Hi, Please refer to the python sample: import sys import cv2 def read_cam(): cap = cv2.VideoCapture("filesrc location=/home/nvidia/sample_1080p_h264.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=BGRx ! videoconvert ! video/x-raw,format=BGR ! appsink ") w = cap.get(cv2.CAP_PROP_FRAME_WIDTH) h = cap.get(cv2.CAP_PROP_FRAME_HEIGHT) fps = cap.get(cv2.CAP_PROP_FPS) print('Src opened, %dx%d @ %d fps' % (w, h, fps)) gst_out = "appsrc ! video/x-…
