[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.

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://224.0.0.1:5002 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.

Thanks,
Jyoti
