Was your vobcopy line $vobcopy -i /path/to/mountpoint -n ${TITLE_NO} |
39 |
-l -O ${MOVIE}_${TITLENO}.vob ? |

My ffmpeg lines for dvd to mkv: |
42 |
|
43 |
2.0 audio: |
44 |
for a in 1 2; do schedtool -B -e nice ffmpeg -threads 4 -i $file.vob |
45 |
-pass $a -vcodec libx264 -b 800k -deinterlace -acodec libfaac -ac 2 |
46 |
-ab 192k -y $file.mkv ;done |
47 |
|
48 |
5.1: |
49 |
for a in 1 2; do schedtool -B -e nice ffmpeg -threads 4 -i $1.vob |
50 |
-pass $a -vcodec libx264 -x264opts preset=slower -b 800k -deinterlace |
51 |
-acodec libfaac -ac 6 -ab 440k -y $1.mkv ;done |
52 |
|
53 |
I use schedtool and nice to keep ffmpeg from hogging the cpu. |

Downscale hd to 480p and de-interlace DVDs and other 480i content. |
63 |
720x480 will look pretty good on a 1024x600 (WSVGA) screen. |
