+The main motivation for VAAPI (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.
