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”.

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.
