I am using the below code

guard let player, let pixelBuffer = videoOutput.copyPixelBuffer(forItemTime: player.currentTime(), itemTimeForDisplay: nil) else { return nil }
        let ciImage = CIImage(cvPixelBuffer: pixelBuffer)
        let context = CIContext(options: nil)
        guard let cgImage = context.createCGImage(ciImage, from: ciImage.extent) else { return nil }
        return UIImage(cgImage: cgImage)

I am not getting image in proper aspect ratio in which aspect ratio the video player was.
