We want to give control to client(who broadcasts live sessions to server), so that he can show some images to viewers whenever the client wants. I followed your tutorial of image overlay, but it's bit different than what we are looking for. If the server already knows when client wants to show images, that tutorial is great.
How can the broadcaster communicate to server that he wanted to show images at a particular time in real-time?
Any help or suggestions will be appreciated..thanks
