Hardware transcoding not working in docker

Plex Media Server
,

I just installed PMS on the host. Hardware transcoding still fails.

PlexMediaServer install: PlexMediaServer-1.30.1.6497-5fc2e0894 - Installation starting.
PlexMediaServer install:

I’m here.

That looks good.

Show me /tmp/plexinstaller.log please (wrapped in </> code markers)

excellent.

now cross confirm.

groups plex

Compare that to the GID which owns /dev/dri/renderD128

Do you have a small library section (maybe some home / test videos) you can verify HW transcoding works?

If so,

Settings - Server - Transcoder - Show Advanced.

Make certain all the transcoder options are enabled (I’ve see that mess up for some)
SAVE if you make changes.

Now try HW transcode.

27

I am connected to his NUC over ssh. Can I verify those settings on the console?

28

SSH Tunnel to it.

On your machine:

  1. ssh -L 8888:127.0.0.1:32400 ip.addr.of.remote
  2. Log in and let sit idle
  3. Return to the local host
  4. Open a browser tab to http://127.0.0.1:8888/web

It’ll run through the tunnel.

This is my friend’s Plex server not mine. Doing that asks me to authenticate to Plex for MY server.

Are these settings stored in a config file on the host?

30

Preferences.xml stores the server ownership info

I am looking at my NUC that works and I see this

I see these errors

[h264 @ 0x7f5d5c6c8100] missing picture in access unit with size 10

Don’t these point to another cause?

32

So the transcoder settings are not stored anywhere on the host? They are stored on Plex servers?

33

Transcoder settings are in the DB.
Owner is in Preferences.

Want a controlled, known good, test video?

34

Both files failed.

Based on the errors I am seeing, it looks like a driver issue. Doesn’t it?

35

Full PMS logs ZIP please ? I can’t debug fragments of this stuff.

It might be ICR libs or might be iHD. Impossible to guess.

36

@Tortuga

I went digging.

Give this a try.

echo "options i915 enable_guc=2" > /etc/modprobe.d/i915.conf

Update initramfs and restart (obviously)

37

I did that and ran update-initramfs -u

So now I get a whole set of new errors…

Do you still want the server logs?
