SOLVED: Force transcode to h265

[Gasico]

Hi guys, i am using Jellyfin Server version 10.8.13 installed on a Windows machine via Windows Installer.
I have a Celeron G5905 with Intel UHD 610 which should be able to handle H265 10-bit.
Most of my media files are UHD 10-bit HDR h265 on .mkv/mp4 containers.
The problem i'm having is that some of my friends can't direct play these files due to the very high bitrate and their poor connection so they are forced to get a lower bitrate version of the media file, however i can only get the server to transcode to h264, not h265 which should be better in my case considering that my friends can play h265 the problem is that their client aren't requesting a h265 transcode but only h264 (in my opinion it shoiuld be selectable into the client settings)
So the question is, can i somehow force the server to transcode to h265 instead of h264? like changing some profiles or something, what can i do to get a transcode to h265?

Setting Exoplayer as the "preferred media player" on the clients instead of libVLC should enable H265 transooding if the server can handle it. You maybe have to change "Audio output" to "downmix to stereo" on the client also, otherwise 7.1 files will fail to play at all.

The server doesn't determine the resulting codec entirely. It is a combination of what the client requests/can handle vs the server config. If the client never requests HEVC then the server won't send it.

What clients are you friends using?

I found that the Jellyfin Media Player client on Windows has a setting in Client Settings>Prefer_transcode_to_h265.

With that setting turned on, it works, the server is transcoding to h265, however the media just get stuck, it freezes with an infinite loading circle, here's the log of ffmpeg.

EDIT: i found that disabling "Enable Intel Low-Power H.265 hardware encoder" it just fixes this, so now everything is working, thank you so much!!

The low power setting is not supported by every GPU. If I'm reading our docs right, your iGPU only supports the low power encoding mode for H264 but not HEVC.
