           Summary: basesrc: possible pool and allocator leak in
                    prepare_allocation()
    Classification: Platform
           Product: GStreamer
           Version: git

            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)

     GNOME version: ---


I notice that I have a bufferpool leak when start method of bufferpool returns
FALSE with a source element.

It caused by the fact that gst_base_src_prepare_allocation or
gst_base_src_set_allocation don't unref pool and allocator when a bufferpool
can't be active.

I will attach two differents solutions.
