Hi All,

     I m trying to capture audio and encode to mp3 format and send through
rtpmpapay and decode and playback in the other system, but i m not able to
listen voice clearly. But it is good when send captured pcm format and
playback using protocol rtppcmapay and rtppcmadepay.

  Here is the command for the reference, thank u in advance and will be
greatly appreciated for the solution.

Sender : gst-launch gstrtpbin name=rtpbin alsasrc ! audioconvert !
audioresample ! lamemp3enc ! rtpmpapay ! rtpbin.send_rtp_sink_0
rtpbin.send_rtp_src_0 ! udpsink port=5002 host=172.16.10.32
rtpbin.send_rtcp_src_0 ! udpsink port=5003 host=172.16.10.32 sync=false
async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_0

Receiver : gst-launch gstrtpbin name=rtpbin udpsrc
caps="application/x-rtp,media=(string)audio,clock-rate=(int)8000,encoding-name=(string)MPA"
port=5002 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtpmpadepay ! mp3parse !
ffdec_mp3 ! audioconvert ! volume volume=3 ! audioresample quality=10 !
alsasink udpsrc port=5003 ! rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 !
udpsink port=5007 host=172.16.10.32 sync=false async=false
