I use IPP G729 with pjsip and it works flawlessly. To check if the codec is
loaded you can call pjsua_enum_codecs() to check or display what codecs are
loaded.
pjsua_codec_info codec[32];
ZeroMemory(codec, sizeof(codec));
unsigned uCount = 32;
if (pjsua_enum_codecs(codec, &uCount) == PJ_SUCCESS)
{
printf("List of codecs:\n");
for (unsigned i=0; i<uCount; ++i) {
printf(" %d\t%.*s\n", codec[i].priority,
(int)codec[i].codec_id.slen,codec[i].codec_id.ptr);
}
}
To specify which codec a call uses, you should indicate the codec priority
for each codec using the api pjsua_codec_set_priority. Below is an example
that makes G729 the highest priority (you would need to specify all codecs
you are using). If you set the priority to zero, the codec is disabled.
pjsua_codec_set_priority( &(pj_str("G729/8000/1")),208);
pjsua_codec_set_priority( &(pj_str("iLBC/8000/1")),207);
pjsua_codec_set_priority( &(pj_str("PCMU/8000/1")),206);
pjsua_codec_set_priority( &(pj_str("PCMA/8000/1")),205);
pjsua_codec_set_priority( &(pj_str("GSM/8000/1")), 204);
pjsua_codec_set_priority( &(pj_str("SPEEX/8000/1")),203);
An example of specifying G729, only.
pjsua_codec_set_priority( &(pj_str("G729/8000/1")),208);
pjsua_codec_set_priority( &(pj_str("iLBC/8000/1")),0);
pjsua_codec_set_priority( &(pj_str("PCMU/8000/1")),0);
pjsua_codec_set_priority( &(pj_str("PCMA/8000/1")),0);
pjsua_codec_set_priority( &(pj_str("GSM/8000/1")), 0);
pjsua_codec_set_priority( &(pj_str("SPEEX/8000/1")),0);

Subject: Re: how to integrate g729 in pjsip
Hi Nanang,
I've build PJSIP successfully with IPP codecs enabled,
according to the instructions from
http://trac.pjsip.org/repos/wiki/Intel_IPP_Codecs, I am confused how do I
know that g729 codec is activated or not.
What I am doing is making a dll from pjsip and add it to my softphone, but I
didn't see any g729 codec in my softphone whereas other codec like GSM, G722
are there. Please tell me the simplest way to check that the codec g729 is
enable or not.
Thanks and Regards,
Elangbam Johnson
