Linux – Ripping DVD’s To AVI’s At The Command Line

You can backup your DVD’s to AVI files for archival purposes in Linux by using mencoder at the command line. Mencoder is installed on most Linux distributions when you install mplayer. The command is:

$ /usr/bin/mencoder dvd://1 -ovc lavc --af volnorm=1 \
-alang en -oac mp3lame -lameopts cbr:preset=128 \
-lavcopts vbitrate=900:v4mv:vhq:vcodec=mpeg4 -vf \
pp=de,scale=480:-2 -nosub -o filename.avi

This will produce an AVI file around 600-700 MB in size using English for the language option. It will also perform volume normalization, and strip the subtiles from being displayed. The audio will also be sampled at a constant bit rate of 128kbit/s.
