           Summary: [API] baseparse: need vfunc to intercept queries
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---


GstBaseParse needs a vfunc for queries, so we can intercept ALLOCATION queries
in video parsers and add our own meta, for example, and/or find out what
downstream supports.

There's a patch here, though we might want to bikeshed about the naming a bit
more :)
