SKVideoNode（嵌入在SKScene中）作为用于场景套件节点不起作用的纹理
我试图通过使用Scenekit将视频作为纹理映射到VR项目的原始圆柱体：作为SceneKit SCNTube对象的纹理嵌入SKScene中的SKVideoNode，并且我无法将视频显示为静止图像图像会。 下面的PLayground代码应该生成映射到柱面的移动视频，但映射不起作用：
编辑：添加单行在结束上市修正。 下面的代码应该工作
import UIKit
import SceneKit // for 3D mapping
import SpriteKit // for SKVideoNode
import QuartzCore // for basic animation
import XCPlayground // for live preview
import AVFoundation // for video playback engine
// create a scene view with an empty scene
var sceneView = SCNView(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
var scene = SCNScene()
sceneView.scene = scene
// start a live preview of that view
XCPShowView("The Scene View", view: sceneView)
// default lighting
sceneView.autoenablesDefaultLighting = true
// a geometry object
var tube = SCNTube(innerRadius: 1.99, outerRadius: 2, height: 3)
var tubeNode = SCNNode(geometry: tube)
scene.rootNode.addChildNode(tubeNode)
// video scene
let urlStr = NSBundle.mainBundle().pathForResource("sample", ofType: "mp4")
let url = NSURL(fileURLWithPath: urlStr!)
let asset = AVURLAsset(URL: url, options: nil)
let playerItem = AVPlayerItem(asset: asset)
let player = AVPlayer(playerItem: playerItem)
let videoNode = SKVideoNode(AVPlayer: player)
let spritescene = SKScene(size: CGSize(width: 1211, height: 431))
videoNode.size.width=spritescene.size.width
videoNode.size.height=spritescene.size.height
spritescene.addChild(videoNode)
// configure the geometry object
var myImage = UIImage.init(named: "BandImage.jpeg")
tube.firstMaterial?.diffuse.contents = spritescene
// set a rotation axis (no angle) to be able to
// use a nicer keypath below and avoid needing
// to wrap it in an NSValue
tubeNode.rotation = SCNVector4(x: 0.0, y: 1.0, z: 0.0, w: 0.0)
// animate the rotation of the torus
var spin = CABasicAnimation(keyPath: "rotation.w") // only animate the angle
spin.toValue = 2.0*M_PI
spin.duration = 3
spin.repeatCount = HUGE // for infinity
tubeNode.addAnimation(spin, forKey: "spin around")
// starts the video, solving the issue
sceneView.playing = true
我已经在github上发布了我的代码（以及一些示例全景内容），供任何想要获得有效示例代码或有兴趣在开源全景视频播放器上进行协作的人使用：

事实证明，它看起来像模拟器（和游乐场）不支持此功能。 将上面的代码移到一个项目并在设备上运行，我终于可以工作了。
因此，故事的寓意是 - 如果您将SKVideoNodes用作Scenekit的纹理，请使用实际设备进行测试。
