Two server programs rtmpsrv and rtmpsuck have been added since v2.1.
rtmpsrv is a stub for a server; it logs the connect and play parameters from a regular client that connects to it. It then invokes rtmpdump with those parameters to retrieve the stream.

rtmpsuck is a transparent proxy; it intercepts connections from a client and then makes an outbound connection to the real server. After all handshaking is complete and encryption keys with both sides are negotiated, it records the cleartext stream data into files while relaying the data from the server to the client.
