Package: wireplumber
Version: 0.4.13-1

Somewhere deep in the log there are two error messages concerning camera:

libcamera SPA missing or broken. libcamera not supported.

What is SPA? The package pipewire-libcamera is NOT installed; it seems 
to be not recommended or even suggested by any other package. So besides 
a guess based on the name (and pipewire-libcamera may or may not be 
relevant), there's no way of knowing how to get rid of this error.  So 
who is the culprit and what to do?

Gratefully,
AlMa
