[00:02] <ubitux> thx
[00:03] <ubitux> iirc the notation for excluding 10 is [0,10)
[00:03] <ubitux> in english math litterature
[00:03] <nevcairiel> thats what I remember, [] and (), not <>
[00:04] <ubitux> i tend to pref the [0;10[ notation though
[00:04] <ubitux> but well, that's not valid english :p

[10:56] <cone-944> ffmpeg.git 03Clément BSsch 07master:7c3941b25ce0: avfilter/lut3d: support 3DLUTSIZE directive for Davinci files.
[12:28] <wm4> --enable-debug doesn't seem to add debug infos to shared libs
[12:28] <wm4> bug?
[12:28] <nevcairiel> isnt enable debug default on
[12:28] <wm4> perhaps
[12:29] <nevcairiel> i dont suppose it produces _g libraries as well, eh
[12:30] <wm4> apparently not
[12:30] <wm4> but it strips them on install
[12:30] <wm4> god, why
[12:30] <nevcairiel> can always run --disable-strip if you want to
[12:31] <nevcairiel> i dont debug gcc builds, and msvc doesn't have that problem
[12:31] <wm4> it's not like this is a gcc issue
[12:31] <wm4> it just means msvc support is different from gcc support
[12:31] <nevcairiel> because msvc has debug symbols in its own file!
[12:32] <wm4> well, ffmpeg could do that too in its build process
[12:32] <nevcairiel> is that a thing for gcc/gdb flows?
[12:32] <wm4> AFAIK yes
[12:32] <wm4> or what are you asking
[12:33] <nevcairiel> i just dont know if thats something supported, debug symbols in a separate file, for other mainstream compilers
[12:33] <wm4> could be a problem for other obscure cc-conform compilers
[12:34] <nevcairiel> i think i remember seeing an option in my gentoo box for that, called split-debug or something, i had to turn that on some time ago when i was valgrinding some things
[12:36] <nevcairiel> but i'm really not the right person to ask how to handle debuging linux binaries
[12:38] <wm4> actually it's --disable-stripping
[13:37] <cone-944> ffmpeg.git 03Michael Niedermayer 07master:928e2a7d6476: doc/codecs: document ignore_err
[13:37] <cone-944> ffmpeg.git 03Michael Niedermayer 07master:d7ade20adb71: avcodec: add AV_EF_IGNORE_ERR
[13:37] <cone-944> ffmpeg.git 03Michael Niedermayer 07master:e94b08f00217: avformat: add AV_EF_IGNORE_ERR
[13:37] <cone-944> ffmpeg.git 03Michael Niedermayer 07master:336901e0601e: avcodec/h263dec: use AV_EF_IGNORE_ERR
[14:48] <Compnn> [flv @ 0290a600] Stream discovered after head already parsed
[14:48] <Compnn> blurgh
[15:08] <cone-944> ffmpeg.git 03Lukasz Marek 07master:c9a12fdd2d29: lavf/mux: pass options to nested structs of priv data
[17:17] <Daemon404> eta till aac ticket hits 300?
[17:19] <nevcairiel> Daemon404: 16
[17:20] <Daemon404> nevcairiel, i meant time
[17:20] <nevcairiel> i can do it in an hour
[17:20] <Daemon404> lol
[17:21] <Daemon404> so 5 minutes + 55 minutes for loading trac 16 time
[17:21] <Daemon404> s
[17:21] <Daemon404> ;)
[17:21] <nevcairiel> but the latest patch at least sounds like it might be near commit worthy
[17:21] <Daemon404> yeah
[17:21] <Daemon404> still is losing to LAME nad FAAC though, no?
[17:21] <Daemon404> at least it wont be considered a weapon of mass ear destruction anymore though
[17:23] <nevcairiel> i've been using the encoder in git master right now to on-the-fly transcoding for mobile streaming, and my eyes didn't fall of at least
[17:23] <nevcairiel> the v8 patch got M/S encoding, and i didnt see a full quality comparison since then in the ticket anymore though
[17:24] <Daemon404> yeah
[17:24] <Daemon404> not that it matters for me, since we dont distro
[17:24] <Daemon404> i can just use fdk
[17:25] <Daemon404> what do you use it for? s/pdif?
[17:26] <nevcairiel> hls streaming to android
[17:26] <Daemon404> oh you mean at work
[17:26] <Daemon404> i assume
[17:26] <nevcairiel> well i also use the feature :d
[17:26] <nevcairiel> but yes
[17:28] <nevcairiel> fwiw, aac over s/pdif is very rarely supported, if you want to encode for that, you use ac3 typically
[17:29] <JEEBsv> funny enough various Japanese hardware seems to support it, it was then abused by the early Japanese DTV cappers: capping the output pictures via a capture card, and pushing AAC in S/PDIF for audio
[17:29] <JEEBsv> thus you got the original audio
[17:30] <nevcairiel> i know its in the spec, but thats pretty much the end of what i've seen of it
[17:30] <nevcairiel> the spec even has atrac though
[17:31] <JEEBsv> lol
[17:31] <JEEBsv> that's pretty fabulous alright
[17:32] <nevcairiel> i've only bothered to implement the usual consumer formats, not sure any of my devices would even accept anything else
[17:32] <nevcairiel> maybe wma
[17:33] <wm4> you implemented spdif mangling yourself?
[17:33] <Daemon404> a lot of pc setups use s/pdif
[17:33] <Daemon404> ffdshow had bitstreaming iirc
[17:33] <nevcairiel> nah i just use avformats spdif "muxer", but to use it properly, I had to understand how it works, it was weird at first
[17:34] <nevcairiel> (and still needs a bit of glue around it to make it talk to windows audio)
[17:34] <wm4> I'm using that muxer thing too
[17:35] <wm4> weird indeed
[17:35] <nevcairiel> once i knew how it worked, its works OK
[17:36] <nevcairiel> but DTS-HD and TrueHD required to read the code to figure out how it does its thing and what it wants from me
[17:40] <Daemon404> nevcairiel, standard libav*
[18:31] <cone-944> ffmpeg.git 03Carl Eugen Hoyos 07master:a64df19c5bd2: Disable inline_asm_direct_symbol_refs if lto was requested.
[18:31] <cone-944> ffmpeg.git 03Carl Eugen Hoyos 07master:431c7bd3f49e: Map --enable-lto to -ipo when compiling with icc.

[18:33] <Daemon404> http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=c25b0b7788644036b6507322a111004a1eac3142 <-- wut
[18:35] <wm4> he wrote some patches or so
[18:35] <Daemon404> for icl
[18:36] <Daemon404> nevermind the people who actually wrote msvc support? :V
[18:37] <michaelni> Daemon404, feel free to add yourself to MAINTAINERs for msvc or if someone else wants to (co)-maintain it ...
[18:39] <michaelni> i just applied Matthews patch which added himself as maintainer for ICL & MSVC, there was noone else listed for these in maintainers before
[18:45] <michaelni> also i certainly prefer too if MSVC is maintained by the people who wrote the support, so if they agree please add them or send a patch that adds them to maintainers
[18:51] <michaelni> also, everyone please, if you want to maintain something, please make sure you are listed for it in the MAINTAINER file
