The RTCError will be thrown by RTCPeerConnection.setLocal/RemoteDescription, RTCRtpSender.setParameters() and RTCDataChannel.onerror. Currently these APIs sometimes throw the wrong exception/error. The RTCError object provides additional information about an error, such as WebRTC-specific error codes or which line an SDP parsing error occurred.
