[17:46:47 CEST] <ubitux> durandal_1707: opinion on having some lavfi filter-test progs for finer grain tests?
[17:47:20 CEST] <ubitux> i'm back on nlmeans and some code i'm writing is relatively sensitive; i'm currently using an external prog to test very specific part
[17:47:31 CEST] <durandal_1707> ubitux: hmm
[17:47:37 CEST] <ubitux> i'm wondering about integrating that test code inside the filter scoped into a #if TEST ...
[17:48:03 CEST] <durandal_1707> what it tests?
[17:48:33 CEST] <ubitux> it's basically computing a bunch of integrals with all kind of parameters
[17:49:18 CEST] <ubitux> https://github.com/ubitux/FFmpeg/blob/3731bc3872bbf8a870d67196b440cf48aeaaba94/ii.c
[17:49:42 CEST] <ubitux> (not actually doing any test currently, but computing and printing; i'm going to add some checks now)
[17:52:01 CEST] <durandal_1707> integrals, uh oh
[17:52:28 CEST] <ubitux> yeah i was trying to make it possible to make it much faster later on
[17:52:42 CEST] <ubitux> so i had to split boundary area computation from the rest
[17:53:30 CEST] <ubitux> the unsafe version covering most of the area is thus very simple now and relatively easy to simdify
[17:54:01 CEST] <ubitux> i'll need to push it further to have it modN width though, but that will come later 
[17:54:15 CEST] <ubitux> even in C it should be much better
[17:54:37 CEST] <ubitux> anyway, back to the topic, i was planning to have that main() in between TEST ifdefery within the filter
[17:54:46 CEST] <ubitux> so it could be tested specifically
[17:56:57 CEST] <durandal_1707> but?
[17:57:40 CEST] <ubitux> but that will be the first filter to do so
[17:57:48 CEST] <ubitux> so i was just poking
[18:00:27 CEST] <ubitux> i hope to be done with the filter relatively soon btw
[18:00:39 CEST] <ubitux> i just didn't have time to focus on recently
[18:02:28 CEST] <durandal_1707> it could become useful in future
[18:03:11 CEST] <cone-832> ffmpeg 03Rostislav Pehlivanov 07master:c92cc2d559de: aacenc: add a faster version of twoloop as the "fast" coder
[18:03:13 CEST] <cone-832> ffmpeg 03Rostislav Pehlivanov 07master:fb0abb34cb5a: aacenc: unmark the fast coder as experimental
[18:07:08 CEST] <durandal_1707> is vlc ts demuxer better than ours? Sorry if asked already.
[18:13:15 CEST] <durandal_1707> Anybody tried surroundscope? With 5.1 audio.
[18:18:30 CEST] <jamrial> durandal_1707: doesn't vlc use lavf?
[18:19:53 CEST] <durandal_1707> jamrial: not always
[18:20:26 CEST] <ubitux> http://git.videolan.org/?p=vlc.git;a=tree;f=modules/demux/mpeg;hb=HEAD
[18:20:34 CEST] <jamrial> yeah, just looked at the git repo. lavf wrapper but also a bunch of other demuxer
[18:23:14 CEST] <jamrial> heh, custom matroska demuxer. nobody likes lavf's :p
[18:23:27 CEST] <ubitux> ordered chaptering maybe?
[18:23:32 CEST] <jamrial> yeah, most likely
[18:23:55 CEST] <ubitux> i wonder if mpv ended up switching or not
[18:24:00 CEST] <RiCON> atomnuker: "and some may be removed in the future"  should've lost the "some"?
[18:24:43 CEST] <jamrial> i question the need for a custom tta demuxer in vlc, though. it's a very simple format and lavf supports it perfectly
[18:25:07 CEST] <jamrial> guess they wrote it before lavf's was commited and they never bothered to replace it
[18:25:30 CEST] <durandal_1707> ubitux: mpv have own version, lavfilters own, and so on
[18:25:43 CEST] <RiCON> ubitux: https://github.com/mpv-player/mpv/wiki/libavformat-mkv-checklist
[18:25:52 CEST] <ubitux> durandal_1707: yeah i know mpv has its own one, but i remember mpv wondering about switching to lavf one
[18:26:07 CEST] <ubitux> RiCON: ah, there you go; thanks
[18:26:32 CEST] <Compn> we should steal all other demuxers ...
[18:26:34 CEST] <Compn> make wrapper
[18:26:36 CEST] Action: Compn runs
[18:28:03 CEST] <ubitux> Compn: you need to understand that fundamental issues involve api thinking
[18:28:21 CEST] <jamrial> ubitux: doubt it since wm4 was interested in ordered chapters functionality
[18:28:23 CEST] <ubitux> it's not just a bucket in which you throw building blocks code
[18:29:00 CEST] <ubitux> jamrial: according to the wiki it's handled at a higher level; so maybe exporting as side data or whatever may do
[18:29:05 CEST] <Compn> adding more demuxers requires api changes ?
[18:29:06 CEST] <Compn> heh
[18:29:25 CEST] <ubitux> but then again, you probably want to design a side data that can handle more than just matroska
[18:29:49 CEST] <Compn> most players out there (mpv, mplayer, vlc) can use different demuxer libs (lavf, libmatroska, libogg etc)
[18:29:49 CEST] <ubitux> Compn: the reason most players use their own mkv demuxer is because of api limitation
[18:30:19 CEST] <Compn> not just talking about mkv
[18:30:22 CEST] <Compn> but all demuxers
[18:30:38 CEST] <Compn> nevermind
[18:35:46 CEST] <cone-832> ffmpeg 03Rostislav Pehlivanov 07master:6612d0493356: aacenc: fix various typos and an error message
[18:35:50 CEST] <kierank> vlc uses its own demuxes for everything apart from flv afaik
[19:55:11 CEST] <kierank> atomnuker: any idea where we did uyvy -> planar asm?
[19:57:14 CEST] <kierank> ah void ff_uyvy_to_planar_10_c(uint16_t *y, uint16_t *u, uint16_t *v, const uint16_t *l, const int64_t width)
[20:36:54 CEST] <kierank> aballier: https://github.com/kierank/ffmpeg-sdi/blob/master/libavcodec/x86/sdienc.asm#L256
[20:36:58 CEST] <kierank> atomnuker: ^
[20:37:00 CEST] <kierank> what does that SWAP do?
[21:05:01 CEST] <jamrial> kierank: pre processor macro. swaps m1 with m0 for every following instruction
[21:05:13 CEST] <kierank> yes, but why is the question
[21:05:16 CEST] <kierank> as well
[21:05:21 CEST] <jamrial> kinda pointless in this case. the mova bellow could just use m0
[21:05:37 CEST] <kierank> yeah
[21:05:40 CEST] <kierank> might be some cruft
[21:06:16 CEST] <jamrial> guess it was copied from the SBUTTERLFY macro
[21:07:04 CEST] <kierank> maybe
[21:26:18 CEST] <durandal_1707> michaelni: what about adding int64 sample format?
[21:27:41 CEST] <kierank> for audio?
[21:27:43 CEST] <kierank> seriously
[21:28:04 CEST] <durandal_1707> sample was uploaded
[21:28:29 CEST] <durandal_1707> for audiophile killer feature
[21:28:53 CEST] <kierank> link?
[21:41:05 CEST] <durandal_1707> http://trac.ffmpeg.org/ticket/5649
[21:41:43 CEST] <durandal_1707> kierank:^
[21:49:52 CEST] <kierank> omg what a joke
[21:51:57 CEST] <nevcairiel> even as a processing format int64 makes no sense, you would use double then
[22:04:10 CEST] <durandal_1707> its export format like u8
[22:05:51 CEST] <durandal_1707> and its bitexact unlike dbl across platforms
