Hi I want to attach second audio device to conference bridge. Device 1 headset, device 2 loudspeakers. I tried: // create sound port status = pjmedia_snd_port_create(pjsua_var.pool, rec_id2, play_id2, clock_rate, channel_count, samples_per_frame, bits_per_sample, 0, &snd_port); // connect sound port to media port status = pjmedia_snd_port_connect( snd_port, media_port ); // connect media port to conference bridge status = pjmedia_conf_add_port(pjsua_var.mconf, pjsua_var.pool, media_port, NULL, NULL); But how to create a second media port? status = pjmedia_null_port_create(pjsua_var.pool, clock_rate, channel_count, samples_per_frame, bits_per_sample, &media_port); does not work... Any idea? Michael. ??? ??? -------------- next part -------------- An HTML attachment was scrubbed...
