Have you ever wanted to play a .mp3 file in Ubuntu, well due to legal issues, Ubuntu does not ship with the codecs. If you would like them, you will need to install the following. Open up the terminal
sudo apt-get install gstreamer0.10-ffmpeg
sudo apt-get install gstreamer0.10-fluendo-mp3
sudo apt-get install gstreamer0.10-gl
sudo apt-get install gstreamer0.10-plugins-bad
sudo apt-get install gstreamer0.10-plugins-bad-multiverse
sudo apt-get install gstreamer0.10-plugins-ugly
sudo apt-get install gstreamer0.10-plugins-ugly-multiverse
sudo apt-get install gstreamer0.8-lame
sudo apt-get install gstreamer0.8-mad
sudo apt-get install gstreamer0.8-misc
