[FFmpeg-user] Building ffmpeg with vulkan support in docker container.

[Ferdi Scholten]

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”.

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.

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.
