DJI Tello drone SDK cmd mode UDP video stream recive issue

I bought this drone which I can easily remote control. I have done the UDP remote control and receive data, and it work fine. Now I want to get the video stream, and I used the video stream in top. I set up the URL as “rtsp://0.0.0.0:11111”, which I don’t know is that right format or not.
So I also put the English vision of tello SDK documentation here. Could you guys please help find out how to get the video stream of tello drone.
