I have a few files like this, but in this case, playing “Liar Liar” will have the client side buffering endlessly. No error message gets displayed. I don’t have reason to believe it’s transcode related because the problem is replicated regardless what HW transcode is set to.
Ideas?
Logs posted.

You’re getting SW transcode even though PMS sees the AMD.
There is a limitation right now with this first release of AMD support – NO HDR.
If you have HDR enabled, HW transcoding fails and it stays SW.
Might be the case given I see no HW being used in the FFMPEG command line?
Hmm when I ffprobe the file in question, it returns a colour space of “YUV” and a bit depth of 8 bits. This leads me to believe the source file is not HDR.
It is H.264 so BT709 8 bit

Stupid question time – Is the Plex user a member of the group which owns /dev/dri/renderD12* ?
This is TrueNAS, so it’s operating within a kubernetes pod.
Short answer - yes, the plex user is part of the group “video” and “video1” who has ownership of /dev/dri/renderD128.
root@truenas:/dev/dri# ls -l
total 0
crw-rw---- 1 root video 226, 0 Aug 7 20:06 card0
crw-rw-rw- 1 root video1 226, 128 Aug 7 20:06 renderD128

renderD12 ?? NEVER saw that before.
The Linux kernel starts enumerating at minor number 128 and that’s the name given to the renderDxxx.
PMS looks for renderD128 at minimum. Did you make a typo in the container passthrough definition ?
Kubernetes is not tested. PMS operation not guaranteed.
This is how /dev/dri should be:

On closer inspection it is indeed renderD128. My copy paste must have cut off the last digit. Apologies for that.
Bumping this to update with a little more trouble detail. It turns out my issue is transcode is just not working at all…whether it be software or hardware. Turning off hw transcode yields the same results.
