Hi All, I am using following pipeline to play the video: gst-launch -v gstrtpbin name=rtpbin audiotestsrc ! amrnbenc ! rtpamrpay ! rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 ! udpsink port=5002 rtpbin.send_rtcp_src_1 ! udpsink port=5003 sync=false async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1 on the receiver side i am receiving the RTP and RTCP packets perfectly. My problem is when i try writinh the test application for the same, if only RTP data is sent, it works fine but if  RTCP data is also sent along with the RTP is there no data is transmitted, there is no data received on the receiver side. In both the case the pots, IP and the receiver pipeline are same. Please help me in finding the problem.. Thanks a ton in advance Manish <div class="gmail_quote">On Wed, May 21, 2008 at 2:23 PM, Manish Rana <<a href="mailto:manish.rana@gmail.com">manish.rana@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">to get the data set a property on sink "sync=false" this will help you getting the data <div><div></div><div class="Wj3C7c"> <div class="gmail_quote">On Wed, May 21, 2008 at 12:40 PM, ved kpl <<a href="mailto:ved.kpl@gmail.com" target="_blank">ved.kpl@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, Which version r u using?. The error states that the caps are not getting negotiated in ur receiving pipeline, one of the elements there doesnot support the incoming format. I tried the same pipelines,. It didnt throw any errors, although nothing got displayed at the receving end. Try using xvimagesink or some other sinks directly instead of autosink. Also try  other formats like audio eg. mpeg audio mp3..(rtpmpadepay/pay) Cheers Ved On Wed, May 21, 2008 at 4:34 AM, Jon Dufresne <<a href="mailto:jon.dufresne@gmail.com" target="_blank">jon.dufresne@gmail.com</a>> wrote: > I am trying to experiment with gstreamer.
