/**
* Native bindings to the intel_va_api_media_sharing extension.
*
* The goal of this extension is to provide interoperability between OpenCL and the cross-platform Video Acceleration API (VA API). The extension
* specifically enables sharing of VA API surfaces for media. It uses similar mechanisms and provides similar surface sharing capabilities for VA API that
* are provided by the Khronos OpenCL 1.2 Media Surface Sharing extension for DX9.
*
* Requires {@link CL12 CL12} and a VA API implementation supporting sharing of surfaces with OpenCL.
