Centoplayer App SDK

Development

• run with: npm start
• browse to /test subdirectory on: http://127.0.0.1:8080

Getting started

npm i @dgtgroup/centoplayer-sdk

import { CentoSDK } from '@dgtgroup/centoplayer-sdk';

// Wait for initialization & Cento-player info:
CentoSDK.on('initialized', (playerInfo: Cento.Info) => {
  console.log('🟢 CENTO-SDK IS INITIALIZED');
  console.log('🟢', playerInfo);
});

Angular implementation

As the SDK emits events that are outside of Angular's Zone, they do not get picked up by Angular's change Detection. In case a rerender is required, use ngZone.run() to trigger change detection:

CentoSDK.on('methodname', () => {
  this.ngZone.run(() => {
    this.myCustomFunction(value);
  });
});

Available methods

Implemented

centoSDK.getPlatform() Returns the current platform information: webos, centoplayer (=linux), DEVMODE

centoSDK.getSerialNumber() Returns the serial number of the device.

centoSDK.getPlayerInfo() Returns information about the media player as a Cento.Info object.

centoSDK.playlistStop(preload?:boolean) centoSDK.playlistStart() Starts or stops the current playlist. Preload option will prepare the next item in the playlist for instant playback.

Note: WebOS supports playback of only one video at a time. Starting a new video will automatically stop any currently playing video across the entire Signage Player. Ensure you stop any playing video before starting a new one in your application.

Awaiting implementation

centoSDK.reboot() centoSDK.refresh() centoSDK.displayOn() centoSDK.displayOff() centoSDK.showConsole() centoSDK.hideConsole() centoSDK.getVolume() centoSDK.setVolume(value: number) centoSDK.openPlayerUI() centoSDK.showKeyboard() centoSDK.hideKeyboard()

Events

centoSDK.on('initialized', (playerinfo: Cento.Info)=>{ ... }) centoSDK.on('serial', (value:string)=>{ ... }) centoSDK.on('keydown', (e:KeyboardEvent)=>{ ... }) centoSDK.on('keyup', (e:KeyboardEvent)=>{ ... })

Serial Communication

Listening to Serial Input events (eg. qrcode scanner):

onSerial(value: string) {
  console.log('Scanned value:', value);
}
const bind = this.onSerial.bind(this);

CentoSDK.on('serial', bind);
CentoSDK.off('serial', bind);

Keyboard events

centoSDK.on('keydown', (evt: KeyboardEvent) => {
  console.log('Key-down event:', evt);
});
centoSDK.on('keyup', (evt: KeyboardEvent) => {
  console.log('Key-up event:', evt);
});
