How create a peer-to-peer Video Streaming WEB app?

I was wondering if it's possibile to create a web-client that can connect two users 开发者_开发百科and then it sends their webcam stream to each other. This should happen without using Red5 or any other flash/media server.

What protocol can I use? What api etc...

Look at Jabber(XMPP) protocol. Depending on the the web framework you select, clients are available in most major languages.

Flash 10 introduces a peer-to-peer model. Here's a post on it:

WebRTC might be what you are looking for. Here in you end up with a web application, completely void of plugins or Flash, which streams content peer-to-peer. Check out the Demos given here. Although Chrome is the only browser where this has been implemented completely as of now, the others are quickly catching up. You could go through the documentation of the API given here.

No. It's not possible to do what you describe.

You'll either need some form of server in the middle, or you'll need to build an ActiveX control or Browser Plugin to handle your communication.

Flash and Java are not options, because they are specifically limited to communicating only with their server of origin.
