(I'm not familiar with this kind of hardware, having only dealt with
color-key based overlays myself).
Figuring out when you could use this particular capability in the
current framework would be pretty tricky, I suspect you'd have to expose
it to the compositing manager and let it set things up when possible.
A lot of the use cases I've seen place graphics translucently over the
video though, which doesn't seem like it will work here.
