[Linphone-users] Force to use specific audio format

[Deroo Stijn]

Hi,

I want linphone to force to only use one audio format, therefore I create this 
audio payloadtype and set this as codec list to the linphone_core object (see 
below).

The list is ok, meaning it just contains this single audio format, but when the 
invite is called, other audio formats are in the sdp.

Why doesn't linphone take this list which is set by doing 
linphone_core_set_audio_codecs??

int main()
{
LinphoneCoreVTable vtable={0};
LinphoneCore *lc = linphone_core_new(&vtable, NULL, NULL, NULL);
const MSList *codecs;
const MSList *list;
const char* mimetype = string("TLV16").c_str();
PayloadType *payloadtype = new PayloadType();
LinphoneCall *call = NULL;

payloadtype->type = 0;
payloadtype->clock_rate = 32000;
payloadtype->bits_per_sample = 0x10;
payloadtype->pattern_length = 2;
payloadtype->normal_bitrate = 512000;
payloadtype->mime_type = (char*)mimetype;
payloadtype->channels = 1;

codecs = ms_list_append(NULL, (void*)payloadtype);

linphone_core_set_audio_codecs(lc, (_MSList*)codecs);

linphone_core_enable_logs(NULL);

linphone_core_invite(lc, "address@hidden");
}

Kind regards,
Stijn.
