xelven commented 8 years ago

I think there have other issue relate to libNice, Since I try to figure out the root cause of my posted issue, ref: https://github.com/EricssonResearch/openwebrtc/issues/575

so I enable the G_MESSAGES_DEBUG & NICE_DEBUG to all.

but I found if the connection has connected one once, then hangup by UI drive to reset() OpenWebRTCHandle from iOS-SDK, then as the NICE_DEBUG log are still try to connecting peer all the time.

here is the info of the pair candidate

I would like take look whats wrong between OpenWebRTC and LibNice, so let discuss on this. I plan make an example for NICE first, and then take look it from OpenWebRTC.

if some one has been experience on libNice, please let's talk!

well, I think I got it, this is the bug in OWR, as the document of Nice, there function called nice_agent_add_stream by add session, But there nobody call nice_agent_remove_stream, nobody.

Just tried, and it works. No more connection running in background after reset. done.

Hi Allen,

would you be willing to provide a Pull Request to fix this in OWR so that others can benefit?

Thanks, Stefan
