Actually, not quite true, I forgot the offset adjustment for the codec data for
version 4 streams (71 => 73). Fixed in the commit.

        Based on patch by: Roland Kay  <roland.kay at ox compsoc net>

        * gst/realmedia/rmdemux.c: (gst_rmdemux_parse_mdpr):
          For version 4 streams, read the extra codec data size from the
          header instead of assuming it is always 16 (also read it from the
          right position) (#384989). For version 4 and 5 streams, check that
          the specified extra codec data size doesn't make us read beyond the
          chunk boundary (#384989).
