ios - seekToTime 不适用于 iOS 9 中的实时 Assets

Question

在播放实时视频时，SeekToTime 方法在 iOS 9 中不起作用。即使在搜索之后，视频也不会从搜索的位置播放。在以前的 iOS 版本中，它工作正常。以下是代码...

-(void)loadVideo{

[player pause];
player = nil;

asset = [AVAsset assetWithURL:[NSURL URLWithString:@"http://playertest.longtailvideo.com/adaptive/wowzaid3/playlist.m3u8"]];
playerItem = [AVPlayerItem playerItemWithAsset:asset];
player = [AVPlayer playerWithPlayerItem:playerItem];

AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = CGRectMake(20, 0, 600, 400);
[self.view.layer addSublayer:playerLayer];
[player play];

[self addPlayerTimeObserver];

-(IBAction)SeekToTimeInVideo:(id)发件人{ [播放器暂停];

[self.player seekToTime:CMTimeMakeWithSeconds(10.0, 25.0) toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero completionHandler:^(BOOL finished)
{
    [player play];

}];

有什么想法吗？？这是 iOS 9 中的错误吗？

Answer 1

刚遇到这个问题。我看到的情况是，如果 AVPlayer 在您调用 -[AVPlayer seekToTime:] 时暂停，播放器将跳转到最近的 HLS 片段的末尾。

我的解决方案是在调用 -[AVPlayer seekToTime:] 之前调用 [player play] ...这个:

[self.player play]
[self.player seekToTime:CMTimeMakeWithSeconds(10.0, 25.0) toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero completionHandler:^(BOOL finished)
{
    [player play];
}];
