# Chromecast integration

This article describes how to integrate the Wowza Flowplayer SDK with the Google Cast SDK, to show and control media on a Google Cast device. The instructions assume you have installed the Wowza Flowplayer SDK and its dependencies in your app.

## Download the SDK

You can download the SDK through CocoaPods or manually.

### CocoaPods

Add `FlowplayerChromecast` together with its dependencies in your `Podfile`:


```bash
pod 'Flowplayer', '~> 3.0.3' # required
pod 'FlowplayerChromecast', '~> 3.0.3'
```

Execute `pod install` and you're ready to go.

info
* Use `Google Cast` iOS SDK version `4.7.0` or above
* Use `Flowplayer` version `3.0.3`  or above


### Manually

Download the XC framework of Wowza Flowplayer Chromecast iOS SDK from [here](https://github.com/flowplayer/flowplayer-ios/releases).

Only for Apple Silicon and CocoaPods
If you have `arm64` excluded as a valid architecture for Simulators, add the following code at the bottom of your Podfile file so that Protobuf, a dependency of Google Cast, can compile.


```ruby
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
			# Disable arm64 arch for Protobuf :(
			# As of writing this most dep. are x86_64 compiled and not arm64. 03.02.2022
      if target.name == "Protobuf"
        if config.name == "Debug"
					config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
        end
      end
    end
  end
end
```

## Add Google Cast to your project

Follow the instructions for how to add the Google Cast SDK to your project ([Develop iOS Sender App: Setup](https://developers.google.com/cast/docs/ios_sender)). This involves adding the Cast SDK, either manually or via third-party dependency managers like CocoaPods, and all its dependencies. Also, don't forget to add the desired capabilities in your Xcode project.

## How to use a custom Google Cast receiver app

If you have your own Cast receiver app, you can set the app id in your iOS app's Info.plist using the key `FlowplayerCastReceiverAppId`. If not set, the Wowza Flowplayer SDK will use Wowza Flowplayer's default Cast receiver app.

## Starting the manager

Early on in your app's startup process, you need to start the `FPCastManager`. The Wowza Flowplayer cast manager will, in turn, start the Google Cast context provided by the Google Cast SDK.

Your app delegate's `application:didFinishLaunchingWithOptions:` is a good place to start the cast manager:


```swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    // Start the cast manager.
    FPCastManager.shared.start()

    return true
}
```

## Add cast button

Please follow the Google Cast instructions to [add a Cast button](https://developers.google.com/cast/docs/ios_sender/integrate#add_a_cast_button).
