Merge pull request #19755 from mikhail-nikolskiy:ffmpeg-umat
cv::UMat output/input in VideoCapture/VideoWriter (data stays in GPU memory) * FFMPEG with UMat input/output * OpenCL_D3D* context * fix Linux build * cosmetic changes * fix build if USE_AV_HW_CODECS=0 * simplify how child context pointer stored in parent context * QSV interop with OpenCL on Windows * detect_msdk.cmake via pkg-config * fix av_buffer_ref() usage * revert windows-decode-mfx whitelisting; remove debug msg * address review comments * rename property to HW_ACCELERATION_USE_OPENCL * fix issue with "cl_khr_d3d11_sharing" extension not reported by OpenCL GPU+CPU platform * core(ocl): add OpenCL stubs for configurations without OpenCL * videoio(ffmpeg): update #if guards * Put OpenCL related code under HAVE_OPENCL; simplify reuse of media context from OpenCL context * videoio(test): skip unsupported tests - plugins don't support OpenCL/UMat yet - change handling of *_USE_OPENCL flag * videoio(ffmpeg): OpenCL dependency * videoio(ffmpeg): MediaSDK/oneVPL dependency * cleanup, logging * cmake: fix handling of 3rdparty interface targets Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>
