我在Mac上尝试hls流媒体 . 对于某些内容，播放不会到达结束，AVPlayer在播放剩余1分钟左右发送AVPlayerItemFailedToPlayToEndTimeNotification信号 . 它总是在同一时间发生 .

AVPlayer获取播放列表，起始段= 100 . 它在18分钟的视频中播放约16分钟 . 然后它失败了AVPlayerItemFailedToPlayToEndTimeNotification .

这是AVPlayerItem错误日志

在错误日志中，它抱怨16分钟前播放的段100 . 它看起来像它的旧错误信息 .

这是播放失败时的访问日志信息

我已经比较了播放失败时AVPlayerItem的访问日志与播放是否正常（播放暂停时转储状态），唯一值得注意的差异是c-reason字段，如果失败则为1，如果成功，则为1 .

What is c-reason field and where can I get more information on that . AVPlayerItemAccessLogEvent没有说什么 .

以下是失败和成功案例的AVPlayerItemAccessLogEvent字段的比较 . 第一个值是失败案例，第二个值是成功案例 .

我知道它的长期问题，但如果有人可以检查上面的差异让我知道为什么玩家失败 .

感谢您阅读这个长期的问题 .

问候，D
