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 ....

vulkaninfo | grep VK_KHR_video_decode_queue
- not found

it seems you need env variable set?

======

• Intel
  • You must set ANV_VIDEO_DECODE=1 in your environment to expose video decoding
  • Both H.264 and H.265 are supported
  • VK_EXT_descriptor_buffer support, required for Vulkan filters, has been merged but no release includes it yet

export ANV_VIDEO_DECODE=1
