Live streaming is becoming more and more popular. Platforms like Twitch and YouTube allow you to stream using tools like OBS directly to your audience in real-time from your desktop or laptop.
What if you wanted to build your own custom streaming platform embedded directly into your own website or app? In this post, I'll show you how to do this in just a few steps using Amplify Video.
The main tutorial will cover how to do this with a React Front end, but I'll also show how to do this with React Native.
Unlike most other Amplify services, the video services used in this tutorial do not fall under the free tier. Be sure to stop your video stream and delete the project when you are done if you are not using this in production. See pricing for these services here

This tutorial shows you how to build the streaming platform itself. If you're interested in embedding your existing Twitch, YouTube, or Mixer stream in your website, check out the react-stream package from Ryan Harris
Overview
This post shows you how to use the Amplify CLI, AWS Elemental, and Amplify Video (an Amplify CLI plugin by Sam Patzer) to deploy a video streaming service embeddable into any website or app.
We'll then look at how to embed the video player into a React app and test it out.
Under the hood, Amplify Video uses AWS Media Services like Elemental MediaLive and Elemental MediaStore, but because the CLI does all of the heavy lifting you will only have to work locally from your CLI to set everything up.
Elemental MediaLive is a fully managed and Serverless service that allows you to encode live video for broadcast and streaming to any device. It lets you create high-quality video streams for delivery to broadcast televisions and internet-connected multiscreen devices, like connected TVs, tablets, smart phones, and set-top boxes. The service works by encoding your live video streams in real-time, taking a larger-sized live video source and compressing it into smaller versions for distribution to your viewers.
This tutorial should take a total of about 15 minutes from start to finish.
To follow along and test out the completed app in this tutorial, you will need have OBS installed
Getting started
The first think you should do is install the latest version of the Amplify CLI and configure it with a user if you have not already done so:
$ npm i -g @aws-amplify/cli
$ amplify configure
For a video walkthrough of how to configure the Amplify CLI, click here
Next, install the Amplify Video CLI plugin:
$ npm i -g amplify-category-video
Now that the Amplify dependencies are set up on your computer, create a new React project and install Video.js:
$ npx create-react-app my-streaming-app
$ cd my-streaming app
$ npm install video.js
Creating the Amplify project
From within the root of the project, initialize a new Amplify app:
$ amplify init
# Choose the project name, environment name, your preferred text editor, and the defaults for the rest of the options.
# When prompted for your AWS Profile, choose the profile you created when you configured the Amplify CLI
Add a video resource
Now that the Amplify project has been configured, we can add a video resource!
To do so, we will run the Amplify add command:
$ amplify add video
# Follow the prompts. Note that the default values will be sufficient for this tutorial.
To deploy the service, run the Amplify push command:
$ amplify push
When deployed, the streaming service will automatically be started. To turn it off, either run
amplify video stopchoosing Yes to all prompts, or runamplify deleteto delete the project. Be sure not to leave the stream running when you are not using it as you will be billed for the usage.
Adding the video player to the React application
Next, open src/App.js and add the following:
import React from 'react'
import videojs from 'video.js'
import awsvideoconfig from './aws-video-exports'
import './App.css'
import 'video.js/dist/video-js.css'
class VideoPlayer extends React.Component {
componentDidMount() {
this.player = videojs(this.videoNode, this.props)
}
componentWillUnmount() {
if (this.player) {
this.player.dispose()
}
}
render() {
return (
<>
<div data-vjs-player style={{
width: 960, height: 540
}}>
<video ref={(node) => { this.videoNode = node; }} className="video-js" />
</div>
</>
);
}
}
const videoJsOptions = {
autoplay: true,
controls: true,
sources: [{
src: awsvideoconfig.awsOutputLiveLL,
}]
}
function App() {
return (
<div>
<nav style={nav}>
<p style={navHeading}>Live Streaming with React & AWS</p>
</nav>
<div style={container}>
<VideoPlayer { ...videoJsOptions } />
</div>
</div>
);
}
const nav = { padding: '0px 40px', height: 60, borderBottom: '1px solid #ddd', display: 'flex', alignItems: 'center' }
const container = { paddingTop: 40, width: 960, margin: '0 auto' }
const navHeading = { margin: 0, fontSize: 18 }
export default App
Enable OBS
Open Broadcast Software (OBS) can be automatically configured through Amplify video. Download OBS, make sure it's closed, and run the following command to configure an OBS profile to push to your Video resource.
$ amplify video setup-obs
Running the app
To run the app, run the start command:
$ npm start
Stopping the stream
When you are done with your stream, run the stop command to shut down your stream so you do not incur any additional streaming charges.
$ amplify video stop
? overwrite .../mylivestream-livestream-workflow.template: Y
? Would you like to overwrite all files? Y
? Are you sure you want to continue? Y
? overwrite ./src/aws-video-exports.js? Y
When the stream is turned off, it will be in Idle state. In Elemental MediaLive, the Idle state costs a little under 0.01 per hour. If you'd like to no incur any charges at all, delete the services with amplify delete.
Restarting the stream
If you'd like to turn the stream back on, run the following commands.
$ amplify video start
? overwrite .../mylivestream-livestream-workflow.template: Y
? Would you like to overwrite all files? Y
? Are you sure you want to continue? Y
? overwrite ./src/aws-video-exports.js? Y
Deleting the services
To delete the services from your account, run the delete command:
$ amplify delete
React Native
Amplify Video also works with React Native. To implement the stream on the React Native client, first install React Native Video
npm install react-native-video
To link the native dependencies, follow the guide here.
Next, set the video URI as the MediaStore URL
import Video from 'react-native-video';
<Video source={{uri: awsvideoconfig.awsOutputLiveLL}}
ref={(ref) => {
this.videoNode = ref
}}
/>
