           Summary: stream live audio (from Mic) over rtp from a host to a
                    client through adpcm(g726) compression

I am trying to stream adpcm (G726),32kbps audio from a host to a client through
RTP:
I have tried following commands from the client(receiver) and the host(sender).
Both boards are connected through IP.
I am getting "internal data flow error" at the receiver once i run the cmds on
the sender:

RECEIVER:
gst-launch -v udpsrc port=3004 caps="application/x-rtp” ! rtpg726depay !
ffdec_g726 ! alsasink

SENDER: 
gst-launch -v autoaudiosrc ! audioconvert ! audioresample ! ffenc_g726
bitrate=32000 ! rtpg726pay ! udpsink host=192.168.1.104 port=3004


If I try the same with pcm, alaw encoder and decoder, then streaming works
fine. I can hear the live audio(when I speak on sender's Microphone) into
receiver's speakerphone:
commands I am running in this case:
RECEIVER:
gst-launch udpsrc port=3004 caps="application/x-rtp" ! rtppcmadepay ! alawdec 
! alsasink

SENDER: 
gst-launch autoaudiosrc ! audioconvert ! audioresample  ! alawenc ! rtppcmapay
! udpsink host=192.168.1.104 port=3004


This seems to be an issue in the pipeline?


here is the full error I am getting at the receiver
