I'm glad you ask. The solution to this problem we've come up [1], and
that has been sucessfully implemented in ubuntu 8.10 is to provide a
tricky shlibs file and replacement packages. Packages that get build
against the ffmpeg package produce dependencies like this:

libavcodec51 (>= 3:0.svn20080206-8) | libavcodec-unstripped-51 (>= 3:0.svn20080206-8)

The libavcodec-unstripped-51 package then conflicts/replaces the
libavcodec51 package, since it installs the "uncrippled" version of

[1] well, the idea came originally from Loïc Minier, and I've
implemented and tested it.

To answer your question: If you have packages that depend on the
"uncrippled" version of ffmpeg, you install a shlib.local file
overriding the alternate dependency.

I'm aware of that. I'm very interested in collaboration with you because
of that. I do hope that the trickery with the replacement packages and
the alternate dependencies allow us to provide a common and maintainable
packaging across distributions and extra repositories like
debian-multimedia.org and medibuntu.org.
