如何在 Swift 中使用 Arkit 在图像上播放托管视频？

Question

当视频存储在本地时，我可以毫无问题地播放视频，但现在我想播放托管在我的谷歌驱动器上的视频。

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        let configuration = ARImageTrackingConfiguration()

        if let trackedImages = ARReferenceImage.referenceImages(inGroupNamed: "TestImages", bundle: Bundle.main){
            configuration.trackingImages = trackedImages

            configuration.maximumNumberOfTrackedImages = 1
        }

        // Run the view's session
        ARView.session.run(configuration)
    }

这是我将视频渲染到图像上的函数：

func renderer(_ renderer: SCNSceneRenderer, nodeFor anchor: ARAnchor) -> SCNNode? {

        let node = SCNNode()

        if let imageAnchor = anchor as? ARImageAnchor{

            let videoNode = SKVideoNode(fileNamed: "Test.mp4")

            videoNode.play()

            let videoScene = SKScene(size: CGSize(width: 1080, height:720 ))

            videoScene.addChild(videoNode)

            let plane = SCNPlane(width: imageAnchor.referenceImage.physicalSize.width, height: imageAnchor.referenceImage.physicalSize.height)

            videoNode.position = CGPoint(x: videoScene.size.width/2, y: videoScene.size.height/2)

            videoNode.yScale = -1.0

            plane.firstMaterial?.diffuse.contents = videoScene

            let planeNode = SCNNode(geometry: plane)

            planeNode.eulerAngles.x = -.pi/2

            node.addChildNode(planeNode)


        }

        return node
    }

我是 ARKIT 的新手，所以我只学习基本功能并享受使用它们的乐趣。

Answer 1

您的代码看起来不错。您唯一需要更改的是您定义 videoNode 的行

例子：

let videoNode = SKVideoNode(url: URL(fileURLWithPath: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"))

希望这会有所帮助！
