I have a Gateway T-6321 that I recently had to re-install Fedora Linux v17 on. I've put just about everything that was on there from before (Totem, Clementine...Thunderbird etc.) but when I try to play movies in Totem or music in Clementine I get errors such as:

Clementine: - "Your GStreamer installation is missing a plugin."

Totem: - "A program requires additional plugins to decode this file:

              The following plugins are required:
                H.264 decoder
                MPEG-4 AAC decoder

              Do you want to search for these now?

My problem is when it searches for these it tells me they're already installed? What is the solution for this kind of error? is there a file I need? or a missing piece of this puzzle?


Try installing these. You may have to install repository files for rpmfusion which you can easily get from the net from their site.

Some of the packs  mentioned may already be installed. Yum will simply skip them. Some I may have posted more than once, so excuse that.

These are meta packs which pull in lots of decoders, plugins etc.

You can also install these packs for multimedia.

mozilla-vlc  vlc-plugin-jack vlc-extras vlc ffmpeg2dirac ffmpeg2theora dirac mp3gain 
libtunepimp-extras-freeworld 

Install flash-plugin from adobe.

Some packs may be redundant but they are small & also don't hurt anyone.
