• Get chapter information

dvdxchap -t 1 /dev/sr0 > chapters.txt

• Get subtitles

mencoder dvd://1//dev/sr0 -nosound -ovc frameno -o /dev/null -slang en -vobsubout sub.en

• Convert subtitles to srt: Use avidemux, works fine.

• Get the crop values:

mplayer dvd://1//dev/sr0 -vf cropdetect -sb 50000000

• Write the values down. Ex: -vf crop=704:560:12:6
• Do a small mencoder test to get the correct aspect ratio after cropping:

mencoder dvd://1//dev/sr0 -vf crop=704:560:12:6 -oac copy -ovc raw -endpos 120 -o movie-cropped.mpg
mplayer -v movie-cropped.mpg | grep -i aspect

• Example: 1.79:1

• Encoding first pass:

mencoder -nosub dvd://1//dev/sr0 -vf pullup,softskip,crop=704:560:12:6,harddup -nosound  -ovc x264 -x264encopts bitrate=1300:subq=5:bframes=3:b_pyramid=normal:turbo=1:pass=1 -of rawvideo -o movie.264

• Enconding second pass:

mencoder -nosub dvd://1//dev/sr0 -vf pullup,softskip,crop=704:560:12:6,harddup -nosound -ovc x264 -x264encopts bitrate=1100:subq=5:8x8dct:frameref=2:bframes=3:b_pyramid=normal:weight_b:pass=2 -of rawvideo -o movie.264

• Get audio

mkfifo audiodump.pcm
mplayer dvd://1//dev/sr0 -aid 129 -ao pcm:fast:nowaveheader -channels 6 & faac -b 256 -q 100 -P -R 48000 -C 6 -X audiodump.pcm -o audio129.aac
rm audiodump.pcm

• Use mmg to merge audio129.aac, movie.264, sub.en.idx, sub.en.srt

• The correct mapping for a 4 channel sound card it's given by: (This adds the center channel to the two front channels

mplayer-mt -channels 6 -af pan=6:0.3333:0:0:0:0:0:0:0.3333:0:0:0:0:0:0:0.5:0:0:0:0:0:0:0.5:0:0:0.3333:0.3333:0:0:0:0:0.3333:0.3333:0.5:0.5:0:0 audio129.aac
