Hi,
Good day!
**Check your current driver version by going into the device manager.**For most versions of Windows, that’s in the Control Panel (classic), System, and Device Manager). While you may not think it’ll make a difference, the latest version of the driver for your particular webcam could include updates that handle some of the methods that Skype software uses to access your webcam video stream. In particular, if you’re having problems with Skype having no video, you’ll want to make sure that your device supports at least DirectShow 9.1 standard. Check with the manufacturer website of your webcam for the latest driver update, and of course doing a Windows update. Download and install the latest version of Skype.
Moreover, make sure other programs aren’t using your webcam. There could be other applications running in the background that could be capturing the data stream from the webcam already. Try closing down all of your windows, especially any other IM and other Internet applications, and then restart Skype again.
On the Skype app> go to Tools> Options > Video settings. If you can see yourself, you're all set! By the way, based on your post description, you're using Windows RT. If so, please check this FAQ.
