sdp-example sometimes not work
I use master branch, latest code. All of the tests run on the same computer. After build libnice, I open two terminal, one run ./examples/sdp-example 0 and the other run ./examples/sdp-example 1. Sometimes, it works well. But sometimes, "Send lines to remote (Ctrl-D to quit):" is not shown, and I found "SIGNAL: state changed 1 1 failed" in log. I don't know how to fix it, is there any wrong with my steps? The log is attached, thank you.
