[00:59] <cone-292> ffmpeg.git 03Michael Niedermayer 07master:6db57fa8bc1a: avcodec/mjpegdec: Support RGBA lpegs
[01:00] <durandal_1707> what is lpegs ?
[01:08] <Compn> ljpegs
[01:09] <durandal_1707> no its not, its typo
[01:11] <durandal_1707> michaelni: what is J thing commented out?
[01:13] <durandal_1707> also if i do conversion with scale filter from non YUVJ to YUVJ will it do right conversion now (without any additional options)?
[01:17] <durandal_1707> color_range is not used by scale filter, but ideally it should be used with 'auto' ....
[01:21] <michaelni> YUVJ->YUVJ should work
[01:21] <durandal_1707> not YUVJ aka YUV -> YUVJ
[01:21] <michaelni> that should work too
[01:36] <durandal_1707> michaelni: i think subsampled yuv should not be hard to add to j2kdec
[01:40] <durandal_1707> BuxiNess: does jpeg2000 performance matches libopenjpeg or its still worse?
[01:41] <j-b> matches, IIRC
[02:09] <axorb> hey guys, I'm modifying the mp3 encoder to include a guess of the total number of frames
[02:09] <axorb> how would I go about getting the input duration?
[02:10] <axorb> I'
[02:10] <axorb> I'm dealing with streams here so it can't be 100% accurate, I just want to provide the user with something rather than default to 0
[02:15] <michaelni> axorb, see AVDurationEstimationMethod
[02:15] <axorb> neat, thanks
[02:25] <axorb> actually, I don't understand how the encoder and decoder interact 
[02:26] <axorb> I've got an AVFormatContext, but the duration is not set because it isn't used when encoding
[02:26] <axorb> somebody I need to get the length from the decoder but I'm looking for examples but not finding anything yet
[02:27] <axorb> somehow* and*
[02:53] <axorb> yeah, all of the AVFormatContext is empty and there isn't enough in AVCodecContext
[02:54] <axorb> I'm just trying to make it automatic, but I guess I can just have the user pass in the duration
[02:55] <axorb> I don't understand the workflow enough at the moment to do it properly
[03:01] <cone-292> ffmpeg.git 03Michael Niedermayer 07master:a7e45cfa1185: swscale/sws_getColorspaceDetails: dont fail for non yuv
[03:01] <cone-292> ffmpeg.git 03Michael Niedermayer 07master:5156d482cd60: avfilter/vf_scale: use the inputs color range when its set and its not overridden
[09:20] <BuxiNess> durandal_1707, j-b, Now jpeg2000 quicker
[09:20] <BuxiNess> But not all pathces for speed up pushed yet
[09:20] <BuxiNess> mainly SSE stuff
[10:22] <cone-532> ffmpeg.git 03Martin Storsjö 07master:54ba52077c96: arm: Comment out unused labels in simple_idct_arm
[10:23] <cone-532> ffmpeg.git 03Michael Niedermayer 07master:0815b230628e: Merge remote-tracking branch 'qatar/master'
[16:19] <durandal_1707> michaelni: recent filter change introduced bunch of errors in valgring full fate box: http://fate.ffmpeg.org/report.cgi?time=20130725053855&slot=x86_64-archlinux-gcc-valgrindundef
[16:26] <wm4> saste: how do I handle EOF correctly with libavfilter? just calling av_buffersink_get_frame() until no frame is returned doesn't seem to work
[16:33] <durandal_1707> saste: will program thing for ffprobe be finally committed?
[16:38] <xlinkz0> can ffmpeg be built using something other than gcc?
[16:38] <durandal_1707> xlinkz0: yes
[16:39] <xlinkz0> clang?
[16:39] <Plorkyeran> clang, icc, msvc (with the help of c99conv)
[16:39] <Plorkyeran> maybe the dumb sun compiler?
[16:40] <cptspiff> that would surprise me ;)
[16:42] <xlinkz0> damn apple llvm-gcc is old as shit doesn't support thread local
[16:42] <nevcairiel> I think suncc even works
[16:43] <nevcairiel> http://fate.ffmpeg.org/history.cgi?slot=x86-opensolaris-suncc5.10 found a fate box with it :D
[17:15] <cone-532> ffmpeg.git 03Michael Niedermayer 07master:6bde1e9d14ff: avfilter/avfiltergraph: fix check using the wrong variables
[17:15] <cone-532> ffmpeg.git 03Michael Niedermayer 07master:de0a1f63dff9: avfilter/can_merge_formats: fix memleak
[17:21] <ramiro> saste: hi!
[17:22] <ramiro> where's the best place to document that change I sent for img2enc?
[17:22] <durandal_1707> doc/muxers.texi
[18:17] <aballier> avformat_query_codec for ticket 2209 ?
[18:51] <durandal_1707> cehoyos best of the best ^
[19:50] <llogan> durandal_1707: where did you find that sample (ticket 2810)?
[20:02] <durandal_1707> llogan: iirc superuser  something
[20:02] <durandal_1707> by using google
[20:02] <durandal_1707> searching for something unrelated....
[20:07] <durandal_1707> http://stackoverflow.com/questions/17809407/ffmpeg-cannot-open-a-simple-microsoft-wav-file-exported-with-audacity
[20:07] <durandal_1707> i did not checked is this because of file size or something else ...
[21:57] <durandal_1707> stop the spam
[22:14] <cone-400> ffmpeg.git 03Reuben Martin 07master:4a60df2d35e7: avformat/gxfenc: Added support for writing correct auxiliary data for DV streams.
[22:23] <durandal_1707> do not use past tense in log messages
[22:42] <cone-400> ffmpeg.git 03Paul B Mahol 07master:fd84b6fd3389: lavu/opt: show default values for AV_OPT_TYPE_PIXEL_FMT and AV_OPT_TYPE_SAMPLE_FMT too
[23:16] <durandal_1707> beastd: no more logo contest?
[23:16] <beastd> hi
[23:16] <llogan> durandal_1707: you complained about it too much
[23:17] <durandal_1707> ahh, you mean that airplane thing :)....
[23:17] <cone-400> ffmpeg.git 03Carl Eugen Hoyos 07master:8ca3766f007d: Allow native compilation on the iPhone.
[23:17] <beastd> it was a bit unfortunate this time. but i plan to restart in autumn
[23:17] <cone-400> ffmpeg.git 03Carl Eugen Hoyos 07master:9375879d5702: Show max bitrate for mpeg2 video streams in avcodec_string().
[23:17] <cone-400> ffmpeg.git 03Michael Niedermayer 07master:1af921196fbc: Merge remote-tracking branch 'cehoyos/master'
[23:19] <llogan> if we resume i'd like to see more submissions per contest, but i'm unsure of the best way to do that.
[23:21] <beastd> durandal_1707: i was also thinking about your request about different sizes. and you mentioned you would also consider a new different logo. i don't want to have submissions that use a logo that will be changed.
[23:22] <beastd> OTOH: if we would really decide to vote for a new logo the contest/search should be opened for month anyway. so i think autumn banner contest can be done anyway with the current logo.
[23:22] <durandal_1707> well idea about new logo is just that, if others prefer curren 3d one.... i not going to insist
[23:23] <beastd> agreed. a single person shouldn't decide about that anyway.
[23:26] <beastd> we also should bring up logo licensing once again. i think e.g. one of the CC licenses should actually be suitable. i would like to present all logos on a wiki page so visitors can look at them and download them under a clear legal conditions (as clear as legal gets that is).
[23:30] <beastd> maybe by-nc-sa 3.0
[23:33] <llogan> the 3d logo is troublesome for some printing
[23:33] <beastd> ack
[23:38] <llogan> also usage of a free font should be a requirement if there is a new logo. it's restrictive to only be able to work with text outlines because herve never said what typeface he used and he never responded to my questions.
[23:38] <durandal_1707> i looked at photo of those stickers and they are ugly
[23:38] <llogan> what's ugly about them?
[23:38] <durandal_1707> or maybe it was low resolution....
[23:39] <llogan> i already mentioned in the RFC stickers that the printing quality could have been better if that is what you are referring to.
[23:41] <llogan> beastd: you should have michaelni send you some stickers since you attend the conventions (thilo sent him too many)
[23:41] <beastd> ok
