I've installed GStreamer plugins for Fedora 14 using yum. However, when running a qt-phonon application with the GStreamer backend, I get the error

Warning: You do not seem to have the base GStreamer plugins installed. All audio and video support has been disabled

Is 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?

gst-inspect maybe? Should let you know which plugins are installs. –  derobert Oct 1 '12 at 21:42
Hmm gst-inspect is showing I have valid plugins. I guess the better question is why am I getting that warning? –  IslandCow Oct 1 '12 at 21:49
@IslandCow - As derobert said, you can use gst-inspect-0.10 -a | grep gst-plugins-base to list the base plugins installed on your system. I'm not familiar with yum but rpm -ql nameofpackage should list all files in that package (with their full path) provided you know the exact name of the gstreamer-base-plugins package. If gstreamer-base plugins are present on your system then it is a Phonon problem and you'll have to find out why it doesn't detect them. –  don_crissti Oct 1 '12 at 21:51
@derobert thanks for that. grepping for gst-plugins-base only yields uridecodebin and decodebin2. I know that's not right ... It also throws GStreamer-Critical GST_IS_ELEMENT failed :( –  IslandCow Oct 1 '12 at 22:06

Install RPM Fusion repos

Then install phonon's vlc backend:

su -c 'yum install phonon-backend-vlc'

Remove the gstreamer backend:

su -c 'yum erase phonon-backend-gstreamer'

I have the Xine backend working but I want to use the gstreamer backend. I'm testing an application that runs on an embedded product that doesn't have vlc. –  IslandCow Oct 1 '12 at 20:27
