真复现不了。。。同样的时间点 seek 也没出现，要不你在 src/avplayer/subtitle/SubtitleRender.ts 里面调试一下，看看是什么情况

[zhaohappy]

TypeError: Failed to execute 'decode' on 'TextDecoder': The provided ArrayBufferView value must not be shared.

好家伙，今天把 chrome 更新到 129，这个问题竟然偶现了。问题是已经判断是 ShareArraubuffer 不走进去，它又是怎么进去的 。。。

你再用官网的播放器测试一下，改了一版
