segmenter

Documentation

Overview

segmenter segments a progressive mp4 file into init and media segments. The output is either single-track segments, or muxed multi-track segments. With the -lazy mode, mdat is read and written lazily. The lazy write is only for single-track segments, to provide a comparison with the multi-track implementation.

There should be at most one audio and one video track in the input. The output files will be named as init segments: <output>_a.mp4 and <output>_v.mp4 media segments: <output>_a_<n>.m4s and <output>_v_<n>.m4s where n >= 1 or init.mp4 and media_<n>.m4s

Codecs supported are AVC and HEVC for video and AAC and AC-3 for audio.

Usage of segmenter:

	segmenter [options] infile outfilePrefix

options:

	-d uint
			Required: segment duration (milliseconds). The segments will start at syncSamples with decoded time >= n*segDur
	-lazy
			Read/write mdat lazily
	-m    Output multiplexed segments
	-v    Verbose output
