   SDL can blit YV12 and IYUV surfaces. See src/video/quartz/ in the
sources, especially SDL_QuartzVideo.m.

   VLC has support for SDL, but TTBOMK people only use the native OS X
video output, which uses QuickTime to display the YUV surfaces. The code
is in plugins/macosx/ (0.4.x versions) or modules/gui/macosx/ (0.5.x CVS
version of VLC).
