[00:23] <ubitux> durandal11707: use comma for aliases
[00:26] <durandal11707> ubitux: what?
[00:27] <ubitux> for asetpts
[00:27] <ubitux> @item S, NB_SAMPLES
[00:27] <ubitux> otherwise it means 2 differents things with similar semantics
[00:28] <ubitux> (such as x and y)
[00:32] <cone-25> ffmpeg.git 03Michael Niedermayer 07master:2e2b6d7ab37d: fate: Adjust filter-trim-time parameters
[03:24] <ubitux> michaelni: so you added a rootkit in sws with xyz support! you evil!
[03:44] <michaelni> ubitux, for a moment you scared me ... ;)
[03:56] <ubitux> yeah rest assured, it seems the rootkit wasn't really spotted yet
[03:56] <ubitux> we just know there is one
[04:11] <BBB> xyz is inherently evil, bc conversion requires linearization
[04:11] <BBB> I wrote some code for that at some point, you guys just use luts I suppose?
[04:13] <michaelni> yep, the code uses luts, and iam not too happy about that
[04:15] <BBB> I tried other approaches and they were slower
[04:15] <BBB> and yes they were simd
[04:16] <BBB> with fairly limited precision
[04:16] <BBB> but you can make the luts be generated through the simd, then it's pretty cool
[04:16] <BBB> (luts in 19bit intermediates are kinda slow to generate)
[04:20] <cone-25> ffmpeg.git 03highgod0401 07master:f685aee18f7a: lavu/opencl: fix the compile bug on linux
[04:21] <BBB> if you want I'll see if I can release the code for that stuff
[04:21] <BBB> shouldn't be a big deal
[04:22] <michaelni> if its faster and or more precisse it would be interresting
[04:23] <BBB> than luts? no it isn't :(
[04:23] <BBB> assuming you make the luts 8bit through a general pow() floating point call
[04:23] <BBB> maybe with haswell it gets faster
[04:24] <michaelni> maybe we could put more than 1 sample in a LUT
[04:25] <michaelni> adjacent pixels have similar colors so the table doesnt need to be x^2 sized
[04:25] Action: michaelni tries to stay awake but fails
[10:42] <j-b> good moroning
[10:44] <j-b> lol @MSE bug
[10:44] <michaelni> morning
[10:45] <michaelni> btw, that git irker thing still has issues with commit messages containiung '|' or something
[10:45] <j-b> o_O
[10:45] <j-b> don't use |  then :)
[10:45] Action: j-b runs
[10:46] <michaelni> libav uses it alot lately it seemss
[10:46] <michaelni> so when merging we use it too ...
[10:46] <j-b> ok
[10:46] <j-b> I'll ask thresh
[10:47] <michaelni> thanks

[13:13] <ubitux> _please
[13:16] <ubitux> durandal_1707: pickplanes
[13:17] <ubitux> pp already taken :(
[13:17] <durandal_1707> but really. filters named with only two letters .......
[13:18] <J_Darnley> Why is the length of a filter name a problem?
[13:18] <ubitux> durandal_1707: "plane" could be ok too btw
[13:18] <ubitux> but extractplanes is fine, really :p
[13:19] <iive> deplane
[13:19] <ubitux> 13:10:34 <@durandal_1707> deplane
[13:19] <iive> argh...
[13:19] <iive> ok, deplane wins
[13:20] <iive> is there plane_split?
[13:20] <durandal_1707> channelsplit
[13:20] <iive> consistency is good thing.
[13:20] <iive> (if you don't go diego with it).
[13:21] <ubitux> iive: your sentence is not ordered alphabetically
[13:21] <iive> lol

[18:22] <michaelni> j-b, according to carl above should have been the last known/vissible interlaced vc1 bug
[18:22] <JEEB> yay
[18:23] <nevcairiel> oh right, i wanted to run my test files through it
[18:23] <nevcairiel> is it bitexact to reference now?
[18:23] <michaelni> no
[18:23] <michaelni> i made no attempt to make it bitexact
[18:23] <nevcairiel> is the loopfilter still missing for interlaced?
[18:24] <michaelni> yes i think so but it seems not to lead to any vissible difference according to carl
[18:24] <michaelni> at least for the files he looked at
[18:25] <nevcairiel> i'll build git master and see if i can find a file with issues
[18:25] <michaelni> ok
[18:35] <durandal_1707> should i wait saste for asetps doc patch?
[18:36] <cone-418> ffmpeg.git 03Paul B Mahol 07master:ce322f4c191f: extractplanes filter
[18:41] <j-b> michaelni: no way?
[18:47] <cone-418> ffmpeg.git 03Stefano Sabatini 07master:f51aa92b0f16: lavfi/testsrc: add support for color interactive command
[19:17] <cone-418> ffmpeg.git 03Paul B Mahol 07master:e6d4e687558d: lavu: add planar 16 bit and 8 bit rgb with alpha
[19:58] <michaelni> j-b, i didnt investigate what effects not doing loop filtering could have, it likely can lead to vissible effects
[19:58] <michaelni> If someone reports a case where it does show artifacts then ill look into implementing it
[20:01] <j-b> http://streams.videolan.org/issues/6365/0002_vc1_notworking.m2ts
[20:01] <j-b> http://streams.videolan.org/issues/5887/

[20:05] <nevcairiel> those seem all to play fine
[20:05] <tempusfol> Hello, I've encountering some problems compiling ffmpeg. I've tried #ffmpeg, I got no answer after pasting my ./configure and full logs. My I discuss about that here?
[20:05] <tempusfol> s/My/May/
[20:18] <durandal_1707> tempusfol: i dont see logs on #ffmpeg
[20:19] <tempusfol> durandal_1707: I've posted there 3 hours ago.
[20:19] <durandal_1707> found it
[20:23] <cone-418> ffmpeg.git 03Paul B Mahol 07master:b937d3694e54: doc/filters: document asetpts in single place
[20:26] <durandal_1707> so nobody cares for broken ilpack and softpulldown?
[20:28] <durandal_1707> the ilpack have some inline assembly that could be used in fieldmatch
[20:31] <durandal_1707> i could teach trim filters to use AV_OPT_TYPE_DURATION
[21:38] <durandal_1707> ubitux: how is 3d lut going?
[21:52] <ubitux> durandal_1707: in progress
[21:53] <ubitux> mostly done TBH
[21:53] <ubitux> but i'm working on several other things, please be patient :)
[23:11] <trose> looking for some info about pipe2image png support
[23:11] <trose> anyone know how to make this work or is it not supported?
[23:36] <cone-356> ffmpeg.git 03Michael Niedermayer 07master:e756635964ed: eamad: Check against minimum supported dimensions
