Epris is a D-Bus service and command line client to listen to music. Unlike xmms2 or mpd, it uses GStreamer and D-Bus. It supports all formats supported by GStreamer, and can play both video and audio. It supports gap-less playback thanks to playbin2. It has an extensible command line interface, a small memory footprint, automatic deactivation, and an easy D-Bus interface for other UIs.
GSmartMix provides a smart control of the audio on GNOME. There is also an applet which allows manual adjustment of sound per application. Each application using GStreamer can benefit from this project without any intrusive patch. Other applications should implement the D-Bus interface proposed with GSmartMix to be seen by the smart manager.
hi nice! thanks for the update, I hope to see it in fedora soon.
