Detailed Description

Segmenter for LL-DASH profiles. Each segment constist of many fragments, and each fragment contains one chunk. A chunk is the smallest unit and is constructed of a single moof and mdat atom. A chunk is be generated for each recieved MediaSample. The generated chunks are written as they are created to files defined by MuxerOptions.segment_template if specified; otherwise, the chunks are appended to the main output file specified by MuxerOptions.output_file_name.

Member Function Documentation

GetIndexRange()

bool shaka::media::mp4::LowLatencySegmentSegmenter::GetIndexRange ( size_t *  offset, size_t *  size  )

overridevirtual

Returns

true if there is an index byte range, while setting offset and size; or false if index byte range does not apply.

Implements shaka::media::mp4::Segmenter.

GetInitRange()

bool shaka::media::mp4::LowLatencySegmentSegmenter::GetInitRange ( size_t *  offset, size_t *  size  )

overridevirtual

Returns

true if there is an initialization range, while setting offset and size; or false if initialization range does not apply.
