#i124875# avoid avmedia build problems with multiple active backends

MacAVF files have been renamed so that both can be active concurrently.

#i124875# avoid wasteful loading of an AVAsset in MacAVF::Framegrabber

is often very data-intensive this should and can be avoided by using the
movie asset already available in the Player.
