QuickTime VR sample description ('qtvr')
Describe QuickTime VR samples.
Overview
Whereas the QuickTime VR media sample is simply the node information itself, all sample descriptions are required by QuickTime to have a certain structure for the first several bytes. The structure for the QuickTime VR sample description is as follows:
typedef struct QTVRSampleDescription {
UInt32 size;
UInt32 type;
UInt32 reserved1;
UInt16 reserved2;
UInt16 dataRefIndex;
UInt32 data;
} QTVRSampleDescription, *QTVRSampleDescriptionPtr, **QTVRSampleDescriptionHandle;
