17:52] <burek> there is 0.10 already..
[17:57] <cpglsn> hi there
[17:58] <cpglsn> i'm having a little problem converting a file (this http://pastebin.mozilla.org/1647432) into .mp4 file. as you can see http://pastebin.mozilla.org/1647430
[17:59] <cpglsn> [libvo_aacenc @ 0xf65f30] Unable to set encoding parameters
[17:59] <cpglsn> Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height
[18:00] <cpglsn> but i did not put any parameters ... so, what's wrong?
[18:00] <L1nux> burek, is because ffplay try to 'estimate duration from bitrate' How to disable this ?
[18:00] <burek> cpglsn, most probably you want this: ffmpeg -i War.avi -c copy War.mp4
[18:00] <Taladan> would it help if I uploaded a vid with an example of the popping/crackling I'm talking about?
[18:01] <burek> or not :)
[18:01] <burek> Taladan, first update your ffmpeg
[18:01] <burek> no point of analyzing something
[18:01] <burek> if the bug is already fixed
[18:01] <cpglsn> burek: http://pastebin.mozilla.org/1647434
[18:01] <burek> L1nux,
[18:02] <burek> search for analyzeduration
[18:02] <burek> ffmpeg -analyzeduration 0 ...
[18:02] <Taladan> I take it there's no .deb for the latest ffmpeg
[18:03] <burek> cpglsn, try updating your ffmpeg too
[18:03] <burek> Taladan, not sure..
[18:03] <L1nux> burek, Thanks :))
[18:04] <burek> L1nux, does it work?
[18:04] <cpglsn> cpglsn: to 0.10.3 ?
[18:04] <L1nux> is work fastly
[18:04] <L1nux> :D
[18:04] <burek> :)
[18:04] <burek> :beer: :)
[18:04] <burek> cpglsn, from git
[18:04] <cpglsn> burek: from git? wow, but is this a known problem ?
[18:04] <burek> http://ffmpeg.org/bugreports.html
[18:04] <burek> "FFmpeg is in a state of perpetual development and we do not currently have the person power to backport fixes to official releases. As such, if you wish to query or report a bug, you must try with the latest development branch revision of FFmpeg to confirm the issue still exists."
[18:05] <cpglsn> uhm, ok, i'll see. Thanks burek =)
[18:05] <burek> official releases are provided for convenience, but if something doesn't work, either wait for a bug fix in the next release or use the git version and report a bug
[18:05] <burek> which will be fixed very soon
[18:06] <burek> comparing to releases :)
[18:06] <L1nux> hehe, "analyzeduration" not found in ffplay man page
[18:06] <L1nux> :P
[18:06] <burek> L1nux, I just realized the same :D
[18:06] <burek> it just tells ffmpeg/ffplay how long to buffer the input to analyze it and guess the format
[18:06] <burek> the value used is in microseconds
[18:06] <burek> 1/1.000.000 of second :)
[18:11] <L1nux> burek, "-analyzeduration 0" is fine, no need to analyze more :)
[18:12] <burek> I agree :)
[18:26] <Sagitt> hi
[18:27] <Sagitt> i've a server with ubuntu server 12.04, and i need to enable the x264 support in ffmpeg, there is a way to enable it directrly from sources? or without unistall it?
[18:27] <burek> if your distribution didn't compile ffmpeg with libx264 support
[18:27] <burek> then you need to compile ffmpeg yourself
[18:28] <Sagitt> i understand
[18:29] <Sagitt> my distribution tell me that now, ffmpeg is only for compatibility
[18:29] <burek> what else did they tell you?
[18:29] <Sagitt> i'm using zoneminder and in options i've added the path /usr/bin/ffmpeg
[18:29] <Sagitt> if i add the path /usr/bin/avconv is the same?
[18:30] <burek> did they suggest you to use the ffmpeg's fork, named libav?
[18:30] <Sagitt> avconv
[18:30] <burek> I see..
[18:30] <burek> well, you can always change the distribution
[18:30] <burek> if they force you to do something
[18:31] <Sagitt> no problem to this
[18:31] <burek> but, to avoid that hassle, just compile your own ffmpeg, it's not that hard
[18:31] <Sagitt> i want to install ffmpeg with z264 support :p
[18:31] <Sagitt> yes i know
[18:31] <burek> let me see
[18:31] <Sagitt> but i've another problem
[18:31] <Sagitt> (sorry for my bad english)
[18:31] <burek> http://ffmpeg.gusari.org/viewtopic.php?f=25&t=14
[18:31] <Sagitt> i've installed ffmpeg and zoneminder
[18:31] <burek> that'll do
[18:32] <Sagitt> but, if i want to unistall the source installed ffmpeg
[18:32] <Sagitt> it force me to unistall zoneminder
[18:32] <Sagitt> but if i unistall zoneminder, i've it off, and i've to reconfigure it
[18:32] <burek> well, compile zoneminder too
[18:32] <Sagitt> there is a way to unistall source ffmpeg without unistall zoneminder?
[18:32] <burek> not on that distribution
[18:33] <burek> im afraid
[18:33] <Sagitt> and i cant overwrite the installed ffmpeg right?
[18:43] <Taladan> so...doing the compile.  Now my OpenShot doesn't support mp4 format and the audio is still crap.
[18:44] <Taladan> so, new version of ffmpeg didn't fix it, just made it worse.
[18:49] <ShinyObjects> burek: After a weekend of being out of the office there are two channels that set off my "beer" filter: #debian and #ffmpeg
[18:49] <ShinyObjects> Congratulations
[18:51] <casso> Is there a way to append frames to .avi file, everytime I call ffmpeg?
[18:57] <zap0> i thin kavi keeps some details in the tail
[18:57] <zap0> casso, so probably not.
[18:57] <casso> damn
[18:57] <casso> I'll have to generate hundreds of frames then
[19:09] <Taladan> aaand now I'm in dependancy hell.
[19:12] <burek> Taladan, what libs do you need with ffmpeg?
[19:13] <burek> ShinyObjects :)) :beer: :)
[19:13] <burek> casso, what exactly is your scenario?
[19:18] <Taladan> not sure other than liblamemp3 and libx264
[19:18] <burek> those are small, just compile them too
[19:18] <Taladan> those are the ones that i use the most...working on trying to rescue my system atm though so I can't do much testing.  I knew better than to try and compile ffmpeg...*sighs*
[19:19] <burek> and if you have multi-cores use make -j cores+1
[19:21] <Taladan> gotta restart
[19:24] <casso> I want to add 1 second duration of image to movie. What -vframes and -r  must I specify, if I want to have 25 fps and 1 second duration of movie clip
[19:25] <newl> you need ffmpeg libs to compile x264 (chicken egg omlet thing)
[19:26] <casso> ?
[19:26] <newl> compile ffmpeg without x264 then compile x264 and then compile ffmpeg with x254 - way it use to be maybe they 'fixed' it ?
[19:31] <burek> casso, http://ffmpeg.gusari.org/viewtopic.php?f=25&t=39
[19:31] <casso> burek: tnx
[19:32] <casso> burek, are you from Slovenia?
[19:32] <burek> serbia
[19:58] <lesshaste> hi
[19:58] <lesshaste> can ffmpeg play ttp://acstream.princeton.edu:8080/ramgen/blackboard/cs/additive_combinatorics/1_luca_trevisan_350k.rm ?
[19:58] <lesshaste> using mplayer you would do
[19:58] <lesshaste> mplayer -playlist http://acstream.princeton.edu:8080/ramgen/blackboard/cs/additive_combinatorics/1_luca_trevisan_350k.rm
[19:58] <lesshaste> so is there a playlist equivalent?
[20:01] <newl> can ffmpeg now play files? when did you add that
[20:02] <Bombo> hm how do i set an audio delay? with -itsoffset offset ? when i play the avi in smplayer a and v are out of synch, but when i set the delay to -1000 (with '-' in smp) its ok
[20:03] <Bombo> i tried with 'ffmpeg -i video.avi -i audio.mp3 -codec copy -itsoffset -00:00:01 muxed.avi' but its still not synched
[20:05] <burek> lesshaste, just type ffplay rtsp://128.112.131.181:554/blackboard/cs/additive_combinatorics/1_luca_trevisan_350k.rm
[20:06] <lesshaste> burek, [rtsp @ 0x863e680] UDP timeout, retrying with TCP
[20:06] <lesshaste> Segmentation fault
[20:06] <burek> update your ffmpeg
[20:06] <burek> it's probably old
[20:06] <lesshaste> ffplay 0.7.3-4:0.7.3-0ubuntu0.11.10.1
[20:06] <lesshaste> not that old!
[20:06] <sacarasc> Very old.
[20:06] <sacarasc> It's 0.10 now...
[20:07] <burek> Bombo, it does matter where do you put -itsoffset
[20:07] <burek> before/after input(s)
[20:07] <burek> so play with it
[20:07] <burek> 0.7 is way too old
[20:07] <Bombo> burek: hm
[20:10] <lesshaste> sacarasc, ok... I meant more that the version is many years after the video format was supported
[20:11] <lesshaste> sacarasc, so I am not sure that anyone would have worked on it since then
[21:54] <Yuhjn> is there a way to get ffmpeg to truncate an mp3 audio file as I add it to a video?
[21:55] <Yuhjn> I'm actually doing a concat: on a bunch of mp3's but I need to trucate some of them
[23:00] <Sagitt> anyone use httpsegmenter?
[23:30] <Motoko-chan> I'm having some problems with the mp video filter, specifically stereo3d. Does anyone have experience with it?
[23:30] <sware> is there a way to generate a config.h for a windows system?
[23:31] <sware> through the mingw process of building?
