title: WebRTC firefox constraints
body: <p>I currently use WebRTC in my personal development, everything works fine. I get the stream from my webcam, but now I want to use constraints for <code>getUserMedia()</code>.</p>
  
  <pre><code>var constraints = {
             audio: false,
             video: {
                 mandatory : {
                       minWidth: 1280,
                       minHeight: 720 
                 }
             }
  };
  </code></pre>
  
  <p>When I test this in Firefox it seems to ignore the constraints. When I test on Chrome or Opera my constraints work fine and my quality is good, anyone know why? The problem is Firefox?</p>
  
  <p>Thanks for you suggestions</p>
