Hi guys, With Pjsip I’m trying to connect with a multicast channel/ipAddress (I should receive and transmit audio on defined idAddress). According with streamutil.c I have wrote the following c++ function but It’s not working: pj_status_t ApplicationCore::multicastConnection() { intLogger->log(InternalLogger::LOG_INFO, "MULTICAST CONNECTION"); pjmedia_stream **p_stream; pjmedia_endpt *med_endpt; pj_caching_pool cp; pj_status_t status; pjmedia_stream *stream = NULL; pj_uint16_t local_port = 3000; const pjmedia_codec_info *codec_info; const pj_sockaddr_in *rem_addr; /* Must create a pool factory before we can allocate any memory. */ pj_caching_pool_init(&cp, &pj_pool_factory_default_policy, 0); /* * Initialize media endpoint. * This will implicitly initialize PJMEDIA too. */ status = pjmedia_endpt_create(&cp.factory, NULL, 1, &med_endpt); PJ_ASSERT_RETURN(status == PJ_SUCCESS, 1); pjmedia_stream_info info; pjmedia_transport *transport = NULL; //Reset stream info pj_bzero(&info, sizeof(info)); //Initialize stream info formats info.type = PJMEDIA_TYPE_AUDIO; //info.dir = dir; pj_memcpy(&info.fmt, codec_info, sizeof(pjmedia_codec_info)); info.tx_pt = codec_info->pt; info.rx_pt = codec_info->pt; info.ssrc = pj_rand(); pj_memcpy(&info.rem_addr, rem_addr, sizeof(pj_sockaddr_in)); //239.0.0.1 multicast channel const pj_str_t multicastAddrIpv4 = pj_str("239.0.0.1"); status = pj_sockaddr_in_init(&info.rem_addr.ipv4, &multicastAddrIpv4, 0); if(status != PJ_SUCCESS) { intLogger->log(InternalLogger::LOG_CRITICAL, "initialize IPv4 socket address failed"); return status; } //Create media transport status = pjmedia_transport_udp_create(med_endpt, NULL, local_port, 0, &transport); if(status != PJ_SUCCESS) { intLogger->log(InternalLogger::LOG_CRITICAL, "pjmedia transport udp create failed"); return status; } status = pjmedia_stream_create( med_endpt, pool, &info, transport, NULL, p_stream); if (status != PJ_SUCCESS) { intLogger->log(InternalLogger::LOG_CRITICAL, "error creating stream"); pjmedia_transport_close(transport); return status; } //Start streaming pjmedia_stream_start(stream); return PJ_SUCCESS; } How can I implement this function in the right mode? Thanks in advice. Best Regards LL |
