I am working on Video
player based Application
, where I have to play multiple
Videos
using AVPlayer
. Each video
has to play with some CIFilter
effect so I am using VideoComposition
for that.
My problem is when there is more than one Video
in my VideoArray
then first Video
is playing perfectly with audio, but when it’s coming to the next Video then AVPlayer
shows black screen but audio
sound of the Video
is coming. I am invoking the below common method whenever Video
is playing:
private func createPlayerForVideoIndex(index: Int){
guard let videoComposition = videoFilterComposition else { return }
self.player?.pause()
self.audioPlayer?.pause()
playerLayer?.removeFromSuperlayer()
let video = videoClipsArray.object(at: index) as! VideoFileModel
playerItem = AVPlayerItem(url:NSURL(fileURLWithPath: video.localFilePath) as URL)
playerItem?.videoComposition = videoComposition
self.player = AVPlayer(playerItem: playerItem)
playerLayer = AVPlayerLayer(player: player)
playerLayer?.videoGravity = AVLayerVideoGravityResizeAspectFill
playerLayer?.frame = CGRect(x:0, y:67, width:self.view.frame.size.width, height:250)
self.view.layer.addSublayer(playerLayer!)
if !myScrollView.isDescendant(of: self.view) {
myScrollView.frame = (playerLayer?.frame)!
myScrollView.delegate = self
myScrollView.isPagingEnabled = true
myScrollView.showsHorizontalScrollIndicator = false
myScrollView.showsVerticalScrollIndicator = false
myScrollView.backgroundColor = UIColor.clear
self.view.addSubview(myScrollView)
}
self.view.bringSubview(toFront: self.pageControl)
self.myScrollView.contentSize = CGSize(width:self.myScrollView.frame.size.width * 4,height: self.myScrollView.frame.size.height)
let startSeconds : Int64 = Int64(video.leftRangeValue)
let targetTime:CMTime = CMTimeMake(startSeconds, 1)
self.player?.seek(to: targetTime)
let endSeconds : Int64 = Int64(video.rightRangeValue)
self.player?.currentItem?.forwardPlaybackEndTime = CMTimeMake(endSeconds, 1)
self.player?.volume = videoVolumeSlider.value
self.player?.play()
self.audioPlayer?.play()
self.player?.rate = video.slowFastMotionRate
}
I assume, there should have the problem with above method which is calling every time for each Video
(I mean with next video).
Can anyone please suggest me.
