title: getUserMedia frozen at first frame on Android Chrome
body: <p>I have a working code on desktop browsers supporting getUserMedia Api, I can correctly see a video preview of my webcam in the div <code>videoPreview</code>. However, when running on Android device, this same code takes a picture with my front camera when I accept to share it in Chrome browser, then the preview keeps frozen on this first frame.</p>
  
  <pre><code>navigator.getMedia = (navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia);
  
      navigator.getMedia(
          // constraints
          {video:true, audio:false},
  
          // success callback
          function (mediaStream) {
              var video = document.getElementById('videoPreview');
              video.src = window.URL.createObjectURL(mediaStream);
              video.play();
          },   
          //handle error
          function (error) {
              console.log(error);
          }
      )  
  </code></pre>
