How to set up a mirroring session between iOS 8 and Yosemite?

Question

In OS X Yosemite, the screen of an iOS 8 device can be mirrored on an OS X computer and saved as a media file. This can be done manually using QuickTime Player, but I want to do the same programmatically.

Reading documents, the iOS 8 device should be open as a webcam.

A call [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo]on my Mac returns NSArrayno items.

How to set up a mirroring session using iOS 8 and Yosemite? How to identify a capture device for a mirroring session?
