Video player library for Sunbird platform!

Contains Video player library components powered by angular. These components are designed to be used in sunbird consumption platforms (mobile app, web portal, offline desktop app) to drive reusability, maintainability hence reducing the redundant development effort significantly.

Getting Started

For help getting started with a new Angular app, check out the Angular CLI. If you have an Angular ≥ 9 CLI project, you could simply use our schematics to add sunbird-video-player library to it.

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:

1. Install the packages:

  npm install @project-sunbird/sunbird-video-player-v9 --save
  npm install @project-sunbird/sunbird-quml-player-v9 --save
  npm install @project-sunbird/sb-styles --save
  npm install @project-sunbird/client-services --save
  npm install lodash-es --save
  npm install ngx-bootstrap --save
  npm install jquery --save
  npm install video.js --save
  npm install videojs-contrib-quality-levels --save
  npm install videojs-http-source-selector --save

2: Include the styles, scripts and assets in angular.json

"styles": [
...
...
"src/styles.css",
"./node_modules/@project-sunbird/sb-styles/assets/_styles.scss",
"./node_modules/video.js/dist/video-js.min.css",
"./node_modules/@project-sunbird/sunbird-video-player-v9/lib/assets/videojs.markers.min.css",
"./node_modules/videojs-http-source-selector/dist/videojs-http-source-selector.css"
],
"scripts": [
...
...
"node_modules/jquery/dist/jquery.min.js",
"node_modules/video.js/dist/video.js",
"node_modules/@project-sunbird/sunbird-video-player-v9/lib/assets/videojs-markers.js",
"node_modules/videojs-contrib-quality-levels/dist/videojs-contrib-quality-levels.min.js",
"node_modules/videojs-http-source-selector/dist/videojs-http-source-selector.min.js"
]

Add following under architect.build.assets

 {
    ...
    "build": {
    
    "builder": "@angular-devkit/build-angular:browser",
    
    "options": {
	    ...
	    ...

	    "assets": [
	    
		   ...
		   ...
		    
		    {
			    "glob": "**/*.*",
			    "input": "./node_modules/@project-sunbird/sunbird-video-player-v9/lib/assets/",
			    "output": "/assets/"
		    },
      {
            "glob": "**/*",
            "input": "node_modules/@project-sunbird/sunbird-quml-player-v9/lib/assets/",
            "output": "/assets/"
      }
	    
	    ],

    "styles": [
    
    ...
    
    "./node_modules/@project-sunbird/sb-styles/assets/_styles.scss",
    "./node_modules/video.js/dist/video-js.min.css",
    "./node_modules/@project-sunbird/sunbird-video-player-v9/lib/assets/videojs.markers.min.css",
    "./node_modules/videojs-http-source-selector/dist/videojs-http-source-selector.css"
    ],
    "scripts": [
     ...
     "node_modules/jquery/dist/jquery.min.js",
     "node_modules/video.js/dist/video.js",
     "node_modules/@project-sunbird/sunbird-video-player-v9/lib/assets/videojs-markers.js",
     "node_modules/videojs-contrib-quality-levels/dist/videojs-contrib-quality-levels.min.js",
     "node_modules/videojs-http-source-selector/dist/videojs-http-source-selector.min.js",
     "dist/sunbird-video-player/lib/assets/videojs-transcript-click.min.js"
     ]
    ...
    ...

},

Step 2: Import the modules and components

Import the NgModule where you want to use. Also create a question-cursor-implementation.service

    import { SunbirdVideoPlayerModule } from '@project-sunbird/sunbird-video-player-v9';
    import { QuestionCursor } from '@project-sunbird/sunbird-quml-player-v9';
    import { QuestionCursorImplementationService } from './question-cursor-implementation.service';

    
    @NgModule({
	    ...
	    
	    imports: [SunbirdVideoPlayerModule],
	    providers: [{ provide: QuestionCursor, useClass: QuestionCursorImplementationService }],
	    
	    ...
    })

  
    export class TestAppModule { }

  

Step 3: Send input to render VIDEO player

Use the mock config in your component to send input to VIDEO player Click to see the mock - playerConfig

Player config

var playerConfig = {
  "context": {
    "mode": "play",  // To identify preview used by the user to play/edit/preview
    "authToken": "", // Auth key to make  api calls
    "sid": "7283cf2e-d215-9944-b0c5-269489c6fa56", // User sessionid on portal or mobile

    "pdata": {
      "id": "sunbird.portal", // Producer ID. For ex: For sunbird it would be "portal" or "genie"
      "ver": "3.2.12", // Version of the App
      "pid": "sunbird-portal.contentplayer" // Optional. In case the component is distributed, then which instance of that component
    },
    "contextRollup": { // Defines the content roll up data
      "l1": "505c7c48ac6dc1edc9b08f21db5a571d"
    },
    "tags": [ // Defines the tags data
      ""
    ],

    }
  },
  "config": { 
	"traceId": "afhjgh", // Defines trace id
    "sideMenu": { 
      "showShare": true,    // show/hide share button in side menu. default value is true

      "showReplay": true, // show/hide replay button in side menu. default value is true
      "showExit": true,   // show/hide exit button in side menu. default value is true
    },
       // tslint:disable-next-line:max-line-length
    "transcripts": [] // for default selection we need this , ex: ['kn', 'en'] the last element in the array will be used for default selection and no need of default selection than no need send this in config or send empty array [] or ['off'] 
  },
  "metadata": { // Content metadata json object (from API response take -> response.result.content)
  "transcripts": [] // Defines the details of the transcripts data array and each object in array conatins details of language,languageCode, identifier, artifactUrl of each transcript
  }, 
}

Mobile app integration steps

For existing apps, follow these steps to begin using.

Step 1: Install the packages

Click to see the steps - InstallPackages

Step 2: Include the sb-styles and assets in angular.json

Click to see the steps - IncludeStyles , but use src/global.scss instead of src/styles.css in styles.

Step 3: Import the modules and components

Click to see the steps - Import

Step 4: Import in component

 <sunbird-video-player [playerConfig]="playerConfig" (playerEvent)="playerEvents($event)"
  (telemetryEvent)="playerTelemetryEvents($event)"></sunbird-video-player> 

Note : An additional property named action can be added to the above statement to implement pause and play functionality for the video player.

Step 5: Send input to render VIDEO player

Use as web components

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 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
