This article describes how to set up the Google Cast V3 feature in iOS devices.


The Cast functionality allows your videos to be cast from an iOS mobile device, via the Chromecast plugin, directly to a Kaltura Player Receiver App on a Chromecast-connected TV.

Before You Begin

Before you begin setting up the Cast feature, make sure you’ve read the article iOS Player SDK and Environment Setup - Getting Started.

Basic Definitions

  • Sender - A Cast enabled Kaltura Player running inside of a iOS Application; the Kaltura Player requires a Sender App ID.
  • Receiver - A Kaltura Player Receiver App that runs on the Chromecast device.

Google Cast Setup

To enable casting to Chromecast with the Kaltura Player iOS SDK, you will first need to import the Google Cast Framework and its dependent frameworks.


The supported version for Google Cast V3 iOS SDK is version 3.2.0.

Getting Started

To begin casting, follow these steps:

Connecting to Device

Follow the url below to initialize cast context:

Your final results on this step should be:

  • You will see a Chromecast icon on your application.
  • You can choose and connect/ disconnect to the Chromecast device.

Set up the Kaltura Environment

  1. Import the GoogleCastprovider module:
    #import <KalturaPlayerSDK/GoogleCastProvider.h>
  2. Configure a GoogleCastProvider shared instance, typically in your application’s application:didFinishLaunchingWithOptions: method, in AppDelegate class:

    [GoogleCastProvider sharedInstance];
  3. Create the KPPlayerConfig *configas follows:

         KPPlayerConfig *config = [[KPPlayerConfig alloc] initWithServer: @"{your-server-id}"
                                                                uiConfID: @"{your-ui-conf-id}"
                                                               partnerId: @"{your-pqrtner-id}"];
         config.entryId = @"{your-entry-id}";
  4. Next, add the following to your config instance:

         [config addConfigKey:@"chromecast.plugin" withValue:@"true"];
         [config addConfigKey:@"chromecast.useKalturaPlayer" withValue:@"true"];           
  5. Import the following classes:

     #import <GoogleCast/GoogleCast.h>
     #import <KalturaPlayerSDK/GoogleCastProvider.h>
  6. Create a castProvider property:

     @property (nonatomic, strong) GoogleCastProvider *castProvider;

7 . Before loading the player, perform the following:

    self.castProvider = [GoogleCastProvider sharedInstance]; 

Casting Media

To cast, set the castProvider property under KPViewController with GoogleCastProvider as the object you created:

    _player.castProvider = _castProvider;

The result for this step will cast your media via the Chromecast device.

Disconnecting from a Device

This process works out-of-the-box and doesn’t require configuration.

Reconnect to the Active Session

Attach the code below to your Start Casting implimentation:

if ([GCKCastContext sharedInstance].sessionManager.currentSession.
    remoteMediaClient.mediaStatus) {
    // Here you have to call to change media method under KPViewController
    [_playerViewController changeMedia:{current-entry-id}];

Change Media

To change media, use the changeMedia: method under KPViewController:

  [_playerViewController changeMedia:{your_value}];

To set a logo use the following:

  [self.castProvider setLogo:{custom_logo_image_url}];

Mini Controllers

If you wish to use mini controllers, see this url for details:


During casting, we advise using mini/extended controls over the player UI; see the sample below.


The following is a sample of using the mini/extended control:
