G729, G723 encode, decode

[shamun.toha]

Any idea how to do or where to get

G723 or G729 decode / encode

method? for RTP, following method sending / recv packets Alredy worked out GSM codec.

form.append("Connected: " + MediaIP + ":" + MediaPort);
                udpReceive = new UDPReceive(form);
                udpReceive.setDatagramConn(rtpCon);
                udpReceive.start();


                audioCapture = new AudioCapture(form);
                audioCapture.start();

                udpSend = new UDPSend(form);
                udpSend.setDatagramConn(rtpCon);
                udpSend.setServerIP(MediaIP);
                udpSend.setServerPort(MediaPort);
                udpSend.start();
                
                Thread.currentThread().sleep(1000);
                
                audioPlayer = new AudioPlayer(form);
                audioPlayer.start();
                incall = true;

You need to use the formats supported by the platform for both recording and playback. Otherwise you need to do transcoding from/to the supported formats to/from G729/G723 after recording or before playback (which will not work well if at all)

So if the platform/device does not support G729/G723, you cannot use those formats.

If you need to use those formats, you need to do the transcoding on server-side.

Thanks for the info,

v=0
o=SIP_5F1 123456 654321 IN IP4 81.88.105.33
s=-
c=IN IP4 81.88.105.33
t=0 0
m=audio 13820 RTP/AVP 3 101
a=rtpmap:3 GSM/8000 or G723/8000 or G729/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15

- do you have any idea, for above from where i can get any example or resource to move forward regarding recv/send decode/encode G723/G729 codecs.
