You can refer to

Nano not using GPU with gstreamer/python. Slow FPS, dropped frames

Hi, Attached a sample for reference. Please follow the steps: 0. Install CUDA, tegra_multimedia_api samples through sdkmanager Down the script [s]https://github.com/AastaNV/JEP/blob/master/script/install_opencv4.1.1_Jetson.sh[/s] JEP/install_opencv4.5.0_Jetson.sh at master · AastaNV/JEP · GitHub Add the option and execute the script to build OCV4.1.1 -D OPENCV_GENERATE_PKGCONFIG=YES Execute $ sudo ldconfig -v Build and run the sample ~/gst_cv_gpumat$ CUDA_VER=10.0 make Compiling: gs…

It demonstrates NVBuffer → EGLImage → CUeglFrame → cv::cuda::GpuMat.
