title: Access IP camera with OpenCV
body: <p>Can't access the video stream. Can any one please help me to get the video stream. I have searched in google for the solution and post another question in stack overflow but unfortunately nothing can't solve the problem. </p>
  
  <pre><code>import cv2
  cap = cv2.VideoCapture()
  cap.open('http://192.168.4.133:80/videostream.cgi?user=admin&amp;pwd=admin')
  while(cap.isOpened()):
      ret, frame = cap.read()
      cv2.imshow('frame', frame)
      if cv2.waitKey(1) &amp; 0xFF == ord('q'):
          break
  cap.release()
  cv2.destroyAllWindows()
  </code></pre>
