mpegdemux

Introduction

mpegdemux is an MPEG1/MPEG2 system stream demultiplexer. It can be used to list the contents of an MPEG system stream and to extract elementary streams.

mpegdemux has four primary modes of operation:

scan

In this mode the MPEG system stream is scanned for elementary streams. The first packet of each elementary stream is reported.

list

In this mode the contents of an MPEG system stream are listed in a textual form. This is useful to get an overview of what's in an MPEG file.

demux

In this mode elementary streams are extracted from an MPEG system stream. The system stream packet structure is dissolved in the process. Typically each extracted stream is written to its own file.

remux

This is like demux, except that the MPEG system stream structure is left intact. This means that the output is again an MPEG system stream with all but the selected elementary streams removed.

Examples

List the elementary streams in an MPEG system stream:

$ mpegdemux -c src.mpg

List all the packets contained in an MPEG system stream:

$ mpegdemux -l -k -s all -p all src.mpg

Extract the first video stream:

$ mpegdemux -d -s 0xe0 src.mpg dst.m1v

Extract all audio streams:

$ mpegdemux -d -s 0xc0-0xdf -b audio_##.mpa src.mpg

Remove the second video stream:

$ mpegdemux -r -s all/-0xc1 -p all src.mpg dst.mpg
