It's probably easier to write your own videosrc based on something like
videotestsrc that would produce the overlay stream. Then you could
define your 'program' as a textfile that lists image file-names for
timestamps and when you hit the timestamp you load the image (e.g. using
gdk-pixbuf) and send it out for all subsequent frames.
