[MEncoder-users] DVD >> MKV with mencoder script.

[Federico 'Pain' Pistono]

I'm trying to crate a simple script that will allow me to backup a DVD at an 
acceptable quality into a single MKV file with ogg audio.
I do not wish to use mp3, since it has a low quality and it requires high 
bitrate.
I know that the vorbis is not yet supported since it's not stable, but I saw 
lots of good results from other rips, hence I wanted to give it a try.
I made the script, but I guess something's not quite right yet, could you 
give me some suggestions?

Thanks

Fede


#!/bin/bash
if test "$1" = "" -o "$2" = "" -o "$3" = "" -o "$4" = "" ; then
cat << EOF
`basename $0` (c) 2004 Federico 'Pain' Pistono

Usage: `basename $0` [dvd-device] [dvd title] [bitrate] [outputfile]
- dvd-device = your dvd-device. Either a on-the-fly copy (/dev//dvd)
or a local directory, created before with vobcopy
- dvd title = the title of the dvd using mencoder (e.g mencoder dvd://1, 
also multiple titles, like 2-6 = from 2 to 6)
- bitrate = the bitrate to use for the ffmpeg compression (DivX, Xvid) 
(best > 900, 1100 is fair enough.)
- output file = name of the output file (e.g. Matrix)

Exmaples files:

[bash]$: fppdvdmkv /dev/dvd 1 1100 Matrix
[bash]$: fppdvdmkv ~/dvd/Matrix/ 1 1100 Matrix

EOF
exit 1
