AVPlayer play with update label cause an issue - ios

Question

I have an issue with AVPlayer play and same time updates label.
I have timer that updates label with progress of player, but that stuck my video at same position...check below image..After button click timer starts and cause an issue..
Code:
func playVideo() {
let path = NSBundle.mainBundle().pathForResource("videoname", ofType:"mp4")
let fileURL = NSURL(fileURLWithPath: path!)
moviePlayer = AVPlayer(URL: fileURL)
// Play the video
moviePlayer!.play()
}
#IBAction func progresss(sender: UIButton) {
self.meterTimer = NSTimer.scheduledTimerWithTimeInterval(0.1,
target:self,
selector:"updateAudioMeter:",
userInfo:nil,
repeats:true)
}
func updateAudioMeter(timer:NSTimer) {
lbltime.text = "\(CMTimeGetSeconds(moviePlayer!.currentItem.currentTime()))"
}

Note:please add video in bundle if you are use sample project.I just delete video because of file size
Question
How to avoid this? and why this happens because when I used MPMovieController it works great.

Answer 1

From your sample code the problem is below function:
override func viewDidLayoutSubviews() {
let layer = AVPlayerLayer(player: moviePlayer)
layer.frame = self.viewPlayer.frame
self.viewPlayer.layer.addSublayer(layer)
}
This will resize your layer view every time when your label update so just remove and add that code into playVideo method and your method will be:
func playVideo() {
let path = NSBundle.mainBundle().pathForResource("video", ofType: "MOV")
let url = NSURL.fileURLWithPath(path!)
moviePlayer = AVPlayer(URL: url)
moviePlayer!.allowsExternalPlayback = false
var introPlayerLayer = AVPlayerLayer(player: moviePlayer)
viewPlayer.layer.addSublayer(introPlayerLayer)
introPlayerLayer.frame = viewPlayer.bounds
moviePlayer!.play()
}
And call this method in viewDidAppear instead of viewDidLoad method and your complete code will be:
import UIKit
import MediaPlayer
import AVFoundation
class ViewController: UIViewController {
var moviePlayer : AVPlayer?
var meterTimer : NSTimer!
#IBOutlet weak var viewPlayer: UIView!
#IBOutlet weak var lbltime: UILabel!
override func viewDidAppear(animated: Bool) {
playVideo()
}
func playVideo() {
let path = NSBundle.mainBundle().pathForResource("video", ofType: "MOV")
let url = NSURL.fileURLWithPath(path!)
moviePlayer = AVPlayer(URL: url)
moviePlayer!.allowsExternalPlayback = false
var introPlayerLayer = AVPlayerLayer(player: moviePlayer)
viewPlayer.layer.addSublayer(introPlayerLayer)
introPlayerLayer.frame = viewPlayer.bounds
moviePlayer!.play()
}
#IBAction func progresss(sender: UIButton) {
moviePlayer?.seekToTime(kCMTimeZero)
moviePlayer?.addPeriodicTimeObserverForInterval(CMTimeMakeWithSeconds(1, 1), queue: nil, usingBlock: {
(CMTime) -> Void in
self.updateProgressBar()
})
}
func updateProgressBar(){
var timeNow = Int(self.moviePlayer!.currentTime().value) / Int(self.moviePlayer!.currentTime().timescale)
var currentMins = timeNow / 60
var currentSec = timeNow % 60
var duration: String = "\(currentMins):\(currentSec)"
self.lbltime.text = duration
}
}

I have written a sample code for Objective-C, you can convert same in swift for your project accordingly.
// Implement following code in AVPlayer observer method for `AVPlayerStatusReadyToPlay` state
[avPlayer addPeriodicTimeObserverForInterval:CMTimeMakeWithSeconds(interval, NSEC_PER_SEC)
queue:NULL
usingBlock:
^(CMTime time)
{
// update label value here, it keeps invoking periodically internally.
CMTime playerDuration = [self playerItemDuration];
}];
// Method to get Player current time
- (CMTime)playerItemDuration
{
AVPlayerItem *thePlayerItem = [avPlayer currentItem];
if (thePlayerItem.status == AVPlayerItemStatusReadyToPlay)
{
return([avPlayerItem duration]);
}
return(kCMTimeInvalid);
}
if you simply want to update it then invoke playerItemDuration to get current time, but make it asynchronous process.
