vcdxrip: Introduction

 
 1 Introduction
 **************
 
 Note in the guide, we use the term Video CD to mean some sort of Video
 Compact Disk.  There are various formats of Video Compact Disks, the
 oldest format of which is called "VCD" and is followed by a version
 number: 1.0, 1.1 or 2.0.  Hopefully it should also be clear by context
 whether we are referring to a class of Video Compact Disks or the
 specific older format called VCD _version-number_.
 
    'vcdxrip' can be used to extract or disassemble the contents of a CD
 or a on-disk CD (commonly referred to as "ripping").  So in a sense
 'vcdxrip' is the inverse of 'vcdxbuild'--if you use 'vcdxrip' followed
 by 'vcdxbuild' on the result and then use another 'vcdxrip', you should
 get exactly what you got the first time you used 'vcdxrip' (assuming
 everything is working correctly).
 
    But 'vcdxrip' can also disassemble pieces of a CD or CD disk image
 and can create an XML Video CD description file without extracting a
 single file located on the CD.
 
    You might use 'vcdxrip' as a step in re-mastering or re-authoring and
 existing CD, or it could be used to extract MPEGs from a CD or on-disk
 CD image file.
 
    Since Video CD's use the ISO-9660 format, another way to "extract" an
 MPEG or piece of a Video CD is simply to mount the CD and use file copy
 commands.  However this program will interpret the Video-CD specific
 files and output a corresponding XML description file.  So 'vcdxrip' is
 something similar to the program 'vcd-info'; however the latter gives
 more detailed, lower-level Video-CD specific information and does not
 output its results in XML.
