I am having a similar issue, I checked OP’s logs and I have these same errors in the same type of configuration. I started a discussion on this reddit thread, moving here for additional support:
[Transcoder] [Parsed_hwmap_2 @ 0x1af5240] Failed to created derived device context: -19.
[Transcoder] [Parsed_hwmap_2 @ 0x1af5240] Failed to configure output pad on Parsed_hwmap_2
[Transcoder] Failed to inject frame into filter network: No such device
Jobs: '/usr/lib/plexmediaserver/Plex Transcoder' exit code for process 8484 is 1 (failure)
I have a Coffee Lake and HW Transcoding is failing on tone mapped jobs. Looks like Beignet isn’t working for Coffee Lake GPUs yet. There is a blog post from 2018 describing the issue with the driver and that it would be fixed in an as of yet unreleased version 1.4 (the latest being 1.3.2 from 3 years ago, https://phoronix.com/scan.php?page=news_item&px=Coffee-Lake-In-Beignet).

Hey I’m using a Comet Lake (10th Gen) CPU on Unraid (v6.9.0 beta35) via the official plexinc/pms-docker docker image.
I’m getting the following error in log when 4K HDR content is being transcoded:
beignet-opencl-icd: no supported GPU found, this is probably the wrong opencl-icd package for this hardware

@DaveBinM Can you please provide steps to get this working on Synology NAS? Give PLEX application available DMS Manager, I can’t install the ocl-icd-libopencl1 beignet-opencl-icd packages manually.
As mentioned in our support article, it depends on the drivers being available for the platform. However, you may have more luck running PMS in a docker container on your NAS, where we can include the drivers in the container.
@DaveBinM Much appreciated. I got a huge movies lib with over 85GB data folder. All are saved in Synology NAS PLEX folder. If I run the docker container… how to use the same data folders?
Thanks @DaveBinM. Just to be clear… given Synology PLEX app provided by PLEX, You guys are not going to release the updated version to the Synology DMS platform?
Just want to be sure…
P.S: I can see 1940785 downloads of PLEX Synology APP and I think it’s not fair to abandon these PLEX users.
We will most definitely continue to update the Plex Media Server app on Synology, but that doesn’t help with system level drivers that are required for this feature
you should read in docker mount options, its pretty simple to add a existing volume into the docker mount points, afaik your DSM even has a GUI therefore.
and about your 85 GB movie collection, you sure you need this feature due HDR movies are pretty big in size, lets say it like this, a remux 4k hevc has ~ 50 - 80 GB, 1 Movie …
and does your NAS really has a GPU to use it, intel coffee lake ++ ? or a nvidia gpu ? if so its worthe the effort, otherwise it ll be software transcode only and your NAS will be pretty stressed then … to narrow it down, it ll probably never come to a min 1x + encoding which you need for watching fluid.
just as note before you get stressed with dockers and so on …
