Hi!
I've been playing around with pjsip for several days and i'm trying to
make my own 'hello world' softphone to learn how to use the library :)
Now i'm a little stuck getting incoming call ringtone to work. I've
done the following:
I've defined the incoming call callback, and inside that function, I
call another function: ring();
ring() basically does nearly the same as playfile.c sample, but I
paste the code just in case:
static void ring(void)
{
pj_caching_pool cp;
pjmedia_endpt *med_endpt;
pj_pool_t *pool;
pjmedia_port *file_port;
pjmedia_snd_port *snd_port;
char tmp[10];
pj_status_t status;
/* Para poder asignar memoria din?micamente tenemos que crear
una 'pool factory' */
pj_caching_pool_init(&cp, &pj_pool_factory_default_policy, 0);
/* Inicializamos el endpoint */
status = pjmedia_endpt_create(&cp.factory, NULL, 1, &med_endpt);
if (status != PJ_SUCCESS)
return;
/* Creamos un pool de memoria para el reproductor */
pool = pj_pool_create( &cp.factory, /* pool factory */
"wavplayer", /* pool name. */
4000, /* init size */
4000, /* increment size */
NULL /* callback on error */
);
/* Creamos el media port del fichero wav */
status = pjmedia_wav_player_port_create(pool, /*
memory pool */
RINGTONE, /*
file to play */
20, /*
ptime. */
0, /*
flags */
0, /*
default buffer */
&file_port /*
returned port */
);
if (status != PJ_SUCCESS) {
printf("No se puede usar ese archivo WAV: %s\n", status);
return;
}
/* Creamos el puerto para el reproductor de sonido */
status = pjmedia_snd_port_create_player(
pool, /* pool */
-1, /* use default dev. */
file_port->info.clock_rate, /* clock rate. */
file_port->info.channel_count, /* # of channels. */
file_port->info.samples_per_frame, /* samples per frame. */
file_port->info.bits_per_sample, /* bits per sample. */
0, /* options */
&snd_port /* returned port */
);
if (status != PJ_SUCCESS) {
printf("No se pudo abrir el dispositivo de audio:
%s\n", status);
}
/* Conectamos el puerto del fichero a la tarjeta de sonido. La
reproducci?n comenzar? inmediatamente. */
status = pjmedia_snd_port_connect( snd_port, file_port);
if (status != PJ_SUCCESS) {
printf("Error conectando el puerto de audio: %s\n", status);
return;
}
Now, when I get an incoming call, the file starts plying and it loops
infinitely, which is OK, BUT, I want the file to stop plying when I
type 'answer' at the main loop prompt.
The issue is: how can I access the sound port again? Shoul I use
global variables? or open another thread and when I type 'answer'
return there and do my stuff?
I hope my explanation is fine :) Sorry for the long mail.
Thanks in advance for any help.
