I've installed GStreamer plugins for Fedora 14 using yum.  However, when running a qt-phonon application with the GStreamer backend, I get the errorWarning: You do not seem to have the base GStreamer plugins installed.            All audio and video support has been disabledIs there a good baseline test to determine if this is a Phonon problem?  Does anybody know where yum installs the GStreamer plugins and how GStreamer resolves plugins?
How can you tell if GStreamer plugins are installed correctly
