I could never get decoding to work with vulkan (h264), problems with
the "device." 

I also get

[h264 @ 0x560566feda40] Device does not support the VK_KHR_video_decode_queue extension!
[h264 @ 0x560566feda40] Failed setup for format vulkan: hwaccel initialisation returned error.

I think you need vulkaninfo to see if you have this extension exposed ?

driver for Intel called "anv" in mesa so may be check for this ext. name in mesa's git?

for AMD it will be "radv"

not sure how they packaged on your  distros ....

I installed a few more vulkan related packages included vulkan-tools with vulkaninfo. So now I have

- looks ok

For me it seems like Vulkan and Intel drivers should work,
though the missing VK_KHR_video_decode_queue prohibit the ffmpeg benchmark test?

(On my legacy workstation w/MSI Skylake & Nvidia GeForce GTX 960 GPU, I was not able to get corresponding info,
So I expect either it is too old and not supported, or there is some missing driver or setup)
