vcdmplex -- Multiplex MPEG audio/video streams into one MPEG system stream
SYNOPSIS
vcdmplex video_stream audio_stream system_stream
DESCRIPTION
This manual page documents briefly the
vcdmplex command.
This manual page was written for the Debian GNU/Linux distribution
because the original program does not have a manual page.
vcdmplex is a program that multiplexes seperate
MPEG audio and video streams into one MPEG system stream, suitable for
use with mkvcdfs.
OPTIONS
"video_stream"
Filename of the input MPEG video stream
"audio_stream"
Filename of the input MPEG audio stream
"system_stream"
Filename to output the MPEG system stream to
NOTES
"
vcdmplex should be able to multiplex any MPEG video and audio streams,
not just VCD compliant streams. It can be used even for MPEG-2 video
streams, I don't know if the output adheres to any standard, however.
"
Messages in the form: "Inserted padding sector ..." are normal when
multiplexing VCD compliant streams, they just tell you that your actual
bitrate is slightly below VCD bitrate.
"
Messages: "***** BUFFER underrun - output may not play correctly *****"
are more severe, they come if the actual bitrate of your MPEG stream is
higher than the one specified in the header. The resulting system stream
might be unplayable!
"
If video and audio stream bitrates comply exactly with the VCD
specification (1152 KBit/s or 224 KBit/s respectivly), exactly 75
sectors/second are generated and the system stream is stuffed with
padding sectors as needed. Otherwise no padding sectors are created.
