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.
when I test Vulkan decoding with my system ffmpeg-7 according to
