class virtual output : content_kind:Frame.content_kind -> output_kind:string -> ?name:string -> infallible:bool -> on_start:(unit -> unit) -> on_stop:(unit -> unit) -> Lang.value -> bool -> object .. end
Given abstract start stop and send methods, creates an output.
Takes care of pulling the data out of the source, type checkings,
maintains a queue of last ten metadata and setups standard Server commands,
including start/stop.

An infallible (normal) output can always stream.
Both fallible and infallible outputs may not always be outputting
(sending data to the world using #output_send).
Outputting can only be done when streaming.
The following two methods give those two aspects of the current status,
#is_active tells if the source is outputting and #is_ready tells
whether it is streaming or can start streaming.
