[SOLVED] [vlc] Save audio as mp3

gregors · 11-10-2021, 10:24 PM

Hi there!

I have an very old mp3 player (Archos, 4GB) which I like to use to listen to audio books. Now I want to use this player to listen to movies I have already seen. With xine and lame this is no problem - it just can take hours because xine only saves its audio output when playing at normal (1x) speed.

VLC can do this a lot faster. But the documents I found don't help me with achieving this task on the command line. Using the GUI is a torture (imagine saving the audio tracks of a TV serial, having to wait 30 to 45 minutes for every episode to finish).

Is there anyone around who has done this with VLC? It seems the VLC docs aren't very helpful when it comes to scripting (or I didn't find the right docs).

TIA

Gregor

PS: This is how I do it using xine and lame:

Code:

DESTFILE=`basename $1 | cut -d. -f1`
echo "Zieldatei:  $DESTFILE.mp3"

xine $1 --auto-play=q -A file
lame --preset standard xine-out.wav $DESTFILE.mp3; rm xine-out.wav

PPS: ffmpeg does it:

Code:

/usr/bin/ffmpeg -i /home/gszaktilla/dokumente/platz/s04e01.mp4 -c:a mp3 s04e01.mp3

It appears you already have your movies ripped to mp4. vlc is just going to use ffmpeg under the hood to extract the audio from your mp4 movie file so I don't think you will get much speed improvement switching to vlc from ffmpeg and ffmpeg is clearly scriptable. You can also open the mp4 file in audacity and export the audio as mp3 or any other audio format you desire. As for using vlc from the command line, check this out:

Well, I'm not just referring to mp4 movies, this was just an example.
