Hi Benny et al, it's my first time here in the mailing list, even if I've been reading your precious suggestions for 2 months. I like so much your software and its flexibility. I've to develop an application that should split/comb a G711 pcma 16 channels (custom pjmedia port) and do separately RTP streaming for each channel. It's just a media flow, let assume that all remote addresses are hard coded at the moment. I started from the streamutil.c code and also tried to use your comments here: http://trac.pjsip.org/repos/wiki/FAQ#pjsua-lib-perf I successfully streamed 1 single channel from the custom port. I'm trying now with 2 channels, the application start streaming but on remote sites there is only silence. What I did is the following (added to streamutil): Custom port and splitcomb creation: - create_pcm_port(pool, 8000, 2, &pcm_port) - pjmedia_splitcomb_create(..., &splitcomb_port) To connect custom port to splitcomb: - pjmedia_conf_create(...,PJMEDIA_CONF_NO_DEVICE, &pcm_conf_port) - pjmedia_conf_add_port(pcm_conf_port, pool, pcm_port, NULL, &slot1) - pjmedia_conf_add_port(pcm_conf_port, pool, splitcomb_port, NULL, &slot2) - pjmedia_conf_connect_port(pcm_conf_port, slot1, slot2, 0) To streamout channel 1: - pjmedia_conf_create(...,PJMEDIA_CONF_NO_DEVICE, &pcmch1_conf) - pcmch1_mp=pjmedia_conf_get_master_port(pcmch1_conf) - pjmedia_splitcomb_set_channel(splitcomb_port, 0, 0, pcmch1_mp) - pjmedia_master_port_create(pool, pcmch1_mp, stream_port1, &master_port1) - pjmedia_master_port_start(master_port1) - pjmedia_stream_start(stream1) Does anybody know what's wrong in my pseudo-code? Thanks a lot, Fabio
