Wie ändert man die Videoausrichtung des AVPlayers?

Question

Ich möchte die Wiedergabe eines Videos mit AVPlayer drehen. Gibt es eine Möglichkeit, sie um 90 Grad im Uhrzeigersinn zu drehen?
Hier einige Code:

self.player = AVPlayer(URL: NSURL(fileURLWithPath: dataPath)) 
playerLayer = AVPlayerLayer.init(player: self.player) 
playerLayer.frame = view.bounds 

playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill 
view.layer.addSublayer(playerLayer) 
player.play() 

UPDATE

Dieses funktioniert:

self.player = AVPlayer(URL: NSURL(fileURLWithPath: dataPath)) 
playerLayer = AVPlayerLayer.init(player: self.player)          
playerLayer.setAffineTransform(CGAffineTransformMakeRotation(CGFloat(M_PI)) 
playerLayer.frame = view.bounds   
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill 
view.layer.addSublayer(playerLayer) 
player.play() 

Answer 1

Wenn Sie Objective-C verwenden, wird der Code unten helfen.

Beispielcode:

#define degreeToRadian(x) (M_PI * x/180.0) 
#define radianToDegree(x) (180.0 * x/M_PI) 

- (void)rotateVideoPlayerWithDegree:(CGFloat)degree { 
    [_playerLayer setAffineTransform:CGAffineTransformMakeRotation(degreeToRadian(degree))]; 
} 

Answer 2

Hooni Antwort in Swift 3:

let affineTransform = CGAffineTransform(rotationAngle: degreeToRadian(90)) 
avPlayerLayer.setAffineTransform(affineTransform) 

func degreeToRadian(_ x: CGFloat) -> CGFloat { 
    return .pi * x/180.0 
}
