If you already have ffmpeg installed (without mp3 support), then firstly uninstall it.
MP3 support isn’t included with ffmpeg in the default Ubuntu repositories so to get it you have to enable the Medibuntu repos (assuming this is legal in your area).
sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.list wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O - | sudo apt-key add - && sudo apt-get update
Then you can install ffmpeg and the libmp3lame codec (part of the libavcodec package)
sudo apt-get install ffmpeg sudo apt-get install libavcodec1d
You can verify the dependencies of ffmpeg with ldd

It should then let you encode videos with mp3 audio…
ffmpeg -i jonathan-davis-news24-2008-01-22.avi -f flv -s 400s220 -acodec mp3 -ar 44100 jd.flv
libavcodec1d was what i was missing – installing it allowed me to output mp3 audio on transcoded videos
thankyou for this. most of the other how-tos involve recompiling ffmpeg and that seemed like total overkill.
ubuntu 8.04 NOT WORK !!!
Output #0, flv, to ‘3_0.flv’:
Stream #0.0: Video: flv, yuv420p, 180×144, q=2-31, 200 kb/s, 25.00 fps(c)
Stream #0.1: Audio: 0×0000, 44100 Hz, stereo, 64 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
Unsupported codec for output stream #0.1
It works in Ubuntu 8.04, but you have to force-install the Medibuntu versions of both ffmpeg and libavcodec1d – I used synaptic to achieve this.
Not working on Hardy here. Followed this step by step and no joy.
You have to make sure you install the medibuntu version of ffmpeg and libavcodec1d, or you won’t get the support for mp3 encoding.
ldd /usr/bin/ffmpeg will show you the dependencies of your ffmpeg, i think the ubuntu repo version doesn’t include ‘libmp3lame.so.0′ and some other modules.
