Ok, suppose I wanna handle by myself the timed textoverlay. What I did in my function is exactly work this problem out. I wanna call a function which show on my screen a string set up with "text" and call it again after an interval to change the "text" property and start again, until the press of Stop button to stop the playing.  But it doesn't work well, cause not all of the lines are displayed e not in according to rimestamp.   On Fri, 2012-02-24 at 11:40 -0800, kususe wrote: > I coded a function to perform dynamic text overlay, displaying lines from a > file. > > def show_line(self): > next_line = self.curr_line + 1 > self.line = self.lines[self.curr_line] If you use the "text" or "markup" property, textoverlay will show the text as you set it on the property, immediately when you set it, for as long as you don't set the property to something else. If you want to show timed text, you can either a) handle the timing yourself, or b) use the GstController interface on the "text" property, to make it automatically show certain strings at a certain time in the stream, or c) push timed text/markup on textoverlay's text_sink sink pad. The buffers should contain UTF-8 text or pango markup, and the buffers should have timestamp and duration set on them. You could use an appsrc element to feed timed-text buffers to textoverlay, for example (or read them from file, like filesrc location=foo ! subparse ! ...)
