As unfortunate as this is, most applications that uses those libraries
are packaging their own copy of ffmpeg for a few reasons:

- ffmpeg APIs break (on point releases) too much
- Depending on the distro's copy of ffmpeg is very unreliable because of
said point releases
- libav (another project)/ffmpeg incompatibilities (I know you mentioned
this but numerous amount of people are probably still using libav by
default)

So basically I think you would have to propose inclusion of a version of
ffmpeg into Wine's source to get the green-light (and update as
necessary). Otherwise there will be a lot of new bug reports of crashes
landing in a probably stripped copy of the system's ffmpeg or libav,
with users not knowing how to give good information for debugging.

Just my 2 cents.
