Saving video with python biding DeepStream

[mam1680]

Hi I have a question: I want to save the video with deepstream_test1.py and I add this part to my code:

    sink = Gst.ElementFactory.make("filesink", "filesink")
    if not sink:
        sys.stderr.write(" Unable to create file sink \n")

    sink.set_property("location", "./out.mp4")
    sink.set_property("sync", 1)
    sink.set_property("async", 0)

but it keeps running after 4 frames and won't stop (like it is in an infinite loop) what's the problem?

To save mp4 video you need: nvvideoconvert (caps format=I420) -> nvv4l2h264enc -> h264parse -> qtmux -> filesink.
