[00:29] <pzich> hrm, I'm trying to generate a poster frame from a video using an image sequence export, but the colors seem to vary between the image and the first frame of the video, is there a good way to get these colors to match more closely? http://imgur.com/a/Dss8H
[00:30] <klaxa> i blame color conversion
[00:30] <klaxa> jpeg isn't YUV is it?
[00:32] <pzich> http://pastebin.com/hKjadagB
[00:32] <pzich> I was also trying using yuvj420p for the poster frame, but that didn't seem to have helped
[00:32] <pzich> ah, yes, the console bits
[00:36] <pzich> http://pastebin.com/3sNf7Lpu *
[00:45] <pzich> I think the video is coming out a bit washed out, so I may try to correct that to the jpeg instead of the other way around
[05:17] <Zeranoe1> Is there any way to determine the length of a media file with FFmpeg/ffprobe?
[05:18] <hellangel> Zeranoe1,  try ffmpeg -i <filepath>
[05:20] <Zeranoe1> perfect, duration. How accurate is that?
[05:20] <hellangel> no clue really, i googled that
[05:20] <hellangel> im having issues with avconv and streaming sound, if anyone might be able to help: http://moestaverne.com/media/stuff/avconv.txt

[13:31] <zap0> Hello y'all
[14:36] <pjetr> quick question: can I convert SWF's to any other video file?
[14:37] <pjetr> and hello and everything :)
[14:44] <zap0> maybe.
[17:22] <Erneston> hello
[20:26] <StFS> Hi. Anybody on Ubuntu 13.10 having problems with libx264 vcodec? I'm getting a segfault
[20:34] Action: llogan downloads 13.10
[20:40] <StFS> llogan: http://pastie.org/8440859
[20:42] <llogan> StFS: !fork
[20:42] <llogan> that's a fake ffmpeg and it is not supported here.
[20:43] <llogan> a step-by-step guide to compile ffmpeg on Ubuntu: http://trac.ffmpeg.org/wiki/UbuntuCompilationGuide
[20:43] <llogan> (I haven't tested it on 13.10 yet)
[20:43] <StFS> hmm.. ok
[20:44] <llogan> if you want to continue to use that crappy buggy junk then you'll have to ask for help at #libav
[20:45] <StFS> ok thanks :)
[20:58] <batbat_> hello
[20:59] <batbat_> hello, anybody there?

[21:47] <ericgudmundson> I guys, I have a quick question. I just updated my ffmpeg and when I use a udp stream I start to get errors after a little while saying that a reference frame is not present any one else seeing this?
[21:47] <ericgudmundson> Or that the reference 4 >=2
[21:49] <llogan> ericgudmundson: does the output look ok? did the older ffmpeg do this too?
[21:51] <ericgudmundson> No the older ffmpeg does not do this. The output looks nothing like it. Unfortunately we are using the libraries in a propitiatory system and we were using 0.9 and it works fine. the move to 2.0 is when the problem became prevalent. One of my coworkers did run it with the ffmpeg program and it came up after 6 hours where ours comes up after 30 minutes
[21:51] <ericgudmundson>  It does ruin the stream that is being encoded.
[21:53] <ericgudmundson>  let me see if I can get the exact command he ran the test with.
[21:53] <llogan> could be a regression
[21:54] <ericgudmundson>  That is what I was thinking. have you seen anything like that the error is [h264 @ 0x2f9cc00] cabac decode of qscale diff failed at 79 14
[21:54] <ericgudmundson> [h264 @ 0x2f9cc00] error while decoding MB 79 14, bytestream (73877)
[21:55] <ericgudmundson>  and this is usually accompanying it :[h264 @ 0x2f0a2e0] Reference 2 >= 2
[21:56] <llogan> if i did i don't remember
[21:56] <ericgudmundson> okay thank you
[21:57] <llogan> a git bisect would be useful to determine if it is a regression, but that may be time consuming if it takes 6 hours per test
[21:59] <ericgudmundson> okay I will give it a try. Thank you for your help
[22:01] <llogan> but enough information for others to reproduce would be useful too
[22:01] <llogan> regressions are considered important (but i have no idea if this is a regression)
[22:05] <batbat_> hello, anybody there?
[22:05] <llogan> yes
[22:05] <llogan> there is always someone here
[22:06] <ericgudmundson>  K thank you
[22:06] <batbat_> hi fake od man, I can't get re-enrolled to the mailing list, maybe my hotmail addy is blocked
[22:07] <llogan> hotmail has been acting badly lately
[22:07] <batbat_> @ fake, what shall I do
[22:07] <llogan> they are possibly assuming that the ffmpeg mail server is "bad"
[22:07] <llogan> you can contact hotmail about it. not much i can do as far as i know
[22:08] <llogan> you can try a more sane email service
[22:08] <batbat_> yes, hotmail is not so good
[22:09] <llogan> tell them to take ffmpeg.org off of their "421 RP-001"
[22:10] <ericgudmundson> llogan, I have found the command that we used to test with : ffmpeg -i udp://232.X.X.X:PORT?sources=172.31.2.22 -vcodec yuv4 -acodec pcm_s16le -f mpegts -y /dev/null
[22:10] <ericgudmundson> The input audio is AC3 if that is any help
[22:10] <llogan> does it do the same with a local version of the same file?
[22:10] <batbat_> "421 RP-001" I don't know what that is, but maybe I will send an email to hotmail at hotmail, lol
[22:11] <llogan> http://mail.live.com/mail/troubleshooting.aspx#errors
[22:11] <ericgudmundson> We don't have a local copy of the same file.
[22:12] <ericgudmundson> But That would be one way that we could test the problem'
[22:13] <batbat_> "421 RP-001" OK
[22:18] <batbat_> Have sent message to "something is broken" at outlook
[22:19] <llogan> thanks, but did you not see my private chat to you?
[22:19] <batbat_> outlook:- Thank you for taking the time to send us your thoughts.  We do use your comments to improve Outlook.
[22:41] <batbat_> llogan, you still here?
[22:43] <batbat_> hullo
