[12:16:10 CET] <BBB> so whats the status of the AVFrameSideData patches?
[12:16:16 CET] <BBB> Im not sure what Im supposed to do now
[12:54:53 CET] <cone-136> ffmpeg 03Carl Eugen Hoyos 07master:b76df6efb681: lavf/matroskaenc: List subtitle codecs with fake codec_tags to allow remuxing.

[17:15:33 CET] <nevcairiel> fascinating how the avs people manage to break stuff again and again =p

[18:36:07 CET] <Daemon404> these gsoc emails making me frown...
[18:59:15 CET] <cone-136> ffmpeg 03Michael Niedermayer 07master:19321a295a64: avformat/utils: Terminate SPS in avci100_1080i_extradata to avoid warnings during parsing
[19:12:30 CET] <kierank> why does avfilter leave threads lying around
[19:12:36 CET] <kierank> this is insane
[19:13:25 CET] <durandal_1707> Fill bug report
[19:13:58 CET] <kierank> I can't
[19:14:00 CET] <kierank> it's an api bug report
[19:38:30 CET] <jamrial> kierank: if it can't be reproduced with ffmpeg.c, can't you then post a sample program that one can compile to reproduce it?
[19:38:40 CET] <kierank> I think I know why it happens
[19:39:05 CET] <kierank> my fault i think
[19:39:23 CET] <kierank> I'm surprised it did slice threading behind my back
[20:00:46 CET] <nevcairiel> look at t hat, libav found another pet project to annoy devs about, structure packing \o/ gotta squeeze out the last 2 bytes from those pesky codec contexts!
[20:03:06 CET] <iive> i thought that structures are packed so the most common members are in the same cache lines
[20:03:39 CET] <Daemon404> thats hardly an issue with cache sizes nowadays
[20:03:41 CET] <iive> but well, why not make decoders even more slower :)
[20:03:43 CET] <Daemon404> certainly not for a 10 byt struct
[20:04:06 CET] <nevcairiel> 12 with padding!
[20:04:07 CET] <nevcairiel> :P
[20:04:13 CET] <Daemon404> ho ho ho.
[20:04:32 CET] <iive> well, their memory size is even more irrelevant :)
[20:04:43 CET] <nevcairiel> in before they split functionally related parameters because they would create a hole
[20:05:05 CET] <kierank> For big structs like x264_t it is useful
[20:05:14 CET] <nevcairiel> imagine something in the size of h264context with everything ordered by size, instead of functional relationship
[20:05:43 CET] <Daemon404> except that never happened for the big stuff anyway
[20:05:52 CET] <Daemon404> so nit pick about tiny new ones instead
[20:06:10 CET] <iive> i have another proposal!
[20:06:18 CET] <iive> SORT THEM ALPHABETICALLY!
[20:06:31 CET] <Daemon404> you must also pack them though
[20:06:35 CET] <Daemon404> what a fun game it could be
[20:07:07 CET] <iive> well, if you sort by type first, it should come naturally
[20:07:08 CET] <nevcairiel> MS just cheats in their big structs, and issues a pragma to disable member alignment :p
[20:07:23 CET] <nevcairiel> ie. in the dxva structs
[20:07:26 CET] <iive> gcc also have such thing.
[20:07:49 CET] <nevcairiel> of course, same pragma even
[20:08:01 CET] <iive> but it can't work on all architectures and is making code slower.
[22:31:06 CET] <kierank> av500: did you see loongsoon patches
[22:31:13 CET] <kierank> loongsoon got jealous of MIPS
[22:33:24 CET] <nevcairiel> wtf is loongsoon
[22:34:22 CET] <kierank> loongson*
[22:34:26 CET] <kierank> chinese processor
[22:35:38 CET] <nevcairiel> more optimizations noone cares about i guess
[22:36:10 CET] <nevcairiel> as long as its not like crazy mips, where they actually have a different C implementation for mips for some reason, and not asm =p
[22:36:54 CET] <nevcairiel> i wonder what happened to the aac patches, he kind of vanished after he had to bother fixing the mips stuff :p
[22:41:56 CET] <jamrial> some of the alpha optimizations are also c for some reason
[22:44:20 CET] <nevcairiel> carefully crafted C that produces desired code on one specific  compiler
[22:44:23 CET] <nevcairiel> what could go wrong
[23:22:31 CET] <iive> nevcairiel: i think the aac code should be merged
[23:32:51 CET] <BBB> didnt we remove most of these optimizations?
[23:42:57 CET] <kierank> we should probably get rid of TOMI
[23:42:57 CET] <kierank> http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavutil/tomi/intreadwrite.h;h=7dec4158d3cd1578d27e4b3c20a0ba721d1c898b;hb=HEAD
[23:43:40 CET] <kierank> iirc it was some thing by a crazy guy who claimed to be a special forces operative
[23:44:16 CET] <wm4> yep definitely should be part of ffmpeg
[23:44:20 CET] <wm4> moar is better
[23:44:49 CET] <kierank> wm4: yeah, someone might use it
[23:45:03 CET] <kierank> same with segfaulting filters
[23:45:06 CET] <kierank> someone might use it
[23:45:11 CET] <wm4> even if not, it doesn't hurt leaving it in!
[23:51:49 CET] <cone-086> ffmpeg 03Giorgio Vazzana 07master:62e2fae8e402: ffmpeg: fix option name in documentation
