我的 VLC (v2.0.6) 显示了许多不同的错误，例如这些
主音频输出警告：PTS 超出范围 [...] 掉线
和
主音频输出警告：计算的 PTS 超出范围 [...] 清除
这些错误会导致音频故障。PTS 代表什么？如何解决此错误？
这是我的日志的一部分，

看VideoLan 错误追踪器—— 这是谷歌上针对此错误信息搜索到的第二个结果。
您可能正在播放带有流的视频文件PES（封包基本流）。由于这些数据的设计限制，它们无法正确同步。因此，当您的视频以不规则的速率播放时，或者当专用硬件无法保持流同步时，软件会注意到（当为时已晚）它们不同步，并丢弃音频缓冲区中的帧以修复它。
几乎所有的图形驱动程序都会在帧速率中产生一些延迟或抖动，即使如此，驱动显示定时的压电石英晶体也无法与音频定时晶体完全匹配，因此，如果软件没有数据来使音频和视频与视频文件中的数据保持同步，就会遇到这样的问题。
请注意，有非常昂贵的硬件可能能够在硬件定时级别保持流同步，但这些系统通常用于工作室的制作团队。
