    Installation

    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.

    import {
      RTCPeerConnection,
      RTCIceCandidate,
      RTCSessionDescription,
      RTCView,
      MediaStream,
      MediaStreamTrack,
      mediaDevices,
      registerGlobals
    } from 'react-native-webrtc';

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

    const configuration = {"iceServers": [{"url": "stun:stun.l.google.com:19302"}]};
    const pc = new RTCPeerConnection(configuration);
     
    let isFront = true;
    mediaDevices.enumerateDevices().then(sourceInfos => {
      console.log(sourceInfos);
      let videoSourceId;
      for (let i = 0; i < sourceInfos.length; i++) {
        const sourceInfo = sourceInfos[i];
        if(sourceInfo.kind == "videoinput" && sourceInfo.facing == (isFront ? "front" : "environment")) {
          videoSourceId = sourceInfo.deviceId;
        }
      }
      mediaDevices.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}] : [])
        }
      })
      .then(stream => {
        // Got stream!
      })
      .catch(error => {
        // Log error
      });
    });
     
    pc.createOffer().then(desc => {
      pc.setLocalDescription(desc).then(() => {
        // Send pc.localDescription to peer
      });
    });
     
    pc.onicecandidate = function (event) {
      // send event.candidate to peer
    };
     
    // also support setRemoteDescription, createAnswer, addIceCandidate, onnegotiationneeded, oniceconnectionstatechange, onsignalingstatechange, onaddstream
     

    RTCView

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

    Rendering RTCView.

    <RTCView streamURL={this.state.stream.toURL()}/>
    Name Type Default Description
    mirror boolean false Indicates whether the video specified by "streamURL" should be mirrored during rendering. Commonly, applications choose to mirror theuser-facing camera.
    objectFit string 'contain' Can be contain or cover
    streamURL string '' This is mandatory
    zOrder number 0 Similarly to zIndex

    Custom APIs

    registerGlobals()

    By calling this method the JavaScript global namespace gets "polluted" with the following additions:

    • navigator.mediaDevices.getUserMedia()
    • navigator.mediaDevices.enumerateDevices()
    • window.RTCPeerConnection
    • window.RTCIceCandidate
    • window.RTCSessionDescription
    • window.MediaStream
    • window.MediaStreamTrack

    This is useful to make existing WebRTC JavaScript libraries (that expect those globals to exist) work with react-native-webrtc.

    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

    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.
