【问题描述】：

我正在尝试在 Ionic 应用中创建 360 度视频播放器。我的代码如下。

html：

<ion-content>
    <video id="videojs-panorama-player" class="video-js vjs-default-skin" src=""  crossorigin="anonymous" controls ref="player">
        <source src="/assets/beach.mp4" type='video/mp4'>
    </video>
</ion-content>

打字稿：

import  Component  from '@angular/core';
import  NavController, Platform  from 'ionic-angular';
import videojs from 'video.js';
import panorama from 'videojs-panorama';

@Component(
  selector: 'page-home',
  templateUrl: 'home.html'
)

export class HomePage 

    private player: any;

    constructor(public navCtrl: NavController, private platform: Platform) 
        this.player = null;
        this.platform.ready().then(() => 
             this.init();
        );
    

    init() 
        this.player = videojs('videojs-panorama-player', ,  () => 
            window.addEventListener("resize", () => 
                var canvas = this.player.getChild('Canvas');
                if(canvas) canvas.handleResize();
            );
        );
        this.player.width(960), this.player.height(400);
        panorama(this.player, 
            clickToToggle: false,
            autoMobileOrientation: true,
            initFov: 100,
            VREnable: true,
            clickAndDrag: true,
            NoticeMessage: "touch to interact"
        );
        console.log("initialized");
    

当我ionic serve 时，此代码按预期工作，但是当我尝试构建到一个平台时，我遇到了一堆问题。 （ionic build ios 或 ionic build android）。

错误开始时记录：

我更新了我的 NPM、Node.js 和 sass。可能是什么问题呢？关于如何解决它的任何想法？非常感谢。

【参考方案1】：

我发现了问题所在。问题是 videos-panorama 不适用于某些 Typescript 绑定。我联系了开发人员，他更新了它，所以现在这段代码可以正常工作了。祝你好运！
