How to use HTML5 video control from ASP.Net code behind?

Hello,

I have the following code with .aspx page.

Code:-

<video id="VideoPlayer" src="<%=ResolveUrl("~/Videos/Butterfly.mp4") %>" controls="true"
width="400" height="350" loop="true" runat="server"/>

Please let me know how to set its video url from code behind of the vb.net.


Thanks.
