Browse Source 
This doesn't cause any changes to the contents of the output path (apart
from the $out reference changing due to the modified expression).

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.
