title: Youtube videos are not streaming in <video> of HTML5
body: <p>I'm trying to stream youtube videos with  tag, the videos uploaded were .mp4 and supports h.246 codecs.</p>
  
  <p>Code snippet as below,</p>
  
  <pre><code>&lt;html&gt;    
  &lt;body&gt;    
  &lt;video control autoplay&gt;    
  &lt;source src="http://www.youtube.com/watch?=RB_hVB6qzBc" type="video/mp4" codecs="h.264"&gt;&lt;/source&gt;    
  &lt;/video&gt;    
  &lt;/body&gt;    
  &lt;/html&gt;    
  </code></pre>
  
  <p>This page is not displaying any video neither in Chrome - WINDOWS XP or in Chrome on Android 2.3.</p>
  
  <p>The  tag is working fine when we point the source to an video url of amazon cloud.  </p>
  
  <p>We are facing this problem only when same video accessed via Youtube.</p>
  
  <p>Do source of  mandates extension like .mp4 etc to play a media file ? Because other than this accessing a video from amazon and accessing it over Youtube are just the same.</p>
  
  <p>Help of this is greatly appreciated.</p>
  
  <p>Thanks.</p>
