title: Angular JS dynamic ng-src not working in 1.2.0-rc.2
body: <p>I'm trying to implement a video element in an angular JS app and the ng-src won't read the scope variable</p>
  
  <p>I'm using 1.2.0-rc.2</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html ng-app="ngView"&gt;
  
  &lt;head&gt;
     &lt;script src="http://code.angularjs.org/1.2.0-rc.2/angular.min.js"&gt;&lt;/script&gt;
  
     &lt;script&gt;
     var app = angular.module('ngView', []);
     function MyControl($scope){
        $scope.file = '1234.mp4';
     }
    &lt;/script&gt;
    &lt;/head&gt;
    &lt;body ng-controller="MyControl"&gt;
        &lt;video controls  ng-src="http://www.thebigdot.com/{{file}}"&gt;&lt;/video&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>If I use a much older version AngularJS lib, it works. </p>
  
  <pre><code>cdnjs.cloudflare.com/ajax/libs/angular.js/1.0.3/angular.min.js (works)
  </code></pre>
  
  <p>Is this a bug in the latest release or has it been disabled on purpose?  What is the work around ?</p>
