I want to use a GStreamer-based video player, preferably using a GTK frontend, on LXDE. I'm afraid Totem could possibly bring in a lot of GNOME dependencies, hence seeking alternatives.
Well you could try Parole which actually is media player of xfce so will install xfce dependencies.
Or you could try xnoise which is said to support gstreamer but xnoise seems much more oriented towards music than videos but it can play videos according to its review on the above link.
Can be installed from ppa:
