i have the same issues as you did. the reason is in iOS 10.xx , if you export video with animationTool . You will meet the trouble like that . try to fix them by remove this code .

something like that

 mainComposition.animationTool =  AVVideoCompositionCoreAnimationTool(postProcessingAsVideoLayer: videoLayer, in: parentlayer)

Answer 2

Here's how I set a AVPlayerLayer with the video working (I think what you're missing is the videoGravity parameter).

let bundle = Bundle.main
let moviePath = bundle.path(forResource: "myVideo", ofType: "mp4")
let moviePlayer = AVPlayer(url: URL(fileURLWithPath: moviePath!))

playerLayer = AVPlayerLayer(player: moviePlayer)
playerLayer.frame = movieView.bounds
playerLayer.videoGravity = AVLayerVideoGravityResizeAspect
movieView.layer.addSublayer(playerLayer)
playerLayer.player?.play()

It's the frame height or width is equal to zero
