Hi,
Please check if you can run this gst-launch-1.0 command:

gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! videoconvert ! video/x-raw,format=BGR ! fakesink

If yes, please apply this pipeline:

v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! videoconvert ! video/x-raw,format=BGR ! appsink

to cv2.VideoCapture().
