先创建设置： // Prepare the configuration
config := webrtc.Configuration{
ICEServers: []webrtc.ICEServer{

之前的几个案例中，ICE过程中SDP的传输都是手工复制粘贴完成的，没有显式指定监听端口的过程，而pion-to-pion就提供了一种自动传输SDP交互的方式。在pion-to-pion里面，pion双方都在固定的端口监听POST请求，SDP信息生成好了之后是用POST传给对方的。 pion-to-p
// Assert that we have an audio or video file
_, err := os.Stat(videoFileName)
haveVideoFile := !os.IsNotExist(err)
_, err = os.Stat(audioFileName)
