Weird playback issue

[TheDreadPirate]

It is failing to initialize the GPU.  Did you install all the Intel drivers?  The official docker image has them built in, but you need to install them when running bare metal.

Hey, thanks for the input! I verified that the drivers were installed, and restarted everything. However, I'm still getting the exact same problem and the same error in the logs. What's weird is that despite QSV being selected, the error log is saying it couldn't initialize VAAPI. Additionally, this only happens with HEVC content (and some HEVC content does work for whatever reason). Everything else does work. Finally, as I said in the original post, this seems to only be happening on the Windows client, regardless of if I'm transcoding or doing direct playback.

What is the output of 

sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128

and

sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=vadev/dri/renderD128 -init_hw_device opencl@va -init_hw_device qsv
