PMS doesn't utilize Intel iGPU (UHD Graphics 630, CoffeLake)

Plex Media Server

Server Version#: 1.41.3.9314
Player Version#: Same issue on all players. Android Mobile, LG WebOS, ShieldTV…

Hi There,
I have the issue, that PMS which is running in a docker compose environment on QNAP TVS-672X with i5 8400T ignores my iGPU.

devices:
- /dev/dri:/dev/dri

is mounted in Docker-Compose YAML file and my GPU is also available and selectable in PMS Transcoder Settings.
But if plex must transcode videos it only utilizes CPU but not the iGPU, which I can see with intel_gpu_top inside pms container.

I found some log lines in Plex Media Server.log

Unfortunately my container always takes some seconds after startup to get a proper network connection. We can see in the log, that PMS tries to download the Intel driver, but fails, because the internet connection isn’t up yet.

Is there a possibility to reload this drivers manually?

Looks like that container has trouble to resolve the host plex.tv — so you might have a problem in the network configuration.

Yes, i know there is a network glitch, which I’m not able to resolve for the moment.
After the container is startet plex tries instantly to download that drivers. But the container network needs some seconds to initialize. ATM I’ve no idea why. There is no high CPU usage on the container host and the I5 CPU should be more than strong enough to handle that.

For the moment I’m a step farther.

I can see the plex tries to create a hw context to iGPU but fails.

Strange… I can see that coffee Lake QuickSync should be able to transcode H265 up to 10bit as I you can find here →

FYI, I was able to fix mit iGPU problem.
It was a permission issue on /dev/dri/renderD128 on the container host (QNAP). I mounted the this device into the container, I was able to see the device and also intel_gpu_top was working. But plex wasn’t allowed to utilize the device. My quick fix is to perform a chmod 777 /dev/dri/renderD128
After that plex can use the device as it should and CPU hit is much less than before. Also a live transcode of a 4K movie works as expected again.
