[00:48] <jerro> Hi, does anyone here know if it's possible to stream webm with ffserver? How do I configure it to do that? [01:08] <shevy> I can use ffmpeg to join several .mp3 files right? [01:11] <treund> cat even [01:22] <Randy_T> I want to use mplayer or mencoder as a source. This works great, except for sources with variable framerate. I can only do video or audio at once so I encode an audio file first, then video, then copy both to an mp4, or I could include the encoded audio while while encoding the video. Mencoder does a decent job with harddup but I still have a video file length of 24:30, and an audio file length of 24:23. So what I really [01:22] <Randy_T> want is some frames to be dropped so video syncs to audio. Would vsync be a solution here and could someone give me an example in this case? The following is my best guess but it drops all the frames: "-vsync -i pipe: -i aud.mp4 -map 0:0,1:0" [01:25] <Randy_T> pipe: being the raw video output from mencoder. aud.mp4 being audio previously encoded with ffmpeg. [03:07] <jerro> Does anyone here know if it's possible to stream html 5 webm with ffserver? If it is, how do I configure it to do that? [07:52] <Arthur_D> for some reason, copying a file with ffmpeg and trimming it at the end with -t left me with no audible sound [07:52] <Arthur_D> I used ffmpeg -i file.mpg -codec copy file2.mpg [07:53] <Arthur_D> when looking at the codec info of the file in VLC, it has many audio channels and it gets more and more while I play the file [07:55] <Arthur_D> so something is wrong, but I don't know how to remedy this unfortunate situation. Care to enlighten me? :) [07:59] <Arthur_D> hm, importing it to PiTiVi works, sound and all... but when opening it in VLC and MPlayer, it doesn't give any sound [09:33] <Arthur_D> still looking for an answer to my audio stream problem [09:39] <sacarasc> Arthur_D: To quote the on join message: [09:39] <sacarasc> ¬ChanServ¬ [#ffmpeg] When asking a question be precise, detailed and patient. If you don't receive a response, try the users mailing list. PASTE TO http://ffmpeg.pastebin.com/ ! If you are asking about CLI usage, paste the complete command and output to the paste bin. [09:42] <Arthur_D> well, it's not like I'm hogging the channel. Noone else has asked for help in the meantime [09:42] <sacarasc> But you've not read it again. [09:42] <sacarasc> Where is the pastebin of the output of ffmpeg? [09:44] <Arthur_D> http://pastebin.com/RMYLff5E well it doesn't show anything wrong as far as I can see [09:45] <Arthur_D> though I guess I better leave that for others to decide :) [09:53] <rfx> Arthur_D: I don't see anything wrong but I'm just a user like you. The only thing I see is that your version about three months old, you might want to update that. What does ffmpeg -i on the new file show? [09:55] <Arthur_D> Duration: 00:10:27.99, start: 1.000000, bitrate: 2463 kb/s [09:55] <Arthur_D> Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x480 [SAR 8:9 DAR 4:3], 9000 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc [09:55] <Arthur_D> Stream #0:1[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 320 kb/s [09:55] <Arthur_D> so everything seems to be in order [09:56] <Arthur_D> yet VLC and MPlayer doesn't output any sound [09:57] <rfx> Arthur_D: vlc has a log console somewhere, any output there maybe? [09:59] <Arthur_D> not really, but when comparing the original, working file's "module tree" with the copy, there is no audio output in it [10:00] <Arthur_D> funnily enough, it works all right, sound and everything when importing in PiTiVi video editor [10:00] <rfx> I'd try latest ffmpeg just in case .. [10:05] <Arthur_D> I'll try to upgrade it [10:09] <Cervajz> Hello :) [10:09] <Cervajz> Is it possible to switch off (avoid) continuity_check during openning TS file, please? [10:11] <Cervajz> I am trying to open TS file and the "avformat_find_stream_info" function takes a lot of time [10:35] <Arthur_D> rfx: updated ffmpeg, and the issue prevails [12:00] <Arthur_D> alrighty, kinda fixed my issue [12:01] <Arthur_D> used -target ntsc-dvd -vcodec copy to let it automatically choose audio stream output [12:01] <Arthur_D> and thus, it works [13:12] <Cervajz> Hello [13:17] <Cervajz> How can I tell "avformat_find_stream_info" to do not probe private streams in TS, please? [13:18] <Cervajz> This functions started to read whole TS file when it reaches my private stream [13:18] <Cervajz> Then it takes very long time [13:22] <Cervajz> The private streams are marked as "6" [14:07] <rfx> Arthur_D: thanks for sharing, interesting. [15:06] <Arthur_D> rfx: actually, when encoding with the aforementioned options, I got this in the terminal: Incompatible sample format 's16' for codec 'ac3', auto-selecting format 'flt' [15:07] <Arthur_D> thus suggesting that using -acodec copy tried to use the wrong sample format [15:09] <Arthur_D> anyway, it worked, and I'm happy ;) [16:36] <IchGucksLive> Hi all im from Germany i try to find a way to get a AVCHD file from a MOV to play the video from a camcorder on a panasonic screen [16:36] <IchGucksLive> there are 1000 google finds from MTS to ... but not one to the other side [16:37] <IchGucksLive> ffmpeg version git-2011-11-21-2c28e26 [16:39] <Mavrik> IchGucksLive, um... so you have a AVCHD file and you need to convert it to what exactly? [16:39] <IchGucksLive> no the other way i got a MOV from Kodak Zi8 [16:40] <Mavrik> and you need to make an AVCHD file? [16:40] <IchGucksLive> and i want that to play on a usb stick in a Panasonic flatscreen [16:40] <IchGucksLive> Mavrik: yes [16:41] <Mavrik> hmm... I'm not sure ffmpeg supports that... are your sure your Panasonic flatscreen doesn't support mp4 or something like that? [16:42] <IchGucksLive> it says .ps [16:42] <IchGucksLive> or .mts [16:43] <IchGucksLive> i going to have a look at the handbok [16:44] <IchGucksLive> AVCHD, MPEG2 und DivX as transport straem [16:44] <Mavrik> IchGucksLive, it doesn't seem like ffmpeg supports AVCHD encoding [16:44] <Mavrik> ah. [16:44] <Mavrik> MPEG-2 is ok :) [16:45] <IchGucksLive> the transport stream .ps is the container wright [16:45] <Mavrik> .ps is program stream, transport streams are in .ts usually [16:46] <Mavrik> IchGucksLive, ffmpeg.exe -i d:\Videos\MVI_0014.MOV.MP4 -codec:v mpeg2video -b:v 1500k -codec:a mp2 -b:a 128k test.ts [16:47] <Mavrik> that should create a valid stream for the TV [16:47] <IchGucksLive> im on ubuntu [16:47] <IchGucksLive> thanks [16:47] <Mavrik> you can also use "-codec:v libxvid" to encode to DivX for greater quality [16:47] <Mavrik> (if you have it compiled) [16:47] <Mavrik> change -b:v and -b:a parameters for bitrate for the quality you want [16:48] <IchGucksLive> thanks i try this [16:49] <rfx> Irritating nick :) [17:14] <IchGucksLive> Mavrik: thanks i got the problem that libxvidcore4 is on the git ffmpeg but no -codec:v libxvid in codecs [17:15] <IchGucksLive> http://ubuntuforums.org/showthread.php?t=1540254 i updated from medibuntu [17:15] <IchGucksLive> but still no codec [17:15] <IchGucksLive> do i need to recompile ffmpeg [17:21] <IchGucksLive> do i need to restart the system for this ß [17:21] <IchGucksLive> im going foer a restart [17:28] <rhizmoe> going through the build flags, what's the practical difference between faac and vo_aacenc? [18:37] <danverde> anyone using avformat / avcodec in with their own application? [18:40] <danverde> is there an libav user channel? [19:34] <teratorn> danverde: a lot of people use libavformat and libavcodec in their applications [19:35] <danverde> I am wonder where to ask about a memory leak I get when trying to close my format/codev contexts [19:36] <danverde> codec* [19:36] <danverde> I call avformat_close_input but I still am seeing memory leaks [19:36] <danverde> are there other "close" methods I need to be aware of? [19:37] <teratorn> what is being leaked? [19:37] <teratorn> and how do you know it's leaking? [19:38] <danverde> well, that's not real clear to me. I am developing with MSVC and precompiled libav libraries. [19:38] <teratorn> maybe you need to call avcodec_close() on your AVCodecContext [19:38] <danverde> ahh. I am not doing that yet [19:38] <danverde> I'll look at that [19:38] <teratorn> I suggest developing on a real OS that can run valgrind [19:39] <danverde> yeah. I may have to do that if codec close doesn't fix it for me [19:44] <danverde> @teratron: that was it. thx [21:15] <mcbaine1> Hi there ::: I'm really excited about going to FOSDEM ... I put an advert in the national newspaper to see if anyone else is going and to get in touch etc... Anybody available for abit of travelling / FLOSS advice here atmo. ?? [23:19] <mcbaine1> http://goo.gl/6knuF [23:42] <maujhsn> What has to be enabled to get this screencast command to work? http://pastebin.com/HF9KRCWE [23:44] <microchip_> maujhsn: --enable-libx264 [23:45] <maujhsn> microchip_ I thought so! [23:47] <maujhsn> microchip_ Is libx264 one of those "non-free" medibuntu packages from multi-verse? [23:47] <microchip_> i don't know, i don't use *buntu [23:48] <maujhsn> Can anybody else answer this question? [23:49] <Guest50148> um [23:50] <maujhsn> ummmmmmm! [23:50] <Mavrik> there's no reason you'd need libx264 to make a screenshot O.o [23:50] <Mavrik> you forgot to paste the actual command line you use [23:50] <maujhsn> OK! [23:50] <Mavrik> not to mention your ffmpeg version is beyond ancient [23:50] <cbreak> x264 is non-free? [23:50] <cbreak> maybe because it's GPL [23:51] <Mavrik> no, x264 is GPL [23:51] <cbreak> instead of LGPL like the rest of ffmpeg [23:51] <Mavrik> probably some Ubuntu dev has an "opinion" about patents [23:51] <Mavrik> but IIRC it shouldn't be classified as non-free [23:52] <maujhsn> So how is this command modified? "ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1024x768 -i :0.0 -qscale 1 -acodec pcm_s161e -vcodec libx264 -vpre lossless_ultrafast -threads 0 output.mkv". [23:52] <Mavrik> um [23:52] <Mavrik> what exactly are you trying to achieve? [23:53] <maujhsn> screencast [23:53] <Mavrik> ah. [23:53] <maujhsn> ahhhh! [23:53] <Mavrik> yuck, my mistake, I read "screenshot" -_- [23:53] <maujhsn> screencast [23:54] <Mavrik> maujhsn, anyway, your FFMpeg doesn't have libx264 compiled in and dates back to middle ages [23:54] <maujhsn> and [23:54] <Mavrik> update it to new version that has libx264 support compiled in [23:54] <cbreak> if you want to do live recording, maybe something simple like motion jpeg is ok [23:54] <cbreak> until you later compress it down to something more manageable [23:55] <Mavrik> yea, or that - use mjpeg, since you're not compressing the audio either :) [23:55] <maujhsn> So it is sudo apt-get ? [23:56] <cbreak> you could git clone it :) [23:56] <cbreak> (if you like compiling your software yourself) [23:58] <maujhsn> git clone it...Whats the command? [00:00] --- Sat Jan 21 2012
