这些是文件

文件没有以任何方式损坏（检查重新下载并检查哈希）
当我启动 vlc 并拖放文件时，一切正常，但字幕非常不同步
Dialogue: 0,0:00:11.08,0:00:12.61,Default,Tsujii,0000,0000,0000,,We've gotta get out of here!
第一个对话发生在电影文件中的 1:41
我需要 90 秒的延迟，因此应用了设置 (+90.0) 从Tools > Track Synchronization > Subtitle Track Synchronization
但在那之后，对话根本没有出现
我将延迟降低到 +5.0，正如预期的那样，对话出现在 16 秒。我将它增加到+10.0，它仍然有效。但是 +20.0 不起作用。诡异的！
然后我在终端启动 vlc 看看是否有任何错误。这是输出
$ vlc "Another 12.mkv"

我认为这可能是内存损坏或其他原因，但我什么都看不到，所有其他应用程序都可以正常工作，除了 vlc 有时会冻结。
有人知道发生了什么吗？
