RPM Fusion Repository provides software that the Fedora Project
or Red Hat doesn't want to ship.
You will find software like VLC media player, Mencoder FFmpeg
and other software that is not available in the stock Fedora or
Red hat repositories.
to install the RPM Fusion repository on your system simply type
rpm -ivh http://download1.rpmfusion.org/free/fedora/
then you can install software directly ie
yum install vlc
