Hi,
Attached a sample for reference. Please follow the steps:
0. Install CUDA, tegra_multimedia_api samples through sdkmanager

  1. 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
  2. Add the option and execute the script to build OCV4.1.1
-D OPENCV_GENERATE_PKGCONFIG=YES
  1. Execute
$ sudo ldconfig -v
  1. Build and run the sample
~/gst_cv_gpumat$ CUDA_VER=10.0 make
