我的例子實現了這個功能：https://github.com/martijn00/XamarinMediaManager/blob/master/MediaManager/MediaManager.Plugin.iOSUnified/MediaManagerImplementation.cs

你應該使用的代碼是：

  player.ReplaceCurrentItemWithPlayerItem(streamingItem); 
      streamingItem.AddObserver(this, new NSString("status"), NSKeyValueObservingOptions.New, player.Handle); 
      streamingItem.AddObserver(this, new NSString("loadedTimeRanges"), NSKeyValueObservingOptions.Initial | NSKeyValueObservingOptions.New, player.Handle); 

      player.CurrentItem.SeekingWaitsForVideoCompositionRendering = true; 
      player.CurrentItem.AddObserver(this, (NSString)"status", NSKeyValueObservingOptions.New | 
       NSKeyValueObservingOptions.Initial, StatusObservationContext.Handle); 

      NSNotificationCenter.DefaultCenter.AddObserver(AVPlayerItem.DidPlayToEndTimeNotification, async (notification) => 
      { 
       await PlayNext(); 
      }, player.CurrentItem); 

      player.Play();
