How to get AvPlayer Duration - Swift - ios

Question

How can I get AvPlayer to work like AvAudioPlayer. What I mean is, I cannot seem to get duration to work at all. Here is what I need to convert to AvPlayer:
import UIKit
import AVKit
import AVFoundation
class ModalViewController: UIViewController {
var audioPlayer = AVAudioPlayer()
let varSend = VarSend.sharedInstance
var timer:NSTimer!
var toggleState = 2
#IBOutlet weak var slider: UISlider!
#IBOutlet weak var sermonImage: UIImageView!
#IBOutlet weak var sermont: UILabel!
#IBOutlet weak var sermond: UILabel!
#IBOutlet weak var sermonE: UILabel!
#IBOutlet weak var sermonL: UILabel!
#IBOutlet weak var play: UIButton!
#IBOutlet var layer: UIView!
override func viewDidLoad() {
super.viewDidLoad()
let url = varSend.url
print("Setting up.")
do {
let data1 = NSData(contentsOfURL: NSURL(string:url)!)
audioPlayer = try AVAudioPlayer(data: data1!)
audioPlayer.prepareToPlay()
audioPlayer.volume = 1.0
audioPlayer.play()
} catch {
print("Error getting the audio file")
}
slider.maximumValue = Float(audioPlayer.duration)
timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("updateSlider"), userInfo: nil, repeats: true)
slider.setThumbImage(UIImage(named: "circle"), forState: .Normal)
slider.setThumbImage(UIImage(named: "circle"), forState: .Highlighted)
let title = varSend.sermonName
self.sermont.text = title
let date = varSend.sermonDate
self.sermond.text = date
let image = varSend.sermonPic
ImageLoader.sharedLoader.imageForUrl(image, completionHandler:{(image: UIImage?, url: String) in
self.sermonImage.image = image!
})
}
#IBAction func ChangeAudioTime(sender: AnyObject) {
audioPlayer.stop()
audioPlayer.currentTime = NSTimeInterval(slider.value)
audioPlayer.prepareToPlay()
audioPlayer.volume = 1.0
audioPlayer.play()
}
func updateSlider() {
slider.value = Float(audioPlayer.currentTime)
let currentTime = Int(audioPlayer.currentTime)
let minutes = currentTime / 60
let seconds = currentTime - minutes * 60
let con = Int(audioPlayer.duration)
let currentItem = con - currentTime
let minutesU = Int(currentItem / 60)
let secondsU = Int(currentItem % 60)
sermonE.text = NSString(format: "%02d:%02d", minutes,seconds) as String
let timeLeft = NSString(format: "%02d:%02d", minutesU,secondsU) as String
sermonL.text = "-\(timeLeft)"
if currentItem == 1 {
//audioPlayer.pause()
toggleState = 1
print(toggleState)
play.setImage(UIImage(named:"play.png"),forState:UIControlState.Normal)
}
}
#IBAction func playPauseButton(sender: AnyObject) {
let playBtn = sender as! UIButton
if toggleState == 1 {
audioPlayer.play()
toggleState = 2
playBtn.setImage(UIImage(named:"pause.png"),forState:UIControlState.Normal)
} else {
audioPlayer.pause()
toggleState = 1
playBtn.setImage(UIImage(named:"play.png"),forState:UIControlState.Normal)
}
}
#IBAction func play(sender: AnyObject) {
audioPlayer.play()
}
#IBAction func pause(sender: AnyObject) {
audioPlayer.pause()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func close(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
audioPlayer.stop()
}
}
And here is what I have tried already:
import UIKit
import Alamofire
import SwiftyJSON
import AVKit
import AVFoundation
import CoreMedia
class test: UIViewController {
var audioPlayer:AVPlayer!
var playerItem:AVPlayerItem!
var timer:NSTimer!
#IBOutlet weak var sermonE: UILabel!
#IBOutlet weak var sermonL: UILabel!
#IBOutlet weak var slider: UISlider!
override func viewDidLoad() {
super.viewDidLoad()
//let playerItem:AVPlayerItem!;
let playerURL = "example.com"
let steamingURL:NSURL = NSURL(string:playerURL)!
audioPlayer = AVPlayer(URL: steamingURL)
timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("updateSlider"), userInfo: nil, repeats: true)
}
func updateSlider() {
let item = audioPlayer?.currentItem
let durationInSeconds = CMTimeGetSeconds(item!.duration)
print(durationInSeconds)
}
#IBAction func ChangeAudioTime(sender: AnyObject) {
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func Play(sender: AnyObject) {
audioPlayer.play()
}
}
I have been searching for days and Apple's docs are very hard to make out.
I even tried
self.player.currentItem.asset.duration
from: How to get Duration from AVPlayer (Not AVAudioPlayer)?
Any help would be much appreciated.

Answer 1

Swift 2.0
loadedTimeRanges The array contains NSValue objects containing a CMTimeRange value
indicating the times ranges for which the player item has media data
readily available. The time ranges returned may be discontinuous.
So I call myplayer.getCurrentTrackDuration every 1 second and noticed that when I'm streaming I got the correct final duration after 3-4 second.
extension AVPlayer {
//run this every 1 second of streaming (or use KVO)
//In Http stream the duration it going to increase and probably finallize near to 7% of the total duration of the song
func getCurrentTrackDuration () -> Float64 {
guard let currentItem = self.currentItem else { return 0.0 }
guard currentItem.loadedTimeRanges.count > 0 else { return 0.0 }
let timeInSecond = CMTimeGetSeconds((currentItem.loadedTimeRanges[0].CMTimeRangeValue).duration);
return timeInSecond >= 0.0 ? timeInSecond : 0.0
}
}
