Dolby.io - File Presentation Service

This GitHub repo is a sample application that uses the File Presentation Service. It is using React.JS as front end technology and Node.JS as backend server.

Introduction

This sample application allows you to start a webinar type of presentation when participants can upload a PowerPoint file and start a presentation. Then other people can join the presentation as participants or listeners.

When you host a presentation, only you can control the slides. You have the possibility to navigate between the slides using the left and right arrow bellow the presentation slide, or directly by clicking on the slide thumbnail in the list of slides at the bottom of the screen.

You can display the notes from each slides.

Or not display them. The video can be rectangular.

Or a circle. All of this is configurable using React properties.

When you join as a participant, you can only see the current presentation slide and share your video and microphone. While connected as a listener, you can only see the current presentation slide but not share your camera and microphone.

Where to start

Clone this repo:

git clone https://github.com/dolbyio-samples/dolbyio-web-file-presentation-service

In the folder you've created, run the following command to install all the package dependencies:

npm install

If you haven't done so already, create an account on dolby.io, it is free so do it today! Go to your dashboard and for the first application, get your App Key and App Secret.

Create a .env file at the root of this folder and insert your consumer key and secret like that:

APP_KEY=<Your app key>
APP_SECRET=<Your app secret>
LIVE_RECORDING=false

Compile the React.JS application with the command:

npm run build

Start the Node.JS server with this command:

npm run start

Desktop Application

This project is now providing you with a way to build automatically a desktop application using the same code base as the web application and the electron framework.

Open the file ./desktop.js and change the serverUrl to match the address of your server. You do not need to change this when testing this application locally.

Build and run the desktop application with the command:

npm run desktop

Mixer Layout Application

This project automatically builds a custom Mixer Layout Application that you can use in your own projects. After you build the application, in the folder dist_mixer, you will find the two files you need to host for the mixer layout application. You can also directly use the one from this version of the repo by pointing the Recording Mixer Layout URL setting from the Dolby.io dashboard to this URL:

https://dolbyio-samples.github.io/dolbyio-web-file-presentation-service/index.html

Docker Image

You can build your own Docker image with this project using the command:

docker build -t fps .

To run the container, you must provide the two environment variables APP_KEY and APP_SECRET. And you can map the port 8081 of the container to your local port 80.

docker run --rm -it -p 80:8081/tcp --env "APP_KEY=<value>" --env "APP_SECRET=<value>" fps:latest

Now you should be able to access the application from this page: http://localhost
