[01:35] <durandal_1707> michaelni: xpm decoder needs adding more colors to color table in lavu/parseutils
[01:43] <michaelni> adding more should not be a problem
[02:48] <Nickname123> The other day I opened a feature request: https://ffmpeg.org/trac/ffmpeg/ticket/1483
[02:49] <Nickname123> I toyed around with implementing it: https://github.com/thenewguy/FFmpeg/commit/c92a070d376cff11af6011911325893847f240bb
[02:49] <Nickname123> Are github pull requests an acceptable way to submit a patch?
[02:50] <durandal_1707> i don't think so
[02:51] <Nickname123> I have read http://git.videolan.org/?p=ffmpeg.git;a=blob_plain;f=doc/issue_tracker.txt;hb=HEAD
[02:51] <durandal_1707> Nickname123: http://ffmpeg.org/developer.html#Contributing
[02:52] <Nickname123> How do I go about getting my patch approved by another person
[02:52] <Nickname123> okay Ill read that one
[02:52] <Nickname123> Oh nice.  Github is accepted =)
[02:53] <durandal_1707> pull request may be ignored, patches to ml list less so
[02:53] <Nickname123> Okay.  I didn't see a guide to creating patches.  Should they be from the base FFmpeg repo?

[02:55] <Nickname123> well dang. my bad
[03:02] <Nickname123> thanks durandal_1707 btw
[03:09] <Nickname123> Is it possible to sign off on a commit after it has been committed?
[03:27] <durandal_1707> michaelni: already available colors in parseutils conflict with xpm/x11 definitions, like green color it is more for SVG compliance
[04:36] Action: Nickname123[A] is now away - Reason : sleep
[07:36] <ubitux> Nickname123[A]: please follow the surrounding coding style, use av_strtok() instead of strtok(), use strtol() instead of atoi()
[07:36] <ubitux> Nickname123[A]: also, since you're working on the segmenter, you should see with Stefano (saste) when he is here
[07:36] <ubitux> he's done some work on it
[07:36] <ubitux> (which he hadn't submitted yet...)
[07:37] <ubitux> see https://gitorious.org/~saste/ffmpeg/sastes-ffmpeg/commits/misc-segment-fixes-20120206 for instance
[07:37] <ohsix> is av_strtok like strtok_r

[08:22] <jesk> good morning
[08:24] <jesk> before me opens bug maybe it would make sense to get confirmation here in the first place
[08:24] <jesk> i'am too unexperienced if that could be expected behavior
[08:25] <jesk> i have pretty simple configuration, more or less stripped down the example configs to only have one stream and one feed
[08:25] <jesk> when adding the multicast options to the stream configuration the server won't response anymore to http request
[08:26] <jesk> s,to http request, to any http request,
[08:26] <jesk> i'am using 0.11.1, osx build
[08:27] <jesk> when removing the multicast options the server responses again
[08:29] <jesk> i tried the debug flag, but tells nothing about this
[10:08] <michaelni> jesk, for which protocol do you need multicast and for what do you need http

[11:20] <mwkenna> Hi guys. I have a question with regards to FFMpeg and LibAv. What's the difference? Also - does the old FFMPEG API mailing list still run?
[11:21] <mwkenna> (I am using avcodec for my projects also)

[13:08] <DEgITx> hellow guys, may i ask some questions about ffmpeg api?
[13:10] <michaelni> yes
[13:13] <michaelni> j-b, about the vscprintf issue, can you provide more details about the build environment (to nicolas) ?
[13:14] <DEgITx> first one about av_read_frame()... is there any posible way to know return maximum packet size?
[13:14] <michaelni> both mingw 32 & 64bit fate.ffmpeg clients are also green 
[13:16] <michaelni> DEgITx, the maximum is limited by the file format, by INT_MAX of the size field and in some cases by the maximunm packet size of the codec
[13:16] <michaelni> its also limited by max_alloc_size indirectly
[13:18] <michaelni> it also is limited by the filesize in many cases
[13:26] <DEgITx> ok ... MAX_INT bad choise for limitation in my way), so is any posible simple ways to get codec/file limit (independently from codec and file format) ?
[13:27] <michaelni> theres no lisit in ffmpeg about such limits no, btw why do you need to know it ?
[13:27] <DEgITx> i mean AVCodecContext or something like this
[13:30] <DEgITx> i'm trying to play file while it's downloading (such task), and care about av_read_frame() to have enough bytes for reading
[13:32] <michaelni> you would have to add support to the demuxer to return EAGAIN in if theres not enough data
[13:32] <michaelni> that is if you want it to work well
[13:32] <michaelni> with low latency
[13:33] <michaelni> max frame/packet size can be quite large compared to average with many file formats
[13:34] <DEgITx> about reading again, what do you mean (any example?)
[13:36] <michaelni> that a demuxer and  av_read_frame would return EAGAIN if there is not enough data instead of blocking or retunrning EOF
[13:36] <michaelni> and that they then could continue/be retried when theres more data
[13:36] <michaelni> but as said you would need to add support for this in libavformat to the demxuer that you need
[13:42] <DEgITx> and there is no problem with truncation of packets in such way?
[13:44] <michaelni> no, the demuxer would have to seek back and restore any changes to its state before retunring EAGAIN
[13:55] <DEgITx> ok, i understand that it's good variant to add support direct to the demuxer... but i'm trying don't touch sources of ffmpeg and making realization separately from it as well as caring about integrity of file
[14:44] <j-b> michaelni: normal debian, i586-migw32msvc from mingw.org
[14:47] <michaelni> j-b, thx, i forwarded the awnser to nicolas
[15:01] <funman> mingw.org disappeared from sid btw
[16:52] <nevcairiel> people are still using old legacy-mingw?
[16:57] <j-b> yes.
[16:59] <nevcairiel> they should stop :P
[17:03] <j-b> when ming-w64 will be stable, indeed
[17:06] <funman> if you have an issue with mingw-w64 just tell me
