WEBRTC interface invocation process for video calls based on WEBRTC

Scene:

1, A call B

2, B answer

3, A connected with B

Common steps:

Both A and B need to initialize the WEBRTC module to create the Peerconnectionfactory

Status of a in step 1

1. Create Peerconnection instances through Peerconnectionfactory

2. Call Peerconnection.createoffer

3, PeerConnection.Observer.onCreateSuccess (final sessiondescription ORIGSDP)

4. Send SDP to B

5, the following is the collection of Icecandidate, send the mobile phone icecandidate information sent to B, and then is the changes in various states,

These states are mainly: 1, icegatheringstate 2, signalingstate 3, Iceconnectionstate

Steps in step 2 of B

1, b after receiving the SDP sent by a, B creates the Peerconnection instance

2. B Set the received SDP to the Peerconnection instance

3. Call Peerconnection.createanswer in PeerConnection.Observer.onSetSuccess ()

4. PeerConnection.Observer.onCreateSuccess (final sessiondescription ORIGSDP) Send SDP message to a

5, through step 1 of 5

Step 3, A and B

1, A and b receive the icecandidate sent by the other side, set to their corresponding peerconnection instances

2. Find the right icecandidate then, establish the connection
