That's what I thought as well. however there are some cases where the
API did change. We collect such bugs here:

http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=pkg-multimedia-maintainers@lists.alioth.debian.org&tag=ffmpeg-needs-porting

Currently I'm aware of one API change in ffmpeg, namely a change in the
structure AVFormatParameters. It used to have a member 'device' but that
was dropped.

Maybe I have missed it, but would it be possible to document such API
changes in a changelog for FFmpeg downstream developers with some hints
how applications should be adapted?

There are currently two packages known to be affected by the
AVFormatParameters change, but I've seen some more affected packages in
ubuntu because of that.
