Extract audio from .avi file on Kubuntu and finding which package a file in

Submitted by augustin on Sat, 2010-01-02 18:23

To extract the audio from an .avi video file, use the command:

mplayer video.avi -vc dummy -vo null -af resample=44100 -ao pcm:file=ripped-audio.wav

Make sure that the program oggenc is installed. I didn't know which package this program was, so I searched and found this nifty tool for Ubuntu: apt-file

Install it and update its internal database:

# apt-get install apt-file
# apt-file update

Then using this tool to search for oggenc told me I could find it in the vorbis-tools package:

$ apt-file search oggenc
vorbis-tools: /usr/bin/oggenc

I installed the package easily:

sudo apt-get install vorbis-tools

Then you can compress the .wav file with the following command:

oggenc -q4 ripped-audio.wav -o ripped-audio.ogg

That's it!

I have also documented this in the overshoot wiki: extract audio from .avi file.
