I5 9600k / Intel UHD 630 / Ubuntu 18.10 / Hardware Acceleration Not Working

Plex Media Server Desktops & Laptops

@ChuckPa so I just updated to Ubuntu 19.04 Beta. Good news it recognizes the iGPU!

However still no hardware transcoding in Plex. Do we need to wait for an update to Plex as well to support this?

Great idea! I just updated to Ubuntu 19.04 kernel 5.0.0-8. The Kernel recognizes the Intel UHD 630 now. However Plex still wonā€™t do Hardware acceleration.

23

Well, now itā€™s time to look at the logs.
Debug on Verbose off
Save and restart Plex
Play something that transcodes, wait 30 seconds and use the download logs under troubleshooting to make the zip file to upload.

24

Here is a snippet of the error. Also full logs attached.

Unfortunately there is nothing which I can report to look at regarding Ubuntu 19.04 beta. Between the end of any OS beta and the first set of updates, a LOT of changes are going to happen. We really canā€™t look at anything until itā€™s known stable. (like climbing onto speeding trainā€¦ almost impossible :wink: )

26

Darn it I shouldnā€™t have told you :wink:

I did include the snippet from the logs of the error in the above post.

27

I would have looked at your logs and seen the truth anyway :stuck_out_tongue:
:joy:

i have alerted the team. No reply yet but suspect they already know about iHD drv

28

Are you using the shell script ā€œtranscoder2.shā€ to enable nvenc?

29

This isnā€™t an nVidia issue. This is an Intel ASIC initialization issue in VA-API

30

No I am not. I do not have an NVIDIA card. Just Intel UHD 630.

31

Unusual to see it try libcuda before libva.

I was concerned that Ubuntu 19 has Application Permission Control would somehow block Plex.

32

All the recent versions look for the nVidia encoder first. I donā€™t understand why either.

33

@ChuckPa

I have installed Ubuntu 19.04 and still having issues with Hardware Transcoding. Is there anything I can do?

NOT surprised 19.04 isnā€™t working.

It was just released. No updates yet. Iā€™m working through issues I see with it already.
I am not yet convinced which are PMS bugs and which are 19.04 bugs.

I will continue to try but if it works on 18.04, you pretty much have the definitive answer

I know Intel has migrated to a new driver. The i965 is considered deprecated now. The iHD driver is now their preferred method of access. The upcoming transcoder update is (I hope) supposed to include that driver.

35

@ChuckPa I am seeing the same set of errors but on Ubuntu 18.04. Iā€™ve been running Plex on my Synology for years but finally caved and bought a dedicated server with some more ooomf. I followed your Synology->Linux transition guide and it worked flawlessly. The only thing is now HW transcoding seems to be broken. I am running an i9-9900K so it definitely has QuickSync. Iā€™m assuming this should be working on 18.04 though correct? I see the following errors in my Plex Media Server logs:

Apr 22, 2019 00:40:53.902 [0x7f986ffff700] ERROR - [FFMPEG] - Cannot load libcuda.so.1

Apr 22, 2019 00:40:53.903 [0x7f986ffff700] ERROR - [FFMPEG] - Failed to initialise VAAPI connection: -1 (unknown libva error).

Any ideas? I can upload additional logs if needed.

It didnā€™t work on 18.04 as there was an issue with Plex and the Linux Drivers for the 9th Generation Intel GPU. 19.04 that is solved with the new Kernel. However it appears that Plex doesnā€™t do something to use the new drivers.

I bought a new server just to run Plex with an i5 9th generation and I am hoping Plex can fix the driver issue so this purchase wasnā€™t a waste of money.

Pretty please!

37

@dalnew It didnt work on 18.04 or 18.10 as the new 9th generation iGPUā€™s were not supported. They are supported in 19.04. It looks like Plex needs to do something to use the new drivers.

38

To all reading here:

The new family of drivers which Intel has transitioned to are being worked on by Engineering.

There is nothing further to report at the time.

39

YAY! @ChuckPa appreciate the hard work!

40

Is the expectation that this will be worked out for 18.04 or will I need to migrate to a newer Ubuntu release for this support? Iā€™m just trying to figure out if I should put any more work into configuring my 18.04 box or scrap it and move to a newer build.
