I'm not so proficient with rpm, in portage-speak there is the concept of 
virtual and I guess deb has the same thing.

rpm doesn't have ffmpeg-$version that is aliased to ffmpeg-all 
ffmpeg-free so that once you have a package requiring ffmpeg-$ver the 
resolver will pick whatever satisfies the requirement within the virtual

slot and virtual (depending if you want one to replace the other or one 
stay aside the other)
