public class SampleGroupDescriptionBox extends AbstractFullBox
This description table gives information about the characteristics of sample groups. The descriptive information is any other information needed to define or characterize the sample group.
There may be multiple instances of this box if there is more than one sample grouping for the samples in a track. Each instance of the SampleGroupDescription box has a type code that distinguishes different sample groupings. Within a track, there shall be at most one instance of this box with a particular grouping type. The associated SampleToGroup shall indicate the same value for the grouping type.
The information is stored in the sample group description box after the entry-count. An abstract entry type is defined and sample groupings shall define derived types to represent the description of each sample group. For video tracks, an abstract VisualSampleGroupEntry is used with similar types for audio and hint tracks.
