How to get video location playing by AVPlayer?

Question

I am using AVPlayer to play the video from AWS CloudFront server. Here is my code:

let playerItem = AVPlayerItem(url: url)
let player = AVPlayer(playerItem: playerItem)

playerViewCont.player = player

present(playerViewCont, animated: false) { [weak self] in
    self?.playerViewCont.player?.play()
}

AVPlayer playing video from url every time its present. I want to save the video locally and for that I am seeking any function or way with which I can get downloaded video by AVPlayer so I can move it to another location for later use.

Any help?
