[FFmpeg-user] Rip DVD with ffmpeg

My prefered way to transcode my DVD is to rely on a first dump with mplayer
then the eventual transcoding with ffmpeg.
Mplayer summoned with this line to identify the tracks (the biggest being
the movie, most likely):
mplayer -nosound -dvd-device g: dvd:// -identify
Then ripping it:
mplayer -dvd-device g: -nocache dvdnav://3 -chapter 1-19 -dumpstream
the device is my dvd-drive, obviously I used Windows here, adjust to your
mounting point under Linux.
I get a dvd.vob file that I can then use with FFMPEG without any problem.
