How to get Duration from AVPlayer (Not AVAudioPlayer)?

Question

I would like to make a UISlider(scrubber) for my AVPlayer. But since this is not an AVAudioPlayer, it doesn\'t have a built in duration. Any suggestion on how to create the

Answer 1

For Swift to get duration in seconds

if let duration = player.currentItem?.asset.duration {
    let seconds = CMTimeGetSeconds(duration)
    print("Seconds :: \(seconds)")
}

Answer 2

As of iOS 4.3, you can use the slightly shorter:

self.player.currentItem.duration;

Answer 3

self.player.currentItem.asset.duration

Got it!

Answer 4

Noted from StitchedStreamPlayer

You should use player.currentItem.duration

- (CMTime)playerItemDuration
{
    AVPlayerItem *thePlayerItem = [player currentItem];
    if (thePlayerItem.status == AVPlayerItemStatusReadyToPlay)
    {        
        /* 
         NOTE:
         Because of the dynamic nature of HTTP Live Streaming Media, the best practice 
         for obtaining the duration of an AVPlayerItem object has changed in iOS 4.3. 
         Prior to iOS 4.3, you would obtain the duration of a player item by fetching 
         the value of the duration property of its associated AVAsset object. However, 
         note that for HTTP Live Streaming Media the duration of a player item during 
         any particular playback session may differ from the duration of its asset. For 
         this reason a new key-value observable duration property has been defined on 
         AVPlayerItem.

         See the AV Foundation Release Notes for iOS 4.3 for more information.

        return([playerItem duration]);
    }

    return(kCMTimeInvalid);
}

Swift 5

Put this code inside some function that you desired :

let duration = player.currentItem?.duration.seconds ?? 0
let playDuration = formatTime(seconds: duration) //Duration RESULT

Create a function called: formatTime(seconds: Double)

func formatTime(seconds: Double) -> String {
    let result = timeDivider(seconds: seconds)
    let hoursString = "\(result.hours)"
    var minutesString = "\(result.minutes)"
    var secondsString = "\(result.seconds)"

    if minutesString.count == 1 {
        minutesString = "0\(result.minutes)"
    }
    if secondsString.count == 1 {
        secondsString = "0\(result.seconds)"
    }

    var time = "\(hoursString):"
    if result.hours >= 1 {
        time.append("\(minutesString):\(secondsString)")
    }
    else {
        time = "\(minutesString):\(secondsString)"
    }
    return time
}

Then, another function to translate seconds to hour, minute and second. Since the seconds that by layerLayer.player?.currentItem?.duration.seconds will have long Double, so this is needed to become Human Readable.

func timeDivider(seconds: Double) -> (hours: Int, minutes: Int, seconds: Int) {
    guard !(seconds.isNaN || seconds.isInfinite) else {
        return (0,0,0)
    }
    let secs: Int = Int(seconds)
    let hours = secs / 3600
    let minutes = (secs % 3600) / 60
    let seconds = (secs % 3600) % 60
    return (hours, minutes, seconds)
}

Hope it's complete your answer.
