What does this webrtc warning mean?
When trying to establish a video + audio connection using the built- webRTC
in iOS7
, the following warning appears.
Warning (webrtcsession.cc:1423): The candidate has an unknown component: cand [3902756006: 2: udp: 2122063615: 192.168.178.26: 59273: local :: 0 ::] for content: audio
I get it several times, some with audio at the end, some with video. I can currently establish a connection and receive audio from both ends. The video is being sent (not 100% sure), but not yet received (the screen is displayed in black).
My environment:
- Testing on iPad3 and iPad4
- Both are running the latest iOS
- Development using Xcode version 5.1.1 (5B1008)
- I have my own signaling server hosted on my local network
- I am using a queue server hosted on my local network (same device as the signaling server).
- My complete log on running an app to get sound at both ends can be found here

These warnings are related to calling WebRTC methods for different threads, while all calls to the library must be performed in the same thread. I've had success with everything on one background thread as well as on the main thread, albeit throughout the entire lifecycle of the application.
