This section describes Intel VA-API/OpenCL (CL-VA) interoperability.
To enable basic VA interoperability build OpenCV with libva library integration enabled: -DWITH_VA=ON
(corresponding dev package should be installed).
To enable advanced CL-VA interoperability support on Intel HW, enable option: -DWITH_VA_INTEL=ON
(OpenCL integration should be enabled which is the default setting). Special runtime environment should be set up in order to use this feature: correct combination of libva, OpenCL runtime and media driver should be installed.
Check usage example for details: samples/va_intel/va_intel_interop.cpp
