title: No video with supported format and MIME type found in Firefox with HTML5 video
body: <p>I'm trying to insert a video, using HTML5.</p>
  
  <p>I have the following markup:</p>
  
  <pre><code>&lt;video id="video" loop="" controls="" preload=""&gt;
      &lt;source src="portada_2.mp4" type='video/mp4;codecs="avc1.42E01E, mp4a.40.2"'/&gt;
      &lt;source src="portada_2.webm" type='video/webm;codecs="vp8, vorbis"'/&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>but when I open the page in Firefox, it shows me the following message:</p>
  
  <blockquote>
    <p>No video with supported format and MIME type found</p>
  </blockquote>
