about play back the video with ACC audio on the lag problem

[Zephylaci]

About I observed a phenomenon，transcoding will be triggered when audio in ACC format is present, and it will be stuck，but jellyfin web and external mpv there won't be that problem

I tried an external MPV but it doesn't help this situation

for example： This kind of video have lag

this one doesn't

use mpv no problem at all like this

but use jellyfin-mpv-shim have lag.. like this

What should I do？
