Bug#512844: ffmpeg-debian breaks binary compatibility

[Paul Gevers]

Severity: normal
Thanks

The problem is that you are using mplayer from unstable, with ffmpeg
from experimental. The experimental version of ffmpeg-debian creates
libavcodec52, where your mplayer should depend on if you want to use it.
But the ffmpeg in unstable builds/needs libavcodec51, so that is why
mplayer depends on it. You can at this moment not mix ffmpeg from
experimental with mplayer from unstable.

Maybe ffmpeg should conflict with old versions of the libraries, ie
Conflicts libavcodec51, libavcodec-unstripped-51 etc...
