title: MIME type found and No video with supported format
body: <pre><code>&lt;video width="320" height="240" controls loop&gt;
      &lt;source src="movie/Wildlife.mp4" type="video/mp4"&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>I wrote this code but it's not working and shows no video with supported format and MIME type found. It's not working for any browser I've tested, including firefox version is 26.0, what should I change?</p>
