[FFmpeg-user] Query on ffmpeg for RTP Transrating

I want to receive RTP Packets from RTP Server and transrate and feed the
output to client.So to do the same, i placed a content in local folder and
used ffmpeg to copy audio and video from it and generate two streams of rtp
which can be played at Client

ffmpeg -fflags +genpts -re -i test.mpg -vcodec copy -an -f rtp rtp:// -vn -acodec copy -f rtp rtp://

The sdp file is copied to the client and the client wishes to open the SDP
file and packets are received but they are not getting played at Client

Wire shark shows that client receives RTP and RTCP packets but they are not
playing at VLC player

Please let me know what is the issue?

Any pointer on the same topic would be appreciated where i would be able to
feed rtp streams to ffmpeg and transrate and generate two rtp streams which
can be played at client

Btw  i am using 0.9 version  of ffmpeg
