title: using HTML5 video tag in a simple rails app
body: <p>inside index.html.erb there is the following code   </p>
  
  <pre><code>&lt;video width="320" height="240" controls="controls"&gt;
        &lt;source src="truffle1.mp4"/&gt;
   Your browser does not support the video tag.
  &lt;/video&gt;
  </code></pre>
  
  <p>I am not sure where to put my mp4 video file so I put it at several places.<br>
  Next I fire up the rails server and use Chrome to open the index page.  I see the black video frame but it does not play.  and when I try open video in a new window. I get
  No route matches [GET] "/admin/truffle1.mp4" 
  (note admin is just the namespace for the controller). </p>
  
  <hr>
  
  <p>seems like this is a rails routing problem... </p>
