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.
