title: Videojs - how to add a custom icon in the control bar
body: <p>I am using the videojs library to build a player audio.
  I would like to add the custom component, such as an image, in the control bar, before the play button.</p>
  
  <p>I read how to add a custom button:</p>
  
  <pre><code>var button = videojs.getComponent('Button');
  var closeButton = videojs.extend(button, {
      constructor: function() {
          button.apply(this, arguments);
      },
      /*  handleClick: function() {
          this.player().dispose();
      }*/
  });
  </code></pre>
  
  <p>But it doesn't work to add image.
  Somebody can help me?
  Thanks a lot</p>
