[00:17] <bcoudurier> what filter_complex proposal ?
[00:19] <bcoudurier> ubitux, just implement the right way from the start
[00:55] <CIA-17> ffmpeg: 03Carl Eugen Hoyos 07master * r76c79aa28f 10ffmpeg/ (libavcodec/raw.c libavformat/nut.c): 
[00:55] <CIA-17> ffmpeg: Support yuva444p rawvideo in nut.
[00:55] <CIA-17> ffmpeg: Fixes ticket #1058.
[01:25] <jb_far> ffv1 stores 10bits in 16bits chroma?
[02:24] <FishB8> Just wanted to drop in here to say, that if anybody is interested in playing with a sample of the Sony SR codec, (from the F65 camera) a sample file is available from the Mango Project
[02:24] <FishB8> http://mango.blender.org/production/format-woes/
[02:32] <kierank> "MXF (again, this would not be readable for FOSS)"
[02:32] <kierank> why not
[02:32] <kierank> what's wrong with FOSS reading mxf
[02:33] <j-b> yeah
[02:34] <j-b> EXR?
[02:44] <FishB8> I think the statement about not being readable with FOSS was in reference to the video steam contained in it rather than demuxing MXF itself
[02:48] <Compn> FishB8 : well we are interested, thanks for sample
[02:49] <Compn> it'd be really nice if someone would actually take the time for a proper bugreport, just a simple ffmpeg -i sample.exr out.avi would suffice
[02:49] <Compn> i'm guessing we'll hit resolution limit bug and some other things
[02:49] <Compn> well resolution limit isnt a bug but ... yeah
[02:50] <Compn> guess i can stick it in the ole ffmpeg bug tracker
[02:50] <Compn> j-b : can vlc handle those samples ? :)
[02:50] <j-b> not tested
[02:50] <j-b> and I do not really care. :)
[02:50] <FishB8> I don't think ffmpeg supports OpenEXR
[02:55] <Compn> mm
[02:55] <Compn> theres a patch
[02:56] <Compn> michaelni : what do you say about taking over the openexr patch and doing a security review on it ?
[02:56] <Compn> michaelni : http://ffmpeg.org/pipermail/ffmpeg-devel/2010-April/081747.html
[03:00] <Compn> hmm wheres stefano
[03:13] <Compn> FishB8 : i put exr bug ticket in , you can follow it here > https://ffmpeg.org/trac/ffmpeg/ticket/1172
[03:19] <FishB8> Nice. Would make the workflow of getting from EXR to DCP a little less crazy.
[05:46] <CIA-17> ffmpeg: 03Baptiste Coudurier 07master * re636aa1a56 10ffmpeg/libavformat/ (isom.c mov.c): 
[05:46] <CIA-17> ffmpeg: movdec: handle 0x7fff langcode as macintosh per the specs
[05:46] <CIA-17> ffmpeg: The correct point that seperates ISO and MAC language codes is 0x400
[05:46] <CIA-17> ffmpeg: according to the current QT spec. Old QT specs did not list where this
[05:46] <CIA-17> ffmpeg: seperation is but apparently only defined the meaning of the first 137.

[14:00] <Compn> michaelni : wow. you work fast. :) 
[14:01] Action: Compn sends mail to jimmy christensen asking if any of his other patches were missed
[14:02] <ubitux> should we make a "playground fate" system for ppl with slow machines?
[14:03] <ubitux> (a repository where you push, and a hook call fate, report the results, and reset to its old state or sth like this)
[14:06] <Compn> do you mean so multiple machines can submit to the same test? or ?
[14:08] <ubitux> i'd say the report is made available for a while (or sent my email or sth)
[14:08] <ubitux> but maybe it's not worth the effort

[14:14] <ubitux> mmh and of course the typedef could be removed as well actually.

[14:44] <michaelni> kierank, do you have some spec about s302m or can you explain how the channel maping is supposed to work ?
[15:02] <kierank> there is no channel mapping
[15:02] <kierank> it's that simple
[15:04] <michaelni> how is s302m presented to the user if theres no channel mapping anywhere ?
[15:07] <nevcairiel> isnt it essentially a studio/mastering codec? maybe the people using it are supposed to know wtf they are doing? :)
[15:14] <kierank> yes the user decides how to map the channels
[15:16] <michaelni> kierank, in this case the question still is what is wrong with the patch setting the most likely layout ?
[15:16] <michaelni> i mean if the user has to override it anyway 
[15:17] <kierank> nothing i suppose as long as the user can override it easilyt
[15:17] <michaelni> it doesnt make the patch or previous addition of layouts correct sure ...
[15:17] <michaelni> but also doesnt really seem to worsen things
[15:19] <ubitux> couldn't we just call av_get_default_channel_layout()? does it belong to the decoder?
[15:20] <michaelni> i think the default for 8 channels is different 
[15:22] <ubitux> is it less appropriate than the arbritrary choosen one here?

[15:24] <michaelni> i dont know, i suspect what is in s302m.c would represent what is most likely to occur in real world s302m
[15:24] <michaelni> or at least thats what should be in it
[15:28] <ubitux> yeah right, ok
[18:55] <ubitux> what's the common solution to pass a decode option to the generic decode functions?
[18:56] <ubitux> add a field in the AVCodecContext?
[18:56] <ubitux> mmh seems to be sth like this&
