as taken from main.c of the gst-player:
gst_init (&argc, &argv);
gnome_init (PACKAGE, VERSION, argc, argv);
window = gnome_app_new ("gst-player", "GStreamer Player");
mplay = gst_media_play_new ();
gnome_app_set_contents (GNOME_APP (window), GTK_WIDGET(mplay));
gst_media_play_set_location (mplay, "pants.mpg");
gst_media_play_set_state (mplay, GST_STATE_PLAYING);
Granted, this thing has a seekbar and play/pause/stop buttons too in the
widget (that can be disabled). GstMediaPlay is build on top of GstPlay,
which is just a GObject, so it requires a GtkPlug to embed the window
(but allows for a KDE/Qt based player).
