Yes, that has always been the case.
THANK YOU.
In case no one has mentioned it to the QNAP and the PLEX support staff thank you all. You are doing a hell of a great job. Thank you for supporting the community throughout the years. I donāt think these companies would have lasted this long without that quality support staff nor the community in continuing to buy their products without this support staff.
ā¦And the world would be a different place without your products. Weād have been extremely bored out of our minds and doing unspeakable things just to keep being entertainedā¦

Mine found meteorlake and not Arrowlake? Im on Intel Core Ultra9 285T

When I check Plex Dashboard - I see (hw) transcoding . Tried 4 x 4K movies and it was running perfectly .
Though sudo vainfo gives me errors? :

error: can't connect to X server!

So everything seems to be running fine - just curious if im missing something here.
I experienced the HW transcoding regression on Arrow Lake as well (Intel Ultra 9 285H + Arc 140T iGPU).
Public to Beta release fixed it : 1.43.1.10611-1e34174b1 ā 1.43.2.10687-563d026ea
Same with me. plexinc/pms-docker:1.42.2.10156-f737b826c works, anything past that transcoding is broken. Mine is a Intel Cometlake though.
Atomatth has raised an āissueā for me after I gave him my logs etc, not sure how to track progress tho.
@chris_decker08 HDR-to-SDR transcodes are continuing to fail to hardware transcode on my Tiger Lake machineā¦
Using the test build version 1.43.2.10623, CLDriver="icrl", running in unprivileged Proxmox LXC.
HDR-to-HDR transcodes utilize HW transcoding just fine.
EDIT: Realized my logs arenāt verboseā¦ Will re-test tomorrow when I donāt have to kick someone else off the server to get what youāre after.
Debug not verbose, please.
Here you goā¦
Did a fresh reboot on my Plex LXCā¦
Then, Equalizer 3, playing on a Chromecast attached to an SDR TV, resulting in an HDR to SDR tonemapped transcode. Plex fails to HW transcode, and falls back to software transcoding:

So, I donāt want to be an ass, but this bug was reported 2 months ago - seems like itās a pretty significant issue. Canāt really understand how have we not received an update yet. Especially that this is a paid feature.
It is fixed for a majority of users in 1.43.2 and we have so far been unable to replicate the various issues being experienced by the rest of users.
Any idea when this is going to be pushed to Public release?
@LostElric funny you should mention thatā¦
