title: getUserMedia() permission denied
body: <p>I am trying to test out screen sharing using <code>getUserMedia()</code>. I have Chrome version 28 and the <code>getUserMedia()</code> screen capturing flag enabled, yet I still get permission denied errors.</p>
  
  <p>On this <a href="http://simpl.info/screencapture/" rel="noreferrer">screen capture demo</a>, I get the following error:</p>
  
  <blockquote>
    <p>getUserMedia error:  NavigatorUserMediaError {code: 1, PERMISSION_DENIED: 1} </p>
  </blockquote>
  
  <p>While, on <a href="https://html5-demos.appspot.com/static/getusermedia/screenshare.html" rel="noreferrer">this screen capture demo</a>, I get the following demo:</p>
  
  <blockquote>
    <p>PERMISSION_DENIED. Are you no SSL?</p>
  </blockquote>
  
  <p>I never got any prompts about sharing when visiting the sites. Why does my browser deny permission to screen share?</p>
