Server Version#: 1.30.1.6562
Player Version#: most-recent Windows Player (not Store version… not sure where the Player v# is located)
I moved my PMS to a new Windows-based server (server specs below). At home, I don’t seem to get HW transcoding for any file, HEVC/H.265/H.264, etc. I’ve also included some of the PMS log below, which I believe shows that HW transcoding is not being used for any movie file.
Media plays very well on 4k-capable devices, but when transcoding is needed on H.265 or H.264 files, it hangs with an error message that the server is not powerful enough.
- I’m NOT Running Plex as a service on Windows
- NOT running it in a Virtual machine
- NOT running it in a Docker container
I’ve reviewed several threads, such as below, but it seems this is for Linux systems.

Please confirm… What may be happening?
