[00:03] <RobertNagy> why does ff_default_get_video_buffer call memset(data[0], 128, i);?
[00:04] <durandal_1707> to maky it gray?
[00:04] <RobertNagy> and why does it do that?
[00:08] <durandal_1707> it is added by michael when merging qatar code
[00:08] <RobertNagy> qatar code?
[00:09] <durandal_1707> libav
[00:09] <RobertNagy> ic
[00:23] <Daemon404> i dont understand how ami_stuff finds all these weird things
[00:24] <durandal_1707> he have bunch of free time
[00:28] <iive> RobertNagy: U/V planes are signed, so this value makes the image color neutral.
[00:28] <iive> using 0, would make it green.
[00:29] <iive> well, not signed, but with offset
[00:36] <llogan> what's the link to Herve's redesigned FFmpeg logo?
[00:40] <RobertNagy> iive: But why make it neutral at all?
[00:40] <RobertNagy> why not just leave it?
[00:40] <RobertNagy> and let the decoder fill it
[00:47] <llogan> llogan: here you go: http://www.movieconverter-studio.com/_PUBLIC/ffmpeg/logo-new/ffmpeg-logo-src/
[00:50] <Daemon404> llogan, btw: https://github.com/dwbuiten/utvideo
[00:50] <Daemon404> may be relevant to you (i recall you building libutvideo)
[00:52] <llogan> Daemon404: thanks. are your patches often accepted by Takeshi?
[00:52] <Daemon404> parts of it for sure
[00:52] <Daemon404> tehred a windows fix in one part
[00:52] <Daemon404> and teh x86 asm works everywhere
[00:52] <Daemon404> x64 asm is bugged on non-windows
[00:52] <Daemon404> and i suck at debugging asm
[00:53] <Daemon404> esp. when gdb tells me teh error happened on the line where a nasm macro was defined
[01:02] <iive> RobertNagy: well, it could be security risk if memory is not cleared. Neutral image is also better than random junk, if part of the frames end up been displayed.
[01:03] <RobertNagy> is there any case where parts of the frame should be possibly displayed?
[01:03] <iive> mainly errors in the bitstream could cause gaps. also there are cases where decoding starts from prediction frame not keyframe.
[01:04] <iive> aka, error resilience.

[01:07] <llogan> modify/mutilate/bikeshed as you see fit (especially License section)
[01:17] <llogan> idiot. i keep s/logo/logan
[01:23] <Daemon404> humm... is it possible for c++ and c symbols to share the same lib??
[01:33] <Daemon404> i see the problem.. an invalid def is being generated
[01:36] <teratorn> Daemon404: god i hope not :(
[01:36] <teratorn> you can link to c symbols from c++

[03:12] <durandal_1707> libavfilter should really have generic options so that ffmpeg -help can show them
[03:13] <durandal_1707> michaelni: libswsresample does not provide options like libavresample
[03:13] <durandal_1707> though avconv doesn't use them
[03:26] <michaelni> durandal_1707, swresample has options and they worked via ffmpeg command line
[03:27] <durandal_1707> but are not shown with -help
[03:29] <durandal_1707> libavresample have api to access AVClass...
[03:29] <durandal_1707> but avconv is not using it at all
[03:44] <durandal_1707> michaelni: qatar is going to bump mayor for lavfi anyway so it may be good time to add priv_class to AVFilter?

[04:06] <michaelni> matrix_encoding ?
[04:06] <durandal_1707> libavresample/options.c
[04:07] <michaelni> ahh the dolby stuff
[04:07] <michaelni> yes i already had planed to port this
[04:07] <michaelni> its trivial
[04:11] <durandal_1707> crap, i cant get lavfi options to show up i keep getting segv
[04:12] <michaelni> about snow, there is some code (and not so little) that assumes h == v subsampling
[04:12] <michaelni> so i might get 444 and gray working but 422 seems harder

[12:26] <saste> ouch, git docs are even worse than ffmpeg's
[12:29] <iive> at least git cli is better than ffmpeg's, but not by much.
[12:36] <cbsrobot> I always thought the gim man pages are exlusively on stackoverflow
[12:36] <cbsrobot> *git
[12:59] <Compn> iive : yes, i think having multiple seperate binaries for each git command is brilliant...
[12:59] <Compn> or maybe i'm thinking of something else
[12:59] <Compn> nevermind
[15:01] <ubitux> saste: any plans on the audio testing?
[15:02] <saste> ubitux: not yet
[15:02] <ubitux> ok
[15:02] <ubitux> it would be nice to have the test in fate/lavfi.mak if possible

[15:04] <saste> this is my ancient patch, don't know if it still works (most likely not)
[15:04] <saste> it was relying on the possibility of having an explicit list of the supported channel layouts

[17:14] <Daemon404> who's the build system expert here?
[17:14] <Daemon404> particularily the mingw side
[17:20] <michaelni> Daemon404, zeranoe or ramiro should know about mingw
[17:21] <Daemon404> ok
[17:21] <Daemon404> neither is ever really on irc... lame

[19:21] <nevcairiel> Daemon404: i looked at the lagarith decoder, and i couldnt find any evidence of such null frames
[19:21] <nevcairiel> but maybe i'm blind
[19:24] <Daemon404> well theyre a thing
[19:24] <Daemon404> maybe we dont implement them
[19:24] <Daemon404> let me look.
[19:24] <nevcairiel> the decoder is fairly simple, i doubt i missed it
[19:25] <nevcairiel> in any case, windows thumbnail generation is fragile on its best days, plain broken on others, so i wouldn't rule out failure on that end :p
[19:25] <Daemon404> nevcairiel, i disbale
[19:25] <Daemon404> cause ms's own decoderts make OTHER APPS crash when they have an open dialogue to a folder with thumbnails
[19:25] <Daemon404> sometimes
[19:25] <Daemon404> its insanely annoying.
[19:29] <Daemon404>     // according to the avi specs, the calling application is responsible for handling null frames.
[19:29] <Daemon404>     if ( compressed_size == 0 ){
[19:29] <Daemon404>         #ifndef LAGARITH_RELEASE
[19:29] <Daemon404>         MessageBox (HWND_DESKTOP, "Received request to decode a null frame", "Error", MB_OK | MB_ICONEXCLAMATION);
[19:30] <Daemon404>         #endif
[19:30] <Daemon404>         return ICERR_OK;
[19:30] <Daemon404>     }
[19:30] <Daemon404> well there u go
[19:30] <nevcairiel> oh yeah i think avformat doesnt send null frames out
[19:30] <nevcairiel> if its really size 0 without anything else
[19:30] <nevcairiel> in any case, nothing in the avcodec decoder
[19:32] <Daemon404> yeah
[19:34] <aquarat> is H.264 MVC (3D) video supported in ffmpeg or being worked on ?
[19:34] <aquarat> and hello
[19:34] <nevcairiel> no, and not to my knowledge
[19:35] <nevcairiel> of course you never know what some developer is cooking up in his private repo somewhere
[19:35] <aquarat> should I create a request for it ?
[19:35] <aquarat> and upload samples
[19:35] <aquarat> lol @ cooking
[19:36] <michaelni> samples are welcome if there are none yet
[19:36] <michaelni> a patch would be great too ;)
[19:37] <aquarat> I only really know Java :P
[19:41] <JEEB> http://c.learncodethehardway.org/
[19:42] <aquarat> mmm
[19:44] <aquarat> looks cool
[19:44] <aquarat> and it's free
[19:44] <aquarat> I'll read it ;)
[19:44] <aquarat> thanks
[19:46] <JEEB> no problem, also you might want to start looking at some of the simpler video decoders and possibly format parsers
[19:47] <ramiro> hi
[19:48] <Daemon404> hi
[19:48] <aquarat> I've played a bit with wav decoding
[19:48] <aquarat> and I wrote an application in Java that generated sine waves modulated with time for my watch
[19:49] <aquarat> I live in a country that doesn't have a long wave time transmitter
[19:50] <Daemon404> ramiro, you are fimiliar with the mingw aspect of teh build system, right?
[19:50] <ramiro> yep
[19:50] <Daemon404> how do we generate our .def files?
[19:50] <ramiro> well i was until early last year
[19:51] <ramiro> gcc generates them
[19:51] <Daemon404> hmm shit.
[19:51] <Daemon404> when i link libutvideo, which has c++ mangled symbols, teh def files only contains the mangled c++ symbols (all of 2!) and ignores the rest of the normal C ones
[19:51] <Daemon404> even though theyre all present, and exported from the dll
[19:51] <Daemon404> i dont really know how to go about fixing this
[19:52] <ramiro> the line that configures to make the def file is in configure: SHFLAGS='-shared -Wl,--output-def,$$(@:$(SLIBSUF)=.def) [...]
[19:53] <ramiro> I don't know how it works for c++. so this is a libutvideo issue, not ffmpeg, right?
[19:57] <Daemon404> ramiro, no
[19:57] <Daemon404> it's a ffmpeg issue
[19:57] <Daemon404> it hapopens with any c++ 
[19:57] <Daemon404> like libstagefright
[19:59] <ramiro> hm, let me see. if you link against any c++ library, the ffmpeg dlls export c++ symbols only, is that right?
[20:00] <Daemon404> ramiro, no
[20:00] <Daemon404> teh dlls themselevs export teh c symbols too
[20:00] <Daemon404> at least when i checked
[20:00] <Daemon404> the .def and teh .dll.a onyl have teh c++ symbols
[20:00] <ramiro> ah, ok
[20:01] <ramiro> i remember digging into binutils' source code and the function that created the .def file was really stupid
[20:04] <Daemon404> probably
[20:05] <ramiro> http://sourceware.org/cgi-bin/cvsweb.cgi/src/binutils/dlltool.c?rev=1.106&content-type=text/x-cvsweb-markup&cvsroot=src
[20:05] <ramiro> gen_def_file
[20:08] <Daemon404> right... binutils sitll uses cvs
[20:08] <ramiro> heh
[20:09] <ramiro> it does cplus_demangle(). I have no idea what that does, but it looks like it should demangle the symbol name
[20:09] <ramiro> can you pastebin the output you get?
[20:09] <Daemon404> the resulting .def?
[20:14] <ramiro> yes
[20:17] <Daemon404> let me rerun it
[20:41] <Daemon404> ramiro, https://dl.dropbox.com/u/77349181/avcodec-54.def
[20:42] <ramiro> that's it?
[20:42] <Daemon404> yup.
[20:42] <Daemon404> those are the 2 c++ symbols i called through libavcodec*.cpp
[20:43] <Daemon404> i think
[20:43] <ramiro> that's odd
[20:43] <ramiro> is this in the ffmpeg tree? or some code you're working on?
[20:44] <ramiro> i don't know what libutvideo, but if it's a lib that you can compile into ffmpeg then i guess zeranoe has fixed whatever issue happens with it
[20:44] <Daemon404> tthats ffmpeg tree
[20:44] <Daemon404> ramiro, iy only happens with --enable-shared --disable-static
[20:45] <Daemon404> https://dl.dropbox.com/u/77349181/dll_nm.txt
[21:11] <ramiro> Daemon404: maybe ask the mingw-w64 guys? they know gcc inside out
[21:11] <Daemon404> me and them dont see eye-to-eye a lot
[21:11] <Daemon404> lets just put it that way
[21:12] <ramiro> hahaha
[21:12] <ramiro> too bad. i think they're nice people
[21:13] <ramiro> then ask zeranoe, he might know
[21:13] <Daemon404> the yhave communication issues (lack of native english speakers)
[21:13] <Daemon404> ill ask zeranoe maybe
[21:25] <ubitux> michaelni: is it me or AV_QSORT comparison is inverted?
[21:26] <ubitux> it looks like it is sorting the exact opposite of qsort()

[21:36] <ubitux> ARGH
[21:36] <ubitux> no shit niggah...
[21:36] <ubitux> that could be actually very useful...
[21:37] <ubitux> it might be better to propose a buffersrc & buffersink struct instead of asking for the user to build a string.

[22:10] <michaelni> ubitux, what is leaking exactly ?

[22:12] <michaelni> what is silly on that ?
[22:12] <ubitux> i think it should be global, but that's more like an api issue

[22:36] <michaelni> ubitux, wheres the problem ?

[22:38] <ubitux> i'm trying this on top of the branch
[22:38] <ubitux> but i may be doing something wrong
[22:38] <ubitux> you can try make fate-subtitles to see the result
[22:39] <ubitux> or well, maybe just: ffmpeg -i ~/fate-samples/sub/JACOsub_capability_tester.jss out.ass
[22:46] <michaelni> ubitux, fixed
[22:47] <ubitux> does it pass make fate-subtitles?
[22:48] <michaelni> didnt try
[22:48] <michaelni> i just diffed the .ass file
[22:48] <michaelni> and it matches
[22:49] <ubitux> ok
