Bug#729203: Rebuild of possible FFmpeg reverse build-dependenciesa

[Andreas Cadhalpun <andreas.cadhalpun@googlemail.com>]

Hi,

I have rebuilt the 111 reverse build-dependencies of src:libav currently 
in sid against FFmpeg, by replacing the Libav '-dev' dependencies with 
the appropriate FFmpeg '-ffmpeg-dev' dependencies.
67 of these packages build right away, 13 have a fixed version in 
experimental and 19 can be fixed with more or less trivial patches, 
mainly replacing CodecID with AVCodecID and the like.
Together these are about 89% of the reverse build-dependencies.
From the remaining 12 packages, 8 are RC buggy and probably won't be in 
jessie and 4 depend indirectly (via libopencv-highgui-dev) on Libav 
'-dev' packages, which conflict with the FFmpeg '-ffmpeg-dev' packages. 
Probably libopencv-highgui-dev shouldn't have these dependencies and 
thus I filed bug #745934 about it.

All in all I think it is time to finally get FFmpeg uploaded to the archive.
Unfortunately I haven't heard from Jonathan Dowland in a while, so I'm 
going to ask for a sponsor on debian-mentors.

Best regards,
Andreas
