public class SampleToChunkBox
extends AbstractFullBox

4cc = ""stsc""

Samples within the media data are grouped into chunks. Chunks can be of different sizes, and the samples within a chunk can have different sizes. This table can be used to find the chunk that contains a sample, its position, and the associated sample description. Defined in ISO/IEC 14496-12.
