title: vlc-qt: rtsp stream with authentication required
body: <p>I am using vlc-qt to get the video stream from a camera protected by authentication.</p>
  
  <p>Doing a test with cameras unauthenticated the code works fine and the video stream is displayed correctly.</p>
  
  <p>In those that require authentication instead, specifying the url as:</p>
  
  <p><strong>rtsp://username:password@ipaddress/p1.mp4</strong></p>
  
  <p>authentication will not be accepted.</p>
  
  <p>Did I forget something or is there some other method to authenticate?</p>
