First, yes, AVFoundation is the way to go.
Second, you can use AVCaptureView or AVCaptureVideoPreviewLayer. II
recommend that you don¹t subclass AVCaptureVideoPreviewLayer, but rather
embed it in your own custom CALayer. That gives you more freedom of control,
and if you want to do things like clipping and add shadows, you can do it.
Otherwise the capture layer will clip the shadows.
Our (still unreleased) application allows any number of cameras to be used
simultaneously, with individual display parameters. You can even (installing
their driver) use a $5 app, PocketCam, as a wireless remote video camera
input.
