Which video formats does the vb.net web browser control support and why won't it play this video even if it works in IE?

I have this html in my web browser control:

<html>
   <body>
      <video width="450" height="400" controls autoplay="autoplay">
         <source src="file:///C:\Rythm\*name*.mp4" type="video/mp4">
         Votre navigateur ne prend pas en charge ce format vidéo.
     </video>
   </body>
</html>

Of course, *name* is replaced with the video's actual name. The code works in chrome and IE, but not in the web browser control. How can I fix this?

Another solution for adding a video stored on the user's hard drive to a vb.net form would alternatively also be appreciated.

Solution

The issue might be caused by that WebBrowser in VB.NET doesn't use IE 11 by default. I try to add this line in html <head>, then it can work with WebBrowser in VB.NET:

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Sample HTML code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <title></title>
</head>
<body>
    <video width="450" height="400" controls autoplay="autoplay">
        <source src="file:///C:\Rythm\*name*.mp4" type="video/mp4">
        Votre navigateur ne prend pas en charge ce format vidéo.
    </video>
</body>
</html>

Result in VB.NET Form:
