wget http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm
sudo rpm -Uhv rpmfusion-free-release-6-1.noarch.rpm
wget http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm
sudo rpm -Uhv rpmfusion-nonfree-release-6-1.noarch.rpm
sudo yum install ffmpeg
