无法在 ubuntu 22 上从 DJI Tello 获得直播

Question

我正在尝试使用 DJI Tello 无人机进行实时视频流，最初我能够在 Windows 机器上运行相同的代码，但是当我在 Ubuntu 22 上尝试时，我无法获得任何用于实时流媒体的 opencv 弹出窗口。

这是代码的输出：

base) nirbhay@nirbhay:~/Desktop/Tello_code$ python LiveStream.py

这是代码：

from djitellopy import tello
import cv2
import time
#import libh264decoder

drone = tello.Tello()
drone.connect()
print("Drone Battery Percentage:")
print(drone.get_battery())
print("Live Stream Address:")
print(drone.get_udp_video_address())

drone.streamon()

while True:
    img=drone.get_frame_read().frame
    #print("image:",img)
    img=cv2.resize(img,(660,420))
    cv2.imshow("Image",img)
    #time.sleep(3)
    cv2.waitKey(1)

    #time.sleep(1)

python包列表和版本：

djitellopy                    2.5.0
opencv-python                 4.9.0.80
