SOLVED: Jellyfin does not trancscode 4K HEVC in web player

[bioblatt]

update, I'm now on kernel 6.9.7+bpo-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.9.7-1~bpo12+1 (2024-07-03) x86_64 GNU/Linux
and jellyfin 10.9.9 but the problem still occurs. My server can't transcode any 4K HEVC content via the web player using Firefox or on some devices in the Android Jellyfin app with the default player.

[bioblatt]

also upgrading to debian sid (6.10.3-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.10.3-1 (2024-08-04) x86_64 GNU/Linux) has not solved the issue

[TheDreadPirate]

Can you share some logs from these latest attempts?

[TheDreadPirate]

Oh. And screenshots of Dashboard > Playback. You haven't shared any since the first page of this thread.

Sure here's everything:

The movie plays fine in direct play on the Windows Jellyfin Media Player and my LG TV, so there's nothing wrong with the file.
1080p HDR and SDR HEVC transcodes, it's only 4K HDR HEVC that's not working.

[TheDreadPirate]

On both Firefox and your Android phone (when using the web player), do they work when you set a max transcode resolution? I'm assuming neither of them are on 4K displays. I know that some users had issues with the Android web player when the transcoded video was 4K. But Firefox shouldn't have a problem with that.

Either way. Try setting Settings > Playback (not the one in the dashboard) > Maximum Allowed Video Transcoding Resolution to 1080P.

[bioblatt]

Still the same outcome for Firefox and Android using the web player.
I tried Auto, 1080P and Screen Resolution with "Limit maximum supported video resolution" disabled/enabled.

Just noticed this.

[bioblatt]

Uninstalled the plugin. 4K HEVC transcodes.
I feel soooo stupid now...

Sorry for all the efforts of the past days/weeks. I thought the plugin does something completely different.

Thank you so much for all the help!

This makes now completely sense why it sometimes showed a split second of transcoded video.
