title: embed video in html page and make it play any video file in local drive
body: <p>I want to embed video in html page sothat I can play any multimedia file from my hard drive or from a url.I tried to create a web page with </p>
  
  <pre><code>&lt;video src="test.mp4" controls width="320" height="240"&gt;
  
  &lt;/video&gt;
  </code></pre>
  
  <p>In <code>chrome</code>,the video plays without any problem.
  However,the mp4 file is not recognized in <code>firefox</code> .It displays error message- <code>'no video with supported format or mimetype found'.</code></p>
  
  <p>It so happens that most of my video files are <code>.mp4 or .flv</code> files.</p>
  
  <p>If I put 
  <code>&lt;source src="test.flv" /&gt;</code>  in the video element ,then both chrome and firefox fail to show it.</p>
  
  <p>So,what should I do to play <code>at least mp4 and flv files in both browsers</code>?.</p>
  
  <p>Any pointers /advice most appreciated.</p>
