I just can't play any video or music with gmusicbrowser or Parole because "something has not been installed/loaded, something is missing, GStreamer can't play this music file" and so on .. What can I do ? Please help me ! Thnaks
You just need to install the appropriate gstreamer plugins. In Ubuntu the package names would be gstreamer0.10-plugins-bad etc. (Or if you're using gstreamer 1.0, it'd obviously be gstreamer1.0-plugins-bad etc.) Either way, it's obviously not a bug in Parole. We might improve the codec installer in the future, feel free to help with that if you can.
