A Streamer is a server accepting a stream of UDP packets on one port (incoming port) and allowing multiple clients to connect on a different port (outgoing port) and receive that stream.
The server listens for an incoming stream on a port defined by a command line argument incoming-port. Any packet received on this port is immediately sent to the all connected client.
The server listens for client connections on a port defined by a command line argument outgoing-port. Clients communicate with the server using the protocol defined below:
CONNECT id - connect to server and start receiving the stream
DISCONNECT id - disconnect from server
ALIVE id - notify server that connection is alive. Failing to send this for 30 seconds will cause the server to disconnect that client. Usually a client will send this every 10 seconds.
(id is a an arbitrary identifier per connection)
