As you probably know, ffmpeg supports versioned executables, installdirs 
etc.

Building an ffmeg2* package which is installable in parallel to ffmpeg 
actually is pretty straight forward. Building a parallel installable 
ffmpeg2-devel, would be more difficult, though. However, provided 
packages are being built in chroots/mock/koji, these days, I do not see 
a pressing need for a parallel installable ffmpeg2-devel.

AFAIU, as long as these packages are properly linked (and not libraries 
not being dlopened), package deps on SONAMEs would conflict and thus 
prevent such problems.
