|
|
This VA-API video driver backend provides a bridge to the GEN GPUs through
|
|
the packaging of buffers and commands to be sent to the i915 driver for
|
|
exercising both hardware and shader functionality for video decode,
|
|
encode, and processing.
|
|
VA-API is an open-source library and API specification, which provides
|
|
access to graphics hardware acceleration capabilities for video
|
|
processing. It consists of a main library and driver-specific acceleration
|
|
backends for each supported hardware vendor.
