How can I add a video view to my iOS .NET project?

Question

I want to play a video in my iOS .NET project. I have installed the NuGet package XamarinMediaManager version 1.2.2: https://github.com/Baseflow/XamarinMediaManager

But the problem is that I only hear the sound of the video when I debug on my iPad.

I have tried to right click my iOS project and Add-->New File-->iOS View Controller to my project but I don't know how to use it to create a subview for my video.

How can I create a video view in my iOS .NET project so that I can use it with XamarinMediaManager version 1.2.2?

I want to create a similar video view in my iOS project than in my Android project: https://learn.microsoft.com/en-us/answers/questions/1693485/how-can-i-find-out-if-my-video-view-is-on-top-of-m?comment=answer-1538504&page=1#comment-1590286

            UIApplication.Main(args, null, typeof(Program));
        }

        public override void FinishedLaunching(UIApplication app)
        {
            CrossMediaManager.Current.Init();
       
            RunGame();
        }

        }
        protected override void Update(GameTime gameTime)

Hello,

Why am I getting the exception?

This exception is thrown by the third-party package, please see their source code- https://github.com/Baseflow/XamarinMediaManager/blob/develop/MediaManager/Platforms/Ios/Video/VideoView.cs#L36

Because you are using MonoGame, and MonoGame has its own method to get the current controller, the rootcontroller will be null in MediaManager.

For this, please contact the owners of MediaManager to ask if there are any ways to avoid their GetCurrentUIViewController() method and pass the gameController of MonoGame.

(Note: Third-party tools are not supported on Q&A, please get further help from them)

In other way, you could try to present an AVPlayerViewController (without MediaManager package)

protected override void LoadContent()
{
     _spriteBatch = new SpriteBatch(GraphicsDevice);
 
     var player = new AVPlayer(NSUrl.FromString("https://videos.pexels.com/video-files/7356431/7356431-hd_1280_720_25fps.mp4"));
     var PlayerViewController = new AVPlayerViewController();
     PlayerViewController.Player = player;
 
     var gameController = this.Services.GetService(typeof(UIViewController)) as UIViewController;
     gameController.PresentViewController(PlayerViewController, true, null);
 
}
