The FFmpeg team ensures that the 0.8 series is API/ABI compatible with
Libav 0.7.
Good to know.

We will need both versions. FFmpeg 0.8 for gst-ffmpeg 0.10.12 and VLC
1.2.0 when released (MPlayer I'm not sure if support the new API). 0.7
for everything else (VLC 1.1.x, ffmpeg2theora 0.28, etc).
What makes you so sure current ffmpeg-0.7 using apps / libs
won't work with a simple recompile with ffmpeg-0.8? AFAIK
only API additions have been done, as well as some deprecated
functions removed. So if an app does not use these deprecated
functions it should be a matter of a simple recompile, right?
And if they do use those deprecated functions, maybe it can
be fixed with a simple patch?
I'm not necessarily in favor of maintaining 2 versions in
parallel.

gst-ffmpeg 0.10.12 will not compile with old FFmpeg API. It needs the new one.
Right, but doesn't the 0.7.2 release offer most of the new API?
Perhaps that is enough?
