OpenCV and Python

+Starting with L4T 32.2.1 / JetPack 4.2.2, GStreamer support is built in to OpenCV. +The OpenCV version is 3.3.1 for those versions. Please note that if you are using +earlier versions of OpenCV (most likely installed from the Ubuntu repository), you +will get 'Unable to open camera' errors. +
+If you can open the camera in GStreamer from the command line, and have issues opening the camera in Python, check the OpenCV version. + +``` +>>>cv2.__version__ +``` +
