The Wikipedia article for Totem player says that "until version 2.27.1, it could alternatively be configured to use the Xine libraries instead of GStreamer".
I like Xine very much, but not its available GUIs (xine-ui, gxine, kaffeine are so awkward that I still prefer to stick with VLC, SMPlayer, Totem or Gnome Player).
Is it a way to make one of the most used "players" - especially Totem, maybe, but the present version 3.4 might not allow it - be used as a fronted for the Xine engine (xine-lib)?
(Also, is there a new GUI for Xine that I have not mentioned? The others listed here are abandoned.)
