C H A P T E R 1 The QuickTime Kit API QTMovieView QTMovieView, a subclass of NSView, can be used to display and control QuickTime movies. A QTMovieView is typically used in combination with a QTMovie object, which supplies the movie being displayed. A QTMovieView also supports editing operations on the movie. The movie may be placed within an arbitrary bounding rectangle in the view’s coordinate system, and the remainder of the view can be filled with a fill color. The movie controller, if visible, can also be placed within an arbitrary bounding rectangle in the view’s coordinate system. QTTrack The QTTrack class represents a QuickTime track (of type Track). QTTrack objects are associated with QTMovie objects and support methods for getting and setting the track properties. If necessary, you can retrieve the track identifier associated with a QTTrack object by calling its quickTimeTrack: method. QTMedia The QTMedia class represents a QuickTime media (of type Media). QTMedia objects are associated with QTTrack objects and support methods for getting and setting the media properties. If necessary, you can retrieve the media identifier associated with a QTMedia object by calling its quickTimeMedia: method. QTDataReference A QTDataReference object is a representation of a QuickTime data reference, which is used to specify the location of a movie or its media data. You can create QTDataReference objects that refer to data stored in files accessed using filenames or URLs, or in memory accessed using handles, pointers, or NSData objects. QuickTime Kit Functions The QuickTime Kit framework provides a number of functions for working with QTTime and QTTimeRange structures. QTTime The QTTime structure defines the value and time scale of a time. Functions are available for creating a QTTime structure, getting and setting times, comparing QTTime structures, adding and subtracting times, and getting a description. 14 QuickTime Kit Functions 2005-11-09 | © 2004, 2005 Apple Computer, Inc.

C H A P T E R 1 The QuickTime Kit API QTTimeRange The QTTimeRange structure defines a range of time. It’s used, for instance, to specify the active segment of a movie or track. Functions are available for creating a QTTimeRange structure, querying time ranges, creating unions and intersections of time ranges, and getting a description.
