ios - seekToTime在iOS 9中不适用于实时 Assets

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，视频也不会从搜索位置播放。
在以前的iOS版本中，它可以正常工作。
以下是代码...

-(无效)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)sender {
[玩家暂停]；

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

}];

}

任何的想法 ？？这是iOS 9中的错误吗？

最佳答案

刚刚也遇到了这个问题。我看到的情况是，当您调用-[AVPlayer seekToTime:]时，如果AVPlayer暂停了，播放器将跳至最近的HLS段的末尾。

我的解决方案是在调用[player play]之前立即调用-[AVPlayer seekToTime:] ...因此，您将获得以下信息:

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