Because it needs to render RGB data on top of the video, which can't be done sanely if you're
using a YUV overlay. Not to mention the fact that most hardware only lets you use one overlay
at once.

It can be done. schismtracker, which only uses RGB, converts this to YUV2 using SDL, and I can
live with that. Throwing in a video should be a no brainer.

I am aware of that limitation. On dedicated embedded appliances, we know there is only one
Flash drawing window open at any time, so it would be a big win. As for the home user, Adobe
could simply start out with X11 output for all video windows and add an option to the
right-click menu to enable Xv on a specific window so that at least the main window of Youtube
where many-fps video actually plays can be accelerated.
