Re: [Libquicktime-devel] [PATCH] Add another IMX fourcc

[Joseph A. <jo...@mi...>]

Hi,

Here is another patch for (read only) Avid IMX support. Being an Avid 
format, it uses Avid's proprietary atoms to switch between different YUV 
range mappings. That's now supported. Another thing I changed is 
stopping taking the height from tkhd and instead take it from stsd.
I came across a file that had:
720x480 in tkhd
720x486 in stsd
720x512 (including the VBI area) coming out of ffmpeg.
The file was made with Avid Media Composer 6. It was crashing the 
current version of libquicktime.

BTW, I found more incompatibilities with the latest ffmpeg from git. 
Looks like they've done a big spring cleanup in their interfaces.
I haven't done anything to address those yet.
