About WebRTC

WebRTC is an open source project to enable real-time communication of audio, video, and data in web browsers and native apps. WebRTC is designed for peer-to-peer connections but includes fallbacks in case direct connections fail. Encryption is mandatory for WebRTC streams, so you must host the examples on a web server using SSL encryption.

Getting started

Set up WebRTC

You'll need to set up WebRTC for Wowza Streaming Engine to run the examples. For more information, see Set up WebRTC streaming with Wowza Streaming Engine.

Directory structure

In the src folder, you'll find examples for jQuery and React:

• jquery-example
  • css and images - Assets used by the example HTML pages.
  • lib - JavaScript files for managing the WebRTC setup.
    • AvMenu.js - Controls the selected input for publishing and screen sharing.
    • Settings.js - Creates a set of configuration settings and copy functionality.
    • SoundMeter.js - Provides an audio meter.
    • WowzaMungeSDP.js - Generates an SDP for peer signaling.
    • WowzaPeerConnectionPlay.js - Manages the signaling process for playback.
    • WowzaPeerConnectionPublish.js - Manages the signaling process for publishing.
    • WowzaWebRTCPlay.js - Controls the playback state.
    • WowzaWebRTCPublish.js - Controls the publishing state.
  • dev-view-publish.html - Example HTML page that can publish a WebRTC stream to Wowza Streaming Engine with video, audio, and screen share input.
  • dev-view-play.html - Example HTML page that can play back a WebRTC stream from Wowza Streaming Engine.
  • play.js and publish.js - JavaScript files that use files imported from the lib folder to control the WebRTC setup for publishing and playing streams.
• react-example
  • src
    • components - React components for the composite, meeting, play, and publish examples.
      • composite - CSS and JavaScript files that use components imported from other files to control the setup for compositing a WebRTC stream with multiple video and audio tracks.
        • Composite.js
        • CompositePublisher.js
        • Compositor.js
      • media
        • CompositorUserMedia.js
      • meeting - JavaScript files that use components imported from other files to control the setup for publishing a WebRTC stream with multiple participants.
      • play - JavaScript files that use components imported from other files to control the WebRTC setup for playing streams.
      • publish - JavaScript files that use components imported from other files to control the WebRTC setup for publishing streams.
    • webrtc - JavaScript files for managing the WebRTC setup.
      • replaceAudioTrack.js
      • replaceVideoTrack.js

Run the example code

Note: If you're not running the examples from localhost, an HTTPS connection is required for WebRTC to access local devices.

React

In the react-example directory, run the following command:

 $ npm start

jQuery

In the jquery-example directory, run the following command:

 $ npx serve

Go to localhost:5000/src/ to view the examples.
