Nice work Olivier! This would be really useful API that would enable me to drop
CheeseCameraDeviceMonitor in Cheese. The API seems fine to me on first glance,
and is more generic than the custom monitor that Cheese has.

I wonder if the name property on GstDevice is something that would be unique
and be preserved across replugging? Currently, Cheese stores the path to the
active V4L2 device in GSettings, so that the choice can be preserved across
application restarts, and although I could do the same thing with a GStreamer
device monitor, I wonder if a GstDevice should directly provide some kind of
UUID or persistent identifier. Anyway, this could be added at some later time,
and the API already seems really useful. I will see if I can find some time to
work on some patches for Cheese as an example consumer.
