title: OpenCV with Network Cameras
body: <p>I'm using openCV 1.1pre1 under Windows.
  I have a network camera and I need to grab frames from openCV. That camera can stream a standard mpeg4 stream over RTSP or mjpeg over http.
  I've seen many threads talking about using ffmpeg with openCV but I cannot make it work.</p>
  
  <p>How I can grab frames from an IP camera with openCV?</p>
  
  <p>Thanks</p>
