I'm supposed to be studying - but looks like this post : http://symbiotix.net/articles/compiling-ffmpeg-mp3-ubuntu-revised-ubuntu-gutsy-server is what I need. I'll give it a try when I have time - or maybe medibuntu has a ffmpeg with it build in?
Stolen from his site:
"However, we’re using Ubuntu based servers and Ubuntu has a strict policy not to include non-free software. This means that the ffmpeg version in the repositories is not built with essential functionality, like mp3 support for audio conversion.
Solution: compile from source. Don’t run away screaming. It’s real easy.
1. enable universe and multiverse repositories
UbuntuGuide » general notes » how to add extra repositories
2. get your tools
sudo apt-get install checkinstall build-essential subversion
3. get the latest ffmpeg sources
cd /usr/local/src sudo svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
4. get the necessary dependencies
sudo apt-get install liblame-dev libfaad-dev libfaac-dev libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev
5. configure
cd ffmpeg sudo ./configure --enable-gpl --enable-liba52 --disable-debug --enable-libmp3lame --enable-libfaad --enable-libfaac --enable-pthreads --disable-vhook
6. compile
sudo make
7. go have a snack
8. create the .deb package
sudo checkinstall
note: just press [return] each time when asked for a configuration option
9. install the .deb package
sudo dpkg -i [ffmpeg_your_version.deb]
10. rejoice "
