Installation

Usage

现在,您可以像在浏览器中一样使用 WebRTC。 在您的 index.ios.js/index.android.js 中,您可以要求 WebRTC 导入 RTCPeerConnection、RTCSessionDescription 等。

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

任何关于使用 RTCPeerConnection、RTCSessionDescription 和 RTCIceCandidate 的东西都像浏览器。 支持大多数 WebRTC API,请参阅文档

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

但是,渲染视频流应该使用 React 方式。

渲染 RTCView。

<RTCView streamURL={this.state.stream.toURL()}/>
NameTypeDefaultDescription
mirrorbooleanfalseIndicates whether the video specified by "streamURL" should be mirrored during rendering. Commonly, applications choose to mirror theuser-facing camera.
objectFitstring'contain'Can be contain or cover
streamURLstring''This is mandatory
zOrdernumber0Similarly to zIndex

Custom APIs

registerGlobals()

通过调用此方法,JavaScript 全局命名空间会被以下添加项“污染”:

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

这对于使现有的 WebRTC JavaScript 库(期望这些全局变量存在)与 react-native-webrtc 一起工作很有用。

MediaStreamTrack.prototype._switchCamera()

此功能允许在视频轨道中切换前置/后置摄像头 即时,无需添加/删除轨道或重新协商。

VideoTrack.enabled

从1.67版本开始,当设置本地视频轨道的启用状态为 false,相机将关闭,但轨迹将保持活动状态。 环境 它回到 true 将重新启用相机。

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()}/>
NameTypeDefaultDescription
mirrorbooleanfalseIndicates whether the video specified by "streamURL" should be mirrored during rendering. Commonly, applications choose to mirror theuser-facing camera.
objectFitstring'contain'Can be contain or cover
streamURLstring''This is mandatory
zOrdernumber0Similarly 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

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.
