The v4l2 media controller kernel interface is quite dynamic. It allows to query
the hardware topology. If we map that to gstreamer we can register
proxy-elements for each camera component (sensor-src, scaler, filters). The
problem here is that one needs to open the media controller device and
enumerate it - it is not static.
It is kind of similar to the plugin dependency mechanism, but we can't just
cehck this from the file-system. It would be ugly if we need udev scripts to
update some topology dump in the file-system when the hardware changes, so the
the plugin dependency mechanism could act on it. Any better idea?
