Creates an RTMP ingest Media Node. On creation, the Media Node is idle and your code must send an RtmpServerInputConfiguration message to configure the RTMP server. When a remote client connects, an RtmpConnection message is sent, which the code can choose to accept – by sending an RtmpConnectionAccept message or reject – by sending an RtmpConnectionReject message. Once a connection is established, Norsk will continue to send appropriate RtmpServerInputEvent messages as events occur.
