See:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-libs/html/GstBaseSrc.html#id484395

Basically:

  gst_element_send_event (pipeline, gst_event_new_eos ());

  ... wait for EOS to appear on pipeline's GstBus,
      then set_state to NULL

This is what gst-launch -e does (see gst-launch.c code).
