NAME
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.
