You know I just figured out that the pixel packing for DVCPRO-HD is
reversed from what we use in GEM. That causes a Quicktime routine to
kick in which eats about 40% of my CPU here. It's only a change to two
lines of code to get the proper format, but it would require all of the
pix_objects to be rewritten!
So looks like I may have guessed wrong back in Fall of 2002 when
picking pixel formats. Oh damn. This could be something CoreVideo
would sort out.
