In the case of debian it would be a 3rd party (debian-multimedia.org).

I for one an highly in favour of what is being done, and despise
when projects start demanding which versions of libraries to use, and
linking staticly.  It's pathetic.  If the libraries are that flacky
and unstable, they should be fixed (or not used), and if they are not,
then it should work with any version that is at least at a certain known
good enough revision.

We don't need the bloat of staticly linked applications, and shared
libraries mean only one version of a library needs fixing when a bug or
security problem is found, rather than having to recompile a bunch of
staticly linked applications.
