Is it? Say Fedora provides ffmpeg-free-0.6, rpmfusion provides
ffmpeg-all-0.6, presumably making sure it obsoletes ffmpeg-free, that
might work. But then ffmpeg-free-0.7 is released, and there's ABI
breakage so applications are updated at the same time, but now updates
are blocked, because of ffmpeg-all-0.6.

This looks like it would be a package maintenance hell.

How? Having two separate packages? I don't think that would fly on
many distributions.

According to you.
