Question

我正在尝试在Mac上播放hls。对于某些内容，播放到达结束并且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，起始片段= 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。它看起来像是旧的错误信息。

以下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（暂停播放时转储状态），唯一值得注意的差异是c-reason字段，如果失败则为1， - 如果是成功。

什么是c-reason字段？在哪里可以获得有关的更多信息。 AVPlayerItemAccessLogEvent对此没有任何说法。

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述差异，请告诉我为什么玩家会失败。

感谢您阅读这个长期的问题。

AVPlayer发送AVPlayerItemFailedToPlayToEndTimeNotification并留下约1分钟的播放时间
