Server Version#: PMS version 1.30.0.6406
Player Version#: Various <4kHDR capable clients
Could use some guidance/suggestions— I can’t transcode HDR content on my PMS for nothing… direct play clients work fine and HW acceleration works fine for SDR content— but anything that has to transcode HDR and forget it. May play for the initial 30 seconds but then buffers until it eventually errors out saying server isn’t powerful enough.
PMS specs below. Lifetime PlexPass owner here. The server is a bit older hardware but it’s 100% dedicated to PMS and I would think it wouldn’t have any problem with this but here I am… anyone have any guidance? Much appreciated!
PMS version 1.30.0.6406
Windows 10 Pro 64bit
NVIDIA GTX 1060 (Driver version 526.98)
Intel i5 4440S (4core 2.8GHz)
8GB DDR3
OS Drive (where Plex runs from) EVO 850 SSD
Media Drives where media is stored are 7200rpm WD hybrid drives
[edit1]One additional note— as a comparison troubleshooting, I loaded up an emby server instance and installed the emby client app on a client and it handles the transcoding just fine. Not that I like or want emby— just mentioning it as a reference point. Seems the hardware can clearly handle the transcoding. Just not when PMS is doing it with how it’s currently configured.

[edit2]Another additional note-- This happens regardless of subtitle usage. With or without subtitles.[/edit2]
Well shoot-- after messing around & for $#!T$ and giggles I tried unchecking the HDR Tone Mapping feature and sure enough-- it’s now transcoding (hw) just fine… which lead me to search a little deeper in the forums to find that HDR Tone Mapping isn’t even supported in Windows with NVIDIA! HDR to SDR Tone Mapping | Plex Support
Anyone know if/when this feature will be available?
If you’ve not done so, download the install the 64-bit version of Plex Media Server. The installer will detect and remove the 32-bit version. This is only for the PMS application. Your media, the Plex database, etc are not touched during the installation.
It supports zero-copy transcoding on Nvidia GPUs, which reduces the amount of data moved between the GPU RAM and system RAM and increases transcoding performance.
This has enabled some users to take advantage of HDR to SDR tonemapping on Windows based systems.
Appreciate the response. I read another post suggestion this (may have even been yours) before I posted but I thought to myself “of course I have the 64bit version already installed”… apparently I didn’t. Went and downloaded/installed and it’s able to transcode with the tone mapping feature enabled. Thanks.
I am trying to understand what you meant here. Did you mean that this enabled hardware accelerated HDR tone mapping on Windows? Or by saying “some users” you meant that it somehow made it easier for the CPU to do the tone mapping. Right now I have an i5-7600 with Intel 630 graphics and it can’t do 4K HDR to 1080p SDR tone mapping. I wonder if adding a GTX1650 will make it happen on Windows. I am exploring possible ways before moving to Linux.
