在Chrome上使用Shaka Player播放HLS m3u8

我遵循可用于DASH视频的shaka的基本用法,但是在尝试加载M3U8时抛出错误代码4032。

import * as muxjs from 'mux.js';
import * as shaka from 'shaka-player';

export class AppComponent implements AfterViewInit {
  @ViewChild('videoPlayer') videoElementRef: ElementRef;
  videoElement: HTMLVideoElement;

  manifestUri = 'http://hlsliveamdgl7-lh.akamaihd.net/i/hlsdvrlive_1@583042/master.m3u8';


  ngAfterViewInit() {
    shaka.polyfill.installAll();
    this.videoElement = this.videoElementRef.nativeElement;
    this.initPlayer();
  }

  private initPlayer() {
    shaka.media.ManifestParser.registerParserByExtension("m3u8", shaka.hls.HlsParser);
    shaka.media.ManifestParser.registerParserByMime("Application/vnd.apple.mpegurl", shaka.hls.HlsParser);
    shaka.media.ManifestParser.registerParserByMime("application/x-mpegURL", shaka.hls.HlsParser);


    let player = new shaka.Player(this.videoElement);


    player.load(this.manifestUri).then(() => {
      // This runs if the asynchronous load is successful.
      console.log('The video has now been loaded!');
    }).catch(this.onError);  // onError is executed if the asynchronous load fails.
  }

模板是

  <video #videoPlayer
     id="video"
     width="640"
     poster="https://upload.wikimedia.org/wikipedia/commons/c/c4/PM5544_with_non-PAL_signals.png"
     controls> </video>

相关的Angular 9依赖项是

 "shaka-player": "^3.0.1",

并已安装(可能不必要)

"hls.js": "^0.13.2",
"mux.js": "^5.6.4",

在Safari上可以使用,而不能在Chrome上使用。我想我缺少与mux.js相关的内容。

有任何提示吗?非常感谢!

事实证明,只需添加此内容即可

<script src="https://github.com/videojs/mux.js/releases/latest/download/mux.js"></script>

至Angular的index.html。导入无效。无需执行其他配置。 Shaka会检测到并使用它。

但是我想keep the dependency inside the app。我将js复制到资产文件夹(as referencing from node modules does not work

<script defer src="assets/mux.min.js"></script>

从angular.json脚本中不幸地引用也不起作用。

试试这个导入以保持依赖:

import muxjs from 'mux.js';

interface MyWindow extends Window {
    muxjs: string;
}

(window as MyWindow & typeof globalThis).muxjs = muxjs;
