Well typically when you receive from a socket the host binding or sockaddr is separate from the actual received buffer. It does look like udpsrc is using GstNetBuffer instead of GstBuffer and the source addr/port is is added to the buffer. The down stream element should be able to cast the received buffer as a GstNetBuffer and extract the source addr/port. <div class="gmail_quote">On Mon, Apr 19, 2010 at 3:42 PM, Donny Viszneki <<a href="mailto:donny.viszneki@gmail.com">donny.viszneki@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> I would think the source host would be a property of a UDP packet and not a listening UDP socket :) <div><div></div><div class="h5"> On Mon, Apr 19, 2010 at 6:34 PM, Attila RS <<a href="mailto:avgrind911@gmail.com">avgrind911@gmail.com</a>> wrote: > Is there anyway to get the source host/port from udpsink?
