Привет, я реализовал видеоплеер xamarin, который описан по следующей ссылке https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/video-player/
Я загружаю видео через код в папку с документами приложения, путь к которому такой
[/Users/vaibhavjain/Library/Developer/CoreSimulator/Devices/{GUID}/data/Containers/Data/Application/{GUID}/Documents/MediaDocuments/Nature1.mp4]
Теперь я проверил, что видео правильно загружены по этому пути, но когда я передаю этот путь в качестве источника на видеоплеер выше, он не может воспроизвести его
Я предполагаю, что игрок не может достичь пути или ожидает относительный путь, но я не могу найти ни одного примера типа пути, который я должен предоставить.
вот код для кастомного рендерера на ios
public class VideoPlayerRenderer : ViewRenderer<VideoPlayer, UIView>
{
AVPlayer player;
AVPlayerItem playerItem;
AVPlayerViewController _playerViewController; // solely for ViewController property

// Set Player property to AVPlayer

// Use the View from the controller as the native control
SetNativeControl(_playerViewController.View);
