This is almost 100% the case -- the ffmpeg/ffprobe binary names are
the same, and the static library names are the same.  The dynamic lib
names carry a version number and should/will change if an
incompatibility arises.

It currently doesn't make sense to enable both packages at once, so
I'll try to add that to the buildroot patch.
