Question

当我尝试从 IP 摄像机捕获视频时，我正在进行活动检测，它显示错误。代码 =

import cv2

cap=cv2.VideoCapture('http://38.101.209.29:8082')

while True:
    ret,frame =cap.read()

    cv2.imshow('frame',frame)
    if cv2.waitKey(1)&0xFF ==ord('q'):
        break
cap.release()
cv2.destroyAllwindows()

错误回溯是

Traceback (most recent call last)

      5     ret,frame =cap.read()
      6 
----> 7     cv2.imshow('frame',frame)
      8     if cv2.waitKey(1)&0xFF ==ord('q'):
      9         break
