myAtem.connect('192.168.168.240')
myAtem.on('connected', () => {
myAtem.changeProgramInput(3).then((res) => {
console.log(res)
// ProgramInputCommand {
// flag: 0,
// rawName: 'PrgI',
// mixEffect: 0,
// properties: { source: 3 },
// resolve: [Function],
// reject: [Function] }
})
console.log(myAtem.state)
})
myAtem.on('stateChanged', function(err, state) {
console.log(state); // catch the ATEM state.
});
connected
This event will be fired once we have connected with the ATEM.
disconnected
Whenever the connection to the ATEM fails and does not recover within 5 seconds this is called.
stateChanged(state)
Whenever a packet from the ATEM is received that changes the state, this event will be fired.
Set debug=true config option in order to see raw packets. This is especially useful for library developers.
const myAtem = new Atem({ debug: true, externalLog: console.log })
