Hi to everyone.
I have a stereo codec on my arm board and I need to run 2 different
instance on linphonec, one for left and one for right channel.
The problem is that I can't tell linphone to use a virtual device.
In my asound.conf I wrote something like:
pcm.record_left {
type dsnoop
ipc_key 234884
slave {
pcm "hw:0,0"
channels 2
}
bindings.0 0
}
pcm.record_right {
type dsnoop
ipc_key 2241234
slave {
pcm "hw:0,0"
channels 2
}
bindings.0 1
}
If I record a wav file with:
# arecord -D record_left left.wav
or
#arecord -D record_right right.wav
it works properly (I record only the left or right audio in a mono file).
But if I configure the .linphonerc:
[sound]
capture_dev_id=ALSA: record_left
it says:
ortp-warning-no card with id ALSA: record_left
In fact, I modifyed mssndcards.c to display the audio cards it can use:
MSSndCard * ms_snd_card_manager_get_card(MSSndCardManager *m, const
char *id){
MSList *elem;
for (elem=m->cards;elem!=NULL;elem=elem->next){
MSSndCard *card=(MSSndCard*)elem->data;
ms_warning("--- card id %s",
ms_snd_card_get_string_id(card)); // <<<<<<<<<<<<
if (id==NULL) return card;
if (strcmp(ms_snd_card_get_string_id(card),id)==0)
return card;
}
if (id!=NULL) ms_warning("no card with id %s",id);
return NULL;
}
and at startup it prints:
..............
ortp-warning---- card id ALSA: default device
ortp-warning---- card id ALSA: imx-3stack
ortp-warning---- card id OSS: /dev/dsp
............
no mention about record_left or record_right virtual device
What can I do? Please help!
