PLAYING => NULL => PLAYING seems to work.

The following program seems to execute fine here.

GstElement *pipeline = gst_parse_launch ("videotestsrc ! glupload ! glimagesink", NULL);

gst_element_set_state (pipeline, GST_STATE_PLAYING);
g_usleep (1000000);
gst_element_set_state (pipeline, GST_STATE_READY);
g_usleep (1000000);
gst_element_set_state (pipeline, GST_STATE_PLAYING);
g_usleep (1000000);
gst_element_set_state (pipeline, GST_STATE_NULL);
