In case you want to play around with #libcamera and #PipeWire during #FOSDEM: here's a sandboxed #Flatpak of jwestman's "Camera" app: https://gitlab.gnome.org/rmader/camera/-/issues/1
It comes with rotation support and should work on any system with proper PW+libcamera setup - I hope we can get it on #flathub soon as test app.
The camera portal is not yet supported unfortunately.
