In Chapter 7, On Capturing Still Images with the iSight Camera, we examined the Image Kit component of the Quartz framework, which includes classes focused on providing support for capturing and displaying still images. In this chapter, we will examine another framework, Quicktime Kit. Specifically, we will examine Quicktime Kit Capture, which is a subset of the QTKit framework and includes classes focused on providing support for capturing movies.
In this chapter, we shall learn the following:
What is Quicktime Kit Capture and how does it work?
Previewing the video capture
Capturing a single frame as a still image
Previewing audio capture
Capturing a movie to disk
Capturing compressed movies to disk
