Unfortunately, this preview breaks hardware-accelerated transcoding for my Jasper Lake-based Celeron N5105 CPU, for at least some formats. Here’s the XML info for one example:

It falls back to software transcoding, but this CPU isn’t capable of transcoding 4K HDR10 media in real-time.
This same media transcodes using HW fine in the current beta release. I’d be happy to provide logs if you’d like @chris_decker08, just PM me. I can provide logs for both the working, current beta and forum preview here.
Here’s a link to the test file, if you need it:
@chris_decker08 , I tried to follow the guide to update my docker container to the latest version but it seems the plex_service.sh script doesn’t exist:
I tried searching for it like this:
root@abc:/# find / -path /mediathings -prune -o -name “plex_service.sh” -print
@Devedse Which docker image are you using (official, binhex, Linux server, etc)
Linux server one
I can’t find it in my binhex-plexpass either. I’m going to spin up an official Plex docker later tonight to try it out
Looks like it’s only in the official docker
So I couldn’t find that ‘plex_service.sh’ scirpt so I just created my own image using this github repo + changed the .deb url to the new one you posted:
I think it’s working on my Intel Arc Pro B50:

I have a dedicated XE-DG1 card (probably pretty rare), and the .deb on ubuntu 24.04 now gives HW Transcoding! As proved by intel_gpu_top (and the dashboard). woohoo!!
Tested out the build with my B580.
OS: unRAID 7.2.1
LinuxServer.io Docker Container
Used environment variables -
PLEX_DOWNLOAD=https://artifacts.plex.tv/plex-media-server-experimental
VERSION=1.43.1.10350-71a2c3fa9
Seemed to pull the build correctly and even used the B580 according to the logs but transcoding was extremely slow with constant buffering so I switched back as I was running out of time for testing.
If no one else has reported this and you need logs, let me know what I need to grab as I’d be more than glad to assist.

Exact same setup as rjwaters147 above, but with no slow transcoding/buffering issue.
Tested with 4x 1080p transcodes at the same time with no issues, skipping around and all with next to no delay.

server debug logs please which capture both PMS startup and the start of the playback ? (20 seconds worth will do)

working GREAT for me. Super snappy response. What I was hoping this B580 would do for my setup. Running official docker container on Fedora 43. Thanks!

I have to say this is working really well for me. I specified the download URL and I am using linuxserver.io’s Plex docker image. No issues to report as of now.

Recreated the issue and pulled the logs with debug enabled, let me know a secure way to share them as I cannot message you directly.

Check your PM.
The container is seeing the GPU when it probes the bus.

What should be happening?
If it should visibly be transcoding,
Would you please repeat the logs capture but use Plex/web for the playback AND set the playback bitrate to a lower value such that it forces a video transcode ?
Quick question for the Unraid crowd about the steps to get this set up.
I’m currently using linuxserver and am curious if the following steps are correct.
- change VERSION from “docker” to “1.43.1.10350-71a2c3fa9”4
- add a variable that contains the KEY “PLEX_DOWNLOAD” and Value “https://artifacts.plex.tv/plex-media-server-experimental”
- apply it and open plex settings
- change hardware transcoding device to the battlemage card.
Are there any steps I’m missing or anything i am doing wrong? I assume HEVC video encoding is not to be selected due to it being experimental?
Thanks!
Yes that’s right. I just switched from binhex-plexpass to linuxserver image and did exactly that and it immediately downloaded the beta release. Changed the transcode to device to the battlemage and it worked.. I turned on HEVC encoding and it’s working like a champ. Trying to see if I can find any files it won’t hardware transcode but everything is working great so far
