vcdmplex1
Multiplex mpeg audio/video streams into one mpeg system stream
Usage
vcdmplex video_stream
audio_stream
system_stream
Overview
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

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.
