[10:45:26 CEST] <cone-669> ffmpeg 03Paul B Mahol 07master:d492907e7817: avfilter/af_amix: fix filtering if specified weights are negative
[11:24:50 CEST] <cone-669> ffmpeg 03Paul B Mahol 07master:8ca89e52df89: avfilter/f_streamselect: fix memleaks of pad names
[12:04:16 CEST] <durandal_1707> when to use av_cold ?
[12:06:55 CEST] <J_Darnley> durandal_1707: probably when the function will be called once at start or at end.
[12:07:26 CEST] <J_Darnley> I wonder if there's an commnent about ti somewhere
[12:09:23 CEST] <J_Darnley> "Did you use av_cold for codec initialization and close functions?" in doc/developer.texi
[12:10:57 CEST] <J_Darnley> all I could find though
[12:11:37 CEST] <cone-669> ffmpeg 03Paul B Mahol 07master:22f3b6286eaa: avfilter: add av_cold where it is missing
[13:49:00 CEST] <kierank> durandal_1707: I think largely voodoo
[13:53:14 CEST] <durandal_1707> kierank: av_cold is not voodoo
[13:53:23 CEST] <kierank> almost certainly is
[14:24:10 CEST] <cone-669> ffmpeg 03Paul B Mahol 07master:d0189f8d976f: avfilter/vsrc_sierpinski: add triangle type
[15:07:13 CEST] <psycho_9> re
[15:07:27 CEST] <psycho_9> is messaging on #ffmpeg blocked for some reason?
[15:13:01 CEST] <thardin> could be freenode requiring registration again, due to spam
[15:13:25 CEST] <psycho_9> oh, right... forgot about nick registration ;)
[16:50:32 CEST] <atbd> hi, i'm currently working on DVB streams and adding data table (NIT, EPG for now) to ffmpeg. For now support is barebone: a data packet is formed and that's all. But I'd like to add decoding support for those data tables, does ffmpeg wants data decoder for them or do I make this out of ffmpeg ?
[16:57:50 CEST] <J_Darnley> What ffmpeg structure could you decode them into?  AVDictionary?
[17:01:06 CEST] <atbd> I made structures describing tables/subtables/descriptors and store them in AVFrame::side_data for my tests
[17:07:10 CEST] <atbd> I store only a pointer to the table which contains the others smaller struct
[17:15:39 CEST] <kierank> I don't see how this can fit into ffmpeg at all
[17:15:48 CEST] <kierank> they have nothing to do with AVFrame
[17:22:01 CEST] <atbd> Can I expose those struct and public functions to parse those data packets through ffmpeg API ?
[17:23:07 CEST] <kierank> imo defeats the point of ffmpeg to have MPEG-TS specific structures
[17:23:13 CEST] <kierank> should use an mpegts demux library
[17:23:31 CEST] <kierank> you could maybe have a demuxer callback api
[17:23:36 CEST] <kierank> for metadata that isn't associated with a packet
[17:23:40 CEST] <kierank> that could be used generically imo
[17:40:47 CEST] <atbd> okay, thanks for the answer
[17:41:02 CEST] <atbd> i'll try that
[17:56:02 CEST] <mkver> cehoyos: Remember that flac ticket you wanted to open? Well, you don't need to. Both the serious as well as the bogus warnin message have the same cause.
[17:56:41 CEST] <durandal_1707> mkver: which cause?
[17:58:35 CEST] <mkver> An off-by-one error in find_new_headers: Instead of read_len = search_end - search_start + 1 it should be read_len = search_end - (search_start + 1) + 1;
[17:58:54 CEST] <mkver> But only after wraparound.
[17:59:23 CEST] <durandal_1707> patch welcome
[17:59:54 CEST] <mkver> Yeah, I know and intend to do so.
[18:01:08 CEST] <cone-711> ffmpeg 03Paul B Mahol 07master:93ea21f9b7cc: doc/filters: fix typo
[18:09:11 CEST] <cehoyos> mkver: Thank you for the analysis!
[19:17:46 CEST] <kierank> durandal_1707: wtf
[19:17:48 CEST] <kierank> that bug report
[21:34:50 CEST] <cone-437> ffmpeg 03Andreas Rheinhardt 07master:c548b0a4c67b: avformat/aiffenc: Use standard packet list functions
