[Beignet] beignet-openCL and libva/VAAPI

[Nikita Orlov]

Hi!

I will try. But in my task I need, not post-processing, but pre-processing.
I mean at first I am processing frame via some OpenCL kernel and than put it to encoder.
Now I am downloading frame from GPU and than putting it to libva.
Is it possible with this versions to skip downloading in pre-processing case?
