Python 如何使用cv2.VideoCapture接收tello udp流

我尝试使用cv2.VideoCapture接收电视流，但它总是在这一步停止

capture=cv2.VideoCapture（'udp:/0.0.0:11111'，cv2.CAP\u FFMPEG）

“udp:”后面应该有两个斜杠，而不是一个

---

比如：'udp://0.0.0.0:11111“

检查以确保流链接有效。在VLC播放器中打开它以确保它工作。看一看，我试着使用ffplayudp://192.168.10.2:11111 你是怎么让它工作的udp://192.168.10.2:11111? udp地址不应该是udp://0.0.0.0:11111 ??

import socket
import time
import cv2

tello_ip = '192.168.10.1'
tello_port = 8889
tello_address = (tello_ip, tello_port)
mypc_address = (host, port)
socket = socket.socket (socket.AF_INET, socket.SOCK_DGRAM)
socket.bind (mypc_address)
socket.sendto ('command'.encode (' utf-8 '), tello_address)
socket.sendto ('streamon'.encode (' utf-8 '), tello_address)
print ("Start streaming")
capture = cv2.VideoCapture ('udp:/0.0.0.0:11111',cv2.CAP_FFMPEG)
if not capture.isOpened():
    capture.open('udp:/0.0.0.0:11111')

while True:
    ret, frame =capture.read()
    print(ret)
    if(ret):
        cv2.imshow('frame', frame)
    if cv2.waitKey (1)&0xFF == ord ('q'):
        break
capture.release ()
cv2.destroyAllWindows ()
socket.sendto ('streamoff'.encode (' utf-8 '), tello_address)
