WebRTC Record video on server

Question

I am researching about WebRTC and I opened thousands of tabs about it. but still I exactly don't know what code I should write at where !!!

I am going to have a website using asp.net 4.5 and IIS 8 (if needed). It should have a vidoe conference. but for security resons, I need to record videos from both sides in the server. So I think I can't use p2p. please help me by providing some step-by-step tutorial, and please do not give me any more links!!! (I have no more room to open a new tab :D)

Answer 1

You can do what you're trying to do with WebRTC - but you want to enforce a relay, so the data flows through the server and you can write the frames to disk. What that'll do is essentially eliminate the P2P part, but still make all the data flow over UDP rather than TCP, keeping performance high and bandwidth low. It's about the best you can hope for without going with something like flash media server.

For support in IE, you'll need a plugin of some sort - it doesn't support native WebRTC, and there's no support for native UDP connections in Flash either, so it's either Java applets or custom plugins.

We've done the heavy lifting for basically what you're trying to do with IceLink (I work @ Frozen Mountain). Oh, and to enforce the relay, you have to suppress any peer-candidate pairs that don't come through the relay (since WebRTC can have multiple candidates from multiple sources, just suppressing the options you don't want will ensure that the relay is the only option left).

Hope that helps!
