Thanks for the info. It appears to me they are solving an issue where hw encoding doesn’t work while using RDP. Isn’t it the opposite for us?
I regard disabling RDP hardware acceleration more like a workaround and detrimental for accessing the server. Running Plex as a service also complicates updating significantly. If possible, I’d rather have Plex just working as expected. Jellyfin works fine with QSV btw, no RDP changes required.
If there is no other way, I’ll install it as a service and/or tinker with the RDP settings, but for me this appears more like a Plex issue.
It appears to be that windows sees a new monitor attached to an nvidia graphics card as a separate GPU. When combined with the fact that windows sees an rdp session as a new monitor it messes with PMS’ cache of gpu devices. If you start PMS without RDP and then try to transcode is it successful?
Yes, if I exit PMS via RDP, then after closing RDP run PMS via SSH, select the Intel GPU in Transcoder settings it also does Hardware Transcoding fine.
I’m very confused about why and if this should be HW transcoding. I’m on a 13500, windows 10, downloaded the preview and may or may not have updated once I found out that 13 series wasn’t compatible. I can’t remember but I’m on 1.40.1.8190 regardless. Yet, I see this.
What made you think that?
13th Gen is very recent and therefore supported.
Because Raptor Lake isn’t listed as compatible, and several people have said throughout this thread that ONLY the ones listed work. Namely 11th and 12th gen. Also, DV has failed to transcode, yet this HDR10 file did.
Raptor Lake is 13th and 14th generation.
Alder Lake is 12th generation and is listed as supported above. And it says “and All Future platforms…”
Video with only DoVi data (i.e. without HDR10 compatibility data) will not be transcoded/tone mapped, because there is no license in Plex for DoVi.
Interesting. I think a lot of people were confused on the compatibility since the OP was very specific on compatible architectures, but I didn’t know about the DV thing, so I’ll be sure to stick with HDR/HDR10 files in the future.
So if I have a DoVi/HDR file and the user has DoVi capability, but tries to lower the playback bitrate, does it try to transcode DoVi—>SDR, or does it fallback to HDR/HDR10 and transcode that?
I’ve got what I believe is a supported CPU: “ 12th Gen Intel i5-12450H NUC12”. The max amount of HW transcodes is about two. I’m pretty sure that my CPU is more capable than just two HW transcodes is there something else that needs to be turned on in conjunction besides beta updates, latest intel drivers and turning on HDR tone remapping?
works well with an a750, but the tonemapped SDR image is really dark, any way to adjust that?
Unfortunately intel provides no way to adjust the darkness (I personally also think its too dark). This is a well known issue (our competitors also see it when tone mapping via qsv), so I’m hoping intel either fixes it internally or exposes the ability for us to tweak it.

I’m still getting near constant buffering if I try to play 4K files that work fine on my LAN; no problems with 1080p sources
With an Intel N95 on the latest version posted (1.40.8190), I couldn’t get hardware transcoding to work at all with multiple videos, tried installing the PMS service, tried the fix here https://forums.plex.tv/t/windows-remote-desktop-breaks-hw-transcoding-qsv-heres-the-fix/776428.
Just ended up reverting to the public version.
@kleatus27 are you able to send me your logs from the failed attempts? also, are you starting utilizing RDP in conjunction with PMS?

Mulan claimed to be hardware transcoding, Avengers didn’t, and I think Survivor also failed to hardware transcode.
It’s the same during RDP or not, this is all without HDR tone mapping enabled.
Hardware transcoding working fine with everything I’ve seen on the public version.
If you restart pms then start playback without any sort of RDP session initiated, does it still give an error?
I haven’t looked at the logs myself but restarting the PC and using Plex before ever starting an RDP session yields the same result, that Avengers file resorts to software transcoding.
Let me know if I can be of help with testing, very interested in getting this working on my machine, it’s not really powerful enough to do software HDR tone mapping.
