Hello community,

I am struggling with switching between multiple live streams. For example, I have five live streaming servers streaming(HTTP or RTSP) and I want to put some broker between those (five) streaming sources and destination so that output to the destination would be one video streaming (later I may change the streaming source again using switch). Broker plays role of switcher, My question is, is there such open source "switcher"? Or how this technology works?

here is link to similar question but I want some open source or some brief guidance about how it could be implemented: http://forums.creativecow.net/thread/117/858680


Thank You in advance
