在Chrome上使用Shaka播放器播放HLS m3u8

Question

我遵循shaka的基本用法来处理DASH视频，但在尝试加载M3U8时抛出了一个错误代码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依赖项包括

 "shaka-player": "^3.0.1",

并且还安装了(可能不需要)

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

它可以在Safari上运行，但在Chrome上就不行。我想我遗漏了一些与mux.js相关的东西。

有什么提示吗？非常感谢！

Answer 1

事实证明，它只需添加以下内容即可工作

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

到Angular的index.html。导入不起作用。不需要进行额外的配置。Shaka会检测到它并使用它。

而是因为我想要keep the dependency inside the app。我将js复制到assets文件夹(as referencing from node modules does not work。

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

遗憾的是，从angular.json脚本引用也不起作用。

尝试对import执行此操作以保留依赖关系：

import muxjs from 'mux.js';

interface MyWindow extends Window {
    muxjs: string;
}

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