video_effect.py sample code not working

[nakataniyota]

hi.

I noticed that container = av.open(drone.get_video_stream()) never returns. Can anyone point out potential area to debug this?

`drone.connect() drone.wait_for_connection(60.0)

    retry = 3
    container = None
    while container is None and 0 < retry:
        retry -= 1
        try:
            container = av.open(drone.get_video_stream())
            #av.container.open(drone.get_video_stream())
            print("OPEN AV")`

log attached:
