AVPlayer too long and with delay to readyToPlay and play server music in swift

Question

I tried to buffer and immediately play remote url audio with swift language.

but problem is with long time to readyToPlay case and play.

for example a sound url takes about 12 to 15 second to run.

this is my code :

var asset: AVAsset!
var player: AVPlayer!
var playerItem: AVPlayerItem!

private var playerItemContext = 0

let requiredAssetKeys = [ "playable","hasProtectedContent"]

---

let url = URL(string: "http://sound_link.mp3")!
asset = AVAsset(url: url)

playerItem = AVPlayerItem(asset: asset,
                              automaticallyLoadedAssetKeys: requiredAssetKeys)
playerItem.addObserver(self,
                       forKeyPath: #keyPath(AVPlayerItem.status),
                       options: [.old, .new],
                       context: &playerItemContext)

player = AVPlayer(playerItem: playerItem)

that according to this (ExploringAVFoundation) documentation've done that

and for handle that player is ready to player to play i use observeValue func :

override func observeValue(forKeyPath keyPath: String?,of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

   guard context == &playerItemContext else {
        super.observeValue(forKeyPath: keyPath, of: object, change: change, context: context)
        return
    }

    if keyPath == #keyPath(AVPlayerItem.status) {
        let status: AVPlayerItemStatus
        if let statusNumber = change?[.newKey] as? NSNumber {
            status = AVPlayerItemStatus(rawValue: statusNumber.intValue)!
        } else {
            status = .unknown
        }
        // Switch over status value
        switch status {
        case .readyToPlay:
            print("readyToPlay \(status.rawValue)")
            player.play() // here play remote sound
        case .failed:
            print("readyToPlay \(status.rawValue)")
        case .unknown:
            print("failed \(status.rawValue)")
        }

    }
}

and this is returned log :

2017-02-08 13:44:00.626036 [15144:3747850] [aqme] 255: AQDefaultDevice (1): skipping input stream 0 0 0x0
readyToPlay 1
2017-02-08 13:44:02.631182 [15144:3747850] [aqme] 255: AQDefaultDevice (173): skipping input stream 0 0 0x0

in above log , take 4 sec to appear readyToPlay 1 then take 10 sec to play sound

sever speed is good and i tried to play server sound in Android and max time to buffer and play sound is about 3 sec.(in Android application) but in IOS buffering and play sound totally , totally take about 15 sec!

Thanks for your attention

Try to use this:

player.automaticallyWaitsToMinimizeStalling = false
