Can't help you with that, sorry :) I'm sure you can find code examples
using "compositor" or "glvideomixer" somewhere though.

You can do that in code by

1) getting the input/sink pad from the mixer:

  pad = gst_element_get_static_pad (mixer, "sink_0");
  ...
  gst_object_unref (pad);


2) It has properties for position/zorder/alpha:

  g_object_set (pad, "xpos", 10,  "ypos", 10, NULL);

Cheers
