I want to use OpenCV by branching the deepstream pipeline. We are using Python Binding Deepstream. I want to use Deepstream to infer the input of the webcam, and to input the signal split by appsink to OpenCV. webcamera -->DeepStream → ObjectDetection |---------->appsink---->opencv–>cv2.imshow …

You can pass a gst pipeline string to OpenCV like this: uri = "rtsp://1.2.3.4/stream" gst_str = "rtspsrc location={} ! application/x-rtp, media=video ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=BGRx ! videoconvert ! video/x-raw, format=BGR ! appsink".format(uri) vid…
