HW-Transcoding works cool with my Intel Pentium Silver J5005 at Debian 9 and Ubuntu Server 18.04. But it not works with Debian 10 for some reason. I know, it’s not released yet, but they already plan to release it in the end of July. I don’t think that there will many changes.

Server Version#: 1.16.0.1220
Player Version#: 3.102.0

Problem resolved: plex user wasn’t in render group, so didn’t has access. I guess devs should fix it in future releases.

Btw it’s sort of feature from Systemd 236 release.

Which devs?

Debian? I would hope so.

It looks like their udev module isn’t working right yet if it’s root:root

The package installer adds itself to the right group. That tells me udev isn’t triggering.

Please compare:
