AVPlayer autostart in SceneKit

Question

I have an AVPlayer used in SpriteKit as a material of SceneKit node. However, the AVPlayer will always auto start! I have tried to put the code in viewDidLoad or viewWillAppear (as some answers), but it still load automatically.

My code is something like this:

var apple1984Video:AVPlayer!

override func viewDidLoad() {
    super.viewDidLoad()
    ...
    apple1984Video = AVPlayer(url: Bundle.main.url(forResource: "apple1984", withExtension:"mp4")!)
    apple1984Video.actionAtItemEnd =.none
    apple1984Video.pause()

    let ad1 = addVideo(apple1984Video, name:"apple1984", position:SCNVector3(-0.1, -0.1, -0.5))
    scene.rootNode.addChildNode(ad1)
    ...
}

What can I do to stop the autoplay?

PS: here's the addVideo function but it is primary related to SceneKit/SpriteKit stuffs. I did not called play() in other parts of program.

func addVideo(_ player:AVPlayer, name:String, position:SCNVector3) -> SCNNode {
    let spriteKitScene = SKScene(size: CGSize(width: sceneView.frame.width, height: sceneView.frame.height))
    spriteKitScene.scaleMode = .aspectFill
    spriteKitScene.backgroundColor = UIColor(red: 0.5, green: 0.5, blue: 0.5, alpha: 0.5)

    // Create the SpriteKit video node, containing the video player

    let videoNode = SKVideoNode(avPlayer: player)
    videoNode.position = CGPoint(x: spriteKitScene.size.width / 2.0, y: spriteKitScene.size.height / 2.0)
    videoNode.size = spriteKitScene.size
    videoNode.yScale = -1.0
    videoNode.alpha = 0.9
    spriteKitScene.addChild(videoNode)

    let geometry = SCNPlane(width: 0.4, height: 0.3)
    let node = SCNNode(geometry: geometry)

    geometry.firstMaterial?.isDoubleSided = true
    geometry.firstMaterial?.diffuse.contents = spriteKitScene

    node.name = name
    node.position = position
    player.pause()
    return node
}

hmmm possibly show u the addVideo func? And there is no videoPlayer.play() later on? — Fluidity, Jul 18 '17 at 12:11
Done, thought they are not quite related as they are primary SceneKit/SpriteKit stuffs. I have also tried returning SKVideoNode instead of AVPlayer but it also autoplayed. — Lim Thye Chean, Jul 18 '17 at 12:16
if you pause the video inside the func before add it to the scene? — Simone Pistecchia, Jul 18 '17 at 12:26
Check if the video player attached to the video node is the same as the vidso player you create. It could be making a copy, and you are pausing the wrong instance — Knight0fDragon, Jul 18 '17 at 13:34
Thanks to @Knight0fDragon suggestion, I create the AVPlayer outside the function and pass in the player, make sure it is the only copy. And I placed pause() to the player before calling and inside the function. But the video still auto-play. — Lim Thye Chean, Jul 18 '17 at 22:50
no no, you got it backwards, you need to verify the video player inside the SKVideoNode — Knight0fDragon, Jul 18 '17 at 22:51
Note: If you are targeting iOS11 you can try setting the AVPlayer directly to the material property. — Toyos, Jul 18 '17 at 22:51
@Toyos this works, and might solved the issue... let me test, thanks! — Lim Thye Chean, Jul 18 '17 at 22:55
I would be inclined to try this out in SpriteKit first, just to reduce the number of debugging variables. I recently made a small project with avPlayer and SKVideoNode that is working properly, if you want to look at it. https://stackoverflow.com/a/44989379/6593818 — Fluidity, Jul 18 '17 at 23:51
@Toyos solved the issue but removing the SpriteKit layer directly! Applying AVPlayer to material works. — Lim Thye Chean, Jul 19 '17 at 01:11
@Knight0fDragon thanks. I tried this in my previous version (didn't try it after the changes) and it does not work. But the issue is now solved with SpriteKit layer directly removed. — Lim Thye Chean, Jul 19 '17 at 01:12
