| SegmentIndexEntry Fields |
The SegmentIndexEntry type exposes the following members.
Fields| Name | Description | |
|---|---|---|
 | ReferencedSize | The distance in bytes from the first byte of the referenced box to the first byte of the next referenced box or in the case of the last entry, the first byte not indexed by this Segment Index Box. |
| ReferenceType | When set to 0 indicates that the reference is to a movie fragment (‘moof’) box; when set to 1 indicates that the reference is to a segment index (‘sidx’) box. |
| SAPDeltaTime |
Indicates TSAP of the first SAP, in decoding order, in the referenced subsegment for the
reference stream. If the referenced subsegments do not contain a SAP, SAP_delta_timeis
reserved with the value 0; otherwise SAP_delta_timeis the difference between the earliest
presentation time of the subsegment, and the TSAP (note that this difference may be zero,
in the case that the subsegment starts with a SAP).
|
| SAPType |
Indicates a SAP type as specified in TS26.247 [49], Annex G.6, or the value 0. Other type
values are reserved. For the detailed semantics of this field in combination with other
fields, see the table below.
|
| StartsWithSAP |
Indicates whether the referenced subsegments start with a SAP. For the detailed semantics
of this field in combination with other fields, see the table below.
|
| SubSegmentDuration |
When the reference is to Segment Index Box, this field carries the sum of the
subsegment_duration fields in that box; when the reference is to a subsegment, this field
carries the difference between the earliest presentation time of any sample of the
reference track in the next subsegment (or the first subsegment of the next segment, if
this is the last subsegment of the segment or the end composition time of the reference
track if this is the last subsegment of the representation) and the earliest presentation
time of any sample of the reference track in the referenced subsegment; the duration is
expressed in the timescale value in this box.
