Sprite Track Formats

The following constants represent formats of a sprite track. The value of the constant indicates how override samples in a sprite track should be interpreted. You set a sprite track's format by creating a kSpriteTrackPropertySampleFormat atom.



 
enum {

    kKeyFrameAndSingleOverride      = 1L << 1,

    kKeyFrameAndAllOverrides        = 1L << 2

};

Constant descriptions

kKeyFrameAndSingleOverride: The current state of the sprite track is defined by the most recent key frame sample and the current override sample. This is the default format.
kKeyFrameAndAllOverrides: The current state of the sprite track is defined by the most recent key frame sample and all subsequent override samples up to and including the current override sample.
