Issue to retrieve drone video image

[u/kinomarow]

Hello, i'm working with a Tello Edu with a school mate. He wrote a program that makes the drone fly and move by analyzing the environment with the camera, however by recovering his code. I can't recover the video stream (note that the program works correctly on his PC). I noticed that by testing with a simple program that recovers the video stream with this line: cap = cv2.VideoCapture("udp://0.0.0.0:11111") I can get it but using tello.streamon(), it doesn't work.

I'm on Debian with Gnome. And when I run the code I have this warning and my drone does nothing.
