media-driver VS compute-runtime

You might need to install the non-free intel media driver: https://github.com/intel/media-driver

Intel had VP9 decode since Kaby Lake (7th gen); original Skylake (6th gen) could not handle it (see here).

I've heard intel-media-driver was the way to go for supported hardware, but I also heard that it could decode slower than libva-intel-driver (like #925), and that Intel doesn't officially support some kind of decode feature in intel-media-driver, but it's implemented in libva-intel-driver.

I reproduced the issue on my end and opened a ticket to let intel devs know. https://github.com/intel/media-driver/issues/1628

I can see 22.6.6 was released in December ( Releases · intel/media-driver (github.com) ), but I'm having troubles getting it installed.

You should be able to choose FFmpeg VAAPI encoder, though it is suggested that kernel 6.2 is needed for this to actually work. I can confirm that it's broken with my A770, while I can choose the device, encoder is failing. No such problem with my Rapter Lake iGPU.

On GitHub there are similar problems reported: https://github.com/intel/media-driver/issues/1282

Well... Fuck! https://github.com/intel/compute-runtime/issues/643

For what it's worth, I was able to get IOMMU enabled and iGPU passthrough working for Plex on an Ubuntu 22.04 LXC container with a fresh install of Proxmox 8.0.3 (kenrel 6.2.16-3-pve) on an Intel i5-13400, ASRock B760M Pro RS/D4, also using Intel drivers released early today. I largely followed this guide.

For this little project unless someone chimes in with experience or can point to regarding the RX 6600 XT / 6650 XT / perhaps 7600 I might go with https://github.com/intel/compute-runtime . (They don't have perfect documentation re supported gpus either, the readme table doesn't list DG2, you need to go to releases to see that) . Phoronix reported it as pretty stable when they tested it with kernel 6.2 in March.

Update: I was able to fix my issue. I'm using Ubuntu 22.04.2 LTS and have the newest available kernel, 6.3.1. Installing the drivers via apt does not work, instead I needed to use https://github.com/intel/compute-runtime/releases/

For OpenCL HDR/DV tone-mapping, install the extra compute-runtime if running on host.
