[00:56] <BBB> Compn: I assure you I dont have mplayer installed; Id be surprised if I used it in the last 10 years
[00:57] <BBB> Compn: so no, not all devs use mplayer as their primary testing tool
[00:57] <BBB> if mplayer was user-friendly&
[01:00] <wm4> not even I have mplayer installed
[01:00] <wm4> too hard to build
[01:32] <Daemon404> 23
[01:49] <cone-974> ffmpeg.git 03Michael Niedermayer 07master:2db1bcf1b982: avformat/asfdec: Try to improve skip case
[09:56] <ubitux> Timothy_Gu: btw, you do some advertising to Libav features in the release notes; i think you should either credit the project, or remove them from the changelog
[09:57] <ubitux> it's not very honest from us to advertise such features
[10:51] <cone-816> ffmpeg.git 03Muhammad Faiz 07master:860d12978c3a: doc/filters: fixing typo
[11:47] <cone-816> ffmpeg.git 03Timothy Gu 07master:2a9b4c0f05c2: Add a release note for 2.3
[12:00] <michaelni> ubitux, just saw your comment now, but should we credit each author for each feature in the release notes ?
[12:01] <ubitux> not each author, it's just that libav definitely didn't do these contributions for ffmpeg, in comparison to other features
[12:04] <michaelni> libav is not a person, its the authors who did the work
[12:05] <michaelni> also neither project listed a "from project" in the previous changelog
[12:05] <michaelni> iam not against it in principle its just very strange
[12:09] <michaelni> also i resign from maintaining this just in case its unclear
[12:10] <michaelni> i certainly cannot on every merge keep such extra credits up to date when the original authors dont write such credits
[12:13] <ubitux> note that i wasn't talking about the list of changes themselves, but more the highlights at the beginning
[12:20] <J_Darnley> Regarding that release note, shouldn't this "libavutil      xx.yy.1zz" list an actual version?
[12:21] <michaelni> yes the versions should be fixed, i mainly pushed it to simplify collaboration, i did expect it to take a few more edits before the release
[12:21] <J_Darnley> Oh, that's because 2.3 hasn't been made yet
[12:21] <J_Darnley> My bad.
[12:32] <michaelni> ubitux, if you want to add some libav references, i guess send a patch that adds them or that removes the parts. But still it feels very strange to me to credit the project instead of the authors
[12:35] <michaelni> also for example assuming you talk about opus which says "Copyright (c) 2012 Andrew D'Addesio and Copyright (c) 2013-2014 Mozilla Corporation and  @author Andrew D'Addesio, Anton Khirnov" , iam not sure that crediting this as a "from libav" is the proper thing to do
[12:36] <michaelni> i dont know which part and how much is from whom but "Mozilla Corporation" certainly isnt part of libav
[13:16] <michaelni> ubitux, proper credit for opus might be something like "Initial implementation by Andrew D'Addesio <modchipv12 at gmail.com> during  GSoC 2012. Completion by Anton Khirnov <anton at khirnov.net>, sponsored by the Mozilla Corporation, additional contributions by several other developers, the code was merged from Libav into FFmpeg" but this feels a bit long for the release notes. i guess ill leave it to you and others to decide wha
[13:16] <michaelni> t is the best thing to do about it
[14:15] <Compn> 'author copyrights can be found in the source code' ? :)
[14:15] <Compn> ehe
[14:15] Action: Compn afk
[15:08] <cone-773> ffmpeg.git 03Michael Niedermayer 07master:47c84c0bf784: avformat/wavdec: add basic sanity check for the sample count
[16:39] <j-b> 'morning
[17:15] <michaelni> afternoon
[17:22] <cone-773> ffmpeg.git 03Michael Niedermayer 07master:ec24796731d3: RELEASE_NOTES: fill in lib versions
[17:22] <cone-773> ffmpeg.git 03Michael Niedermayer 07master:68215724997c: avformat/movenc: dont mark multichannel as mono tracks as containing the center channel
[19:00] <michaelni> ubitux, Timothy_Gu (and others), what do you prefer we do about the release_notes author/project credit ? is it ok as it is? should i add the proper full credit as a footnote or something or remove opus or something else ?
[19:26] <a141982112>  dvbsubdec to overlay fails to produce correct output
[19:28] <a141982112> this is might be because of compute_edt set to 1 automatically in ffmpeg 
[19:30] <a141982112> I wanted to change this behaviour to only when dvbsub is transcoded not overlayed
[19:30] <a141982112> is checking filters option in ffmpeg.c is good idea
[20:16] <michaelni> a141982112, sounds like a hack
[20:18] <a141982112> i need to check that dvbsub subtite stream are mapped to one subtitle stream 
[20:18] <a141982112> is there any better way
[20:41] <a141982112> just now i am using [0:v][0:s]overlay[v] filter to test, is it possible/reasonable when we use filter for subtitle and in outstream we get subtitle stream
[21:04] <a141982112> I have sended the hack patch, because code for checking mapped stream was becoming big 
[21:33] <Timothy_Gu> michaelni, ubitux: how about "This ffmpeg release (also) contains new features from Libav like Opus ..."
[21:36] <ubitux> Timothy_Gu: sounds good to me

[22:20] <jamrial> Timothy_Gu: for that matter, maybe rewording "We have already ported some 32-bit ARM to AArch64" into "some 32-bit ARM has already been ported to AArch64", since "we" didn't port it.
[22:29] <Timothy_Gu> michaelni: do you want to release a beta for 2.3?
[22:31] <michaelni> no
[22:32] <michaelni> but i need to release a new 2.2, as it has a ABI bug
[22:33] <Timothy_Gu> What is your intended codename?
