Hello,
check apsclientsession.h:
// (' ', 'A', 'M', 'R')
const TUint32 KMCPFourCCIdAMRNB = 0x524d4120;
// ('G', '7', '1', '1')
const TUint32 KMCPFourCCIdG711 = 0x31313747;
// ('G', '7', '2', '9')
const TUint32 KMCPFourCCIdG729 = 0x39323747;
// ('i', 'L', 'B', 'C')
const TUint32 KMCPFourCCIdILBC = 0x43424c49;
// ( 'D', 'T', 'M', 'F' )
const TUint32 KMCPFourCCIdDTMF = 0x464d5444;
and
void CPjAudioEngine::ConstructL()
{
iSettings.iFourCC = TFourCC(KMCPFourCCIdG711); // <- change
to KMCPFourCCIdG729
iSettings.iGlobal = APP_UID;
iSettings.iPriority = TMdaPriority(100);
iSettings.iPreference = TMdaPriorityPreference(0x05210001);
iSettings.iSettings.iChannels = EMMFMono;
iSettings.iSettings.iSampleRate = EMMFSampleRate8000Hz;
iSettings.iSettings.iVolume = 0;
}
There is also an example for APS, you can figure it out about how to use all
codecs with APS.
