I'm working with the Blackmagic DeckLink cards and this is
unfortunately the only frame buffer format that their hardware
supports when capturing VANC (for Captions and AFD data).
I convert it to 8-bit planar YUV 422 or 420 before doing
much work with it, but ideally I would like to do that in
swscale so others could benefit instead of in my own routines.

Heh, I'm no fan of Apple after trying to work with QuickTime
for the last three months. Their documentation leaves much to
be desired and they have their own terminology for everything.
