[01:00] <kcm1700> Is there a way to pass so-called 'extradata' to mpeg4-video codec after avcodec_open# ? [01:00] <kcm1700> codec_id is AV_CODEC_ID_MPEG4 [02:42] <kcm1700> no one here? T.T [02:57] <llogan> try libav-user mailing list if you don't get an answer here [03:14] <kcm1700> thank you. is it ok to use libav-user mailing even if I use ffmpeg? [03:46] <rcombs> does ffmpeg not support building with SDL2 yet? [07:05] <sisco_dreamber> hi all [07:05] <sisco_dreamber> any one here able to help me plz [08:34] <zap0> just ask [08:35] <zap0> also, good luck, you said like a moron.. 'plz' [09:12] <sisco_dreamber> zap lol [09:12] <sisco_dreamber> well its more ruby [09:12] <sisco_dreamber> so im at ruby lobby [10:37] <matthias_> Can sb help me with some pulseaudio and ffmpeg scripting? [10:40] <saste> matthias_, don't ask to ask, just ask [12:13] <vvu|Log> hello! i am trying to save some images from an RTSP stream and i get "unimplemented RTP/JPEG restart marker header". from what i see this comes from libavformat/rtpdec_jpeg.c [12:13] <vvu|Log> the id of the jpeg decoder params is > 63 *don't really know what this means* [14:43] <feep> hi, can I use ffmpeg to convert a high-fps video (like 120) to a low-fps motion-blurred video? [15:08] <zap0> probably, but you really shouldn't think of ffmpeg as an fx thingy [15:08] <zap0> the rate conversion yes. blur.. maybe [16:56] <benbro2> when recording video from screen, how can I know the timestamp of the first frame? [17:09] <zap0> record the time in teh first frame. [17:10] <benbro2> zap0: how? [17:10] <benbro2> I want to use something like "ffmpeg -f dshow -i video="UScreenCapture" output.flv" [17:10] <benbro2> can I get the timestamp of the first frame from output.flv? [17:16] <viric> -vf showpts [19:12] <Xaser> hiho [19:13] <Xaser> I have a quick question about using ffmpeg to split audio streams. [19:14] <Xaser> Basically I want to losslessly extract a one minute sample from a) the original ac3 file, b) the aac encoded (nero) version of that original [19:16] <Xaser> I've been using this command: ffmpeg -i "org.ac3" -ss 00:02:30 -t 00:01:00 "Sample1.ac3" and ffmpeg -i "enc.m4a" -ss 00:02:30 -t 00:01:00 "Sample2.m4a" [19:17] <Xaser> now.. is that the correct way to do this and will the extracted sample2 sound different compared to the reencoded sample1 ? [19:28] <Xaser> anybody? [19:54] <clever> Xaser: i think that will re-encode the tracks by default [19:54] <Xaser> hm [19:54] <clever> you probly want to add -acodec copy [19:55] <Xaser> okay [19:55] <Xaser> i was wondering why the file sizes of all three samples turned out the same^^ [19:56] <Xaser> anything else I should take into concideration? [20:18] <benbro2> when starting a screen capture from the command line, how can I stop it? [20:18] <benbro2> just Ctrl+C ? [20:18] <benbro2> or will it leave a corrupted video? [20:28] <Xaser> it won't affect the input file, thats for sure [20:28] <Xaser> however it won't create a valid video file [20:29] <Xaser> @benbro2 that is [20:30] <relaxed> benbro2: did you try 'q'? [20:31] <benbro2> I need something like "ffmpeg -f dshow -i video="UScreenCapture" output.flv" under windows [20:31] <benbro2> 'q' is under linux? [20:32] <relaxed> Try it. You can also use -t $time after the input [20:34] <benbro2> relaxed: I need to stop it dynamically [20:34] <benbro2> maybe from powershell [21:00] <Davym123> I probably the 1000th person to be here for a problem, so first of all.. Sorry! Anyway, there is a php script that requires ffmpeg with xvid coddec support but I can't get it to work..! [21:00] <Davym123> http://prntscr.com/2f7mku [21:00] <Davym123> Look [21:01] <Davym123> http://prntscr.com/2f7n9a [21:11] <Davym123> Any idea, anyone? [21:33] <Davym123> Nobody here? :D [21:33] <llogan> Davym123: why are you trying to compile code from SVN? [21:33] <llogan> ffmpeg has been using git for a few years now at least [21:33] <Davym123> So how do I enable the xvid ? [21:34] <llogan> your version of ffmpeg is unsupported here [21:34] <Davym123> All the rest worked fine using the auto installer [21:34] <Davym123> Oh.. [21:35] <Davym123> So what the the recommended steps to fix this [21:35] <Davym123> are* [21:36] <llogan> 1. get recent ffmpeg via http://ffmpeg.org/download.html [21:36] <llogan> 2. mak sure /tmp does not have noexec [21:37] <llogan> your /tmp issue probably has nothing to do with ffmpeg [21:37] <Davym123> should I clean everything in my /tmp? [21:37] <llogan> no [21:38] <llogan> use pastebin.com or similar to show the output of: mount | grep noexec [21:38] <llogan> and also: ls -alh /tmp [21:39] <Davym123> http://pastebin.com/aJtefMuc [21:40] <Davym123> http://pastebin.com/Qk3vW3q7 [21:40] <llogan> your /tmp is mounted as noexec. why? [21:41] <Davym123> I don't really do stuff in my ssh [21:42] <llogan> what is your distro? [21:42] <Davym123> I had an indian installing security on my server though [21:42] <Davym123> distro? [21:42] <llogan> an indian? [21:42] <llogan> an indian from india, or a Native American? [21:42] <Davym123> India [21:43] <Davym123> Centos 5 btw [21:43] <Davym123> 6.5* [21:43] <Davym123> 6.4 [21:43] <Davym123> derp [21:43] <Davym123> CENTOS 6.4 x86_64 [21:44] <llogan> remount /tmp without noexec or set the TMPDIR environment vairable to another directory and make sure it is not mounted with noexec [21:45] <Davym123> Whoa [21:45] <Davym123> I guess I need to hire someone [21:45] <Davym123> :D [21:45] <clever> sudo mount /tmp -o remount,exec [21:45] <clever> this will force it to have the exec flag without loosing any data [21:45] <Davym123> done [21:45] <clever> then just try whatever failed in the first place [21:46] <Davym123> Well, installing Xvid codec [21:46] <llogan> but use ffmpeg from git, not that old, ancient, graybeard code from SVN [21:46] <Davym123> https://trac.ffmpeg.org/wiki/CentosCompilationGuide [21:46] <Davym123> use this? [21:46] <llogan> sure [21:47] <llogan> also, why do you want libxvid support? ffmpeg has a native mpeg-4 part2 video encoder. [21:47] <llogan> "-vcodec mpeg4" [21:47] <Davym123> It's for a php script that I found [21:47] <llogan> if you found some food on a sidewalk, would you eat it? [21:48] <Davym123> No [21:48] <Davym123> :D [21:48] <llogan> and who uses that format these days anyway? [21:49] <Davym123> The script, I'm not good at php coding so I can't change it [21:49] <Davym123> and the script is kinda good [21:56] <Davym123> Need to updatte my YASM [21:57] <Davym123> And I did, but still says i'm running older version, do I need to restart something, [21:57] <Davym123> ? [22:09] <llogan> Davym123: what is telling you that you are running an older version of what? [22:09] <Davym123> yasm [22:10] <Davym123> Found yasm 1.1.99.HEAD [22:10] <Davym123> Minimum version is yasm-1.2.0 [22:10] <llogan> then install a newer yasm [22:10] <llogan> and remove your old one [22:10] <Davym123> Well I followed the instructions but it's still saying that [22:10] <Davym123> Nvm, I'll find a way [22:10] <Davym123> Thanks ^^ [22:10] <llogan> it's probably detecting your old yasm first [22:11] <llogan> i guess [00:00] --- Tue Dec 31 2013
