35 The <application>libva</application> package contains a library which
36 provides access to hardware accelerated video processing, using hardware
37 to accelerate video processing in order to offload the central
38 processing unit (CPU) to decode and encode compressed digital video. VA
39 API video decode/encode interface is platform and window system
40 independent targeted at Direct Rendering Infrastructure (DRI) in the X
41 Window System however it can potentially also be used with direct
42 framebuffer and graphics sub-systems for video output. Accelerated
43 processing includes support for video decoding, video encoding,
44 subpicture blending, and rendering.
