Problem with s:VideoDisplay component

Hello everybody.

I’m working in a videoconference system with Flex 4.

My problem is in the s:VideoDisplay component

I declare it as follows:

<s:VideoDisplay id="localVideoDisplay" width="320" height="240"/>

And then I attach my webcam:

var camera:Camera = Camera.getCamera(“mycamera”);

localVideoDisplay.attachCamera(camera);

All works properly but when I try to disconnect de cam by using:

localVideoDisplay.attachCamera(null);

It doesn’t work. However, this method works perfectly with the mx:VideoDisplay component.

Does anybody knows how can I do this in a s:VideoDisplay?

Thanks for your answers.

Regards.
