PMS 1.32.6+ HW transcoding issues and corrections. ALL: We’re really sorry. We missing a whopping fault in PMS. Specifically, we missed a change which broke HW tone mapping support on Linux platforms. ( that’s what I get for sleeping from 4am → 6am :man_facepalming: ) Where we’re at We’ve g…

Hi :hugs: There’s some news regarding HDR tone mapping support for Proxmox with a Plex LXC for Alder Lake. I’ve noticed that it’s not working on my new installation with an i9 12900H. The hw is working perfectly without mapping.

AMD Ryzen 3600, CPU transcoding. No GPU Where does the log[s] get saved? I May need to mount the log dir to get access from the host OS. I can try to get logs this week.
