Callbacks

The BambuserCommerceSDK provides the BambuserVideoPlayerDelegate protocol for handling communications from a Bambuser video player instance. By implementing this protocol, your class can receive callback messages when new events occur or errors are encountered.

Methods:

• onNewEventReceived(id: String, event: BambuserEventPayload):

  • Called when a new event is received from the video player.
  • Parameters:
    • id: A unique identifier for the video player.
    • event: A BambuserEventPayload containing the event type and associated data.

• onErrorOccurred(id: String, error: Error):

  • Called when an error occurs within the video player.
  • Parameters:
    • id: A unique identifier for the video player.
    • error: The error encountered by the video player.

• onVideoStatusChanged(_ id: String, state: BambuserVideoState):

  • Called when the playback state of the video changes (e.g., playing, paused, ended).
  • Parameters:
    • id: A unique identifier for the video player.
    • state: A BambuserVideoState enum value indicating the current playback state.

• onVideoProgress(_ id: String, duration: Double, currentTime: Double):

  • Called to report playback progress of the video.
  • Parameters:
    • id: A unique identifier for the video player.
    • duration: The total duration of the video in seconds.
    • currentTime: The current playback time in seconds.

• onThumbnailTapped(_ id: String):

  • Called when the video thumbnail is tapped.
  • Parameters:
    • id: A unique identifier for the video player. Example Implementation

class ViewController: BambuserVideoPlayerDelegate {
    func onNewEventReceived(id: String, event: BambuserEventPayload) {
        print("Player \(id) sent event: \(event)")
    }
    func onErrorOccurred(id: String, error: Error) {
        print("Error in player \(id): \(error.localizedDescription)")
    }
    func onVideoStatusChanged(_ id: String, state: BambuserVideoState) {
        print("Player \(id) changed state to: \(state)")
    }
    func onVideoProgress(_ id: String, duration: Double, currentTime: Double) {
        print("Player \(id) progress: \(currentTime)/\(duration) seconds")
    }
    func onThumbnailTapped(_ id: String) {
        print("Player [\(id)] thumbnail was tapped")
    }
}

Player States

BambuserVideoState values reported via onVideoStatusChanged and accessible through playerView.currentPlayerState:

State	When it fires
.loading	Player is initialising or buffering
.playing	Playback is active (after autoplay or play())
.paused	Playback was paused via pause()
.error	An unrecoverable error occurred (e.g. invalid show ID)

Error Handling

When the player encounters an unrecoverable error — such as an invalid or unpublished show ID — two callbacks fire:

1. onVideoStatusChanged with state .error
2. onErrorOccurred with the underlying Error

class ViewController: BambuserVideoPlayerDelegate {

    func onVideoStatusChanged(_ id: String, state: BambuserVideoState) {
        if state == .error {
            // Hide the player and show a fallback UI
            DispatchQueue.main.async {
                self.playerView.removeFromSuperview()
                self.showErrorBanner("This show is unavailable.")
            }
        }
    }

    func onErrorOccurred(id: String, error: Error) {
        print("Player \(id) error: \(error.localizedDescription)")
        // Log to your analytics or crash reporting service
    }
}

Common causes of .error state:

• Invalid, deleted, or unpublished show ID passed to type: .live(id:)
• Network failure during player initialisation

Picture-in-Picture (PiP) Delegate

The BambuserCommerceSDK provides Picture-in-Picture (PiP) support through the PictureInPictureController interface, available via each BambuserPlayerView instance. PiP allows video content to continue playing in a floating overlay while users interact with other parts of the app or their device.

PictureInPictureController The PictureInPictureController lets you control and monitor PiP mode.

Properties:

• isEnabled: A Bool indicating whether PiP is allowed for the video container.
• isActive: A Bool indicating whether PiP is currently active.
• delegate: An optional BambuserPictureInPictureDelegate to receive PiP state change callbacks.

Methods:

• start(): Starts PiP mode programmatically, enabling the video to continue in a floating overlay.
• stop(): Stops PiP mode and removes the floating overlay.

Example:

// Access the controller from your player view
let pipController = playerView.pipController

// Enable PiP (if not already enabled)
pipController.isEnabled = true

// Start PiP
pipController.start()

// Stop PiP
pipController.stop()

Notes

• PiP is enabled by default for live and pre-recorded videos.
• PiP is disabled by default for shoppable videos.
• Make sure to set isEnabled appropriately before calling start() or before PiP mode starts automatically.

BambuserPictureInPictureDelegate Methods:

• onPictureInPictureStateChanged(_ id: String, state: PlayerPipState): Called for all PIP changes in the app.
• which contains PlayerPipState as follow:

public enum PlayerPipState {
    /// Indicates that Picture-in-Picture mode is about to start.
    case willStart

    /// Indicates that Picture-in-Picture mode is about to stop.
    case willStop

    /// Indicates that Picture-in-Picture mode has started.
    case started

    /// Indicates that Picture-in-Picture mode has stopped.
    case stopped

    /**
     Indicates that the Picture-in-Picture session has been restored.

     This occurs when the user taps “Go to full screen,” bringing the app back to the foreground (if app is in background) and disabling Picture-in-Picture mode.
     */
    case restored
