           Summary: v4l2src should clear formats list when it closes the
                    device
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

   GNOME milestone: Unspecified


Currently v4l2src calls gst_v4l2src_clear_format_list in the dispose method so
if you set the element to NULL, change the device and set it to READY again it
doesn't refresh its formats list and sets caps from the previous device format
list.
At a quick glance I'd say it should be better to call clear_format_list and
unref probed_caps in the stop method so that it gets called on READY->NULL.
