i get 2 diferente signal...i get the "on-new-ssrc" signal and the "on-validated-ssrc". I supposed that because of that i am receiving the rtp, i did not tested it with tcpdump, im going to check it. thanks for the help best regards, Katcipis <div class="gmail_quote">On Sat, May 9, 2009 at 3:40 PM, Aurelien Grimaud <<a href="mailto:gstelzz@yahoo.fr">gstelzz@yahoo.fr</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Sorry, I misread your code. the pad-added signal is a signal of elements, documented in the element documentation.
