[00:33] <pasteeater> nextime: you mean you want two output files (one video only, one audio only) from one input?
[00:52] <Guest90713> hey guys
[00:53] <Guest90713> i installed macports, then did sudo port install ffmpeg
[00:53] <Guest90713> and my terminal isn't displaying any new lines
[00:53] <Guest90713> but the last lines say "activating ffmpeg @0.7.8_0" and something about non free GPLed stuff
[00:53] <Guest90713> what should i do? ><
[00:56] <sacarasc> Is the CPU being used?
[00:57] <Guest90713> idk
[00:57] <Guest90713> how can i tell
[00:57] <Guest90713> and does it matter
[00:57] <sacarasc> If it's using your CPU, then it's compiling.
[00:57] <sacarasc> Otherwise something went wrong.
[00:58] <sacarasc> Also, 0.7.8 is very old.
[00:58] <sacarasc> It's up to 0.10, now.
[00:58] <Guest90713> this is what i got http://pastebin.com/i0c3eb0Z
[01:03] <Freakshow> well, macports isn't up to date by any means...
[01:03] <Freakshow> maybe ffmpeg-devel instead...
[01:04] <Freakshow> I've recently confirmed that macports is exactly what Guest90713 has referenced
[01:04] <Guest90713> huh?
[01:04] <Guest90713> wowow what do i have to do
[01:05] <Freakshow> hmm... I'm not entirely sure, maybe ping the macports maintainer?
[01:05] <Freakshow> ask them to update? I don't know if that's an option
[01:06] <Guest90713> can i close my terminal and come back tomorrow it's 1:06 am here
[01:06] <Guest90713> without breaking any packages or whatever of course
[01:10] <Guest90713> guys i gtg
[01:41] <Freakshow> ok
[02:05] <nextime> argh.
[02:05] <nextime> [mp4 @ 0x25ba4a0] muxer does not support non seekable output
[02:05] <nextime> how to convert for a stream that has to be embed on html5 by <video> tag?
[02:06] <sacarasc> The easiest way is ffmpeg -i input output.webm
[02:06] <Shimmy> Hello!
[02:06] <Shimmy> Anyone willing to help me with my issue?
[02:06] <Shimmy> https://ffmpeg.org/trac/ffmpeg/ticket/747
[02:06] <nextime> sacarasc : i have to support ALSO webm
[02:07] <sacarasc> Webm plays in <video> tags, so win/win!
[02:07] <nextime> sadly not all browser support webm or theora
[02:07] <nextime> sacarasc : no, webm play in <video> tags if you are using firefox, opera, chrome
[02:07] <nextime> but not with IE or safari
[02:07] <nextime> not on iphone
[02:07] <sacarasc> H264/? in MP4 is the other one?
[02:08] <nextime> mp4 is a container
[02:08] <nextime> and inside mp4 the codec usually is h264
[02:08] <sacarasc> That's why I said *IN* MP4.
[02:08] <pasteeater> yeah, sacarasc. duhhh.
[02:08] <sacarasc> And what audio?
[02:08] <nextime> aac
[02:08] Action: pasteeater annoys sacarasc
[02:10] <sacarasc> ffmpeg -i input -acodec aac -b:a 60k -vcodec libx264 -preset blah -profile:v blah2 -b 500k output.mp4 && qtfaststart output.mp4 output2.mp4
[02:10] <nextime> sacarasc : it doesn't work if you are using an output that is a pipe
[02:11] <nextime> it's a realtime converted network stream
[02:11] <nextime> i can't do it on a file
[02:11] <pasteeater> this is why you use pastebin to provide your complete command and the complete console output when you encounter errors
[02:11] <sacarasc> Or say exactly what you want first.
[02:12] <pasteeater> although we can becoming more psychic with experience...
[02:12] <nextime> http://pastebin.com/sGnLK9ED
[02:12] <sacarasc> I suppose the [mp4 @ 0x25ba4a0] muxer does not support non seekable output should have given it away that you were trying to stream ffmpeg produced mp4...
[02:12] <nextime> sacarasc: exactly
[02:13] <nextime> and now, as the mux can't work on a pipe
[02:13] <nextime> i need to find an alternative container
[02:13] <nextime> that work on <video> for IE and safari
[02:13] <nextime> and iphone and ipad
[02:29] <pasteeater> vo-aacenc 0.1.2 released today, and opencore-amr & vo-amrwbenc, but who gives a rat's ass about those.
[02:29] <pasteeater> ...not that i really care for vo-aacenc.
[02:44] <nextime> ok, webm, ogg, and flv for flash are working
[02:44] <nextime> only the mp4 issue remain...
[02:52] <Freakshow> mp4, who gives a rat's ass about that
[02:53] <Freakshow> >.<
[02:53] <assem> trying to compile under cygwin and at linking avdevice i get undefined references to _sws_scale, _sws_freeContext, ..., _swr_convert, _swr_free
[02:54] <assem> any help? using both ffmpeg-0.10 release and the git repo
[02:56] <assem> hm nm i appear to have just fixed my problem; added swresample and swscale to avdevice/Makefile's FFLIBS=...
[06:22] <maujhsn> Would enabling the enviromental variable  "--shlibdir=DIR"  in ffmpeg be the way to go for a new plug-in like "the gimp-plugin which is independent of ffmpeg?
[06:27] <maujhsn> Mavrik  Any thoughts on my topic?:)
[06:28] <mgeary> hi folks
[06:28] <mgeary> is there a way to get libfaac to not have a problem with mono audio?
[09:59] <pom> This issue http://ffmpeg.org/trac/ffmpeg/ticket/336 is marked as fixed. How can I figure out if this resolution is included in the git repo, and if not, how can I contact "michael"?
[10:03] <ubitux> it's most likely in; did you expect a similar issue?
[10:05] <pom> ubitux: Don't understand what you mean by expect, but I seem to have this exact symptom now.
[10:06] <pom> I just noticed that it can be worked-around by specifying format wih -f "mp3" before the -i.
[10:06] <ubitux> could you share the sample?
[10:07] <pom> Yes. Just wanna make sure I'm using a recent version on this machine. Brb.
[10:09] <pom> My version is built at feb 1st, but it's only version 0.7. I'm gonna have a look at this first and get back to you if I still experience it.
[10:29] <dipanjan> hi, i have converted some m4v files to vob files using ffmpeg. but dvdauthor says No VOBus found. Can anyone help? used `ffmpeg -y -sameq -i "$i" -target pal-dvd "$name.vob"`
[11:48] <mrfree> hi all
[11:48] <mrfree> how can I show all available presets in ffmpeg?
[11:48] <mrfree> I read something about "x264 --help" but I don't know... well... where use it :) ffmpeg x264 --help doesn't work
[12:00] <mrfree> using strace I've found the problem... ffmpeg search for .ffpreset file but it should use .avpreset, shouldn't it?
[12:01] <mrfree> adding a symlink works
[12:03] <JEEB> libx264 has its own internal presets now
[12:03] <JEEB> which should be used
[12:04] <JEEB> as they're kept up-to-date on the libx264 side
[12:04] <JEEB> http://mewiki.project357.com/wiki/X264_Settings#preset
[12:04] <JEEB> if you have no x264 binary, you can check this listing for a list of presets
[12:06] <Mavrik_> morning everyone :)
[16:06] <Iszak> Is there any progress on supporting Intel QuickSync in FFMPeg?
[17:35] <mgeary> hi folks
[17:36] <mgeary> so, i'm still struggling with some sort of aspect ratio issue. Quicktime is interpreting the video dimensions differently than ffmpeg. Would manually changing the pixel aspect ratio possibly solve this issue?
[18:37] <minihydra> Im trying to downscale fullhd screencast, 4x (2x width and 2x height) to get smaller filesize, however i get considerably worse quality and file size remains almost the same... Maybe someone could give me some advice?
[18:41] <minihydra> http://pastebin.com/EVgvP9xt some output
[18:42] <minihydra> i specify -q:v 1, so according to manual this should imply vbr, but while encoding q holds about 27, so this seems strange, and how can file take almost same space with 4x smaller resolution and lower quality....
[20:59] <kevin> so if i use ffmpeg to generate ntsc-dvd compatible mpgs (using -target ntsc-dvd), can i join the mpgs using 'cat' to create a larger mpg for use in dvdauthor?
[21:00] <kevin> or do i have to re-encode the joined mpg file? (not sure about headers joining from the individual files, etc)
[21:03] <Mavrik> afaik .mpg files can be joined
[21:05] <kevin> yeah, that's what the ffmpeg FAQ says regarding joining multiple video files (convert each to mpg, cat the mpgs, convert back to original format) , so i'm thinking it should work. i'll just have to try it out
[21:07] <kevin> second question: can you hardcode subtitles using ffmpeg into the actual video stream? i read somewhere that it cant and i'd need to use like mencoder. i'm looking at ffmpeg man pages and all subtitle-related options seem to talk about the subtitle stream, not actually writing it in the video stream
[21:12] <Mavrik> kevin, check libavformat documentation for a subtitle video filter
[21:12] <Mavrik> but I doubt it's possible at the moment
[21:18] <ubitux> kevin: with libass video filter you can
[21:18] <ubitux> it requires you to build with --enable-libass, and also have the subtitles in a file, in ASS format
[21:18] <ubitux> it's meant to be a temporary solution for hardsub, but it should work
[21:26] <kevin> hrmmm alright thanks
[21:38] <VooDooNOFX_> kevin, ffmbc can burn in subtitles
[21:43] <vadim_> hi, guys
[21:45] <vadim_> ffmpeg hangs on reading from udp source... it throws a "circular_buffer: OVERRUN" and hangs after a few seconds... have somebody solved this?..
[21:48] <pasteeater> vadim_: i know nothing of udp, but generally when you encounter an error your command and the complete console output is useful. use a pastebin service.
[21:49] <rexbron> Hey everyone, ffmpeg is giving garbage output on some ProRes 4444 samples I have and ffplay is also wacked. Is ProRes4444 suported by the decoder?
[21:50] <rexbron> Also, does ffmpeg support copying of mov timecode tracks into other movs/wrappers?
[22:04] <PeraZdera> Hi
[22:06] <PeraZdera> can anyone help me with circular buffer overun problem? I want to transcode live mpegts to h264 but after some time I get circular buffer overrun message and ffmpeg get 100% cpu usage
[22:06] <PeraZdera> here is pastebin
[22:06] <PeraZdera> http://pastebin.com/9Y9ZNPhD
[22:07] <vadim_> pasteeater: i was talking about the same problem as PeraZdera does...
[22:10] <PeraZdera> vadim: which is circular buffer overun?
[22:10] <cbsrobot> rexbron: can you share a prores 4444 sample ?
[22:10] <rexbron> cbsrobot: sure
[22:10] <cbsrobot> a few seconds is enough ....
[22:11] <vadim_> PeraZdera: this is a bug... (
[22:11] <rexbron> cbsrobot: the file has a lot of preroll (bars and a sync countdown), should it be actual image data?
[22:11] <cbsrobot> rexbron: yes please
[22:11] <cbsrobot> btw. I think copying timecode is not well supportet
[22:12] <cbsrobot> but try ffmbc
[22:12] <PeraZdera> vadim_: are you sure? I can't find any open bug about this the last one is close in 2008 IIRC
[22:12] <PeraZdera> vadim_: s/close/closed/
[22:12] <vadim_> PeraZdera: https://ffmpeg.org/trac/ffmpeg/ticket/609
[22:13] <vadim_> PeraZdera: and it is open for 4 months :(
[22:13] <rexbron> cbsrobot: should I upload it to incomming or my own hosting?
[22:14] <cbsrobot> i don't care
[22:14] <vadim_> PeraZdera: i have tested with latest ffmpeg 0.10, the problem is still there
[22:14] <cbsrobot> maybe soemwhere I can dl it
[22:14] <cbsrobot> if I remember well ffmpeg even crashes trying to copy tc tracks in mov
[22:15] <cbsrobot> I was working on it a few weeks ago - but I don't have time to finish it atm :-(.
[22:16] <cbsrobot> relaxed: are he samples form an alexa ?
[22:16] <PeraZdera> vadim_: hmm I am using the latest version from git repo and still the same bug, let me see if I can find the older bug I have found to be reported as fixed...
[22:18] <vadim_> PeraZdera: i have analyzed all major versions starting with 0.6.1... each introduces new modifications but the result is the same :(
[22:19] <rexbron> cbsrobot: No, it is the master from a short film I shot
[22:19] <vadim_> PeraZdera: the ticket i have referenced, IMHO, describes the problem the best possible...
[22:19] <cbsrobot> what device recorded it ?
[22:20] <PeraZdera> vadim_: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=7c4e4c6a0664bf668f4b7766a06f30096e0601f3
[22:20] <vadim_> pasteeater: who should we pray to, to solve this problem ASAP?.. i'm not the only person which need this module stable...
[22:21] <rexbron> cbsrobot: Created by apple compressor (From Final Cut Studio 3 iirc)
[22:22] <cbsrobot> hmm - why 4444 then ?
[22:26] <rexbron> cbsrobot: Onlining from HDCAM SR after colour grading
[22:26] <rexbron> I think
[22:26] <rexbron> it was about three years ago
[22:26] <rexbron> :P
[22:27] <rexbron> cbsrobot: Noticed something odd
[22:27] <rexbron> cbsrobot: http://pastebin.ca/2120881
[22:28] <rexbron> cbsrobot: copying both streams results in the new file probing as the wrong pixel format
[22:29] <rexbron> also, duration is incorrect
[22:29] <vadim_> PeraZdera: what version of ffmpeg do you use?
[22:30] <cbsrobot> rexbron: not sure qhat is going on
[22:30] <cbsrobot> there are now 2 enoders and 2 decoders in ffmpeg ...
[22:30] <pasteeater> vadim_: if you think it's a bug then check the reports here: https://ffmpeg.org/trac/ffmpeg/
[22:30] <cbsrobot> I need to run
[22:31] <cbsrobot> just post the link and I'll see later
[22:31] <pasteeater> if you don't see an existing bug related to your issue(s) then make a new, detailed report
[22:32] <vadim_> pasteeater: this one describes the situation https://ffmpeg.org/trac/ffmpeg/ticket/609
[22:33] <rexbron> cbsrobot: http://files.aehunter.net/DIVISION_SAMPLE.mov
[22:34] <pasteeater> vadim_: looks like they are using ffmpeg programtically, and not ffmpegcli. you might want to post a response to the report with a cli example so others can duplicate the issue easier.
[22:34] <pasteeater> if you believe it's the same issue you are experiencing
[22:38] <vadim_> pasteeater: ok... i'll open a new ticket with the console listing... but IMHO it's the same trouble... btw, take a look at this http://pastebin.com/9Y9ZNPhD I'm going to send  something similar...
[22:39] <vadim_> pasteeater: the link i sent you was posted by PeraZdera
[22:46] <rexbron> cbsrobot: reported as https://ffmpeg.org/trac/ffmpeg/ticket/1015
[22:51] <PeraZdera> vadim_: can you please post your pastebin link? I would like to see how ffmpeg was compiled
[22:52] <vadim_> PeraZdera: compiling right now... will post it in 10-15 minutes
[22:56] <PeraZdera> vadim_: Do you use live mpeg2-ts or you are transcoding file?
[22:57] <vadim_> PeraZdera: live
[22:58] <TlatoSMD> hi there
[22:58] <TlatoSMD> hey, I'm trying to encode an SRT subtitle into a file
[22:58] <TlatoSMD> so far, I've been using VDub and Avidemux, to no avail
[22:58] <TlatoSMD> how do I do with ffmpeg?
[22:59] <TlatoSMD> in any case, I suppose hard subs (that are always on) will do
[22:59] <kevin> TlatoSMD - are you trying to create it as a new stream or overlay/bake it in the video stream?
[23:00] <TlatoSMD> the process will also involve transcoding it from DivX to x264, so I suppose that makes it a new stream?
[23:00] <kevin> i asked about the latter earlier today and got this response: https://gist.github.com/1887712
[23:02] <TlatoSMD> sounds like I'll need an ASS file in the first place?
[23:03] <undercash> hi
[23:03] <undercash> what s max crf value?
[23:06] <kevin> TlatoSMD: for the hard subs i believe so. i personally haven't tried it yet
[23:11] <CarlFK> melt (build on ffmpeg libs) uses acodec=libmp3lame ... vcodec=libx264  which no longer works.  melt dev says "The codec names probably changed."  anone know what I should be using ?
[23:12] <vadim_> CarlFK: do you use '=' sign in your cli?
[23:13] <CarlFK> yes
[23:13] <vadim_> replace with ' ' (space)
[23:13] <CarlFK> that was cut/paste from what I run at the $ prompt
[23:13] <CarlFK> k
[23:22] <vadim_> PeraZdera: http://pastebin.com/0gK9JSw4 here it is... sorry for the length...
[23:27] <tbws> hi everyone
[23:28] <tbws> i'm having a problem compiling ffmpeg on lucid. Apparently it cannot find my installation of libaac
[23:28] <tbws> 2 secs im just uploading my log
[23:31] <CarlFK> vadim_: melt syntax wants the  =   replaced with space I get:   Failed to load "acodec"; Failed to load "libmp3lame"
[23:31] <sacarasc> CarlFK: Full command line and full output to a pastebin, please.
[23:34] <CarlFK> http://pastebin.com/vbR9XZgv  [consumer avformat] audio codec libmp3lame unrecognised - ignoring
[23:35] <tbws> http://textuploader.com/?p=6&id=OlQSI : just to recap i'm having problems compiling ffmpeg on lucid as it can't find libfaac
[23:35] <vadim_> CarlFK: sorry, my mistake... never used melt...
[23:38] <vadim_> tbws: have you installed libfaac-dev package?..
[23:38] <tbws> yep, its reffered to as libfaad-dev on lucid
[23:40] <vadim_> tbws: i,ho, you're wrong... install libfaac-dev... follow this http://ubuntuforums.org/showpost.php?p=9868359&postcount=1289
[23:41] <tbws> couldn't find package
[23:41] <tbws> i don't think i am
[23:44] <vadim_> tbws: take a look here http://pastebin.com/72bv5RVT this from my machine
[23:46] <pasteeater> undercash: 51 is the highest crf value (for 8-bit x264 at least)
[23:47] <undercash> hi pastee  thx
[23:47] <tbws> ty vadim_ what does your sources.list look like?
[23:49] <pasteeater> tbws: maybe a better quesiton is what does _your_ sources.list look like?
[23:55] <vadim_> pasteeater: lol, it's not a big deal to share the sources.list )))
[23:55] <vadim_> pasteeater: any way, thx )
