Not quite, the timeoverlay item is in the viewing branch of the 
pipeline, not prior to the tee, so wouldn't have been recorded.

pipeline:
			queue->filesink
		       /
filesrc (mpeg) -> tee -
		       \
			queue->decode->timeoverlay->xvimagesink


there are more pieces than that, but that's the gist of it.
