Sprite Media Handler

This chapter discusses the sprite media handler, which you can use to add a sprite animation track to a QuickTime movie. It makes use of the functionality provided by the sprite toolbox discussed in “Chapter 2, QuickTime Sprites, Sprite Animation and Wired Movies,” and provides routines for manipulating the sprites and images in a sprite track. If you are using the sprite media handler, you don’t need to use the toolbox API.

The chapter is divided into the following major sections:

• “Defining the Sprite Media Handler” discusses the sprite media handler, which provides routines for manipulating the sprites and images in a sprite track.

• “Using Sprites in a Sprite Track” describes some of the ways your application can use sprites in QuickTime sprite tracks, including sprite button behaviors and variable string support.

• “Creating a QuickTime Sprite Movie” discusses sample code that you can use to create a sprite movie containing one sprite track.

• “Useful Sprite Media Handler Functions” describes the sprite media handler functions available to your application. For example, you use the SpriteMediaSetSpriteProperty function to set the specified property of a sprite.

• “Wired Actions in QuickTime” describes the new wired actions and operands introduced in QuickTime 5.01.
