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.
