Description:
VDPAU-based backend for VA API
The VA-API (Video Acceleration API) enables 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). It provides an interface to fully expose the video decode capabilities in today's GPUs. . This package contains the VDPAU-based backend driver for use with the VA API library.
