// 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|.
