Hardware HDR transcode with PMS 1.28.1.6018 inside docker stopped working

Plex Media Server
1

I updated to the latest PMS beta ( 1.28.1.6018) today amd noticed the release notes had a lot of changes around HDR support. Attempted a transcode of a 4K HDR10 file and hardware transcoding didn’t start as it had been with the previous version, downgraded and verified HW transcoding still worked.

Taking a look at the Dockerfile on pms-docker/Dockerfile at master · plexinc/pms-docker · GitHub it was using pretty old versions of the necessary intel libraries. I pulled that repo updated the versions, rebuilt the container and hardware transcoding started working again with 1.28.1.6018. Thinking there may be some incompatibility between the recent changes and the versions of the libs included in the docker image.

My CPU is an Intel Core i9-9900K.

Same here, reported on this thread

Latest Plex beta (1.28.1.6041-738907df3) still have the issue

Hardware HDR transcode seems to be working again with 1.29.0.6209-9fa696df6 and the latest intel drivers.

Can you please provide the version number on the intel drivers for comparison purposes? Thanks!
