AVPlayer play SKVideoNode video ,I just can not control the playback

问题

I am using the SpriteKit to play video,this is my code to create the SKVideoNode from AVPlayer:

    func CreateVideoViewWithAVPlayer(player:AVPlayer)
{
    video = SKVideoNode(AVPlayer: player)
    let frameLayer=AVPlayerLayer(player: player)
    //video?. = CGRectMake(0, 0, 100, 100)
    video?.size = CGSize(width: 1024, height: 768)
    println(player.currentItem)

    video?.anchorPoint = CGPoint(x: 0, y: 0)
    video?.position = CGPoint(x: 0, y: 0)

    backgroundColor = SKColor.blackColor()
    self.addChild(video!)
}

And I create a AVPlayer give the function:

        let scene01 = GameScene(size: view.bounds.size)
    scene01.CreateVideoViewWithAVPlayer(player!)

But When I call this "player.play()" ,I just show the first frame and not going any more. but if I use the "video" in the "CreateVideoViewWithAVPlayer" function ,It can play.

Another: if I use this code"

        skView.presentScene(scene01)
       //self.view.addSubview(skView)

（Comments the second） And user "player.play()" it can play (I can hear the sound). But if I use this:

           skView.presentScene(scene01)
       self.view.addSubview(skView)

I also can see the first frame.and can not run anymore.

Is there something I do is wrong? Help Me! Thanks A lot.

For no reason. You just can't use AVPlayer to control SKVideoNode's play or pause. but you can control monitor its play state via AVPlayer.

To play or pause a SKVideoNode, you have to use

video.play() / video.pause() // (video you declared here is the instance of SKVideoNode)
