Maintaining good scroll performance when using AVPlayer

Question

I\'m working on an application where there is a collection view, and cells of the collection view can contain video. Right now I\'m displaying the video using AVPlayer

Answer 1

I've played around with all the answers above and found out that they're true only to a certain limit.

Easiest and the simplest way that worked for me so far is that the code you assign your AVPlayerItem to your AVPlayer instance in a background thread. I noticed that assigning the AVPlayerItem to the player on the main thread (even after AVPlayerItem object is ready) always takes a toll on your performance and frame rate.

Swift 4

ex.

let mediaUrl = //your media string
let player = AVPlayer()
let playerItem = AVPlayerItem(url: mediaUrl)

DispatchQueue.global(qos: .default).async {
    player.replaceCurrentItem(with: playerItem)
}
