[gst-devel] Seeking problem on recording RTP payloaded data

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.

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:

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= rtpbin.send_rtcp_src_0 ! udpsink port=5003
host= sync=false async=false udpsrc port=5007 !
rtpbin.recv_rtcp_sink_0 -v

gst-launch gstrtpbin name=rtpbin udpsrc caps="application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264,
ssrc=(guint)2605181711, payload=(int)96, clock-base=(guint)735690826,
seqnum-base=(guint)36067" uri=udp:// 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.
