Extract DVD
From Maze's wiki
This describes how to convert a DVD to mkv using:
- x264 for video
- ac3 for audio
- any subtitles
Install the packages
apt-get install mencoder mplayer gpac mkvtoolnix
For using encrypted DVDs build and install libdvdcss from http://download.videolan.org/pub/libdvdcss/last
./configure --prefix=/usr make make install
First write the video stream to the harddrive so the next steps will go faster. Also remember the aid and sid for audio and subtitles.
cat /dev/dvd > <title>.iso
Now extract audio from the stream. Just use AC3.
mplayer <title>.iso -aid <aid> -dumpaudio -dumpfile <title>.ac3
Now extract the subtitles from the stream.
mencoder <title>.iso -ovc raw -o /dev/null -nosound -sid <sid> -vobsubout <title>
Detect the amount to crop. Keep it running till it is stable for a while
mplayer <title>.iso -vf cropdetect
Run the first pass on the video
mencoder -v <title>.iso -vf <cropvalues> -ovc x264 -x264encopts pass=1:bitrate=1000 -nosound -nosub -noautosub -of rawvideo -o <title>.264
Run the second pass on the video
mencoder -v <title>.iso -vf <cropvalues> -ovc x264 -x264encopts pass=2:bitrate=1000 -nosound -nosub -noautosub -of rawvideo -o <title>.264
Put the video in a MP4 container
MP4Box -add <title>.264 <title>.mp4
Combine everything in a mkv container
mkvmerge -o <title>.mkv <title>.ac3 <title>.idx <title>.mp4
