hello everyone,
I'm working on aplication which should be know enable/disable right,left or
both audio channels. I'm trying to do this with API
pjmedia_splitcomb_create()
pjmedia_splitcomb_set_channel()
I don't want reimplement own pjsua_set_snd_dev (and othhers) like in
STEREO_DEMO (pjsua_app.c) because using in demo is follow:
1) Disable existing sound device
2) Create stereo-mono splitter/combiner
3) Connect channel to conference port slot0
4) Create sound device
5) Connect the splitter to the sound device
+-----------------+ stereo +------------------------+ +-----------
| AUDIO DEV | <------> | SPLITCOMB left|<----->|#0 BRIDGE
+-----------------+ | right|<----->|#1
+-----------------------+ +--------
When i use this way i have to rewrite own pjsua_set_snd_dev method
because this method ensure: select right clock rate and make resample port.
I want make something like this:
BRIDGE
+-----------------+ +---------------------------
| AUDIO DEV | <--------> | #0 AUDIO
+-----------------+ |
|
+------------------> | #1 SPLITER
| |
V |
+-------------------+ |
| SPLITCOMB | <-----> | #2 LEFT CHANNEL
| | <-----> | #3 RIGHT CHANNEL
+-------------------+ |
+------------------------
Then i want connect conference port 0 to 1 and reverse
pjsua_conf_connect(0,1)
pjsua_conf_connect(1,0)
and then i will be connect each call to:
port 0 if i want both channels
port 2 if i want left channel
port 3 if i want right channel
Here is my order:
1) Create stereo-mono splitter/combiner with:
pjmedia_splitcomb_create(
d->pool,
masterPortInfo.clock_rate,
2,
2 * masterPortInfo.samples_per_frame,
masterPortInfo.bits_per_sample,
0,
&d->sc ); //my spliter-combiner
2) Add to conference bridge splitter port (port #1)
pjsua_conf_add_port( d->pool, d->sc, &splitterConfID );
and now i want connect spliter channel (right,left) to conference bridge..
but how?...in STEREO_DEMO conferenvce port in bridge exist (port 0)
..but what when conference port doesn't exist?
when i want connect left/right channel to conference bridge with API
pjmedia_splitcomb_set_channel i need pjmedia_port..
when i want create conference port i need pjmedia_port too..
is possible get left/right channel from "splitcomb" like pjmedia_port? then
i can make port in bridge
or some other idea?
thanks
