Steps to Build a Powerful Interactive Live-Streaming Platform
Preparation
- ZEGOCLOUD developer console account – Sign up
- A computer with video and audio support
- Recent and updated web browsers
- Basic understanding of web dev.
Follow the steps below to build interactive live streaming functionality into your apps using ZEGOCLOUD:
1: Create a project
- To set up a project folder for basic live streaming, follow this structure and create a new folder:
├── index.html
├── index.js- Paste the code below into the
index.htmlfile.
<html>
<head>
<meta charset="UTF-8">
<title>Zego Express Video Call</title>
<style type="text/css">
* {
font-family: sans-serif;
}
h1,
h4 {
text-align: center;
}
#local-video, #remote-video {
width: 400px;
height: 300px;
border: 1px solid #dfdfdf;
}
#local-video {
position: relative;
margin: 0 auto;
display: block;
}
#remote-video {
display: flex;
margin: auto;
position: relative !important;
}
</style>
</head>
<body>
<h1>
Zego RTC Video Call
</h1>
<h4>Local video</h4>
<div id="local-video"></div>
<h4>Remote video</h4>
<div id="remote-video"></div>
<script src="index.js"></script>
</body>
</html>2: Install and integrate the SDK
- Navigate to the folder where the index.js file is located using the “
cd” command in the terminal, then run “npm i zego-express-engine-webrtc” to install dependencies. - Add the SDK to the
index.jsfile by importing it.
import {ZegoExpressEngine} from 'zego-express-engine-webrtc'3: Instantiate a ZegoExpressEngine object
To create a ZegoExpressEngine instance, pass in your AppID as the “appID” parameter and the Server URL as the “server” parameter. These values can be obtained from the ZEGOCLOUD Admin Console.
const zg = new ZegoExpressEngine(appID, server);4: Verify that your browser supports WebRTC
Before publishing or playing a stream, utilize the checkSystemRequirements method to ensure that your browser supports WebRTC. Refer to the SDK’s browser compatibility documentation for further details regarding supported browser versions.
const result = await zg.checkSystemRequirements();
console.log(result);5: Log in to a room
To log in to a room, utilize the loginRoom method and provide a unique room ID as the “roomID” parameter, along with the login token from the previous step as the “token” parameter. Additionally, include the user ID and user name as the “userID” and “userName” parameters, respectively.
const result = await zg.loginRoom(roomID, token, {userID, userName}, {userUpdate: true});6: Publish streams
Create a local audio and video stream by invoking the createStream method, which by default captures video data from the camera and audio data from the microphone.
// After calling the CreateStream method, you need to wait for the ZEGO server to return the local stream object before any further operation.
const localStream = await zg.createStream();
// Obtain the video tag of the local video.
const localVideo = document.getElementById('local-video');
// The local stream is a MediaStream object. You can render audio and video by assigning the local stream to the SrCObject property of video or audio.
localVideo.srcObject = localStream;To publish a local audio and video stream to remote users, use the startPublishingStream method with the stream ID and media stream object obtained in the previous step as parameters.
zg.startPublishingStream(streamID, localStream)7: Play streams
Begin playback of a remote audio and video stream from the ZEGO server by utilizing the startPlayingStream method, which requires providing the corresponding stream ID as the streamID parameter.
const remoteStream = await zg.startPlayingStream(streamID);
// The remoteVideo object is the <video> or <audio> element on your webpage.
remoteVideo.srcObject = remoteStream;8: Cease publishing and playing of streams.
Terminate the publication of a local audio and video stream to remote users by calling the stopPublishingStream method and providing the corresponding stream ID as the streamID parameter.
zg.stopPublishingStream(streamID)After using a local media stream, call the destroyStream method to destroy it. Once the local media stream is destroyed, you must manually destroy the video element.
// localStream is the MediaStream object created when calling the createStream method.
zg.destroyStream(localStream)To halt the playback of a remote audio and video stream, use the stopPlayingStream method and pass the corresponding stream ID as the streamID parameter.
zg.stopPlayingStream(streamID)9: Log out of a room
To exit a room, use the logoutRoom method and pass the corresponding room ID as the roomID parameter.
zg.logoutRoom(roomID)Run a Demo
If you want to add interactive live streaming functionality to your apps, use the sample demo source code as a starting point.
