Actually looking at champlain-gtk source code it already requires clutter so the best way to do this is to use clutter-gtk to embed a canvas into your app and add the champlain clutter actor to the canvas.  My opinion is there is no reason for Champlain to have a Champlain-gtk.  Here si what I do to embed gstreamer:

from gi.repository import Gtk, Clutter, GtkClutter, ClutterGst

window = Gtk.Window()
ClutterGst.init(sys.argv)       
clutter_window = GtkClutter.Embed()
window.add(clutter_window)
video_texture = ClutterGst.VideoTexture()
video_texture.set_filename("data/intro.ogv")

stage = self.clutter_window.get_stage()
stage.add_actor(video_texture)

window.connect('delete', lambda x: Gtk.main_quit())
window.show_all()

Gtk.main()
