// Segmenter for MP4 Dash Video-On-Demand profile. A single MP4 file with a
|
|
// single segment is created, i.e. with only one SIDX box. The generated media
|
|
// file could contain one to many subsegments with subsegment duration
|
|
// defined by|MuxerOptions.segment_duration|. A subsegment could contain one
|
|
// to many fragments with fragment duration defined by
|
|
// |MuxerOptions.fragment_duration|. The actual subsegment or fragment duration
|
|
// may not match the defined duration exactly but in a best effort basic, i.e.
|
|
// the segmenter tries to end subsegment/fragment at the first sample with
|
|
// overall subsegment/fragment duration not smaller than defined duration and
|
|
// yet meet SAP requirements. VOD segmenter ignores
|
|
// |MuxerOptions.num_subsegments_per_sidx|.
