Details

Currently the libvulkan.so dependency does not define version (=1-64), which makes it ambiguous between vulkan-icd-loader and lib32-vulkan-icd-loader. The makepkg command does not able to fill the version, because ffmpeg uses dlopen() to load this library dynamically:
https://github.com/FFmpeg/FFmpeg/blob/cc76e8340d28438c1ac56ee7dfd774d25e944264/libavutil/hwcontext_vulkan.c#L302-L334

Please replace 'libvulkan.so' with 'vulkan-icd-loader' in depends=() of ffmpeg.
This task depends upon

Yeah, depending on *.so libs for dlopened libraries does seem like a bit of a trap for young players...and therefore a possible flaw in our current *.so dep guidelines.

I decided to not fill Flyspray with a hundred of similar tasks, so I created a TODO list instead:
