I am developing a live streaming application which streams from files and a web cam interchangeably (it already works fine). I need to modify the stream on the fly by putting logo, running titles, etc on top of the content that I stream. And I really want to do it on the fly (i.e. in real time) so I cannot convert files in advance. I am going to use Xuggler for that. What is the right architecture to do it with Wowza? In other words: I cannot understand what is the right place for Xuggler inside Wowza?
