Wired Movies and Sprites

Action Sprites Media Format Extensions

This section describes all of the atom types and IDs which are used to extend the sprite track's media format, enabling the new action sprite capabilities.

"Authoring Wired Movies and Sprite Animations," describes how to create basic sprite samples with images, sprites, and their properties. A complete description of the grammar for sprite media handler samples, including action sprite extensions, is included in "Sprite Media Handler Media Format Definition" .

There are also new sprite track property atoms. In particular, you must set the kSpriteTrackPropertyHasActions track property in order for your sprite actions to be executed.
