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

Agster · April 2, 2019, 12:16am

Hardware:

*Intel Core i5-9600K Coffee Lake 3.7 GHz

*Intel UHD Graphics 630

*MSI B360M PRO-VH LGA 1151 mATX Intel Motherboard

Software:

*Ubuntu 18.10 - Desktop Minimal Install

*Plex 1.15.3.858 - Direct Install

I installed PMS on a brand spanking new Ubuntu build. I imported my old PMS database and library per Plex instructions and it’s working great!

HOWEVER… When PMs transcodes, for example when playing on my mobile phone over ATT LTE network, it does not use Hardware Acceleration.

I cannot for the life of me figure this out. I’ve looked on Reddit, these forums and cannot find a solution. Anyone have any ideas?

I’ve tried reinstalling the i965-va-driver and still doesn’t work. Please help! I know it’s something simple I am missing.

Your vainfo is saying the driver isn’t initialized.

What happens when you install xserver-xorg-video-intel.

ChuckPa · April 2, 2019, 3:27am

Ubuntu 18, “minimal” desktop install is more than enough.

Please verify “DEBUG” logging on, “VERBOSE” off.
Settings - Server - Transcoder - Show Advanced - verify “Use Hardware Acceleration when available” is checked. - Save changes
Start playback
Play 30 seconds
Stop Playback
Settings - Server - Troubleshooting - Download Logs
Attach the ZIP file it gives you

Agster · April 2, 2019, 12:21pm

Attached is the zip file! Any help would be apperciated!

*Turned Debug on and made sure verbose off
*“Use Hardware Acceleration” is turned on

Thank you for the logs.

The logs show the kernel does not yet recognize the -9600k. They also show Plex attempting to find nVidia and not finding it either.

Agster · April 2, 2019, 3:15pm

That makes sense. So in summary I need a kernel update ( when one is available ) to recognize the 9600k?

ChuckPa · April 2, 2019, 3:33pm

That’s correct. The kernel itself must first recognize the internal i915. The i965 driver talks to the i965 which in turn returns i915 information. We see the i965 getting unrecognized replies from the i915.

saltydk · April 2, 2019, 4:46pm

Even with a working driver Plex will not be able to use HW transcoding till you lads fix this:

ChuckPa · April 2, 2019, 5:01pm

Knapsu does a fine job of building a version of PMP. Relevance here? I’m not sure with of the multiple points being referenced applies.

saltydk · April 2, 2019, 5:14pm

The relevance is that you are trying to use a driver that is deprecated, no?

ChuckPa · April 2, 2019, 5:22pm

The driver is maintained and provided by Intel.

saltydk · April 2, 2019, 5:23pm

They are using https://github.com/intel/media-driver now for the newer CPUs.

ChuckPa · April 2, 2019, 5:24pm

Thank you. I missed that. I will forward to the transcoding team but they probably already know

saltydk · April 2, 2019, 5:27pm

My friend suggested that I mention that the file naming changed. As seen on the github the new file is called iHD_drv_video.so

Agster · April 2, 2019, 7:57pm

Simple question. Would PMS on Windows 10 have the same issue? I assume not as the OS is more current.

ChuckPa · April 2, 2019, 8:20pm

I cannot speak to Windows. I’m a Linux guy.

I do know Windows uses DVXA / DXVA2 as its API which is comparable to VAAPI
Microsoft also handles all those issues internal to Windows.

Since they are better funded and have a broader customer base, I would not expect any issues whatsoever on Windows.

Agster · April 3, 2019, 4:02am

I appreciate all your time!

pl_5309 · April 3, 2019, 1:07pm

Other options, you could use ukuu to upgrade your kernel or wait till April 19 when Ubuntu 19.04 is released with 5.0 Kernel and updated drivers.

Menel · April 3, 2019, 1:14pm

This. I used ukuu back last spring to get earlier support for my 8100. nbd.

ChuckPa · April 3, 2019, 2:49pm

A point to also await is the next Plex transcoder update to see if there is support for the iHD driver or if still based on the i965
