StreamLayer Element Visibility Guide

When the StreamLayer Element opens or closes, your app may need to adjust its interface — for example, hiding player controls or resizing the video. The SLROverlayDelegate provides a callback for tracking these visibility changes.

Detect Visibility Changes

Implement the handleActionShown delegate method to respond when the StreamLayer Element opens or closes:

SLRVideoPlayer: SLROverlayDelegate {
  
  public func handleActionShown(_ action: SLRActionShown) {
    if action.source == .overlay {
      if action.isShown {
        print("overlay opened")
      } else {
        print("overlay closed")
      }
    }
  }

}

Use the action.source property to distinguish between different types of visibility events, and action.isShown to determine whether the element is now visible or hidden.
