Implement previewing functionality using 2 properties. A boolean (post-previews) that indicates if previews should be posted, and a GstCaps (preview-caps) to provide the desired preview caps. wrappercamerabinsrc implements previewing by supplying the captured image to a pipeline to adapt it to the required caps before posting.
