有没有人把视频记录和角7集成在一起？

Question

我试图用视频录制视频，我的应用程序是角7，我跟踪了他们的wiki。下面是https://github.com/collab-project/videojs-record/wiki/Angular下面的链接，但这对我不起作用。

这是我所得到的错误

ERROR in ./node_modules/videojs-record/dist/videojs.record.js
Module not found: Error: Can't resolve 'RecordRTC' in '/path/to/project/root/node_modules/videojs-record/dist'
ERROR in ./node_modules/videojs-record/dist/videojs.record.js
Module not found: Error: Can't resolve 'videojs' in '/path/to/project/root/node_modules/videojs-record/dist'

这是我的代码和我的视频is在视频记录器.组件中的配置

import { Component, OnInit, OnDestroy, ElementRef, Input } from '@angular/core';
import videojs from 'video.js';
import * as adapter from 'webrtc-adapter/out/adapter_no_global.js';
import * as RecordRTC from 'recordrtc';

// register videojs-record plugin with this import
import * as Record from 'videojs-record/dist/videojs.record.js';

@Component({
  selector: 'app-video-recorder',
  templateUrl: './video-recorder.component.html',
  styleUrls: ['./video-recorder.component.scss']
})
export class VideoRecorderComponent implements OnInit, OnDestroy {
  // reference to the element itself: used to access events and methods
  private _elementRef: ElementRef;

  // index to create unique ID for component
  @Input() idx: string;

  private config: any;
  private player: any; 
  private plugin: any;

  // constructor initializes our declared vars
  constructor(elementRef: ElementRef) {
    this.player = false;

    // save reference to plugin (so it initializes)
    this.plugin = Record;

    // video.js configuration
    this.config = {
      controls: true,
      autoplay: false,
      fluid: false,
      loop: false,
      width: 320,
      height: 240,
      controlBar: {
        volumePanel: false
      },
      plugins: {
        // configure videojs-record plugin
        record: {
          audio: false,
          video: true,
          debug: true
        }
      }
    };
  }

  ngOnInit() {}

  // use ngAfterViewInit to make sure we initialize the videojs element
  // after the component template itself has been rendered
  ngAfterViewInit() {
    // ID with which to access the template's video element
    let el = 'video_' + this.idx;

    // setup the player via the unique element ID
    this.player = videojs(document.getElementById(el), this.config, () => {
      console.log('player ready! id:', el);

      // print version information at startup
      var msg = 'Using video.js ' + videojs.VERSION +
        ' with videojs-record ' + videojs.getPluginVersion('record') +
        ' and recordrtc ' + RecordRTC.version;
      videojs.log(msg);
    });

    // device is ready
    this.player.on('deviceReady', () => {
      console.log('device is ready!');
    });

    // user clicked the record button and started recording
    this.player.on('startRecord', () => {
      console.log('started recording!');
    });

    // user completed recording and stream is available
    this.player.on('finishRecord', () => {
      // recordedData is a blob object containing the recorded data that
      // can be downloaded by the user, stored on server etc.
      console.log('finished recording: ', this.player.recordedData);
    });

    // error handling
    this.player.on('error', (element, error) => {
      console.warn(error);
    });

    this.player.on('deviceError', () => {
      console.error('device error:', this.player.deviceErrorCode);
    });
  }

  // use ngOnDestroy to detach event handlers and remove the player
  ngOnDestroy() {
    if (this.player) {
      this.player.dispose();
      this.player = false;
    }
  }

}

这是我的视频录音机。

我对角质很陌生。因此，在这方面的任何帮助都将不胜感激。提前谢谢。

Answer 1

不用担心，伙计们，我自己修好了。在做了一些研究之后，我了解到，由于我使用角cli来服务和构建，所以我使用了ngx- (因为ng eject在角7中被废弃，并将从角8中删除)来使用角cli执行webpack配置。这个webpack的配置之前就不见了。这可能会帮助到某个人，这就是为什么要分享的原因。谢谢。

Answer 2

你不能那样用。如果您使用角cli服务或构建，那么您必须创建一个部分webpack配置文件，并服务或构建它通过角cli。你应该跟随下面的事情。

请访问下面的链接和安装软件包，并按照指示配置您的人员。

https://www.npmjs.com/package/ngx-build-plus

你的webpack.partial.js应该看起来像

const webpack = require('webpack');

module.exports = {
    resolve: {
        alias: {
            // place your config
        }
    },
    plugins: [
        // place your config
    ],

}

而scripts在package.json文件中应该看起来像

"scripts": {
    "ng": "ng",
    "start": "ng serve --extra-webpack-config webpack.partial.js",
    "build": "ng build --extra-webpack-config webpack.partial.js",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "build:prod": "ng build --prod --extra-webpack-config webpack.partial.js",
    "build:stage": "ng build --prod -c staging --extra-webpack-config webpack.partial.js",
    "build:dev": "ng build -c development --extra-webpack-config webpack.partial.js"
  },

然后，您可以使用npm start为您的应用程序提供服务，构建您可以使用基于环境的npm run build:dev财政报告(npm run build:dev)\。
