<div dir="ltr">RTP is a media protocol carried over UDP. In wireshark, r-click on a suspected media packet and select 'decode as -> rtp'. That will probably cause wireshark to display all packets in that stream as RTP. The header might (or might not) indicate the payload type. You can then go to the menu item Edit and select preferences. In the dialog, close to the bottom on the left is an entry for Protocols. Drop it down. If you are looking for H264 video, select it and you can enter 96 for the probabale payload type, but don't. Enter something else like 97 and select apply. Then enter 96 and select OK. There is what I consider a bug in wireshark where it won't re-scan the packet capture unless you actually change something, hence the 96->97->96 business. That will display your video packets properly. Audio should be similar. You can enter any number for the payload type, but use the correct one for your stream. You can do the same for RTCP.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Mar 20, 2015 at 2:29 AM, Raman Kumar <span dir="ltr"><<a href="mailto:raman.kumar@tcs.com" target="_blank">raman.kumar@tcs.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif"> <span>I am using two pipeline to send and receive the video but in the wireshark I can't see any RTP or RTCP message exchange only UDP packets<br><br>sender:<br><br>gst-launch-0.10 -v gstrtpbin name=rtpbin filesrc location=TestV.mp4 ! decodebin ! x264enc ! rtph264pay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5002 host=127.0.0.1 rtpbin.send_rtcp_src_0 ! udpsink port=5003 host=127.0.0.1 sync=false async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_0<br><br>Reciever:<br><br>gst-launch-0.10 -v gstrtpbin name=rtpbin latency=100 udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264" port=5002 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! autovideosink udpsrc port=5003 ! rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 ! udpsink port=5007 host=127.0.0.1 sync=false async=false<br><br><br><br>Could any one plese help me out, why I can't see the RTP message exchange in wireshark?
