howto rip dvd with subtitles to matroska container using `mplayer`, `mencoder`, `ffmpeg`, `MP4Box` and `mkvmerge`.


# get data

## get movie and audio

    mplayer dvd://1 -dvd-device /dev/cdrom -v -dumpstream -dumpfile original.vob

## get subtitles

    #mplayer dvd:// -dvd-device /dev/cdrom -v -vo null -ao null | grep "subtitle"
    mencoder dvd://1 -dvd-device /dev/cdrom -nosound -ovc frameno -o /dev/null -slang de -vobsubout original


# extracting / encoding

## one pass

### audio, f.e. ac3 aka dolby digital audio

    ffmpeg -i original.vob -codec:a ac3 video.ac3

### audio, f.e. aac

    ffmpeg -i original.vob -r 23.976 -ac 2 -vn -f wav -y - | faac -q 90 - -o video.aac

### video

    ffmpeg -i original.vob -an -codec:v libx264 video.h264


## two pass

### not working, i think...

    ffmpeg -i title.vob -pass 1 -an -codec:v libx264 -passlogfile bluray-movie.log -f rawvideo /dev/null
    # constant rate-factor is incompatible with 2pass.
    ffmpeg -i title.vob -pass 2 -an -codec:v libx264 -passlogfile bluray-movie.log bluray-movie.h264
    ffmpeg -i title.vob -codec:a pcm_s24le bluray-movie.wav


# muxing

## mp4

    MP4Box -add title.h264#video -add title.ac3#audio -fps 23.976 bluray-movie.ac3.mp4

## mkv

    mkvmerge -o video.h264.aac.mkv video.h264 video.aac original.idx
