The API reference on our website (or built using make doc) is supposed
to give you all details. But it appears that you just spotted a bug:
we abusively strip parameters called "type"!!! I know what's wrong
here, I should fix it soon (I've created a ticket).

True, this is not a pure liquidsoap setup (that may be possible, but
it's probably not the best option) but liquidsoap should make it easy.
If I understand well your question, you have an input.http() or
input.harbor() and you want to control when the main script replays
it. (You also want to monitor, so input.http is simpler.) What you
need is to wrap that live source in an operator that controls when it
is available, before putting that in a fallback/switch/etc.
A first possibility is to use a switch which relies on a reference
that is set from the server:
enabled = ref false
def enable()
enabled := true
"OK"
end
server.register("enable",enable)
def disable()
enabled := false
"OK"
end
server.register("disable",disable)
s = switch([({!enabled},s)])
Now the new definition of s only appears to be ready when enabled says
so. However, that solution does not allow to interrupt a track by
disabling.
The other option is to use mix() which is more powerful. Just use s =
mix([s]) and then use the server command associated with mix to
control the volume and availability of s.
Cheers,
David
