 expect that this logic will be needed?

 while some distribution have reverted their decision to use LibAV and are
 now back to FFmpeg (in particular debian and ubuntu); some are still using

 I don't want to have to guess on who does what; we have a universal binary
 for all available distribution, it needs to work *everywhere*.

 I'll probably end up doing what you're suggesting, but it's a major pain.
