The file

The top level accepts three lists:

{
  "cams": [],
  "videoMixers": [],
  "interfaces": []
}

What every entry carries

Key	Means
type	which builder claims the entry, and therefore which other keys it accepts
instance	a positive number the rest of the file refers to this entry by

instance is unique within its list. Cameras and mixers may share a number. Interfaces reference mixers through videoMixer and cameras through cameraMap.

{
  "cams":        [ { "type": "viscaoverip", "instance": 7, "ip": "10.0.0.4" } ],
  "videoMixers": [ { "type": "passthrough/default", "instance": 1 } ],
  "interfaces":  [ { "type": "keyboard", "instance": 1, "videoMixer": 1,
                     "cameraMap": { "3": 7 } } ]
}

Mixer input 3 maps to camera 7.

When an entry is wrong

Invalid entries are logged and skipped independently. Errors name the entry and property:

viscaoverip[7].port: expected a number in ]0 .. 65535], found 70000

Unknown properties are errors.

Loaded cameras and mixers appear in the window even if no interface references them.
