Intel Arc A380 DVXA2 Hardware Acceleration not working in Windows?

I received a A380 today and promptly installed it in my Windows Server 2019 Plex server with an older Xeon v5 with iGPU, no resizable bar available.
Latest Intel drivers installed but not the Arc controller. Disabled the iGPU and ran some tests. Plex is not utilizing the A380 for transcoding. 
I have been testing this on the Plex forums and it seems that dvxa2 is not implemented. When and/or will this be implemented?

This is all detailed in this PLEX thread

It seems Plex uses DXVA2 (instead of D3D11) for decoding on windows, this would also affect any other applications that transcode video files using DXVA2 so not related directly to plex.

Hi Steve,

 

Here is the information you requested


-What driver version are you currently using?
Intel® Graphics Beta Driver 31.0.101.3430

 

-Have you tested if this behavior has been replicated on other non-server Windows versions?
The only hardware I have to test on is running Windows Server 2019

 

-Please share with us the model of your CPU and motherboard. As well as some details about your current setup. For example: If this is a pre-build server or a custom build, the function of this GPU while using Plex TV and what other devices may you have connected?
Dell Poweredge T30
Processor Name: Intel Xeon E3-1225 v5
RAM: 32GB Micron 18ASF2G72AZ-2G6D1
Motherboard Model: DELL 07T4MC
Motherboard Chipset: Intel C236 (Skylake PCH-H)
Symbios Logic/LSI SAS2008 PCI-Express Fusion-MPT SAS-2 Controller
Intel I350 Gigabit 1000BaseT Network Ethernet Adapter (Copper)

The function of the Intel Arc A380 is intended strictly for Quick Sync hardware encoding/decoding video. No gaming.

The only hardware I have to test on is running Windows Server 2019

 

-Please share with us the model of your CPU and motherboard. As well as some details about your current setup. For example: If this is a pre-build server or a custom build, the function of this GPU while using Plex TV and what other devices may you have connected?
Dell Poweredge T30
Processor Name: Intel Xeon E3-1225 v5
RAM: 32GB Micron 18ASF2G72AZ-2G6D1
Motherboard Model: DELL 07T4MC
Motherboard Chipset: Intel C236 (Skylake PCH-H)
Symbios Logic/LSI SAS2008 PCI-Express Fusion-MPT SAS-2 Controller
Intel I350 Gigabit 1000BaseT Network Ethernet Adapter (Copper)

The function of the Intel Arc A380 is intended strictly for Quick Sync hardware encoding/decoding video. No gaming.

Hello Compsmith,


Thank you for your response.


We are going to check this information again and continue with our internal research. As soon as I have any updates I will post them here.



Best regards,

I'm also interested in using an Arc GPU in this same use-case.  I have a Plex server running Windows Server 2019 because Windows 10 no longer supports my RAID card and RFS is exclusive to Windows server.  I see that the ARC drivers don't mention compatibility with Windows Server.  Am I going to have to stick with nVidia or Radeon for my home media?

Hello compsmith,


 

As per our investigation, we checked that the latest driver 31.0.101.4032 includes improvements on DirectX 9. I understand you have already tried different drivers versions, but to continue the investigation please follow the steps below:


  • Download the driver on Download Center, and install t following the steps on How to Install an Intel® Graphics Driver in Windows® 10 & Windows 11 method 2.
  • If the issue persists after the previous step, provide app logs, as you did before for further research.
