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