       rtmpsuck - a transparent RTMP proxy


       rtmpsuck [-z]


       rtmpsuck  is  a transparent RTMP proxy. It listens on port 1935 for RTMP sessions, but you
       can also redirect other ports to it as needed. It first performs an  RTMP  handshake  with
       the client, then waits for the client to send a connect request.  It parses and prints the
       connect parameters, then makes an outbound connection to the real RTMP server. It performs
       an  RTMP  handshake with that server, forwards the connect request, and from that point on
       it just relays packets back and forth between the two endpoints.
       It also checks for a few packets that it treats specially: a play packet from  the  client
       will  get  parsed  so that the playpath can be displayed. It also handles SWF Verification
       requests from the server, without forwarding them to the client.
       Once the play command is processed, all subsequent  audio/video  data  received  from  the
       server will be written to a file, as well as being delivered back to the client.
       The  point  of  all  this,  instead  of  just  using a sniffer, is that since rtmpsuck has
       performed real handshakes with both the client and the server, it can  negotiate  whatever
       encryption keys are needed and so record the unencrypted data.


       -z Debug level output. Extremely verbose.
