title: Display a video from a Blob Javascript
body: <p>I would like to display a video from a Javascript Blob/File object in the HTML5 video tag.</p>
  
  <p>This code only works for small videos : </p>
  
  <pre><code>var reader = new FileReader();
  reader.onload = function(e) {
      document.getElementById("video").src=reader.result;
   }
  reader.readAsDataURL(vid);
  </code></pre>
  
  <p>I cannot use this for big videos (> 10MB).
  Is there a solution to display a big video from a blob object in HTML 5?</p>
