ios - AVPlayer 返回 nan 视频
<p><p>我正在尝试使用以下代码在 avplayer 上播放视频...但没有任何结果，因为它显示持续时间 nan。</p>
<pre><code>func setUpPlayer(fileURL:URL){
let playerItem:AVPlayerItem = AVPlayerItem(url: fileURL)
player = AVPlayer(playerItem: playerItem)
let playerLayer=AVPlayerLayer(player: player!)
playerLayer.frame=CGRect(x:self.videoContainer.frame.origin.x, y:self.videoContainer.frame.origin.y+20, width:self.videoContainer.frame.size.width, height:self.videoContainer.frame.size.height-40)
player?.addObserver(
self, forKeyPath:"currentItem", options:.initial, context:nil)
self.view.layer.addSublayer(playerLayer)
rangeSlider.setVideoURL(videoURL:fileURL)
rangeSlider.delegate = self
self.endTime = CMTimeGetSeconds((player?.currentItem?.duration)!)
let timeInterval: CMTime = CMTimeMakeWithSeconds(0.01, 100)
// let asset:AVURLAsset = AVURLAsset.init(url:videoURL)
// let videoDuration:CMTime = asset.duration;
//
//
// let timeInterval: CMTime = CMTimeMakeWithSeconds(videoDuration,100)
//CMTimeGetSeconds(videoDuration)
timeObserver = player?.addPeriodicTimeObserver(forInterval: timeInterval,
queue: DispatchQueue.main) { (elapsedTime: CMTime) -> Void in
self.observeTime(elapsedTime: elapsedTime)
} as AnyObject!
}
</code></pre>
<p>我是第一次这样做。请提供一些解决方案来解决这个问题。在此先感谢!</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>你错过了在你的代码中写“player.play()”</p>
<pre><code>let timeRange = self.avPlayer.currentItem.loadedTimeRanges.CMTimeRangeValue
let duration = CMTimeGetSeconds(timeRange.duration)
</code></pre>
<p>试试这个绝对有用</p></p>
