title: JWPLAYER not working on IE11
body: <p>On a SharePoint 2010 website I'm using jwplayer for the streaming of some videos.</p>
  
  <p>Below is the code I included in SharePoint:</p>
  
  <pre><code>&lt;!-- JW Player Library --&gt;
  &lt;script src="http://jwpsrv.com/library/MCK8hplLEeOY0CIACmOLpg.js"&gt;&lt;/script&gt;
  
  &lt;div id='playerKXSDPIwKERSb'&gt;&lt;/div&gt;
  
  &lt;!-- Script to display video file in the player div --&gt;
  &lt;script type='text/javascript'&gt;
      jwplayer('playerKXSDPIwKERSb').setup({
          // URL to the video file
          file: 'http://localhost/SiteAssets/Pages/testvideo/video.mp4',
          // URL to the image that should be shown before the video is started
          title: 'Video',
          width: '50%',
          aspectratio: '16:9'
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>Is working perfect on Chrome and Edge but not working on IE11.</p>
  
  <p>On the javascript console I obtain the following errors:
