I see you posted to the Quicktime mailing list.  That is probably your
best bet.  Me asking would unfortunately get into grey areas around IP
rights.

Transform.flip would be quite slow.  Probably your best bet for speed
if it can't be done within Quicktime would be to copy the image
flipped from the Quicktime buffer to the Surface.  As in, if the user
requests flipped, iterate through the rows normally on the copy, but
copy from the last column to the first column in each row.  At this
point though, using Transform.flip would be much quicker to implement,
so you may want to do that and focus on fixing the other stuff.

Someone posted a patch to do something similar earlier:

To check performance problems, try using the cProfile module to see
what functions it is slowing down on.
