3. Examples
-----------
Here's a *very* brief example of how you could use mkvmerge
with mencoder in order to rip a DVD:
1. Extract the audio to PCM audio:
mplayer -ao pcm:file=audio.wav -vo null -vc dummy dvd://1
2. Normalize the sound (optional)
normalize audio.wav
3. Encode the audio to Vorbis:
oggenc -q3 -oaudio-q3.ogg audio.wav
4. Somehow calculate the bitrate for your video. Use something like:
```
video_size = (target_size - audio-size) / 1.005
video_bitrate = video_size / length / 1024 * 8
```
- `target_size`, `audio_size` in bytes
- `length` in seconds
- 1.005 is the overhead caused by putting the streams into an Matroska file
(about 0.5%, that's correct ;)).
- `video_bitrate` will be in kbit/s
5. Use the two-pass encoding for the video:
mencoder -oac copy -ovc lavc \
-lavcopts vcodec=mpeg4:vbitrate=1000:vhq:vqmin=2:vpass=1 \
-vf scale=....,crop=..... \
-o /dev/null dvd://1
mencoder -oac copy -ovc lavc \
-lavcopts vcodec=mpeg4:vbitrate=1000:vhq:vqmin=2:vpass=2 \
-vf scale=....,crop=..... \
-o movie.avi dvd://1
6. Merge:
mkvmerge -o movie.mkv -A movie.avi audio-q3.ogg
`-A` is necessary in order to avoid copying the raw PCM (or MP3) audio as well.
