Intel Core i7-1165G7 with Intel Iris Xe Graphics and a Nvidia GeForce RTX2060 failing hardware encoding

[aat]

Continuing the discussion from PMS has stopped doing hardware transcoding on Intel UHD 630:

Server Version#: 1.25.8.5621
Player Version#: Plex for iOS v8

I wanted to start a new post to see if anyone has seen anything similar. When plugging a monitor into my thunderbolt port and having that as my primary display hardware transcoding started to fail with an error of
Mar 17, 2022 20:25:17.019 [6280] ERROR - [Transcoder] [h264_qsv @ 0252e680] Error initializing an internal MFX session: unsupported (-3)
Mar 17, 2022 20:25:17.019 [6280] ERROR - [Transcoder] Error initializing output stream 0:0 – Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Following the steps in How to use integrated graphics for Plex transcoding – erik.ellsinger.me it now works again. However Windows still says Plex Transcoder is using GPU 1 (RTX) but windows shows both GPU’s in use. Is that common? Can I tell which GPU is actually used?

Can I tell which GPU is actually used?

I can’t help with system setup.

However, for which GPU is in use, look in Plex Media Server.log files for lines with TPU::
Mar 17, 2022 21:38:31.949 [11116] DEBUG - [Transcode/92F5D8AB-8E4E-45D1-87FE-F4F8BF77E006] TPU: hardware transcoding: final decoder: nvdec, final encoder: qsv

Decoding with Nvidia.
Encoding with Intel QuickSync.

Oh interesting, that explains why both GPU’s show activity. Thank you.
