Vamps was written to make cheap backups of DVDs under Linux. Back in
|
|
2003 Metakine published the source code of their M2Requantiser module.
|
|
The idea was to make use of this great piece of software to create a
|
|
transcoder for Linux for shrinking the content of a DVD9. This would
|
|
enable backups on cheap single layer DVDRs (double layer burners weren't
|
|
even available that time). The Metakine requantizer is pretty fast and
|
|
so Vamps was designed not to break this outstanding performance.
|
|
|
|
Vamps builds a wrapper around the requantizer to extract the elementary
|
|
MPEG2 video stream from the DVD's program stream, feed it through the
|
|
requantizer and finally re-pack it into the program stream again.
|
|
Besides this, Vamps allows to select audio and subtitle streams that
|
|
should be copied into the output stream. This gives another small gain
|
|
of disk space, since unwanted streams may be discarded.
|
|
|
|
Summed up, Vamps is only a very basic, but nevertheless essential tool
|
|
to transcode DVD videos to a smaller size. Vamps does not need to write
|
|
temporary data files, which is a major pro. Vamps is very fast. The
|
|
downside is, that Vamps is not capable to make DVD backups on its own.
