[03:48] <cone-167> ffmpeg.git 03Lukasz Marek 07master:4a0b1d924564: lavc/libxvid: workaround for bug in libxvidcore
[05:16] <cone-167> ffmpeg.git 03Michael Niedermayer 07master:a7ebd0b011f9: avcodec/mpegaudiodec_template: only allocate fdsp when its used
[07:09] <Timothy_Gu> Tired of Libav cherry picking patches with and/or without proper attribution.
[07:12] <rcombs> what's wrong if they do attribute properly?
[08:21] <Timothy_Gu> rcombs: flood of patches that are déjà vu in FFmpeg-devel, some of them fixing bugs created by patches that passed their own review procedures and caught by Michael during merges.
[08:23] <rcombs> Timothy_Gu: well we (and by we I mean Michael) merge from them too :\
[10:47] <ubitux> mmh the mvs in h264 are subpixels?
[10:55] <ubitux> so like 1/4 or 1/16
[10:57] <ubitux> i see there is a shift in the values by 1 or 2 (1 + quarter_pixel)
[11:35] <michaelni> ubitux, yes mvs are in subpixels units in most MC+residual coding codecs
[11:36] <ubitux> mmh
[11:36] <ubitux> ok
[13:06] <koda> rcombs: dunno what he was about but probably he probably thinks its bad to help one of the main sources of ffmpeg codebase ;)
[13:07] <koda> rcombs: also complaining in the wrong channel, that will surely help -.-
[13:32] <funman> kierank: http://pastie.org/9762489
[13:33] <kierank> Hmmmm
[13:33] <funman> weird thing is
[13:33] <funman> the parser is run 2 times: at demuxing and then decoding
[13:33] <funman> and the demuxing part looks fine
[13:33] <funman> s/looks/is
[13:34] <funman> there are no errors before decoding starts
[13:35] <funman> http://pastie.org/9762499
[13:39] <kierank> Would need to also talk with elenril
[13:39] <funman> so it works from avformat_find_stream_info but not from av_read_frame
[13:43] <funman> hm I wonder if the opus frame was not consumed entirely
[13:45] <funman> http://pastie.org/9762507
[13:47] <nevcairiel> something odd is happening there
[13:48] <funman> http://chui-pas.net/~fun/test-8-7.1.opus.ts  md5 2441470d04203c9fbf50a6d3d7f6f038
[13:50] <nevcairiel> heh, the libopus decoder doesnt work on that at all, even during opening it already fails
[13:50] <funman> during opening?
[13:50] <nevcairiel> [mpegts @ 007c9800] Could not find codec parameters for stream 0 (Audio: opus (Opus / 0x7375704F), 48000 Hz, 49 channels (FR+BR+FRC+BC+SR+TC+TFL+TFC+TFR+TBL+TBC+TBR+DL+LFE2), s16): unspecified number of channels
[13:50] <nevcairiel> something funny is going on :p
[13:51] <funman> ;)
[13:51] <funman> maybe the channel map is not transmitted
[13:51] <koda> its the 22.2 new channel mapping ;)
[13:51] <nevcairiel> with 49 channels? :D
[13:59] <funman> ts_framing is always set
[14:05] <kierank> funman: i think not all the channel maps are implemented in ffmpeg
[14:05] <koda> Timothy_Gu: as you saw there was no wrong attribution, actually a proper case of bugzilla stalking was discovered so thanks for your comment
[14:05] <funman> ah subpackets are parsed at their turn
[14:05] <koda> Timothy_Gu: also i believe you are complaining about something not related to this channel
[14:06] <funman> but the last subpacket doesn't have a size
[14:08] <funman> and self_delimiting is set
[14:08] <funman> and "value has been optimized out" :(
[14:13] <funman> http://pastie.org/9762541
[14:13] <funman> that fixes .ts playback but breaks the .opus version
[14:15] <funman> I guess nb_streams is wrong
[14:18] <funman> kierank: I can't see where the opus_audio_descriptor is parsed
[14:19] <kierank> In the demux
[14:20] <funman> right
[14:23] <funman> kierank: http://pastie.org/9762556
[14:29] <funman> same issue than with VLC, I don't hear the 8th channel.. (the cow says kaboom)
[14:34] <funman> https://ffmpeg.org/pipermail/ffmpeg-devel/2014-December/166391.html
[14:59] <kierank> funman: thanks
[15:00] <funman> at your service
[16:01] <cone-644> ffmpeg.git 03Rafaël Carré 07master:57bfafe76be5: avformat/mpegts: fix Opus stream count
[17:36] <cone-644> ffmpeg.git 03Piotr Fusik 07master:c99e5191ab84: doc/examples/filtering_video: fix frame rate
[17:45] <kierank> funman: does that patch fix opus decoding for all?
[17:46] <funman> all?
[17:46] <kierank> for all channel maps
[17:46] <kierank> I mean
[17:47] <funman> yes should work afaiu
[17:48] <funman> but, test-8-7.1.opus lfe channel doesn't play
[17:48] <funman> it's not related to ts though
[17:49] <kierank> report bug to elenril i guess
[17:50] <nevcairiel> i wonder if libopus would work now with the fix
[18:20] <tonyd> anyone who knows a freelance consultant for ffmpeg?
[18:20] <tonyd> please advice
[18:21] <tmatth> tonyd: http://ffmpeg.org/consulting.html
[19:03] <Daemon404> j-b, is schannel allowed on WinRT?
[19:05] <j-b> Daemon404: I think so, at least partly
[19:05] <j-b> CoInitializeSecurity works for example
[19:05] <Daemon404> oic
[19:05] <Daemon404> i was toyign with schannel in tls.c
[19:05] <Daemon404> (fuck that api btw)
[19:06] <j-b> yep
[19:09] <j-b> Daemon404: but maybe only through StreamSocket
[19:09] <Daemon404> :V
[19:09] <j-b> How do you need it?
[19:10] <Daemon404> i was just toying with it
[19:10] <Daemon404> for https support with no deps
[19:10] <j-b> http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.sockets.streamsocket.upgradetosslasync
[19:27] <nevcairiel> i've always had that on my long-term todo to implement it, but i never found the time :d
