When using video.js to play m3u8 videos, there is sound but the video does not play, only showing the first frame.

[ilaziness]

OS is Linux Mint 22.

When I pause, the current frame is displayed.When continuing to play, the video still does not move.

During playback, when I drag the progress bar to fast-forward, the video plays normally and does not get stuck on a single frame.

What is the issue?
