Not able to read Dji tello frames on ubuntu 20.04

[Vaibhav1196]

This is my code, I have also tried adding delays but tit never worked, I received the same result :

############################################################################################

import cv2
from djitellopy import Tello
import time

Initialize Tello and set up video stream

tello = Tello()
tello.connect()
tello.streamon()

time.sleep(5)

frame_read = tello.get_frame_read()

time.sleep(5)

Main loop to continuously read and display frames

while True:
# Attempt to get a new frame from the frame queue
frame = frame_read.frame

# Check if the frame is not None
if frame is not None:
    # Display the frame using OpenCV
    cv2.imshow("Tello Video", frame)

# Check for key press to exit the loop
if cv2.waitKey(1) & 0xFF == ord('q'):
    break

Clean up

cv2.destroyAllWindows()
tello.streamoff()
tello.end()

I use Anaconda environment with :

opencv 4.9
djitellopy latest version

djitellopy 2.5.0 use pyav to decode the stream, pyav and opencv can output the frame well on windows, but has conflict on ubuntu 20.04.
Try pip install djitellopy==2.4.0 on ubuntu.
