Sorry, I have no idea. All the patches I tried on Mac had only very
basic or no pix processing but played back and displayed fragment of
quite a few videos.
And right now (nor in the near future) I don't have access to a Mac to
do more tests.
I thought the bottleneck was in reading and/or decoding the files rather
than rendering, but now I can't remember what made me think that (if
there was a good reason at all).
