WEBRTC-在将答案设置到setLocalDescription中时,在firefox beta版本.63中出现以下错误
this.soc.setLocalDescription(answer,function(){},function(error){co.handleAnswerLoacalDescError(error);});
SWRTCAnswerPConn.prototype.handleAnswerLoacalDescError =函数(错误){ console.log(“ error SWRTCAnswerPConn.prototype.handleAnswerLoacalDescError” + error); }
下面是本地sdp
