The Video player library for Sunbird platform!

The Video player library is powered by Angular. This player is primarily designed to be used on Sunbird consumption platforms (mobile app, web portal, offline desktop app) to drive reusability and maintainability, hence reducing the redundant development effort significantly, and it can be integrated with any platform irrespective of the platforms and the frontend frameworks. It is exported not only as an angular library but also as a web component. 

Getting Started with different integrations steps

The video player can be integrated as a web component and also as an angular library in angular application projects and it can also be integrated into any mobile framework as a web component.

Use as web components

Any web based application can use this library as a web component. It accepts player config as input and triggers player and telemetry events back to the application.

Import this library in any web application and use the custom component.

Follow below-mentioned steps to use it in plain javascript project:

  • Insert library as below:

     <script type="text/javascript" src="sunbird-video-player.js"></script>
  • Create a asset folder and copy all the files from here, library requires these assets internally to work well.

  • Get sample playerConfig from here: playerConfig

  • Pass the QuestionListAPI baseUrl if your content is interactive otherwise you can skip this step for eg.

     window.questionListUrl = 'https://staging.sunbirded.org/api/question/v1/list';
     window.questionSetBaseUrl = 'https://staging.sunbirded.org/api/questionset';
  • Create a custom html element: sunbird-video-player

     const  videoElement = document.createElement('sunbird-video-player');
  • Pass data using player-config

     videoElement.setAttribute('player-config', JSON.stringify(playerConfig));

    Note: Attribute should be in string type

  • Listen for the output events: playerEvent and telemetryEvent

     videoElement.addEventListener('playerEvent', (event) => {
     	console.log("On playerEvent", event);
     });
     videoElement.addEventListener('telemetryEvent', (event) => {
     	console.log("On telemetryEvent", event);
     });
  • Append this element to existing element

     const  myPlayer = document.getElementById("my-player");
     myPlayer.appendChild(qumlPlayerElement);
  • Refer demo example

Use as Web component in the Angular app

  • Run command

      npm i @project-sunbird/sunbird-video-player-web-component
      npm i reflect-metadata
  • Add these entries in angular json file inside assets, scripts and styles like below

              "assets": [
                "src/favicon.ico",
                "src/assets",
                {
                  "glob": "**/*.*",
                  "input": "./node_modules/@project-sunbird/sunbird-video-player-web-component/assets",
                  "output": "/assets/"
                }
              ],
              "styles": [
                "src/styles.scss",
                "node_modules/@project-sunbird/sunbird-video-player-web-component/styles.css"
              ],
              "scripts": [
                "node_modules/reflect-metadata/Reflect.js",
                "node_modules/@project-sunbird/sunbird-epub-player-web-component/sunbird-video-player.js"
              ]
    
  • Import CUSTOM_ELEMENTS_SCHEMA in app module and add it to the NgModule as part of schemas like below

    ...
    import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
    ...
    
    @NgModule({
     ...
     schemas: [CUSTOM_ELEMENTS_SCHEMA],
     ...
    })
  • Integrating sunbird-video-player web component in angular component

    Create a viewChild in html template of the angular component like

        <div #video></div>
    

    Refer the viewChild in ts file of the component and create the video player using document.createElement, then attach the player config and listen to the player and telemetry events like below and since we are rendering using viewChild these steps should be under ngAfterViewInit hook of the angular component.

....

@ViewChild('video') video: ElementRef;

  ....
 ngAfterViewInit() {
    const playerConfig = <Config need be added>;
      const epubElement = document.createElement('sunbird-video-player');
      epubElement.setAttribute('player-config', JSON.stringify(playerConfig));

      epubElement.addEventListener('playerEvent', (event) => {
        console.log("On playerEvent", event);
      });

      epubElement.addEventListener('telemetryEvent', (event) => {
        console.log("On telemetryEvent", event);
      });
      this.video.nativeElement.append(epubElement);
  }
  ....

Note: : Click to see the mock - playerConfig and send input config as string

Use as Angular library in angular app

Step 1: Installation

Just run the following:

ng add @project-sunbird/sunbird-video-player-v9

It will install sunbird-video-player for the default application specified in your angular.json. If you have multiple projects and you want to target a specific application, you could specify the --project option

ng add @project-sunbird/sunbird-video-player-v9 --project myProject

Manual installation

If you prefer not to use schematics or want to add sunbird-video-player-v9 to an older project, you'll need to do the following:
