Progress of playbackLikelyToKeepUp - ios

Question

When using an AVPlayer, is there a way to get the progress of playbackLikelyToKeepUp? I was thinking I could look at loadedTimeRanges to see how much has been buffered so far, but from what I understand, the playbackLikelyToKeepUp property is some internally made prediction and does not provide a value of how much data is needed for it to be true.
To put this into perspective, what I'm trying to do is to have a progress view that reaches 100% just as the video starts playing.

To begin playing when AVPlayer will play continuously, you can observe the Key-Value changes on the playbackLikelyToKeepUp, like this:
let PlayerKeepUp = "playbackLikelyToKeepUp"
var isPlayerReady:Bool = false
and then in your Initialiser you add:
// adding the Observers for Status:
self.player?.currentItem?.addObserver(self, forKeyPath: PlayerKeepUp, options: ([NSKeyValueObservingOptions.New, NSKeyValueObservingOptions.Old]), context: &PlayerItemObserverContext)
And Finally, to track when the player is ready to play without getting stuck:
// MARK: KVO Observing Methods:
override public func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
switch (keyPath, context) {
case (PlayerKeepUp as String, &PlayerItemObserverContext):
if(self.player.currentItem?.playbackLikelyToKeepUp == true) {
self.isPlayerReady = true
// HERE YOU FILL UP YOUR PROGRESS VIEW :-)
self.delegate?.playerReady(self.playerURL! as String)
}
break
default:
super.observeValueForKeyPath(keyPath, ofObject: object, change: change, context: context)
}
}
Last but not least, remember to Remove your KVO observance or else you'll crash when de-allocating the player:
deinit {
// Remove observer:
self.player?.currentItem?.removeObserver(self, forKeyPath: PlayerKeepUp, context: &PlayerItemObserverContext)
}
Hope this helps :-)
