Hi, My video call application using libnice and turn server for symmetric NAT traversal. In some case, I can gather relay server for both video and audio like below sdp: v=0 o=- 2184017736251815492 8580066925214433698 IN IP4 192.168.1.41 s=- t=0 0 m=video 33993 RTP/AVP 98 c=IN IP4 192.168.1.41 a=rtpmap:98 theora/90000 a=candidate:1 1 UDP 2013266431 192.168.1.41 33993 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 39193 typ host a=candidate:3 1 UDP 1677721855 210.245.54.74 60885 typ srflx a=candidate:4 1 UDP 1006633215 83.150.122.225 55671 typ relay a=ice-pwd:7SBrRWChu2A3z+hsKpNN0r a=ice-ufrag:bdDn a=rtcp:0 m=audio 38143 PCMU/AVP 0 c=IN IP4 192.168.1.41 a=rtpmap:0 PCMU/8000 a=candidate:1 1 UDP 2013266431 192.168.1.41 38143 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 48049 typ host a=candidate:3 1 UDP 1677721855 210.245.54.74 61047 typ srflx a=candidate:4 1 UDP 1006633215 83.150.122.225 62630 typ relay a=ice-pwd:Pqc3Or66wkjS+wN6z73ww8 a=ice-ufrag:m9AG a=rtcp:0 but in another time, I only gather relay server for audio or video or nothing: v=0 o=- 8769129355780658083 7584008823329948515 IN IP4 192.168.1.41 s=- t=0 0 m=video 52520 RTP/AVP 98 c=IN IP4 192.168.1.41 a=rtpmap:98 theora/90000 a=candidate:1 1 UDP 2013266431 192.168.1.41 52520 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 41380 typ host a=candidate:3 1 UDP 1677721855 210.245.54.74 61557 typ srflx a=candidate:4 1 UDP 1006633215 83.150.122.225 59608 typ relay a=ice-pwd:fHBGxclzwZqz6fNl+PdAYI a=ice-ufrag:0GRT a=rtcp:0 m=audio 58936 PCMU/AVP 0 c=IN IP4 192.168.1.41 a=rtpmap:0 PCMU/8000 a=candidate:1 1 UDP 2013266431 192.168.1.41 58936 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 50804 typ host a=ice-pwd:GmuIDz7o9IHVLxqhr52JeM a=ice-ufrag:dX+Z a=rtcp:0 ================================================================= v=0 o=- 4016385316294493094 2686950318062895343 IN IP4 192.168.1.41 s=- t=0 0 m=video 46895 RTP/AVP 98 c=IN IP4 192.168.1.41 a=rtpmap:98 theora/90000 a=candidate:1 1 UDP 2013266431 192.168.1.41 46895 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 38023 typ host a=ice-pwd:2EOBEvTTpL/e88j2ymvd6f a=ice-ufrag:IIX4 a=rtcp:0 m=audio 57581 PCMU/AVP 0 c=IN IP4 192.168.1.41 a=rtpmap:0 PCMU/8000 a=candidate:1 1 UDP 2013266431 192.168.1.41 57581 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 48726 typ host a=ice-pwd:WGag9CGVWa4UpCJ6Myeyto a=ice-ufrag:LgYu a=rtcp:0 ================================================================== v=0 o=- 8900533634173556908 2270264087450858543 IN IP4 192.168.1.41 s=- t=0 0 m=video 47791 RTP/AVP 98 c=IN IP4 192.168.1.41 a=rtpmap:98 theora/90000 a=candidate:1 1 UDP 2013266431 192.168.1.41 47791 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 33952 typ host a=ice-pwd:+jft1vZC9UNJg//cgrFzSn a=ice-ufrag:fnyD a=rtcp:0 m=audio 39922 PCMU/AVP 0 c=IN IP4 192.168.1.41 a=rtpmap:0 PCMU/8000 a=candidate:1 1 UDP 2013266431 192.168.1.41 39922 typ host a=candidate:2 1 UDP 2013266431 192.168.2.14 58084 typ host a=candidate:3 1 UDP 1677721855 210.245.54.74 63425 typ srflx a=candidate:4 1 UDP 1006633215 83.150.122.225 55358 typ relay a=ice-pwd:JqbJd1xHYFkkIK6U9B7BL3 a=ice-ufrag:G93f a=rtcp:0 I'm using seperate turn server with ## Max relay per username. max_relay_per_username = 10 ## Allocation lifetime. allocation_lifetime = 360 And my source code : self->v_stream_id=nice_agent_add_stream(self->v_agent,1); nice_agent_set_relay_info(self->v_agent,self->v_stream_id,NICE_COMPONENT_TYPE_RTP, NUMB_IP,NUMB_PORT,NUMB_USER,NUMB_PASS,NICE_RELAY_TYPE_TURN_UDP); nice_agent_gather_candidates(self->v_agent,self->v_stream_id); nice_agent_attach_recv(self->v_agent,self->v_stream_id,NICE_COMPONENT_TYPE_RTP, g_main_context_default(),cb_nice_v_recv, self); self->a_stream_id=nice_agent_add_stream(self->a_agent,1); nice_agent_set_relay_info(self->a_agent,self->a_stream_id,NICE_COMPONENT_TYPE_RTP, NUMB_IP,NUMB_PORT,NUMB_USER,NUMB_PASS,NICE_RELAY_TYPE_TURN_UDP); nice_agent_gather_candidates(self->a_agent,self->a_stream_id); nice_agent_attach_recv(self->a_agent,self->a_stream_id,NICE_COMPONENT_TYPE_RTP, g_main_context_default(),cb_nice_a_recv, self); After gathering done: local_cands=nice_agent_get_local_candidates(self->v_agent,self->v_stream_id,c_id); ... and local_cands=nice_agent_get_local_candidates(self->a_agent,self->a_stream_id,c_id); ... Can anyone help me to gather relay server all time ? |
