RyoheiHagimoto 0:0e0631af0305 30 This section describes Intel VA-API/OpenCL (CL-VA) interoperability.
RyoheiHagimoto 0:0e0631af0305 31
RyoheiHagimoto 0:0e0631af0305 32 To enable CL-VA interoperability support, configure OpenCV using CMake with WITH_VA_INTEL=ON . Currently VA-API is
RyoheiHagimoto 0:0e0631af0305 33 supported on Linux only. You should also install Intel Media Server Studio (MSS) to use this feature. You may
RyoheiHagimoto 0:0e0631af0305 34 have to specify the path(s) to MSS components for cmake in environment variables: VA_INTEL_MSDK_ROOT for Media SDK
RyoheiHagimoto 0:0e0631af0305 35 (default is "/opt/intel/mediasdk"), and VA_INTEL_IOCL_ROOT for Intel OpenCL (default is "/opt/intel/opencl").
RyoheiHagimoto 0:0e0631af0305 36
RyoheiHagimoto 0:0e0631af0305 37 To use CL-VA interoperability you should first create VADisplay (libva), and then call initializeContextFromVA()
RyoheiHagimoto 0:0e0631af0305 38 function to create OpenCL context and set up interoperability.
