Is there any reason why a commercially licensed libx264 would not
be GPL-compatible?
AFAICT the commercial license is basically "everything is still GPL
code, but we relieve you of some of the restrictions that the GPL poses
on you".
In that case the commercial libx264 can still be legally linked
against absolutely anything the GPL one can.
Admittedly there is the point that it is pointless, and probably
that they will have to offer source for libx264 despite having
a commercial license.
Maybe it's better to just disallow it anyway in order to avoid confusion...
