HEVC playback error in the Desktop App

[LordByron_]

Hello,

My Jellyfin instance was running smoothly for quite some time now. Last week I noticed, that every HEVC video I try to start in the Jellyfin Desktop App just gives me an error:
Playback failed with error "loading failed". Retry with transcode? (Note this may hang the player.)
PlaybackError.mediadecodeerror

This only happens when I access Jellyfin externally through an Apache2 reverse proxy. If I tunnel my traffic through SSH, it works without any problem.

Did maybe someone else encounter this at some point?

Thank you in advance

Can you share your jellyfin logs via pastebin?

Can you share your jellyfin logs via pastebin?

Which logs do you mean? Just the one from /config/log?

[TheDreadPirate]

Yes. /config/log/log_20240905.log

[LordByron_]

Yes.  /config/log/log_20240905.log

Here you go: https://pastebin.com/h4LLinqD
I may need to enable some debug options, because that log doesn't seem to be that helpful.

Are all your HEVC files also HDR? What are the specs of the PC running Jellyfin Media Player?

Do you have a maximum bit rate setting for remote clients?

The PC running the Media Player has a HDR Monitor connected and these specs:
Ryzen 7 5800x3d
4070Ti
32gb ram
M.2 SSDs as storage

The error only comes up if I try to play files with a bitrate over 40Mbit/s, but I don't know where I can change the limit.

In JMP, click on your profile picture in the top right > Playback > Internet quality. Set to 60Mbps. Not sure if "auto" will allow for higher values. It is also possible "auto" is the problem and incorrectly detecting your network speed.

Thank you very much, this worked. I wasn't able to find this setting, because you can only access it, if you have the permission to transcode video. Is there a way to change that behavior?
