Super simple video implementation of DJI tello drone (very little code)

It has been a year since the DJI tello drone came out, and the function of viewing videos with PCs was only opened this year. After 2 days of exploration, it was finally realized in a simple way. I dare not enjoy it alone and share it.

1. Connect to the wifi of tello:

2. Use the udp component to send the open video stream command "streamon"

       IdUDPClient1.Host:='192.168.10.1';
       IdUDPClient1.Port:=8889;
       IdUDPClient1.Active:=True;
       IdUDPClient1.Send('command');
       IdUDPClient1.Send('streamon');//Open the video

3. Run ffplay in ffmpeg to view the video: enter "ffplay -f h264 udp://0.0.0.0:11111" in cmd

4. Display the results (with a delay of about 2 seconds, not very clear)

5. Turn off the video stream "streamoff"

       IdUDPClient1.Host:='192.168.10.1';
       IdUDPClient1.Port:=8889;
       IdUDPClient1.Active:=True;
       IdUDPClient1.Send('command');
               IdUDPClient1.Send('streamonoff');//Off video
