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

react-native-webrtc	WebRTC Version	arch(ios)	arch(android)	npm published	note	additional picks
1.69.0	M69 commit (24012) (+16-24348)	x86_64 i386 armv7 arm64	armeabi-v7a x86	:heavy_check_mark:
master	M69 commit (24012) (+16-24348)	x86_64 i386 armv7 arm64	armeabi-v7a x86	:warning:	test me plz

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.
