Howevery I want to add changing text like frame number in case that text
becomes on the screen like "this is 1. frame" and then "this is 2.frame" and
goes on with,
but it gives me error which means to me , element's property (text) can't be
changed in the pipeline. So what should I do to put dynamic text on the
frame? In the next step, I want to add these texts to my frame where I get
from appsink. Any help will be nice.
