As you were able to tell, it only took us about 100 lines of code to create a basic 1-on-1 video chat. To maximize the probability of a direct peer-to-peer connection, client private IP addresses are included in this candidate However, disclosure of these addresses has privacy implications. Several options can be implemented: Option 1 : add a TURN server in the ICE candidates When two WebRTC client call each other, the SIP server may add in the ICE candidate list of SDP offer and of the SDP answer, the address of a TURN server. To integrate an IP camera with a WebRTC application you first need to achieve media interoperability, i. Javascript Session Establishment Protocol (JSEP). I am glad that you have found a solution. Then, WebRTC Net API will exchange ICE candidates with the peer, until they both find the most "rational" triplets of IP address, port and transport (udp, dtls, and so on), for each stream (for example, audio, video, screen share, and so on) media capabilities are exchanged in SDP format (exactly as in SIP), and the two peers agree on. WebRTC engineer Justin Uberti provides more information about ICE, STUN, and TURN in the 2013 Google. How to Write a Resume Learn how to make a resume that gets interviews. We provided our own callback for this function. The JSEP approach delegates entirely to the appli-cation the responsibility for driving the signaling state machine: the application must call the right APIs at the right times, and convert the session Figure 1. This transferring of ICE candidates and exchange of other configuration information, such as media capabilities, is commonly called signaling.
