uri 警告中缺少端口:使用 Python OpenCV cv2.VideoCapture() 打开文件时出错 [英] Port missing in uri warning: Error opening file with Python OpenCV cv2.VideoCapture()

问题描述

当我尝试流式传输 ipcam 时，我遇到了如下所示的错误

I got a blunder as depicted beneath when I endeavor to stream ipcam

"[tcp @ 000000000048c640] uri 中缺少端口警告:打开文件时出错 (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:901)"

"[tcp @ 000000000048c640] Port missing in uri warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:901)"

import numpy as np
import cv2
cv2.__file__
cap = cv2.VideoCapture('http://admin:password@http://192.168.1.***/')
#cap = cv2.VideoCapture('https://www.youtube.com/watch?v=Mus_vwhTCq0')

while(True):

    ret, frame = cap.read()
    try:
     cv2.resizeWindow('Stream IP Camera OpenCV', 120300, 800)
     cv2.imshow('Stream IP Camera OpenCV',frame)
    except  Exception as ex:
        template = "An exception of type {0} occurred. Arguments:\n{1!r}"
        message = template.format(type(ex).__name__, ex.args)
        print  (message)

    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()
