PlayoutStatus

The station's transport, as one reading

Attributes (11)

Attribute	Type	Required	Description
streamUp	boolean	Yes	Whether Liquidsoap's control API is answering at all. False means nothing can air, whatever the running order holds
onAir	boolean	Yes	Whether the station is actually broadcasting. deadair holds the mount on a lease it renews only while it has a programme, so a reachable stream with nothing to play is up and NOT on air: it is connected, and airing silence
mountPath	string	Yes	Same-origin path of the Icecast MP3 mount, which is always published and is the one a console names when it can only name one. A path rather than a URL: the browser reaches Icecast through whatever edge served the SPA, never at the address the app itself uses
mounts	PlayoutMount[]	Yes	Every mount being published, MP3 first, so a console can offer the others rather than implying the station is only on one. Never empty: MP3 has no switch. A format the operator has not switched on is absent rather than present and disabled, because every consumer of this wants the mounts that are actually there
nowPlaying	PlayoutNowPlaying	No
upNext	PlayoutItem[]	Yes	Waiting here, in order. Excludes what the player already holds
queuedCount	number	Yes	How many items are waiting in total, of which upNext is the head
listeners	number	Yes	How many clients Icecast has attached to the mount. Zero both for "nobody is listening" and for an Icecast that is not answering, which audience is where to tell apart
audience	boolean	Yes	Whether the station counts as having an audience, which lingers for a minute past the last listener so a reconnecting player does not cut the broadcast
staleStreamConfig	StreamConfigWarning[]	Yes	Containers running config the app has since replaced. Empty is the ordinary state, and so is empty for anything the app has no evidence about: a warning here has never been a guess
silence	StationSilence	Yes	Which gate is keeping the station quiet, composed from every one of them rather than inferred from the fields above. streamUp, onAir, audience and queuedCount each answer for one gate and a console reading them alone has to guess at the rest
