Whatever I do with ffmpeg the line:

ffmpeg -i familyguy.avi -acodec mp3 -ar 44100 -f flv fg.flv

always ends in:

Unknown encoder ‘mp3′

I’ve tried uninstalling and installing various libs and such, manually and with apt. I don’t get it.

Doing ldd on the ffmpeg-bin I get:

This also didn’t work for me. The very first instruction needs expanding: don’t just uninstall ffmpeg but also uninstall libavcodec1d. Then the medibuntu versions can get installed, and now it works for me. (Well, it now shows lame in the ldd output now – I’ve not actually tried mp3 stuff yet.)

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.

Not working on Hardy here. Followed this step by step and no joy.

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.

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.
