私は同じタスクを持っていました!私の解決策hereを見てください。
私は基本的にChromaKeyMaterialをLësha Turkowskiから実装し、ビデオを配置して再生するためにこのコードを書いています。
import UIKit
import ARKit
class ARTransVC: UIViewController{
@IBOutlet weak var arSceneView: ARSCNView!
let configuration = ARWorldTrackingConfiguration()
private var player: AVPlayer = {
guard let url = Bundle.main.url(forResource: "FY3A4278", withExtension: "mp4") else { fatalError() }
return AVPlayer(url: url)
}()
override func viewDidLoad() {
super.viewDidLoad()
self.arSceneView.debugOptions = [ARSCNDebugOptions.showWorldOrigin, ARSCNDebugOptions.showFeaturePoints]
self.arSceneView.session.run(configuration)
//a delay for ARKit to capture the surroundings
DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
// A SpriteKit scene to contain the SpriteKit video node
let spriteKitScene = SKScene(size: CGSize(width: self.arSceneView.frame.width, height: self.arSceneView.frame.height))
spriteKitScene.scaleMode = .aspectFit
spriteKitScene.backgroundColor = .clear
spriteKitScene.scaleMode = .aspectFit
//Create the SpriteKit video node, containing the video player
let videoSpriteKitNode = SKVideoNode(avPlayer: self.player)
videoSpriteKitNode.position = CGPoint(x: spriteKitScene.size.width/2.0, y: spriteKitScene.size.height/2.0)
videoSpriteKitNode.size = spriteKitScene.size
videoSpriteKitNode.yScale = -1.0
videoSpriteKitNode.play()
spriteKitScene.addChild(videoSpriteKitNode)
// To make the video loop
self.player.actionAtItemEnd = .none
NotificationCenter.default.addObserver(
self,
selector: #selector(ARTransVC.playerItemDidReachEnd),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: self.player.currentItem)
// Create the SceneKit scene
let scene = SCNScene()
self.arSceneView.scene = scene
//Create a SceneKit plane and add the SpriteKit scene as its material
let background = SCNPlane(width: CGFloat(1), height: CGFloat(1))
background.firstMaterial?.diffuse.contents = spriteKitScene
let chromaKeyMaterial = ChromaKeyMaterial()
chromaKeyMaterial.diffuse.contents = self.player
let backgroundNode = SCNNode(geometry: background)
backgroundNode.geometry?.firstMaterial?.isDoubleSided = true
backgroundNode.geometry!.materials = [chromaKeyMaterial]
backgroundNode.position = SCNVector3(0,0,-2.0)
scene.rootNode.addChildNode(backgroundNode)
//video does not start without delaying the player
//playing the video before just results in [SceneKit] Error: Cannot get pixel buffer (CVPixelBufferRef)
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self.player.seek(to:CMTimeMakeWithSeconds(1, 1000))
self.player.play()
}
}
}
@objc func playerItemDidReachEnd(notification: NSNotification) {
if let playerItem: AVPlayerItem = notification.object as? AVPlayerItem {
playerItem.seek(to: kCMTimeZero, completionHandler: nil)
}
}
まだこの問題上の任意の進展? – Felix
