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.
