If a property is needed it is in wrappercamerabinsrc, camerabin doesn't know
what kind of element you are using as the camera-source in it.

wrappercamerabinsrc will add a videoconvert and a videoscale, the videoconvert
is for convenience and maybe it could be disabled by adding a 'flags' property.
The videoscale is needed for the digital zooming feature.

Can you share the caps you are getting when you ask the possibilities? Are you
doing this in READY state at least? in NULL some elements won't have their
devices open and you might get ANY result. The caps you get should have the
prefered formats (native) ones first before the ones that will require
transformations.

Another option is to query the source pad of the video source directly.
