Can I use 2 GPUs for transcoding?

[crash1015 5]

I know I’ve asked about this before and the answer was no at the time, but that was when i had two NVIDIA GPUs. I’ve replaced my NVIDIA Quadro P2000 with an Intel Arc A380, and I’m curious whether Emby might now be able to utilize both GPUs in some capacity, because they come from different drivers maybe? Ideally, I’m wondering if it’s possible to split the load between the two cards somehow. Just wanted your thoughts.

 

Thanks!!!

And it's still no.

You can select one or another in transcoding settings, but there’s no automatic scaling. 
I found the Intel Arc transcoding feature is broken when needing tone mapping too.

You can assign specific encode and decode functionality to a specific card.
You could for example assign AV1 encoding and decoding to an ARC GPU while having everything else assigned to another GPU.
But in this case unless a transcode was AV1 originally and being converted to AV1 it could be using two different GPU for the process.
You would need to plan/test how to best utilize the cards.

Intel's drivers haven't been the most successful on that frost.
If running Emby from docker try using the environment:

NEOReadDebugKeys = 1
OverrideGpuAddressSpace = 48

Like in the image i attached to this post.

That fixes the problem in Unraid at least.

That's what i'm thinking too. I'll give this a shot.

lolol i knew this was coming.

OverrideGpuAddressSpace has been added on the beta channel. Thanks.

You helped me too. I wonder why my 13900HK igpu only being use slightly. Now they are fully used
