title: VP9 WEBM video support in EDGE browser
body: <p>I see that EDGE claims VP9 codec support in the latest versions by enabling the VP9 in MSE in their browser configuration.</p>
  
  <p>I tried doing that and still, it doesn't work and it throws an error saying this type of video file isn't supported.</p>
  
  <p>I had launched the <a href="https://html5test.com/compare/browser/mybrowser.html" rel="nofollow noreferrer">https://html5test.com/compare/browser/mybrowser.html</a> URL in the EDGE browser and this says VP9 is not supported in the browser and in the same time youtube videos are streamed in WebM vp9 codec(used stats for nerds to check this).</p>
  
  <p>I am using this in my HTML file </p>
  
  <pre><code>&lt;video&gt;
      &lt;source src="http:/url/123.webm" type="video/webm"/&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>Youtube's <a href="https://www.youtube.com/html5" rel="nofollow noreferrer">https://www.youtube.com/html5</a> claims that it can play MSE &amp; WEBM vp9,  and it is able to play vp9 videos, is there any difference in the way a request is served by the server for vp9 and MSE &amp; vp9.</p>
  
  <p>I am able to play the VP9 video in chrome and firefox without any issue.
  Thanks in advance for the help.</p>
