Hello all,
Following a more or less recent thread, I started to extract audio
from youtube videos, to listen in the car. Neat. Now, I have a few
concert DVDs which would be nice to listen to while driving. Anyone got
a 'recipe' command line to extract the audio out of a DVD and possibly,
to extract only certain songs ?
Thanks !

Hello!
I always use mplayer for that:
mplayer -vo null -dumpaudio -dumpfile output.mp3 intput.vob
works like a treat. Maybe you could even use mencoder or ppossibly the
ffmpeg utility or whatever it was they suggested at the time for extracting
audi from youtube.
If you want a different format than mp3, something like this might do the
trick:
mplayer -ao pcm:file=tmp.wav -vo null input.vob
And then encode the tmp.wav to whatever you like. It's also easily
scriptable.
You will only get seperate songs out of that, if they are stored in seperate
.vob-files.
I have written a script to trim recordings from radio. With a slight
adjustment that script will work for videos as well. It relies on you
listening to / skipping through the input and marking times. It uses ecasound
to do the trimming.
Hope that helps.
ciao

Here's the relevant part of a script I've been using to do this. It's
nothing fancy but it works, it just dumps the audio as numbered wav
files (one file for each chapter). With a bit more creative scripting
you could automatically set the variables at the start by pulling them
out of lsdvd's output, but I'll leave that as an exercise for the
curious reader (i.e. I am lazy).
#!/bin/bash
#set these to match the dvd you want to rip
#use lsdvd to figure out which title and how many chapters you need
dvdpath=/dev/sr0
title=1
number_of_chapters=18
songnumber=1
while [ $songnumber -le $number_of_chapters ]; do
mplayer dvd://$title -chapter $songnumber-$songnumber -dvd-device
$dvdpath -vo null -vc dummy -ao pcm:file=$songnumber.wav
let songnumber=songnumber+1;
done

Hello Chris!
Ha, I never really delved into the dvd options of mplayer, not having many
DVDs at all. :-) But tht script is clever. Indeed get some awk/sed magic and
yo can completely automate it.
Thanks for sharing this!
Warm regards
Julien

This works OK. It would be nice to be able to do some adjustments on
the EQ and such. Is it possible to make the output go through Jamin
before the file is written to disk ? When using 'mplayer -ao jack
[...]' the Jamin VU meters all activate to the music, but there's no
sound output seen by mudita24, even though the Jamin outputs are
connected to playbacks 1 and 2 (using qjackctl). Actually, there's no
output when mplayer outs are directly connected to the playbacks. I
tried with vlc, and vlc works through jack but the problem is that vlc
is not listed in qjackctl's connections table which makes it impossible
to route through Jamin.
At this point I presume that if the player's output has to go through
Jamin for EQ, then another device would be doing the recording of
Jamin's output. Eq. it would not be possible to go out of the player
and then back into it for it to write the audio to disk (like a send
function maybe).

Hello!
As far as I am aware, Mplayer has no such send-function. If you know, what
EQ adjustments you want to make, you could include an equaliser in Mplayer,
since it is able to understand LADSPA plugns. Otherwise, you could also use
Ecasound, which is scriptable as well. Or latch on the suggesti9on made
earlier, by using a preconfigured session/mix with non-mixer. But the correct
mplayer ports connected to Jamin and Jamin connected to something else should
also give you the audio. You might use jack_capture or similar tools to record
from there. disadvantage is, that this would only work in realtime, i.e. take
a long time to process a whole DVD.
Warm regards
