[00:17] <CIA-41> ffmpeg: yadif: redesign first and last 2 lines handling.
[00:17] <CIA-41> ffmpeg: The previous code dependent on the input buffer matching the
[00:17] <CIA-41> ffmpeg: buffer that has been provided by yadifs get_buffer.
[00:17] <CIA-41> ffmpeg: The API does in now way gurantee this though its often true.

[00:17] <CIA-41> ffmpeg: yadif needs at least 3x3 or it will likely crash with out of array reads

[00:18] <michaelni> kierank, yadif should be fixed, if you still have crashes please ping me
[00:18] <kierank> michaelni: thank you
[00:56] <Mista_D> Possible to ensure ffprobe values are in the same sequesnce when outputing to CSV ?? Extracting video PID with `ffprobe...-show_streams -print_format csv|grep video|cut -d, -f19`. Sometimes PID is -f16 on MPEG2-TS files.

[13:31] <Compn> The vlc ticket was a duplicate of FFmpeg ticket #780 (at least concerning 
[13:31] <Compn> the patch fixing it). The crash was fixed within 24 hours by Michael in 
[13:31] <Compn> December, it is fixed in all release branches since 0.5.

[13:32] <Compn> vlc ticket 6000 that is
[13:32] <Compn> hi carl reading this later on the mailing list ;)
[14:06] <ubitux> wtf haiku
[14:07] <ubitux> perl in /boot/common/bin/perl, but no /usr/bin/env to find it?
[14:07] <ubitux> how are you supposed to write perl scripts?
[14:18] <michaelni> haiku pod2man uses ---> #!/boot/common/bin/perl
[14:19] <ubitux> you mean the packaged pod2man?
[14:19] <ubitux> they patch each app? :/
[14:19] <michaelni> yes, the pad2man included with haiku or packaged or whatevef
[14:20] <michaelni> but #!perl seems working too on haiku

[16:46] <j-b> http://wiki.videolan.org/Bounties btw
[16:55] <michaelni> j-b, the page doesnt say how much the bounties are ?
[16:56] <j-b> yet
[16:56] <j-b> michaelni: opinions on that?
[16:56] <michaelni> also frame size changing with mt isnt all that hard the hard part is to have it not exploitable
[16:57] <j-b> From a user point of view, hard or not-hard is meaningless: working or not is what matters :)
[16:57] <michaelni> if you just want it working and dont care if its exploitable, i can do that i think
[16:58] <j-b> I think expoitable is not good :)
[16:58] <j-b> but anyway, we are at the 'put money on tasks' part
[16:58] <Compn> you can make another bounty to make it not exploitable
[16:58] <Compn> :P
[16:58] <j-b> and 'gather important taks'
[16:59] <j-b> the -mt parts are probably between 500 and 1000 ?
[16:59] <nevcairiel> I wonder if its worth to try to figure out how to finish my vc-1i patch
[16:59] <Compn> voxware? people still use it ?
[17:00] <j-b> I hope not
[17:00] <Compn> curious why bounty for it :P
[17:01] <j-b> because it was popular in the past
[17:01] <j-b> but true, this will not be a lucrative one :)
[17:01] <Compn> :)
[17:01] <j-b> compared to DTS MA HD...
[17:02] <nevcairiel> technically its DTS-HD MA
[17:02] <nevcairiel> :p
[17:02] <iive> michaelni: about -mt resize. isn't the right way to hold new decoding until all threads with the old size finish? then reinit the codec and start anew?
[17:03] <j-b> nevcairiel: technically, it is crap :)
[17:03] <nevcairiel> crap or not, its t he goto lossless formats for Blu-rays now
[17:03] <nevcairiel> hm typing is off today
[17:04] <j-b> nevcairiel: indeed, hence the presence on the list
[17:04] <Compn> j-b : as for screengrabbing on windows, what about doing it thru ffmpeg ala this patch > http://ffmpeg.org/pipermail/ffmpeg-devel/2011-January/107042.html
[17:04] <j-b> nevcairiel: fixed.
[17:05] <j-b> screen grabbing is done and easy
[17:05] <j-b> the difficulty is audio dekstop grabbing on Win32 and Mac and UI
[17:05] <Compn> oh
[17:05] <Compn> j-b : does loopback mean you can use vlc as a fake webcam ?
[17:05] <Compn> e.g. to play video and upload it using flash client 
[17:05] <j-b> it means you can capture all the audio from your machine
[17:05] <Compn> like the source is a webcam 
[17:06] <Compn> ok i'm thinking of a different thing then :)
[17:06] <Compn> you want 'screen capture'
[17:07] <j-b> audio output capture, if you prefer
[17:07] <j-b> michaelni: if you have any idea on prices and on other missing ideas, please share
[17:08] <nevcairiel> how about java menus for libbluray? or is that coverd in some gsoc somewhere?
[17:08] <Compn> nevcairiel : you mean a wrapper for a jre ?
[17:08] <j-b> BD-J
[17:08] <j-b> hmm, ok
[17:08] <nevcairiel> Compn: its more then that, the support classes in libbluray also lack a lot of implementation
[17:09] <Compn> ok
[17:09] <michaelni> j-b, aac encoder that beats faac , h265 decoder and encoder
[17:10] <nevcairiel> although this might be somewhat self-serving, i'm hoping to work on that part some time in the future unless someone beats me to it. Not that i have a legal entity to ever receive anything. :p
[17:10] <j-b> hevc is not ok, until GSoC is closed.
[17:11] <Compn> libav has h265 porposal
[17:11] <Compn> in gsoc
[17:11] <michaelni> who is student & mentor ?
[17:11] <Compn> i dunno if it was accepted cuz they never updated the wiki
[17:11] <JEEB> the guy has gotten intra decoding to work AFAIK
[17:11] <JEEB> smarter is the student
[17:12] <JEEB> https://github.com/smarter/libav/commits/hevc
[17:12] <j-b> so bounty on top of GSoC is not a good idea :)
