cat << EOF
$this is a shell script to rip DVD and encode to DIVX
It can :
- rip, encode audio, encode video, separately into different sessions
- crop the black bars with autodetection
- choose the best resolution for the 16:9 or 4:3 format
- maximize volume (with a mencoder patch)
- extract subtitle into a separated text file (with transcode tools)
- split the AVI
The video bitrate is a bit different from the mencoder recommendation, it's
for a maximum filling for one CD, or to leave a margin to split the AVI.
Usage: $this [options]
Options:
-A, --auto use automatic values
-a, --angle=N set angle
-B, --videobr=<4-24000000> set video bitrate
-b, --audiobr=<32-320> change audio bitrate for lame [$audiobr]
-C, --cdrsize=SIZE change the size of a CD [$cdrsize]
-c, --nocolors do not use colors
-D, --deinterlace use deinterlace filter
-d, --dir=DIR change directory [./]
-f, --sid=FILE|0-31 set subtitle file or sid
-g, --subgreylevels=LEVEL set subgrey levels [$subgreylevels]
-h, --help print this help message
-i, --dev=DEV change dvd device [/dev/dvd]
-l, --crop=CROP set crop (ex: 720:576:0:0)
-N, --nbcd=<1-2> set number of CD
-n, --normalize use normalize to maximize volume
-p, --ipod make an ipod video
-r, --res=XXX:YYY set resolution
-S, --split split AVI
-s, --subtitle extract text subtitle
-T, --chapter=N set chapter
-t, --title=N set title
-V, --vol=<0-10> change audio input gain for lame [$volume]
-w, --wav extract audio to wav file(s)
-- options passed to mencoder (ex: -- -ni)
