Hi all, I have written application for recording RTP payloaded packets. The recorded file has problem seeking. The Original file on server side is seekable. ISSUE: 1. The problem is observed when the client is started after the server (which is the usual case). NOTE : In the application the caps for the udpsrc on the client are retrieved through SAP & SDP packets, which am sending on separate IP address. The pipelines am using for server & client are as below: SERVER: gst-launch gstrtpbin name=rtpbin filesrc location=jurassic.mp4 ! qtdemux name=d d. ! rtph264pay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5002 host=224.0.0.1 rtpbin.send_rtcp_src_0 ! udpsink port=5003 host=224.0.0.1 sync=false async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_0 -v CLIENT: gst-launch gstrtpbin name=rtpbin udpsrc caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, profile-level-id=(string)4d400d, sprop-parameter-sets=(string)\"Z01ADZJSAoP2AiAAAAMDACAAAAeR4oVJ\\,aO4Cssg\\=\", ssrc=(guint)2605181711, payload=(int)96, clock-base=(guint)735690826, seqnum-base=(guint)36067" uri=udp://<a href="http://224.0.0.1:5002">224.0.0.1:5002</a> port=5002 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtph264depay ! ffdec_h264 ! x264enc ! mpegtsmux ! filesink location=test-h264-in-mpeg2ts.ts -e I would be greatful for any help for the issue.
