What is Onicecandidate in WebRTC?

The RTCPeerConnection property onicecandidate property is an event handler which specifies a function to be called when the icecandidate event occurs on an RTCPeerConnection instance. This happens whenever the local ICE agent needs to deliver a message to the other peer through the signaling server.

What is a RTCPeerConnection?

The RTCPeerConnection interface represents a WebRTC connection between the local computer and a remote peer. It provides methods to connect to a remote peer, maintain and monitor the connection, and close the connection once it’s no longer needed.

What is addIceCandidate?

How do I use RTCPeerConnection?

WebRTC – RTCPeerConnection APIs

1. Register the onicecandidate handler.
2. Register the onaddstream handler.
3. Register the message handler.
4. Utilize getUserMedia() to set up your local media stream and add it to the RTCPeerConnection object using the addStream() method.
5. Start offer/answer negotiation process.

What is WebRTC ice?

ICE stands for Interactive Connectivity Establishment. It is a standard method of NAT traversal used in WebRTC. It is defined in IETF RFC 5245. ICE deals with the process of connecting media through NATs by conducting connectivity checks.

What is peer JS?

But there is some good news; PeerJS is a WebRTC framework that abstracts away all of the ice and signalling logic so that you can focus on the functionality of your application. There are two parts to PeerJS, the client-side framework and the server.

The read-only property sdpMid on the RTCIceCandidate interface returns a DOMString specifying the media stream identification tag of the media component with which the candidate is associated. This ID uniquely identifies a given stream for the component with which the candidate is associated.

How do you end a call in WebRTC?

The most graceful way of doing this is to close the connection using the close() function, which you can do in an event listener for the hang up button. When the connection has been closed, you also want to display the correct HTML content so you can just call your showCallContent() function.

How does WebRTC ice work?

ICE deals with the process of connecting media through NATs by conducting connectivity checks. ICE collects all available candidates (local IP addresses, reflexive addresses – STUN ones and relayed addresses – TURN ones). All the collected addresses are then sent to the remote peer via SDP.
