SKVideoNode奇怪的日志错误

Question

我按以下方式创建SKVideoNode。它创建视频没有任何问题，但我得到这个奇怪的日志消息，我想知道是否有人知道它是什么。我试过谷歌搜索，但我找不到任何东西。

这里出现错误：
[22:48:15.170] vtFindDynamicSession signalled err=-11204 (err) (registered pixel transfer service failed to open; falling back) at /SourceCache/CoreMedia_frameworks/CoreMedia-1562.240/Sources/VideoToolbox/VTPixelTransferSession.c line 6878
