HTML5 Media Element Not Respecting Output Protection Level

$

Hi there,

I am having trouble performing a HDCP check by playing a 10 seconds video. My expectation is that the video would fail when I attempt to play on a machine that doesn't support Output Protection ( a VGA cable is connected to my laptop ) . But it's playing fine. The same piece of code works fine in Google Chrome ( Widevine ) , I have a keystatuseschange event which gives me keyStatuses with value " output-restricted " , to which I can listen and stop the player and say HDCP not supported.

In Internet Explorer 11 ( on windows 8.1 ) or EGDE ( Windows 10 ) for some reason keystatuseschange event is not firing at all even when the hardware doesn't support output protection.

How do we do this in IE 11 & Edge ? Is there a different event I need to listen to  ? This would be a really big help. Please advice.

Thanks a lot 

Kiran Chandran
