.

Establishing a connection

Establish a TCP connection with the server, and send the payload. If the server likes your payload, it will stream data to you, or accept more of your data.

The payload

Send a UTF-8 string identifying the client's intentions. Fill the request with trailing spaces until the request is 1000 bytes.

watch,fier,123 - Watch fier's stream, supplying 123 as the watch password (optional). It will blast you with the media data.
broadcast,fier,123 - Broadcast as fier, supplying 123 as the broadcast password, as configured on the server. May be optional if not set. Just blast the data to the server after this.
