va: Add VA_SURFACE_ATTRIB_USAGE_HINT_EXPORT This can be used to tell the driver to prepare the surface such that it can easily be used for export to third-party APIs. For example, the driver might choose to decode to frames instead of fields since only frames can be exported.
Libva is an implementation for VA-API (Video Acceleration API)
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.
