Cannot play H.264 10bit source video in browsers with the Chromium kernel.

Describe The Bug

Cannot play H.264 10bit source video in Chromuim kernel browsers, and there is no error popup diaglog or loading animation.
After discovering this issue, I reinstalled Jellyfin and deleted all configurations. I currently have no hardware acceleration enabled, yet the problem persists.

When I try to play this video, the log only add one line:

[13:56:28] [INF] [10] Jellyfin.Api.Helpers.MediaInfoHelper: User policy for admin. EnablePlaybackRemuxing: True EnableVideoPlaybackTranscoding: True EnableAudioPlaybackTranscoding: True

and then there is no further log. It’s as if the server completely ignored the client’s playback request.

The Windows client and the WebUI via Firefox do not have this issue.
