Clementine doesn't play mp3

I want to use Clementine on Opensuse 13.2.
But I’m facing with this error :

Your GStreamer installation is missing a plug-in.

Please guide me to fix this

Install gstreamer-0_10-fluendo-mp3, available in the standard non-oss repo.

You don’t need to add any repo for that, just open YaST->Software Management and search for it, or run:

sudo zypper in gstreamer-0_10-fluendo-mp3
