I want to build a community website with videoconferencing functionality integrated. I would prefer to provide this from within the browser, so I'm looking for a Java- or Flash-based solution.
Also, it would be nice to spare bandwidth by having the clients stream their audio and video data without using a central server (like the way Skype works, for example).
Is there a reasonably mature open-source project that meets these criteria?
When doing Voice over IP, UDP is preferred, and web browser plugins usually lacks support for UDP and P2P-connections.
But there is a solution. You have to use Adobe Flash Player 10 and the Adobe Stratus for this. This is actually what Chatroulette is using for P2P streamed video chat.
