Videos only plays audio

[abouzoubaa]

I am having a very bizarre issue where the video plays only audio but does not show: Here is the code:

import AppKit import CocoaYoutubeKit import WebKit

class PlayViewController: NSViewController {

private var player: YTSwiftyPlayer!

override func viewDidAppear() {
    super.viewDidAppear()
    self.view.window?.title = "Videos"        
    self.view.window?.titleVisibility = .hidden
    self.view.window?.titlebarAppearsTransparent = true
    self.view.window?.styleMask.insert(.fullSizeContentView)       
}

override func viewDidLoad() {
    super.viewDidLoad()

    player = YTSwiftyPlayer(
        frame: CGRect(x: 0, y: 0, width: 640, height: 480),
        playerVars: [.playsInline(true), .videoID("61-AN084GH0"), .loopVideo(true), .showRelatedVideo(false), .showModestbranding(true), .showInfo(false), VideoEmbedParameter.showControls(VideoControlAppearance.hidden)])
    
    player.autoplay = true        
    view.addSubview(player)
    player.delegate = self as YTSwiftyPlayerDelegate
    
    player.loadPlayer()
   }

}

Video shows only if I replace "view.addSubview(player)" with "view = player" For info the class PlayViewController is a SplitViewItem Controller. When I don't use a SplitViewController with 2 child controllers and use only a regular ViewController this problem disappears.

Thank you for helping.
