[sr-dev] git:master: modules/rtpproxy: rtpproxy_manage can now add ice relay candidates

[Ovidiu Sas]

Hello Juha,

The relay candidate is added only for RTP stream, but not for RTCP stream.
Example:
received SDP:
v=0.
o=- 3569961501 3569961501 IN IP4 192.168.2.104.
s=cpc_med.
c=IN IP4 192.168.2.104.
t=0 0.
m=audio 53528 RTP/AVP 0 101.
a=sendrecv.
a=rtpmap:0 PCMU/8000.
a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-15.
a=ice-ufrag:3d6687c0.
a=ice-pwd:165a6dbe.
a=candidate:Hc0a80268 1 UDP 2130706431 192.168.2.104 53528 typ host.
a=candidate:Hc0a80268 2 UDP 2130706430 192.168.2.104 49908 typ host.

sent SDP:
v=0.
o=- 3569961501 3569961501 IN IP4 192.168.2.2.
s=cpc_med.
c=IN IP4 192.168.2.2.
t=0 0.
m=audio 11070 RTP/AVP 0 101.
a=sendrecv.
a=rtpmap:0 PCMU/8000.
a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-15.
a=ice-ufrag:3d6687c0.
a=ice-pwd:165a6dbe.
a=candidate:Hc0a80268 1 UDP 2130706431 192.168.2.104 53528 typ host.
a=candidate:19216822 1 UDP 16777215 192.168.2.2 11070 typ relay.
a=candidate:Hc0a80268 2 UDP 2130706430 192.168.2.104 49908 typ host.

We should have an extra candidate:
a=candidate:19216822 1 UDP 16777215 192.168.2.2 11071 typ relay.

rtpproxy will allocate an extra port for RTCP traffic (RTP port + 1).

Regards,
Ovidiu Sas
