react-native-webrtc-with-snapshot v1.69.0

react-native-webrtc

A WebRTC module for React Native.

• Support iOS / Android.
• Support Video / Audio / Data Channels.

NOTE for Expo users: this plugin doesn't work unless you eject.

Comunity

Everyone is welcome to you our Discourse community to discuss any React Native and WebRTC related topics.

WebRTC Revision

Since 0.53, we use same branch version number like in webrtc native. please see wiki page about revision history

format:

${branch_name} stable (${branched_from_revision})(+${Cherry-Picks-Num}-${Last-Cherry-Picks-Revision})

• the webrtc revision in brackets is extracting frrom Cr-Branched-From instead `Cr-Commit-Position
• the number follows with + is the additional amount of cherry-picks since Branched-From revision.

note:

the order of commit revision is nothing to do with the order of cherry-picks, for example, the earlier committed cherry-pick-#2 may have higher revision than cherry-pick-#3 and vice versa.

Installation

• iOS
• Android

Usage

Now, you can use WebRTC like in browser. In your index.ios.js/index.android.js, you can require WebRTC to import RTCPeerConnection, RTCSessionDescription, etc.

var WebRTC = require('react-native-webrtc');
var {
  RTCPeerConnection,
  RTCIceCandidate,
  RTCSessionDescription,
  RTCView,
  MediaStream,
  MediaStreamTrack,
  getUserMedia,
} = WebRTC;

Anything about using RTCPeerConnection, RTCSessionDescription and RTCIceCandidate is like browser.
Support most WebRTC APIs, please see the Document.

var configuration = {"iceServers": [{"url": "stun:stun.l.google.com:19302"}]};
var pc = new RTCPeerConnection(configuration);

let isFront = true;
MediaStreamTrack.getSources(sourceInfos => {
  console.log(sourceInfos);
  let videoSourceId;
  for (let i = 0; i < sourceInfos.length; i++) {
    const sourceInfo = sourceInfos[i];
    if(sourceInfo.kind == "video" && sourceInfo.facing == (isFront ? "front" : "back")) {
      videoSourceId = sourceInfo.id;
    }
  }
  getUserMedia({
    audio: true,
    video: {
      mandatory: {
        minWidth: 500, // Provide your own width, height and frame rate here
        minHeight: 300,
        minFrameRate: 30
      },
      facingMode: (isFront ? "user" : "environment"),
      optional: (videoSourceId ? [{sourceId: videoSourceId}] : [])
    }
  }, function (stream) {
    console.log('dddd', stream);
    callback(stream);
  }, logError);
});

pc.createOffer(function(desc) {
  pc.setLocalDescription(desc, function () {
    // Send pc.localDescription to peer
  }, function(e) {});
}, function(e) {});

pc.onicecandidate = function (event) {
  // send event.candidate to peer
};

// also support setRemoteDescription, createAnswer, addIceCandidate, onnegotiationneeded, oniceconnectionstatechange, onsignalingstatechange, onaddstream

However, render video stream should be used by React way.

Rendering RTCView.

var container;
var RCTWebRTCDemo = React.createClass({
  getInitialState: function() {
    return {videoURL: null};
  },
  componentDidMount: function() {
    container = this;
  },
  render: function() {
    return (
      <View>
        <RTCView streamURL={this.state.videoURL}/>
      </View>
    );
  }
});

And set stream to RTCView

container.setState({videoURL: stream.toURL()});

Custom APIs

MediaStreamTrack.prototype._switchCamera()

This function allows to switch the front / back cameras in a video track on the fly, without the need for adding / removing tracks or renegotiating.

VideoTrack.enabled

Starting with version 1.67, when setting a local video track's enabled state to false, the camera will be closed, but the track will remain alive. Setting it back to true will re-enable the camera.
