don't know what you included/didn't include in compiling but here's a
script that I have used for converting DVD's into files to put on my
iPod...
#!/bin/sh
#
BASE="/home/craig/dw"
IN="in-mp4"
OUT="out-mp4"
TITLE="1"
NAME="HARD_DAYS_NIGHT-"
CHAPTERS="15"
X="1"
#
# First, let's rip the DVD into individual files
#
while [ $X -ne $(( $CHAPTERS + 1)) ]
do
if [ $X -lt 10 ]; then
TRNO="0$X"
else
TRNO=$X
fi
START=$X
STOP=$(( $X + 1 ))
# mplayer dvd://$TITLE -chapter "$X-$X" -dumpstream -dumpfile
"$TRNO-$NAME.vob"
mplayer dvd:// -chapter "$X-$CHAPTERS" -dumpstream -dumpfile
"$TRNO-$NAME.vob"
X=$(( $X + 1 ))
done
#
# Now, let's convert them into iPod MP4 format
#
X="1"
#
while [ $X -ne $(( $CHAPTERS + 1 )) ]
do
if [ $X -lt 10 ]; then
TRNO="0$X"
else
TRNO=$X
fi
START=$X
STOP=$(( $X + 1 ))
ffmpeg -i "$TRNO-$NAME.vob" \
-aspect 4:3 \
-s 320x240 \
-acodec aac \
-ab 128 \
"$TRNO-$NAME.mp4"
mv "$TRNO-$NAME.vob" $IN/
mv "$TRNO-$NAME.mp4" $OUT/
X=$(( $X + 1 ))
done
