Chapter 11 - Clock Components
This chapter discusses clock components. Clock components provide timing information. In QuickTime, the Movie Toolbox is the primary client of clock components. Applications seldom call clock components directly. However, you may want to develop your own clock component for use by the Movie Toolbox. Therefore, this chapter focuses on what you must do to create a clock component.
Before learning about clock components, you must be familiar with QuickTime time bases. See the chapter "Movie Toolbox" in Inside Macintosh: QuickTime for a complete description of time bases and of the Movie Toolbox functions that support time bases.
- "About Clock Components" presents some general information about clock components.
- "Clock Components Reference" describes the constants, data structures, and functions that are specific to clock components.
- "Summary of Clock Components" provides summaries of the clock component constants, data structures, and functions in C and in Pascal.
