Comment (by sameerthapaevontech):
I am developing an application that listens for RTP data using GStreamer
and converts the received raw data packets using FFMPEG. It works well for
codes: PCMA, PCMU, G722 and G729 and converts the received audio files
into wav and mp3. But the conversion fails when G729b stream is received.
FFMPEG has support for G729 but nothing is mentioned about G729a/b. I
didn't find any other library/software that can decode G729b to wav or
mp3.
Cisco call manager (CUCM) sends voip call data to recording server. Our
app is on the recording server where gstreamer stores the rtp data. For
g729 the gstreamer pipeline is: udpsrc port=5008
caps="application/x-rtp,channels=(int)1,media=(string)audio,payload=(int)18
,clock-rate=(int)8000,encoding-name=(string)G729" ! rtpg729depay !
filesink.
Call is made through cisco IP phones and softphones, which means they can
decode and play the codec.
