Hi everyone I have problem with RTSP live streaming

Here is code of stream :

def stream_rtsp(request, rtsp_id):
    port, id = rtsp_id.split()
    rtsp_url = f'rtsp://{GLOBAL_IP}:{port}/{id}'
    cap = cv2.VideoCapture(rtsp_url)
    print('camera opened')
    def video_stream():
        while True:
            ret, frame = cap.read()
            if not ret:
                break
            # print('framing')
            target_size = (960, 720)
            frame = cv2.resize(frame, target_size)
            _, buffer = cv2.imencode('.jpg', frame)
            send_event('test', 'rtsp', {'buffer': buffer.tobytes()})
            yield (b'--frame\r\n'
                   b'Content-Type: image/jpeg\r\n\r\n' + buffer.tobytes() + b'\r\n')
        cap.release()
    return StreamingHttpResponse(video_stream(), content_type="multipart/x-mixed-replace; boundary=frame")

Is there any ways to did it? Channels? Or maybe you already have that kind of problem how you solve it?

Put the data in a message and send it with Channels over a websocket? That’s what I would do without researching anything about it. So far the connection seems very stable to me, from my experiments with Channels.
