This section describes CL-VA (VA-API) interoperability.
|
||||
|
||||
To enable CL-VA interoperability support, configure OpenCV using CMake with WITH_VAAPI=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").
|
||||
|
||||
To use VA-API interoperability you should first create VADisplay (libva), and then call initializeContextFromVA()
|
||||
function to create OpenCL context and set up interoperability.
