Hi Lele, if you set splitcomb like this: /* Connect channel0 (left channel) to conference port slot0 */ status = pjmedia_splitcomb_set_channel(sc, 0
/* ch0 */, 0
/*options*/, conf); status = pjmedia_splitcomb_create_rev_channel(pool, sc, 1
/* ch1 */, 0
/* options */, &sc_ch1); status = pjsua_conf_add_port(pool, sc_ch1, &sc_ch1_slot); and after creating wav player connect it to conference bridge like this: status = pjsua_conf_add_port(pool, file_port, &file_slot); then you have following ports in conference bridge: 0 = left sc_ch1_slot = right file_slot = wav player Now connect wav audio to left channel like this: pjsua_conf_connect(file_slot, 0); Best regards Adam Von: pjsip [mailto:pjsip-bounces@xxxxxxxxxxxxxxx]
Im Auftrag von Lele Hi guys, I’m working on pjmedia split audio channel left/right and I have the following issue. I don’t know how to send audio from wav audio file only on left channel of default my audio device. My source code is: //Test split left right channel pjmedia_snd_port *snd; pjmedia_port *sc, *sc_ch1; pjsua_conf_port_id sc_slot, sc_ch1_slot; pjmedia_port *conf; pj_status_t status; /* Disable existing sound device */ conf = pjsua_set_no_snd_dev(); /* Create stereo-mono splitter/combiner */ status = pjmedia_splitcomb_create( pool, PJMEDIA_PIA_SRATE(&conf->info)
/* clock rate */, 2
/* stereo */, 2 * PJMEDIA_PIA_SPF(&conf->info), PJMEDIA_PIA_BITS(&conf->info), 0
/* options */, &sc); pj_assert(status ==
PJ_SUCCESS); /* Connect channel0 (left channel) to conference port slot0 */ status = pjmedia_splitcomb_set_channel(sc, 1
/* ch1 */, 0
/*options*/, conf); pj_assert(status ==
PJ_SUCCESS); /* Create reverse channel for channel1 (right channel?)... */ status = pjmedia_splitcomb_create_rev_channel(pool, sc, 0
/* ch0 */, 0
/* options */, &sc_ch1); pj_assert(status ==
PJ_SUCCESS); status = pjsua_conf_add_port(pool, sc_ch1, &sc_ch1_slot); pj_assert(status ==
PJ_SUCCESS); pj_caching_pool cp; pj_pool_t *poolAs; pjmedia_port *file_port; pjmedia_snd_port *snd_port; /* Must create a pool factory before we can allocate any memory. */ pj_caching_pool_init(&cp, &pj_pool_factory_default_policy, 0); /* Create memory pool for our file player */ poolAs = pj_pool_create(&cp.factory,
/* pool factory */
"wav",
/* pool name. */
4000,
/* init size */
4000,
/* increment size */
NULL
/* callback on error */); /* Create file media port from the WAV file */ status = pjmedia_wav_player_port_create(pool,
/* memory pool */
"testSound.wav",
/* file to play */
20,
/* ptime. */
0,
/* flags */
0,
/* default buffer */
&file_port/* returned port */
); if (status !=
PJ_SUCCESS) { error("Unable to use WAV file",
status); } /* Create sound player port. */ status = pjmedia_snd_port_create_player(poolAs,
/* pool */ -1,
/* use default dev. */ PJMEDIA_PIA_SRATE(&file_port->info),/*
clock rate. */ PJMEDIA_PIA_CCNT(&file_port->info),/*
# of channels. */ PJMEDIA_PIA_SPF(&file_port->info),
/* samples per frame. */ PJMEDIA_PIA_BITS(&file_port->info),/*
bits per sample. */ 0,
/* options */ &snd
/* returned port */ );
if (status !=
PJ_SUCCESS) { error("Unable to open sound
device", status); }
/* Connect file port to the sound player.
status = pjmedia_snd_port_connect(snd, file_sc);
/* * File should be playing and looping now, using sound device's thread. */
/* Sleep to allow log messages to flush */ pj_thread_sleep(100); How can I solve the issue? Thanks in advice. Best regards Ll DFS Deutsche Flugsicherung GmbH Tel.: +49-(0)6103-707-0 Sitz der Gesellschaft: Langen/Hessen Internet: http://www.dfs.de |
