Adding Audio Input and DV Camera Support

If you’ve worked through the sequence of steps outlined in the previous chapter, you’re now ready to extend the functionality of your QTKit capture player application.

In this chapter, you’ll add audio input capability to your capture application, as well as support for input from DV cameras other than your built-in or attached iSight camera. This is accomplished with only a dozen lines of Objective-C code, with error handling included.
