### avvideowall ###

===========================================================================

DESCRIPTION:

avvideowall is a command line application that creates a wall of video out 

of the video capture devices on your Mac.

avvideowall demonstrates the flexibility of AV Foundation capture on Lion. 

It is a command line application that creates a wall of 

AVCaptureVideoPreviewLayers, 4 per capture device in a mirrored square, and 

sends them flying around the screen.  The sample demonstrates how to create 

a complex AVCaptureSession consisting of multiple AVCaptureVideoDeviceInputs 

and multiple AVCaptureVideoPreviewLayers, and how to connect the correct 

inputs to the desired layers.

This sample does not use Automatic Reference Counting. To build, disable ARC

in the Xcode project's Build Settings.

Usage: press space to spin/reset the video preview layers; press q/Q to quit
