[01:00:49 CEST] <cone-147> ffmpeg 03Michael Niedermayer 07master:697b2bbd54d0: avcodec/ffv1dec: Test extradata_size instead of extradata for better robustness
[01:14:55 CEST] <cone-147> ffmpeg 03Michael Niedermayer 07master:b9d77c1dfc28: doc/protocols: Fix seperated typo
[01:15:07 CEST] <ubitux> http://ubitux.fr/pub/pics/ffcurvesdbg.png do ppl usually prefer a normalized legend [0;1] or sth like this?
[01:19:05 CEST] <ubitux> so vs this: http://ubitux.fr/pub/pics/ffcurvesdbg-normalized.png
[01:19:13 CEST] <ubitux> also, i could change the ticks
[01:19:37 CEST] <ubitux> (context: adding an option to curves filter to debug them out)
[01:21:40 CEST] <ubitux> http://ubitux.fr/pub/pics/ffcurvesdbg-normalized-01tics.png i like this one ...
[02:35:29 CEST] <ubitux> can't delete files in trac? i messed up a bit
[03:04:32 CEST] <jamrial> ubitux: someone with enough privileges probably can
[03:17:13 CEST] <cone-147> ffmpeg 03Yong Lei 07master:8dcfe43de09b: avcodec/huffman: beautify: add space between #include and filename.

[09:51:37 CEST] <midnight> Hi.Is anyone there?
[09:53:51 CEST] <midnight> I read the source of the function av_image_get_linesize in imgutils.h.Its param plane confused me .
[09:55:55 CEST] <andrey_turkin> what exactly confused you?
[09:56:00 CEST] <midnight> it is unused,I wonder why it added ?Thanks.
[09:56:19 CEST] <andrey_turkin> it is not unused in sources I have
[09:56:27 CEST] <andrey_turkin> it cannot be unused in fact
[09:56:58 CEST] <andrey_turkin> because linesize depends on a plane. E.g. for yuv420p chroma planes have smaller linesizes than luma plane
[09:57:54 CEST] <midnight> when i wanted to get linesize, what param should I supply?
[09:58:07 CEST] <andrey_turkin> well, plane number
[10:00:22 CEST] <midnight> where can I find the number corresponding to some specific images?
[10:02:28 CEST] <andrey_turkin> maybe you have some misconception about what this function does. Anyway, it seems like this discussion belong at #ffmpeg channel instead
[10:06:18 CEST] <midnight> In fact, when I call this function av_image_fill_arrays in imgutils.h,  I found that I have no idea about param dst_linesizes[4],
[10:06:56 CEST] <midnight> And I think I can get inesizes by this funciton av_image_get_linesize.
[10:09:22 CEST] <midnight> But i found soon I don't know the param plane either.
[10:23:09 CEST] <andrey_turkin> do you know what planes are?
[10:24:51 CEST] <Betablocker> hihi
[12:57:15 CEST] <jermy> Probably more a mailing list question, but we've got a client wanting us to embed 608/708 captions in quicktime files - it can be done as a separate track with ccdp packets separate from the video, so somewhat easier than the AVC SEI NAL embedding option (or similar for MPEG2)
[12:58:04 CEST] <jermy> Is there any formal process for ffmpeg bounties, or more a case of finding somebody who is interested?
[13:06:46 CEST] <cone-224> ffmpeg 03Michael Niedermayer 07master:e83a01def3ad: avformat/teeproto: Fix memset sizeof
[13:46:36 CEST] <omerjerk> hi Michael told me to replace this code - https://github.com/omerjerk/FFmpeg/blob/float_patch/libavcodec/alsdec.c#L1505
[13:46:40 CEST] <omerjerk> with av_rb32
[13:46:55 CEST] <omerjerk> I'm not getting which function to use exactly. 
[13:47:05 CEST] <omerjerk> it's present in several header files
[13:47:55 CEST] <Chloe> jermy: probably just send it to the mailing list.
[13:48:51 CEST] <michaelni> omerjerk, its a macro
[13:49:14 CEST] <omerjerk> yes. but I'll need to include some header file I guess.
[13:49:24 CEST] <michaelni> omerjerk,  libavutil/intreadwrite.h
[13:49:46 CEST] <michaelni> AV_RB32 not av_rb32
[13:49:52 CEST] <omerjerk> okay. I was confused because there's one in bytestream.h too I guess
[13:49:57 CEST] <omerjerk> ohkay
[14:45:57 CEST] <cone-224> ffmpeg 03Petru Rares Sincraian 07master:fa393e30614b: fate: add test for extrastereo filter
[15:43:34 CEST] <tmatth> kierank: do you have a list of the samples you ran through fffuzz?
[16:08:54 CEST] <kierank> tmatth: nop
[16:08:59 CEST] <kierank> just random samples I made
[16:10:31 CEST] <tmatth> i guess more importantly, roughly what codecs you tested?
[16:11:12 CEST] <kierank> h264, mpeg2, opus, ffv1
[16:11:43 CEST] <kierank> but this was before all the stupid merges in ffmpeg
[16:11:47 CEST] <kierank> and rearrangements in libav
[16:37:30 CEST] <cone-224> ffmpeg 03Steven Liu 07master:6f0746783124: doc/muxers: add hls_flags option description
[16:37:31 CEST] <cone-224> ffmpeg 03Steven Liu 07master:41ad6d193ade: doc/muxers: improve hlsenc description
[17:03:34 CEST] <cone-224> ffmpeg 03Sasi Inguva 07master:282477bf4534: libx264: Increase x264 opts character limit to 4096
[17:04:36 CEST] <JEEB> we should really normalize for x264-params...
[17:05:23 CEST] <JEEB> x264opts maps things locally while x264-params just sends k/v pairs to libx264
[18:58:44 CEST] <cone-182> ffmpeg 03Jan Sebechlebsky 07master:8c997b3d3d1b: avcodec/mpeg4_unpack_bframes_bsf: Copy packet props
[19:14:15 CEST] <cone-182> ffmpeg 03Jan Sebechlebsky 07master:1c46e53dcc68: avcodec/mpeg4_unpack_bframes_bsf: Check av_packet_from_data() return value
[19:23:59 CEST] <cone-182> ffmpeg 03Carl Eugen Hoyos 07master:db8e8c97311a: lavc/intrax8: Use correct printf specifier for size_t on Windows.
[21:25:36 CEST] <Chloe> Who maintains files which have no explicit maintainer?
[21:29:17 CEST] <iive> Chloe: michaelni 
[22:01:15 CEST] <jamrial_> Chloe: nobody in particular, hence no explicit maintainer, but if you find a bug report it on trac, and someone that knows the code may look at it
[23:59:30 CEST] <kode54> dammit
[23:59:38 CEST] <kode54> oh, I found it
[23:59:51 CEST] <kode54> I have a modified version of the mp3 stream parser that handles iTunes gapless info
