***GUIDE*** Plex Hardware Acceleration using Intel Quick Sync

[Valiran]

Hello!

 

On an i7-1260p, is that normal that Plex uses /dev/dri/card0 for hw transcode?

Shouldn't use renderD128 instead?

@lotetreemedia just another vote of thanks for your guide. I wish all guides were this helpful. I quickly managed to get hw transcoding going on my new server after pulling my hair out following other information in my searches.

This has now gotten a lot easier.  Guide below works for Intel, AMD, and Nvidia:

Hi,

 

the blacklist is not a good idea.

If i915 is in use, you should ensure that Plex is stopped before you make the changes.

 

Try these lines in the console:

rmmod i915
echo "options i915 enable_fbc=1 enable_guc=3" > /etc/modprobe.d/i915.conf
modprobe i915

 

cat /etc/modprobe.d/i915.conf

should show you the new settings for the driver which will be loaded with "mod probe i915"

 

Looks like HW-Acceleration works fine for you.

The settings in the "go" files should ensure, that the setting will be automatically done after reboot.

 

Which kind of error-message do you get?

 

 

 

 

Thank you very much, I was trying to make the plex transcoding work for days and I couldn't, now it worked.

thanks for the guide, worked without issue

I stumbled upon this thread as I'm having issues using HW transcoding when HDR tonemapping is enabled in Plex (using the hotio container). I have an Intel i3-10100 CPU with quicksync, and am running Unraid v6.11.5. HW transcoding works flawlessly in all other circumstances.

Are there any recurring issues with HW transcoding for HDR tonemapping that might cause this? Or is it more likely to be my config? I have /dev/dri/ mapped as a device in the container itself, then:

modprobe i915
chmod -R 777 /dev/dri

 

..added to /boot/config/go

 

Quick edit to mention that I removed the above lines from my /boot/config/go file as I understand these are no longer needed. Hasn't fixed my issue though unfortunately.

Thanks a lot. Could I use this trick with Tvheadend?

a question

Hi,

 

Thanks to this guide i have managed to get GPU transcoding working on my intel iGPU while also having an Nvidia 2070 installed using the HardwareDevicePath="/dev/dri/renderD129" in the preferences file.

 

The problem I am having is after rebooting unraid it seems like the number of the graphics cards sometimes switches. ie the iGPU is now renderD128 instead of renderD129.

 

Is there anything I can do to stop this happening?

 

Thanks

The only solution I have found to the above problem is to bind the 2070 to vfio at boot. I have then created a small ubuntu vm which can be enabled to put the graphics card into low power states when it isn't being used on my windows vm.

 

Might not be the most elegant solution but it appears to be working.

I will literally paypal anyone 20 to get hw transcoding on my N5105 Jasper Lake box using the LinuxServer container to work.  I've lost count of how many times I've tried between running docker on bare metal, my asustor through ADM, and now my asustor running unRAID.

Short details:

1. /dev/dri is being passed and shows in the container wide open
2. /dev/dri permissions seem correct querying user abc and validating group membership against /dev/dri
3.  Log files show attempts to use hw but no device is available
4. Running the latest unRAID 
5. What the hell else is there.....

However, I can spin up a VM, pass the gpu through, and have hw transcoding done in less then 5.  I am trying sooooooo hard to abandon this route as its not efficient at all on my current resources.

If anyone has the time to do screen sharing, could be a quick easy 20 bucks and saving me from compulsively buying 1300 in equipment, setting my asustor on my porch, and punting it as far as I can.  Then going inside to grab a bat to finish it off in grand 'Office Space' style while gangsters paradise plays on the portable speaker in the background.....

Sanity has left me...

 

BTW, brand new user, currently in trial mode to see if I really want to convert over.  Hi.

#Asustor #N5105 #Jasper
Fixed it.........finally.

For anyone else struggling, my cure, was to update the i915.conf file on the unRAID stick by removing the force_probe=4c8a option and replacing it with enable_guc=2.  I searched a little bit(not much) on what force_probe=4c8a does and couldn't find anything.  Updating the conf and executing modprobe in the OS did not reload the module and work for me.  I had to update the i915.conf on the USB to have the settings on boot otherwise unRAID just overwrites the file.

 

YMMV but use the graphic to determine which GuC and HuC level you need...
