How to create a ticker-tape?

Tue Feb 2 00:37:59 PST 2016

I have been looking all over the web, but I couldn't find any information on
constructing a ticker tape in GStreamer. Does such an element exist or can
we use the textoverlay element. In the latter case, can we change the text,
xpos, ypos, deltax and deltay on the fly while the pipeline is in PLAYING
state? 

I wonder what the best practice would be. Any thoughts?
