[gst-devel] Problem in G726 pipeline

[Puneeth]

Hi All,
    
   I m facing some problem with g726 pipeline when i m trying to encode PCM
audio data to G726 format and decode and playback. I m not able to hear
anything with the below pipeline, i m just able to listen some noise with
this pipeline, what changes i have to do to listen the captured PCM data.

sudo gst-launch alsasrc !
'audio/x-raw-int,channels=1,rate=8000,width=16,depth=16,signed=true,endianness=1234'
! ffenc_g726 bitrate=16000 ! ffdec_g726 ! alsasink --gst-debug=2

Following are the warnings i m getting when i run this pipeline....I would
really appreciate if anyone could find me the solution..Thank you in
advance.

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
