Hi
You need HTML5 WebRTC support for live audio video chat. I worked lot with Red5 ( free source) and Flash RTMP AV chat and text messaging. It has been very cool but now Flash/ActionScript is outdated so we need to do same with Red5 Pro 's WebRTC, NODE JS and SOCKET IO.
Please notice that Red5 pro is not free source. There is Ant Media Server which is clone of Red5 and cost less.
Message me if you are interested.
