Simply allocate GstRtpBuffer on the stack, and then use 
gst_rtp_buffer_map/unmap() methods.

function(buffer)
{
   GstRtpBuffer rtp_buf;

   gst_rtp_buffer_map (buffer, GST_MAP_READWRITE, &rtp_buf);

   ...

   at this point you can call method like 
gst_rtp_buffer_add_extension_onebyte_header () to modify the
   RTP buffer. When done, you must unmap the buffer otherwise the buffer 
will be left unusable.

   ...

   gst_rtp_buffer_unmap (&rtp_buf)l
}
