如何保持我的无线摄像头信号源打开？

如何解决如何保持我的无线摄像头信号源打开？

我试图在 PyQt5 窗口中读取来自 Ip 网络摄像头的读取视频源，但它似乎无法保持打开状态。有时它会播放录像，但会突然关闭。

我已经测试过从我的网络摄像头播放提要，效果很好。

代码如下：

from PyQt5 import QtCore,QtGui,QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import cv2 as cv
import numpy as np
import urllib.request
