如何将AVPlayer放入SCNPlane (ARKit)中？

import UIKit
import SceneKit
import ARKit
import AVFoundation

class ViewController: UIViewController, ARSCNViewDelegate {
    
    @IBOutlet var sceneView: ARSCNView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建一个SCNPlane对象
        let plane = SCNPlane(width: 0.2, height: 0.2)
        
        // 创建一个AVPlayer对象
        guard let videoURL = Bundle.main.url(forResource: "video", withExtension: "mp4") else { return }
        let player = AVPlayer(url: videoURL)
        
        // 创建一个AVPlayerLayer对象
        let playerLayer = AVPlayerLayer(player: player)
        playerLayer.videoGravity = .resizeAspect
        
        // 将AVPlayerLayer对象添加到SCNPlane的contents属性中
        plane.firstMaterial?.diffuse.contents = playerLayer
        
        // 创建一个SCNNode对象，并将SCNPlane对象设置为其几何体
        let planeNode = SCNNode(geometry: plane)
        
        // 设置SCNNode的位置
        planeNode.position = SCNVector3(0, 0, -1)
        
        // 将SCNNode对象添加到场景中
        sceneView.scene.rootNode.addChildNode(planeNode)
        
        // 播放视频
        player.play()
    }
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        
        // 配置AR会话
        let configuration = ARWorldTrackingConfiguration()
        sceneView.session.run(configuration)
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        
        // 暂停视频播放
        sceneView.session.pause()
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // 释放任何可以被重新创建的资源
    }
}
