Intel Hades Canyon NUC, hardware transcoding

[Mini_Server_1]

@Ionut_David

OK so I did the thing you suggested and added Plexmediaserver.exe to the graphics performance profile, and no luck.

I then added both Plexmediaserver.exe AND PlexTranscoder.exe and that DID seem to make a difference. As seen in the attachment it now looks like the Intel iGPU is used for Video decoding.

I think this did the trick!!!

I posted a thread a while back regarding the dual GPU and selection for transcoding, my testing showed that Plex doesnt chose which GPU it can use for transcoding, and I think defaults to the integrated graphics, which is not good, unless the dedicated graphics card cannot transcode (intel smart graphics)

My solution was to disable the integrated graphics to ensure Im using the best graphics card to transcode.

does this allow plex to use both cards? decode on one and encode on the other if it has the ability to do so? does it use the intel graphics and dedicated?

Hi,

Im having the same issue as the original poster on Windows 10 also Transcoding is HW but using the AMD GPU not the Intel 630 which has quicksync

from log:

May 20, 2019 18:03:37.358 [10588] DEBUG - TPU: hardware transcoding: enabled, but no hardware decode accelerator found
May 20, 2019 18:03:37.359 [10588] DEBUG - TPU: hardware transcoding: final decoder: , final encoder:
May 20, 2019 18:03:37.360 [10588] DEBUG - Job running: EAE_ROOT=’\?\C:\Users\pavlo\AppData\Local\Plex Media

Have a monitor connected also to confirm as well as having tried a dummy HDMI plug. Also tried the suggestions of putting Plexmediaserver.exe and transcoder to the high performance graphics profile but regardless of what i do the Intel 630 graphics sits there on 0% utilisation.

Any help would be appreciated.

Cheers

Hi there,

I didn’t have time to update this topic in the past, but my initial solution that has worked when I opened this topic is no longer working.

Putting the Plexmediaserver.exe and Plextranscoder.exe as “power saving” in the graphics profile no longer works. This has happened immediately after the 6577 driver update that was released a few months ago.

Falling back to a driver prior to that (eg. 6519) will make this solution work again.

At this point I’m a bit disappointed that there’s no way Plex could introduce an advanced manual GPU selection in their settings, so I just gave up and ended up using the AMD GPU for transcoding.

Hi

Thanks for the quick reply I’ll try installing the older drivers and see if that works. Does it make a big difference using the Intel iGPU over the AMD one?

Cheers

Well, it’s been said that Intel’s QuickSync offers better quality results than AMD’s VCE. Though I don’t think the difference is that clearly visible.

Either way the idea of using the Intel iGPU made sense because it’s there sitting, doing nothing, and it’s better to use it for this kind of stuff and leave the dGPU to do some other tasks.

Just wanted to update that reverting my intel iGPU drivers to version 6519 and using the “power saving” profile for the two processes has forced the transcoding to use the intel GPU.

Thanks again Ionut_David, hopefully Intel fix there newer drivers so this is no longer an issue but this is a good fix for now.
