FloSports Angular Media Source Extensions

A cross platform HTML 5 Media Source Extensions interface for Angular.

Includes the two most popular formats out of the box: HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming (DASH). These two implementations are written in pure Javascript and simple wrappers around hls.js and dash.js. The module will fallback to native browser support if needed (as in the case for iOS Safari).

The primary goal of this library is to allow <video> elements to accept a source in the required format (ex: .m3u8 files) and react to changes when src is changed in an angular component.

How this would look in practice:

HLS:

<video floMse src="https://www.streambox.fr/playlists/x36xhzz/x36xhzz.m3u8"></video>

DASH

<video floMse src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd"></video>

MSE Installation (required for any of the supported extensions)

Save the library as an application dependency

npm i @flosportsinc/ng-media-source-extensions

Import the module into your angular application

import { NgModule } from '@angular/core'
import { FloMseModule } from '@flosportsinc/ng-media-source-extensions'

@NgModule({
  imports: [FloMseModule]
})
export class AppModule { }

HLS Installation

Save the library as an application dependency

npm i @types/hls.js hls.js

Import the module into your angular application

import { NgModule } from '@angular/core'
import { FloHlsModule, FloMseModule } from '@flosportsinc/ng-media-source-extensions'

@NgModule({
  imports: [
    FloMseModule,
    FloHlsModule, // without config overrides
    FloHLsModule.config({
      floConfig: {
        selfHeal: true // attempts to fix errors automatically
      },
      hlsConfig: {
        capLevelToPlayerSize: true, // this module defaults to responsive renditions
        startLevel: -1 // this module defaults to auto start leveling
      } // See: https://github.com/video-dev/hls.js/blob/master/docs/API.md#fine-tuning
    })
  ]
})
export class AppModule { } // If you are using Angular Universal, this MUST be in your AppBrowserModule

Now you are free to .m3u8 HLS files in all modern browsers.

<video floMse src="https://www.streambox.fr/playlists/x36xhzz/x36xhzz.m3u8"></video>

DASH Installation

Save the library as an application dependency

npm i dashjs

Import the module into your angular application

import { NgModule } from '@angular/core'
import { FloDashModule, FloMseModule } from '@flosportsinc/ng-media-source-extensions'

@NgModule({
  imports: [
    FloMseModule,
    FloDashModule
  ]
})
export class AppModule { } // If you are using Angular Universal, this MUST be in your AppBrowserModule

Now you are free to .mpd files in all modern browsers.

<video floMse src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd"></video>

Usage

The floMse directive emits 3 keys events srcChange, mseClient, mseClientMessage

  • (srcChange): whenever a video elements src property changes, this event fires.
  • (mseClient): when the video's MSE client (for example hls.js) loads, this event fires and send the reference to the mse client.
  • (mseClientMessage): the clients usually have a way to log messages, this event forwards those message through the directive.
<!-- You are able to double bind to "src" and "floMseClient" attributes or simply use (srcChange) and (floMseClientChange) -->
<video floMse 
  [(src)]="src"
  (srcChange)="sourceChanged($event)" 
  [(floMseClient)]="mseClient"
  (floMseClientChange)="mseClientChange($event)" 
  (floMseClientMessageChange)="message($event)" 
  src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd">
</video>
import { NgModule } from '@angular/core'

@NgModule({
  imports: [
    FloMseModule,
    FloDashModule
  ]
})
export class MyComponent {

  sourceChanged(evt: string) {
    // do something with the url
  }

  mseClientChange(evt: MseClientContext<TMseClient>) {
    evt.contextKey.tapSome(console.log) // if exists, will print "hls"
    evt.mseClient.tapSome(client => {
      client.performLibraryMagic // this would be the hls.js instance with associated video already setup.
    })
  }

  message(evt: any) {
    // do something with the messages
  }
}
