[Bug]: Hardware video acceleration not working properly

[pojlFDlxCOvZ4Kg8y1l4]

Which component impacted?

Decode, Not sure

Is it regression? Good in old configuration?

No, this issue exist a long time

What happened?

Using HEVC hardware transcoding with jellyfin results in a bad picture.
The CPU is a Intel Celeron J4105.

Using software transcoding, direct play works fine.
Also VP8, VP9 and x264 hardware transcoding results in good picture with a little higher than expected CPU utilization.

Examples of the bad quality:

Big_Buck_Bunny_1080_10s_30MB_X265_OUTPUT.mp4

The package maintainer thinks the drivers are problematic, which are also a guess from the jellyfin dev.
So here I am, hoping it is a easy and quick fix! :>

Link to the issue with the jellyfin github

What's the usage scenario when you are seeing the problem?

Transcode for media delivery

What impacted?

No response

looks it is an hevc encode issure? the artifacts is exist in output bitstream playback?,

I do not have a display attached, the weird output happens with different drivers.
There was a change in behavior with a different driver in the alexbelgium jellyfin add-on.
See this comment: alexbelgium/hassio-addons#537 (comment)

I've also run commands which other "jellyfin" users/devs mention to have no problems with.

I would like to refer to these two issues I've created at both alexbelgiums repo (jellyfin on home assistant add-on) which bases off the linuxserver.io add-on, which in turn uses jellyfin from the jellyfin repo.
These people have tried to troubleshoot me, there's also multiple commands listed which I've tried but did not solve the issue.

Do you need further information or maybe clarifications from the other issues?
