rport function is not calling
Hi
I have a PC with 2 sound cards. i used this snippet of code to stablish a
connection as described in https://trac.pjsip.org/repos/wiki/FAQ#multi-snd
void MyCall::onCallMediaState(OnCallMediaStateParam &prm)
{
pjmedia_snd_port *sndport = NULL;
pjmedia_port *splitcomb = NULL;
pjmedia_port *revch = NULL;
int slot;
static int sound_device = 1;
pjsua_call_id call_id= this->getInfo().id;
pjsua_call_info ci;
pjsua_call_get_info(call_id, &ci);
pj_status_t status;
status =
pjmedia_snd_port_create(pjpool,sound_device,sound_device,8000,1,160,16,0,&sndport);
status = pjmedia_splitcomb_create(pjpool,8000,1,160,16,0,&splitcomb);
status = pjmedia_splitcomb_create_rev_channel(pjpool, splitcomb,0,0,
&revch);
status = pjsua_conf_add_port(pjpool, revch, &slot);
status = pjmedia_snd_port_connect(sndport, splitcomb);
pjsua_conf_connect(ci.conf_slot,slot);
pjsua_conf_connect(slot, ci.conf_slot);
sound_device++;
}
The result is ok, and i have sound in both sound card 1 and 2 with
diferrent call sources.
I have a board with a SOC that 2 sound ports are enabled, so there are 2
sound cards on it exactly like PC. but when i run code mentioned above,
there aren't any sound from embedded board.
I debugged the library and found that in PC when functions like get_frame
and put_frame called the functions rport_put_frame and rport_get_frame are
also called respectively.
but in embedded board only get_frame and put_frame functions are called.
what is the reason for this behaviour and how can i solve this issue?
thanks
I debugged the library more and found that in PC system i have a back trace
like below:

This means that in PC the get_frame function that exists in conference.c is
called but in embedded board splitcomb version is called.
Anyone has an idea about this behaviour?
