I guess your DVD-Film is concatenated of the files:
for i in {1..5}
do
echo "file 'VTS_01_i.VOB'";
done
right? in this case you have to extract the whole concatenated VOB with
mplayer and dump it into a file before you can apply ffmpeg
[code]
mplayer dvd://TITLE -dumpstream -dumpfile ~/media/movie.vob # be sure to
select the correct TITLE - in this case it would be 1
ffmpeg -i ~/media/movie.vob -g 25 -keyint_min 3 -vf
"crop=x=14:out_w=in_w-32:y=76:out_h=in_h-152" -aspect "16:9" -map 0:v
-c:v libx264 -map 0:a -c:a copy OUTPUTFILE.mkv # apply ffmpeg
[/code]
mplayer can extract subtitles as well as much as I know. Let us know how
you've done it, after you manage it....
