To enable CL-VA interoperability support, configure OpenCV using CMake with WITH_VA_INTEL=ON . Currently VA-API is
supported on Linux only. You should also install Intel Media Server Studio (MSS) to use this feature. You may
have to specify the path(s) to MSS components for cmake in environment variables: VAAPI_MSDK_ROOT for Media SDK
(default is "/opt/intel/mediasdk"), and VAAPI_IOCL_ROOT for Intel OpenCL (default is "/opt/intel/opencl").
