Нужно использовать библиотеку av:

def get_image_from_stream(stream_url: str) -> np.ndarray:
    '''
    Get last frame from stream using av modul.
    '''
    container = None
    try:
        container = av.open(stream_url) # sadad
    except Exception:
        # quit
        raise Exception("ERROR! Stream not working!")
    
    video_stream = next(s for s in container.streams if s.type == 'video')
    
    image_pil = None
    for packet in container.demux(video_stream):
        for frame in packet.decode():
            image_pil = frame.to_image()
            
            if image_pil:
                break
        if image_pil:
            break
    image = np.asarray(image_pil)
    return image

stream_url у вас уже есть. А функцию просто запускайте в бесконечном цикле.
