How to decode G.729b codec?












0















I am developing an application that listens for RTP data using GStreamer and converts the received raw data packets using FFMPEG.
I 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 packet is received. FFMPEG has support for G729 as mentioned here but nothing is mentioned about G729a/b. GStreamer also has not mentioned anything about G729a/b though has a decoder for G729. I also didn't find any other library that can convert G729b to wav or mp3.
Can anyone please suggest any way or any library to convert G729a/b to wav.
Thanks in advance!



Command used:
ffmpeg -f g729 -i .g729 -acodec pcm_s16le -ar 8000 output.wav



Please find the two files here

  • I have edited my answer with the command and files. There are two files. One is g729 that is converted correctly and other is g729b which is not converted properly. thanks for replying @LordNeckbeard

  • Cisco call manager (CUCM) sends voip call data to recording server. Our app is on the recording server where gstreamer stores the data. For g729 the gsteramer 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 done through cisco IP phones and softphones, which means they can decode and play the codec. Wireshark (from this link wiki.wireshark.org/HowToDecodeG729) was not able to decode g729 b codec but it could decode g729.

  • I don't know anything about G.729, but consider submitting a feature request to support G.729B on the FFmpeg Bug Tracker. You will need to provide: 1) a link to a sample file like you did here 2) the actual command you tried 3) the complete log from the command 4) and make sure you're using the most recent ffmpeg you can. See the FFmpeg Download page for links to builds if you can't compile.
