If a multiview stream is decoded, multiple view components are submitted as is downstream. It is the responsibility of the sink element to display the required view components. By default, always select the frame buffer that matches the view-id of the very first frame to be displayed. However, introduce a "view-id" property to allow the selection of a specific view component of interest to display.
