Track Reference Entry Structure

A track reference array atom contains an array of track reference entry structures that specify information about any low-resolution image tracks contained in a movie. A track reference entry structure is defined by the VRTrackRefEntry data type:



 
typedef struct VRTrackRefEntry {

    UInt32                              trackRefType;

    UInt16                              trackResolution;

    UInt32                              trackRefIndex;

} VRTrackRefEntry;

trackRefType: The track reference type. See "Track Reference Types" for a description of the available track reference types.
trackResolution: The track resolution. See handlink "QuickTime VR Manager/Resolutions" for a description of the values that can occur in this field.
trackRefIndex: The index of the track reference.
