Twilio Video (WebRTC) for React Native



Platforms:

- iOS
- Android

People using a version < 1.0.1 please move to 1.0.1 since the project changed a lot internally to support the stable TwilioVideo version.

Installation

- react-native >= 0.40.0: install react-native-twilio-video-webrtc@1.0.1
- react-native < 0.40.0: install react-native-twilio-video-webrtc@1.0.0

$3


#### Option A: yarn

``shell
yarn add react-native-twilio-video-webrtc
`

#### Option B: npm

`shell
npm install react-native-twilio-video-webrtc --save
`

$3

To use this library with Expo we recommend using our config plugin that you can configure like the following example:

`json
{
"name": "my app",
"plugins": [
[
"react-native-twilio-video-webrtc",
{
"cameraPermission": "Allow $(PRODUCT_NAME) to access your camera",
"microphonePermission": "Allow $(PRODUCT_NAME) to access your microphone"
}
]
]
}
`

Also you will need to install expo-build-properties package:

`shell
npx expo install expo-build-properties
`

#### Expo Config Plugin Props

The plugin support the following properties:

- cameraPermission: Specifies the text to show when requesting the camera permission to the user.

- microphonePermission: Specifies the text to show when requesting the microphone permission to the user.

#### Option A: Install with CocoaPods (recommended)

1. Add this package to your Podfile

`ruby
pod 'react-native-twilio-video-webrtc', path: '../node_modules/react-native-twilio-video-webrtc'
`

Note that this will automatically pull in the appropriate version of the underlying TwilioVideo pod.

2. Install Pods with

`shell
pod install
`

#### Option B: Install without CocoaPods (manual approach)

1. Add the Twilio dependency to your Podfile

`ruby
pod 'TwilioVideo'
`

2. Install Pods with

`shell
pod install
`

3. Add the XCode project to your own XCode project's Libraries directory from

`
node_modules/react-native-twilio-video-webrtc/ios/RNTwilioVideoWebRTC.xcodeproj
`

4. Add libRNTwilioVideoWebRTC.a to your XCode project target's Linked Frameworks and Libraries

5. Update Build Settings

Find Search Paths and add $(SRCROOT)/../node_modules/react-native-twilio-video-webrtc/ios with recursive to Framework Search Paths and Library Search Paths

#### Post install

Be sure to increment your iOS Deployment Target to at least iOS 11 through XCode and your Podfile contains

`
platform :ios, '11.0'
`

#### Permissions

To enable camera usage and microphone usage you will need to add the following entries to your Info.plist file:

`
NSCameraUsageDescription
Your message to user when the camera is accessed for the first time
NSMicrophoneUsageDescription
Your message to user when the microphone is accessed for the first time
`

#### Known Issues

TwilioVideo version 1.3.8 (latest) has the following know issues.

- Participant disconnect event can take up to 120 seconds to occur. Issue 99
- AVPlayer audio content does not mix properly with Room audio. Issue 62

$3

As with iOS, make sure the package is installed:

`shell
yarn add https://github.com/blackuy/react-native-twilio-video-webrtc
`

Then add the library to your settings.gradle file:

`
include ':react-native-twilio-video-webrtc'
project(':react-native-twilio-video-webrtc').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-twilio-video-webrtc/android')
`

And include the library in your dependencies in android/app/build.gradle:
(if using gradle 4 or lower, replace implementation with compile below)

`
dependencies {
.....
.....
.....
implementation project(':react-native-twilio-video-webrtc')
}
`

You will also need to update this file so that you compile with java 8 features:

`
android {
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
}
`

Now you're ready to load the package in MainApplication.java. In the imports section, add this:

`java
import com.twiliorn.library.TwilioPackage;
`

Then update the getPackages() method:

`java
protected List getPackages() {
return Arrays.asList(
...
new TwilioPackage()
);
}
`

For most applications, you'll want to add camera and audio permissions to your AndroidManifest.xml file:

`xml






`

Newer versions of Android have a different permissions model. You will need to use the PermissionsAndroid
class in react-native in order to request the CAMERA and RECORD_AUDIO permissions.

$3

Under default settings, the Android build will fail if the total number of symbols exceeds a certain threshold. If you should encounter this issue when adding this library (e.g., if your build fails with com.android.dex.DexIndexOverflowException), you can turn on jumbo mode by editing your app/build.gradle:

`
android {
...
dexOptions {
jumboMode true
}
}
`

If you are using proguard (very likely), you will also need to ensure that the symbols needed by
this library are not stripped. To do that, add these two lines to proguard-rules.pro:

`
-keep class com.twilio.* { ; }
-keep class tvi.webrtc.* { ; }
`

Docs

You can see the documentation here.

Usage

We have three important components to understand:

`javascript
import {
TwilioVideo,
TwilioVideoLocalView,
TwilioVideoParticipantView,
} from "react-native-twilio-video-webrtc";
`

- TwilioVideo / is responsible for connecting to rooms, events delivery and camera/audio.
- TwilioVideoLocalView / is responsible local camera feed view
- TwilioVideoParticipantView / is responsible remote peer's camera feed view

Here you can see a complete example of a simple application that uses almost all the apis:

`javascript
import React, { Component, useRef } from "react";
import {
TwilioVideoLocalView,
TwilioVideoParticipantView,
TwilioVideo,
} from "react-native-twilio-video-webrtc";

const Example = (props) => {
const [isAudioEnabled, setIsAudioEnabled] = useState(true);
const [isVideoEnabled, setIsVideoEnabled] = useState(true);
const [status, setStatus] = useState("disconnected");
const [participants, setParticipants] = useState(new Map());
const [videoTracks, setVideoTracks] = useState(new Map());
const [token, setToken] = useState("");
const twilioRef = useRef(null);

const _onConnectButtonPress = () => {
twilioRef.current.connect({ accessToken: token });
setStatus("connecting");
};

const _onEndButtonPress = () => {
twilioRef.current.disconnect();
};

const _onMuteButtonPress = () => {
twilioRef.current
.setLocalAudioEnabled(!isAudioEnabled)
.then((isEnabled) => setIsAudioEnabled(isEnabled));
};

const _onFlipButtonPress = () => {
twilioRef.current.flipCamera();
};

const _onRoomDidConnect = ({ roomName, error }) => {
console.log("onRoomDidConnect: ", roomName);

setStatus("connected");
};

const _onRoomDidDisconnect = ({ roomName, error }) => {
console.log("[Disconnect]ERROR: ", error);

setStatus("disconnected");
};

const _onRoomDidFailToConnect = (error) => {
console.log("[FailToConnect]ERROR: ", error);

setStatus("disconnected");
};

const _onParticipantAddedVideoTrack = ({ participant, track }) => {
console.log("onParticipantAddedVideoTrack: ", participant, track);

setVideoTracks((originalVideoTracks) => {
originalVideoTracks.set(track.trackSid, {
participantSid: participant.sid,
videoTrackSid: track.trackSid,
});
return new Map(originalVideoTracks);
});
};

const _onParticipantRemovedVideoTrack = ({ participant, track }) => {
console.log("onParticipantRemovedVideoTrack: ", participant, track);

setVideoTracks((originalVideoTracks) => {
originalVideoTracks.delete(track.trackSid);
return new Map(originalVideoTracks);
});
};

return (

{status === "disconnected" && (

React Native Twilio Video
style={styles.input}
autoCapitalize="none"
value={token}
onChangeText={(text) => setToken(text)}
>
title="Connect"
style={styles.button}
onPress={_onConnectButtonPress}
>

)}

{(status === "connected" || status === "connecting") && (

{status === "connected" && (

{Array.from(videoTracks, ([trackSid, trackIdentifier]) => {
return (
style={styles.remoteVideo}
key={trackSid}
trackIdentifier={trackIdentifier}
/>
);
})}

)}

style={styles.optionButton}
onPress={_onEndButtonPress}
>
End

style={styles.optionButton}
onPress={_onMuteButtonPress}
>

{isAudioEnabled ? "Mute" : "Unmute"}


style={styles.optionButton}
onPress={_onFlipButtonPress}
>
Flip




)}

ref={twilioRef}
onRoomDidConnect={_onRoomDidConnect}
onRoomDidDisconnect={_onRoomDidDisconnect}
onRoomDidFailToConnect={_onRoomDidFailToConnect}
onParticipantAddedVideoTrack={_onParticipantAddedVideoTrack}
onParticipantRemovedVideoTrack={_onParticipantRemovedVideoTrack}
/>

);
};

AppRegistry.registerComponent("Example", () => Example);
`

Run the Example Application

To run the example application:

- Move to the Example directory: cd Example
- Install node dependencies: yarn install
- Install objective-c dependencies: cd ios && pod install
- Open the xcworkspace and run the app: open Example.xcworkspace

Migrating from 1.x to 2.x

- Make sure your pod dependencies are updated. If you manually specified a pod version, you'll want to update it as follows:

`
s.dependency 'TwilioVideo', '~> 2.2.0'
`

- Both participants and tracks are uniquely identified by their sid/trackSid field.
The trackId field no longer exists and should be replaced by trackSid. Commensurate with this change,
participant views now expect participantSid and videoTrackSid keys in the trackIdentity prop (instead of
identity and trackId).

- Make sure you're listening to participant events via onParticipant{Added/Removed}VideoTrack rather than onParticipant{Enabled/Disabled}Track`.
