React Native Livestream Component

api.video is the video infrastructure for product builders. Lightning fast video APIs for integrating, scaling, and managing on-demand & low latency live streaming features in your app.

Project description

This module is made for broadcasting rtmp live stream from smartphone camera

Getting started

:warning: The React Native Live Stream SDK is designed for 0.69.1 version of React Native. Using the SDK with >0.69.1 of React Native can cause unexpected behaviour

Installation

npm install @api.video/react-native-livestream

or

yarn add @api.video/react-native-livestream

Note: if you are on iOS, you will need two extra steps:

1. Don't forget to install the native dependencies with Cocoapods

cd ios && pod install

1. This project contains swift code, and if it's your first dependency with swift code, you need to create an empty swift file in your project (with the bridging header) from XCode. Find how to do that

Permissions

To be able to broadcast, you must:

1. On Android: ask for internet, camera and microphone permissions:

<manifest>
  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.RECORD_AUDIO" />
  <uses-permission android:name="android.permission.CAMERA" />
</manifest>

Your application must dynamically require android.permission.CAMERA and android.permission.RECORD_AUDIO.

2. On iOS: update Info.plist with a usage description for camera and microphone

<key>NSCameraUsageDescription</key>
<string>Your own description of the purpose</string>

<key>NSMicrophoneUsageDescription</key>
<string>Your own description of the purpose</string>

3. On react-native you must handle the permissions requests before starting your livestream. If permissions are not accepted you will not be able to broadcast.

Code sample

import React, { useRef, useState } from 'react';
import { View, TouchableOpacity } from 'react-native';
import { LiveStreamView } from '@api.video/react-native-livestream';

const App = () => {
  const ref = useRef(null);
  const [streaming, setStreaming] = useState(false);

  return (
    <View style={{ flex: 1, alignItems: 'center' }}>
      <LiveStreamView
        style={{ flex: 1, backgroundColor: 'black', alignSelf: 'stretch' }}
        ref={ref}
        camera="back"
        enablePinchedZoom={true}
        video={{
          fps: 30,
          resolution: '720p',
          bitrate: 2*1024*1024, // # 2 Mbps
          gopDuration: 1, // 1 second
        }}
        audio={{
          bitrate: 128000,
          sampleRate: 44100,
          isStereo: true,
        }}
        isMuted={false}
        onConnectionSuccess={() => {
          //do what you want
        }}
        onConnectionFailed={(e) => {
          //do what you want
        }}
        onDisconnect={() => {
          //do what you want
        }}
      />
      <View style={{ position: 'absolute', bottom: 40 }}>
        <TouchableOpacity
          style={{
            borderRadius: 50,
            backgroundColor: streaming ? 'red' : 'white',
            width: 50,
            height: 50,
          }}
          onPress={() => {
            if (streaming) {
              ref.current?.stopStreaming();
              setStreaming(false);
            } else {
              ref.current?.startStreaming('YOUR_STREAM_KEY');
              setStreaming(true);
            }
          }}
        />
      </View>
    </View>
  );
}

export default App;
