What do you get from the image-capture-supported-caps and for the video 
one? Do they have the natively supported formats first in the caps just 
like the viewfinder one below? Is it enough for your use case to have 
them in the order of preference (native first, converted last) or would 
you want to have only native?

It should be possible to add a property to wrappercamerabinsrc to get 
the native supported caps. Patches welcome.
