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.
