title: MP4 file not playing in firefox - whats a good video alternative?
body: <p>I cannot get my mp4 video to play in Firefox - it simply says " No video with supported format and MIME type found".  Here's my HTML...</p>
  
  <pre><code>&lt;video poster="images/video.png" width="100%"  controls autoplay&gt;
  &lt;source src="images/polutionbbc.mp4" class="videoplayer" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' /&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>The video plays well in other browsers. I have read other similar questions here on Stackoverflow and some people are saying that FF just will not play mp4 video at all due to licensing... </p>

  <p>That assumed therefore, could anybody please suggest either a fix or an alternative video format that plays universally across browsers and how I would convert it?</p>
  
  <p>I am hosting with hostgator and I have checked the list of mime types and mp4 is listed there so I dont think it is that.</p>
