It also contains Mencoder, which is a great tool for ripping dvds (among other things).
Fortunately, the pre-built binaries at this site worked beautifully.
After downloading and unzipping them, I moved the two binary files, mplayer and mencoder, into /opt/local/bin so they appear in the default command-line path.
Since Apple's built-in DRM-enforcing DVD player is set to startup when a DVD is inserted, I changed the default action in the System Preferences under Media Preferences to be "Ignore" for the "When you insert a video DVD" option.
Now, I can play any DVD track with mplayer in Terminal, like this:
mplayer dvd://[track number]
MPlayer also supports other playback options like subtitles, etc. (docs related to DVD playback are here).
Ripping a DVD track is more complex, but the docs have good examples to follow.
I wrote this shell script to simplify the process:
#!/bin/sh # source for mencoder options: # http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-vcd-dvd.html # (using 18.104.22.168. NTSC DVD example) if [ $# -eq 2 ] then mencoder dvd://$1 -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf \ -vf scale=720:480,harddup -srate 48000 -af lavcresample=48000 \ -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:\ keyint=18:vstrict=0:acodec=ac3:abitrate=192:aspect=16/9 -ofps 30000/1001 \ -o $2.mpg else echo "mencoder_dvd_rip.sh [dvd track number] [output filename]" fi
So to rip track 0 of a DVD (which is usually the main movie track), all I have to do is this in Terminal:
mencoder_dvd_rip.sh 0 movie
