As I stated before, I still don't have hardware to work on the 3d side of things, which most drivers need to do XvMC. So, I'm not sure if the openchrome ddx is able to pull this off somehow, but I doubt it. The client needs to be able to send the stream directly to the hardware. It is looking like there may be wider support for VDPAU in the not too distant future.
