Here are the source code

net = jetson_inference.detectNet(
    model=model_path, 
    labels=labels_path,
    input_blob='input_0',
    output_cvg='scores',
    output_bbox='boxes', 
    threshold=threshold
    )

camera = cv.VideoCapture(0)
camera.set(3, 640)
camera.set(4, 480)

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi @TrickyCV, does your cv.VideoCapture() program work on it’s own? Not sure this is related to jetson-inference. What does ls /dev/video* show for you?
