X Video acceleration for Kdenlive?

Oh please oh please oh please.....

This would be amazing to be able to tap into with Kdenlive:

I'm guessing though that this would come in via one of the upstream projects (ffplay?)
Still it would be amazing to start thinking about what might be needed to take advantage of this kind of functionality when it's available to us. Does anyone know if Nvidia supports XVMA yet?
