Hardware acceleration on Synology DS224+ - BrownCoat - 2023-11-24

Hi everyone,

I am new to NAS and Jellyfin and I'm having trouble getting HW acceleration to work on my DS224+.
I have Jellyfin installed through the Synlology Package Center, version: 10.8.12-12.

Here are my current settings under Dashboard -> Playback -> Transcoding:

I am trying to transcode this file:

The video seems to load indefinitely. CPU usage on the DS224+ goes to ~55%, but the video doesn't start playing.
I also tried transcoding a 1080p video to 720p which did start after some time, but it had very choppy playback. CPU usage was about 25%.
This happens both on local network and remotely.

Did I forget a setting? What can I do to fix this?

Thanks for the answer! However, I think my issues is (partially) caused by something else, as it happens with any file that is transcoded.

For example, a 1080p HEVC SDR (2.09 Mbps) file transcoded down to 480p (720 kbps) buffers, plays for 3 seconds and buffers again for 10+ seconds.
Another example, a 720p H264 SDR (649.86kbps) file transcodes by default to my Android phone. It plays, but there is a very noticable stutter every second where the audio cuts out and the video freezes.

This all happens with the Dashboard -> Playback -> "Enable VPP Tone mapping" and "Enable Tone Mapping" disabled.
What could be causing this?

What I heard only mentioned the Intel OpenCL driver, its also possible that the Intel Media driver (general QSV transcoding) also dropped 4.4.X support. What you are describing seems to back that up.

Oh snap, I see. That would mean that I basically don't have HW acceleration in this version of Jellyfin, correct?

I will try to downgrade to 10.8.11. Is there an easy way to do this, using the Package Center? Or should I look into how to use Docker for this?

Thanks for your help!

Just an FYI, the devs are aware of this issue and are discussing how to handle this with future docker images.

I found this thread on GitHub:
https://github.com/jellyfin/jellyfin/issues/10550

Did they decide to not resolve this issue due to the kernel being too old? Or am I misreading this thread?
