           Summary: basetransform not handles ro/rw buffer flagging for
                    transform_ip in all cases
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: ensonic at sonicpulse.de
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


two issues:

(1) basetranssform class does not make sure that buffers given to transsform_ip
in passthrough-mode as read-only. This us required so that elements can
immediately return, if they don't do analysis of the data or the like.

(2) if src and sink-caps of an element are the same
gst_base_transform_prepare_output_buffer() just returns the in_buf as out_buf,
but refs the in_buf. Then in_buf and out_buf are not writeable anymore.
