The Sub-Sample Information Box is designed to contain sub-sample information.
A sub-sample is a contiguous range of bytes of a sample. The specific definition of a sub-sample shall be supplied for a given coding system (e.g. for ISO/IEC 14496-10, Advanced Video Coding). In the absence of such a specific definition, this box shall not be applied to samples using that coding system.
If subsample_count is 0 for any entry, then those samples have no subsample information and no array follows. The table is sparsely coded; the table identifies which samples have sub-sample structure by recording the difference in sample-number between each entry. The first entry in the table records the sample number of the first sample having sub-sample information.
Note: It is possible to combine subsamplePriority and discardable such that when subsamplePriority is smaller than a certain value, discardable is set to
