First you have to install the rpmfusion repositories (if not already installed):
Code:
rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
then just download and install the codecs using yum:
Code:
yum install gstreamer-plugins-ugly
