First You need to enable RPM fusion repositories. This can be done by

sudo yum localinstall –nogpgcheck

sudo yum localinstall –nogpgcheck

or manually install from

& download rpm link are given below

If any missing gpg key error come like this:

GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-18-x86_64

GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-18-x86_64

Goto below site :

& download gpg key

Copy the same to /etc/pki/rpm-gpg/ & rename to key name as shown in error.[Need root privilege to copy files]

In case you are installing i386, please rename the file name accordingly.

If fedora 18 beta installed, then install ‘gstreamer1’ is required instead of gstreamer. So search & install gstreamer1 codec

sudo yum install gstreamer1 gstreamer1-plugins-good gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly

Same step, but install following for fedora 17 :

sudo yum install gstreamer gstreamer-plugins-good gstreamer-plugins-bad gstreamer-plugins-ugly gstreamer-ffmpeg libdvdread libdvdnav lsdvd

Alternatively, you can also install and use vlc or smplayer to view mkv videos–both can decode H.264

sudo yum install vlc

sudo yum install smplayer

Note: The new totem 3.6 uses gstreamer 1.0 & there is no gstreamer1-ffmpeg package  in repository. So you have to use vlc or smplayer till package comes.

Update : Install gstreamer1-libav for ffmpeg packages.
