Vaapi Driver
VAAPI Video Acceleration API provides access to graphics hardware GPU VIDEO_CARDS setting to build driver for dummy video cards fglrx: No.
VAAPI. VAAPI Video Acceleration API is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities for video.

About
The main motivation for VA-API Video Acceleration API is to enable hardware accelerated video decode/encode at various entry-points VLD, IDCT, Motion Compensation etc. for the prevailing coding standards today MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, and VC-1/VMW3. Extending XvMC was considered, but due to its original design for MPEG-2. MotionComp only, it made more sense to design an interface from scratch that can fully expose the video decode capabilities in today s GPUs.
The current video decode/encode interface is window system independent, so that potentially it can be used with graphics sub-systems other than X. In a nutshell it is basically a scheme to pass various types of data buffers from the application to the GPU for decoding or encoding. Feedback on the API is greatly welcomed, as this is intended to be a community collaborative effort.
