Thinking aloud here, could you use this with x11rdp to improve video 
playback? That is implement the Xvideo extension, grab the YUV data sent 
to the "card" re-compress using JPEG (libjepg and libjpeg-turbo have 
entry points for compressing YUV data) and spit out to the RDP client?

I guess there could be issues with scaling at the client end?

I was under the impression that RemoteFX was not about reducing 
bandwidth, but about providing GPU support, and USB redirection. The 
codec bit of RemoteFX was as I understood it to provide a fast 
high-fidelity experience for both video and text with optional GPU 
acceleration of the compression.

Or am I missing something?
