True.
There is no QCamera class in Qt.

QCamera is meant to be used on mobile phones (unless I'm wrong)

You find a library that can do that.
I guess my first look would be GStreamer or similar

Maybe they have written code to access camera on the platforms they are compatible with.

may be the ui and networking is done using Qt.. are you sure skype uses Qt for camera ? since skype has video calls long before Qt introduced camera in mobility , isnt it ?

Read my last post again, and have a look at the link.
It will tell you where QCamera comes from.

Skype supports video input through native API such as V4L on Linux.
