Dolby.io Real-time Streaming UIKit for iOS

Overview

The Dolby.io Real-time Streaming UIKit for iOS is design to help iOS developers reduce the complexity of building a Dolby.io Real-time Streaming monitoring applications for iOS.

The package consists of three components:

• DolbyIORTSUIKit: The high-level UI components can be used to develop a real-time streaming monitoring app for iOS with Dolby.io.
• DolbyIORTSCore: The logic between DolbyIORTSUIKit and Dolby.io Real-time Streaming iOS SDK.
• DolbyUIUIKIt: The basic UI components used by DolbyIORTSUIKit.

Info: There are two parties in a real-time streaming. A publisher who broadcasts a streaming. A monitor(viewer) who consumes a streaming. This UIKit is targeting to a monitor who consumes a streaming.

Requirements

This setup guide is validated on both Intel/M1-based MacBook Pro running macOS 13.4.

• Xcode Version 14.3.1 (14E300c)
• iPhone device or simulator running iOS 15.0

Getting Started

This guide demostrates how to use the Real-time Streaming UI components to quickly build a Real-time Steaming monitoring app on an iOS device.

Build a Sample App

Get started by a working sample app, see below.

• Create a new Xcode project
• Choose the iOS App as template
• Fill in the Product Name
• Select "SwiftUI" as Interface
• Select "Swift" as Language
• Create the project in a folder
• Add this UIKit as dependencies to the newly created project.
  • Go to File > Add Packages...
  • Put the URL of this repo in the pop-up window's top-right corner text field
  • Use Up to Next Major Version in the Dependency Rule
  • Click the Add Package button
  • Choose and add these packages DolbyIORTSCore, DolbyIORTSUIKit, and DolbyIOUIKIt to the target
  • Click the Add Package button
• Copy and replace the code to ContentView.swift
• Compile and Run on an iOS target

import SwiftUI

// 1. Include Dolby.io UIKit and related packages
import DolbyIORTSCore
import DolbyIORTSUIKit

struct ContentView: View {
    // 2. State to show the real-time streaming or not
    @State private var showStream = false

    var body: some View {
        NavigationView {
            ZStack {
            
            	// 3. Navigation link to the streaming screen if `showStream` is true
                NavigationLink(destination: StreamingScreen(isShowingStreamView: $showStream), isActive: $showStream) { EmptyView() }
                Button ("Start Stream") {
                
                	// 4. Asynchronize task connects the publisher with the given stream name and account ID. The stream name and 
                	// account ID pair here is from a demo stream. It can be replaced by a pair being given by a publisher who has 
                	// signed-up up the Dolby.io service. 
                    Task {
                        let success = await StreamCoordinator.shared.connect(streamName: "multiview", accountID: "k9Mwad")
                        
                        // 5. Show the real-time streaming if connect successfully
                        await MainActor.run { showStream = success }
                    }
                }
            }.preferredColorScheme(.dark)
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

Get a Dolby.io account

To publish a real-time stream, a Dolby.io account is necessary

• A Dolby.io account
• Start a video streaming broadcasting, see here
• The Stream name and Account ID pair from the video streaming above

To setup your Dolby.io account, go to the Dolby.io dashboard and complete the form. After confirming your email address, you will be logged in.

Installation

This UIKit package uses Swift Packages. You can add this package site URL as dependencies to your app. Detail can be find here

Info: The main branch is constantly under development. Get a tagged branch for a stable release.
