Mikhail Nikolskii 7bcb51eded Merge pull request #19460 from mikhail-nikolskiy:videoio-hw ... videoio: HW decode/encode in FFMPEG backend; new properties with support in FFMPEG/GST/MSMF * HW acceleration in FFMPEG backend * fixes on Windows, remove D3D9 * HW acceleration in FFMPEG backend * fixes on Windows, remove D3D9 * improve va test * Copyright * check LIBAVUTIL_BUILD >= AV_VERSION_INT(55, 78, 100) // FFMPEG 3.4+ * CAP_MSMF test on .mp4 * .mp4 in test * improve va test * Copyright * check LIBAVUTIL_BUILD >= AV_VERSION_INT(55, 78, 100) // FFMPEG 3.4+ * CAP_MSMF test on .mp4 * .mp4 in test * .avi for GStreamer test * revert changes around seek() * cv_writer_open_with_params * params.warnUnusedParameters * VideoCaptureParameters in GStreamer * open_with_params * params->getUnused * Reduce PSNR threshold 33->32 (other tests use 30) * require FFMPEG 4.0+; PSNR 30 as in other tests * GStreamer AVI-demux plugin not installed in Ubuntu test environment? * fix build on very old ffmpeg * fix build on very old ffmpeg * fix build issues * fix build issues (static_cast) * FFMPEG built on Windows without H264 encoder? * fix for write_nothing test on VAAPI * fix warnings * fix cv_writer_get_prop in plugins * use avcodec_get_hw_frames_parameters; more robust fallback to SW codecs * internal function hw_check_device() for device check/logging * two separate tests for HW read and write * image size 640x480 in encode test * WITH_VA=ON (only .h headers used in OpenCV, no linkage dependency) * exception on VP9 SW encoder? * rebase master; refine info message * videoio: fix FFmpeg standalone plugin build * videoio(ffmpeg): eliminate MSVC build warnings * address review comments * videoio(hw): update videocapture_acceleration.read test - remove parallel decoding by SW code path - check PSNR against the original generated image * videoio: minor fixes * videoio(test): disable unsupported MSMF cases (SW and HW) * videoio(test): update PSNR thresholds for HW acceleration read * videoio(test): update debug messages * "hw_acceleration" whitelisting parameter * little optimization in test * D3D11VA supports decoders, doesn't support encoders * videoio(test): adjust PSNR threshold in write_read_position tests * videoio(ffmpeg): fix rejecting on acceleration device name mismatch * videoio(ffmpeg): fix compilation USE_AV_HW_CODECS=0, add more debug logging * videoio: rework VideoAccelerationType behavior - enum is not a bitset - default value is backend specific - only '_NONE' and '_ANY' may fallback on software processing - specific H/W acceleration doesn't fallback on software processing. It fails if there is no support for specified H/W acceleration. * videoio(test): fix for current FFmpeg wrapper Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>		4 years ago
