Arc a750 not available for encoding

[Irondudetoo 1]

Emby Premiere 4.8.8.0, run as application

installed an Intel a750 dGPU, latest drivers, monitor attached. Will show on the list of decoders but no encoders listed. Can confirm encoding with cpu. if I plug monitor into intel iGPU, both show on list of decoders but only the Intel iGPU on the list of encoders. it will encode with iGPU selected.

Also tried with 4.9.0.30 beta.

Handbrake will use the a750 as QSV accelerated. 

Any ideas to make Emby see the a750.

Thanks

Hi there, please attach the emby server log and hardware detection log files. Thanks !

@Irondudetoo

Is there any virtualization in place?

Did you install the latest Intel drivers from the Intel website?

[Irondudetoo 1]

no virtualization. bare hardware.

i7-7700, win 10 x64.

latest drivers - 32.0.101.5989 - 09/04/2024

Thanks

[softworkz 5066]

The latest driver which explicitly states support for your OS (Win 10 21H2) is this one: https://www.intel.com/content/www/us/en/download/785597/828379/intel-arc-iris-xe-graphics-windows.html

Not sure whether it makes a difference, though.

[Irondudetoo 1]

I gave it rip with the drivers you listed, but same result.

Other ideas?

Thanks

Could you please run dxdiag, then "Save All Information" and post the output?

Dxdiag:

DxDiag.txt

(Haven't looked at the dxdiag log yet...)

What looks suspicious is that the system indicates that there would be 5 graphic adapters on your system and 3 of them create errors, so that we can't even retrieve basic information (like adapter name, etc):

 

The actual errors from the information retrieval are a bit hidden (end of a long line):

 

I can imagine very well that the Intel implementation of QSV does the same enumeration and because it fails on that, it might not even work for the first adapter (Arc).

Handbrake may possibly use QSV via D3D9 rather than 11 like we do.

 

[softworkz 5066]

DxDiag show just one display adapter - but that's probably normal as it's supposed to show direcx display devices only.

The question is: where are those 5 devices coming from? Any idea?

Do you see anything in Device Manager?
Is there any software installed which might create any kind of (virtual) display adapters?

[softworkz 5066]

As a last resort, you could also make Emby Server use D3D9.

To enable this, you need to install the "Diagnostics Plugin" from the catalog, this will give you a new entry "Diagnostic Options":

 

Don't forget to press SAVE, then restart Emby Server and wait a moment for the hw detection to finish.

@Irondudetoohas this resolved your issue?

[Irondudetoo 1]

No, I gave up for now, just using the a750 for decoding, and iGPU for encoding.

I tried a fresh install of Win10 just make sure it wasn't anything left in the setup from the old, old system.

Will work with it later when I have some time, probably in Nov.

Thanks.

@Irondudetoohas this advice helped?

Been a while since i worked on this. i replaced the mb/cpu with a newer b760/i5-12600K back in Dec 2024. A750 still not recognized. i just used the iGPU since it was fast. Fast Forward to now. i installed the A750 again, downloaded newest drivers and presto, it recognizes the a750 for encoding/decoding along with the iGPU 770. i don't know if it was arc drivers as i was using the latest at the time(went thru several revisions) or some win 10 update. Yes this card work great for Emby and fast at encoding.

Yes, Intel have been messing around with drivers for quite some time.
