Hi, I am trying to establish a session with audio and video with ICE and I am encountering an issue which causes the video not to flow properly My UA is sending the INVITE with audio and video. Both media sessions (audio and video) are setup as the controlling ICE agent. I n the log I can see the following log (which is for the audio session): 13:26:02.654 icetp00 . 0: [1] 10.4.4.253:54003-->10.4.4.201:5646 (nominated, state=Succeeded) 13:26:02.654 icetp00 . 1: [2] 10.4.4.253:59419-->10.4.4.201:5647 (nominated, state=Succeeded) 13:26:02.654 icetp00 ICE negotiation success after 1s:180 13:26:02.654 icetp00 Comp 1: sending from host candidate 10.4.4.253:54003 to host candidate 10.4.4.201:5646 13:26:02.654 icetp00 Comp 2: sending from host candidate 10.4.4.253:59419 to host candidate 10.4.4.201:5647 13:26:02.654 pjsua_media.c .ICE default transport address has changed for call 0, sending re-INVITE 13:26:02.655 pjsua_call.c .Sending re-INVITE on call 0 13:26:02.655 pjsua_core.c .....TX 2335 bytes Request msg INVITE/cseq=26893 (tdta0xf9a9600) to tls 10.4.4.201:5061: In the invite I can see that the remote-candidate is advertised for the audio session but not yet for the video. Shortly after I see something similar for the video session: 13:26:02.661 icetp01 . 0: [1] 10.4.4.253:59553-->10.4.4.201:5648 (nominated, state=Succeeded) 13:26:02.661 icetp01 . 1: [2] 10.4.4.253:63648-->10.4.4.201:5649 (nominated, state=Succeeded) 13:26:02.662 icetp01 ICE negotiation success after 1s:186 13:26:02.662 icetp01 Comp 1: sending from host candidate 10.4.4.253:59553 to host candidate 10.4.4.201:5648 13:26:02.662 icetp01 Comp 2: sending from host candidate 10.4.4.253:63648 to host candidate 10.4.4.201:5649 13:26:02.662 pjsua_media.c .ICE default transport address has changed for call 0, sending re-INVITE 13:26:02.663 pjsua_call.c .Sending re-INVITE on call 0 13:26:02.663 pjsua_call.c ..Unable to create re-INVITE: Invalid operation (PJ_EINVALIDOP) [status=70013] Note that this time the re-INVITE was not sent because we already have an offer pending and didn't yet get an answer from the remote agent. The end result is that the remote candidate for the video session is never advertised so video is not flowing. Audio is working fine.
