Hello,
Attempting to build ffmpeg that has vulkan support enabled in a
docker container. The container environment is ubuntu 24.04 with
installed packages libvulkan-dev, (libvulkan1), vulkan-icd,
vulkan-tools. As far as I understand vulkan is supposed to be
autodetected by ffmpeg configure (but does not enable by itself) and
when trying to pass `--enable-vulkan`, configure will exit error
“ERROR: vulkan requested but not found”.
I have confirmed vulkan is able to detect hardware gpu when the
container is running, but hardware access a bit more limited while
building (from Dockerfile). Don’t know whether detected gpu hardware
in vulkan matters at build time, but as the vulkan-icd package is
installed some software/cpu support should at least be enabled.
VK_HEADER_VERSION 275
Ffmpeg 7.1
Any pointers where to look to get this working? Thanks.
_______________________________________________
I once had the same problem, looking at the logging generated it
turned out that the vulkan version used by Ubuntu was too old.
since then I build vulkan myself from git. Current vulkan version is
300 by the way.

A quick check confirms your vulkan version is too old:
check_pkg_config_cpp vulkan vulkan >= 1.3.277 vulkan/vulkan.h defined
VK_VERSION_1_3
