vue项目中如何使用video.js实现视频播放与视频进度条打点

// 安装video.js插件
npm install video.js -S 

// 如果需要播放rtmp直播流，需安装一下插件
npm install videojs-flash -S

    // the component.

  // The `createEl` function of a component creates its DOM element.
  createEl: function() {
    return videojs.createEl('div', {

      // Prefixing classes of elements within a player with "vjs-" 
      // is a convention used in Video.js.
      className: 'vjs-title-bar'
    });
  },

  // This function could be called at any time to update the text 
  // contents of the component.

    // If no text was provided, default to "Title Unknown"

      text = 'Title Unknown';

    // Use Video.js utility DOM methods to manipulate the content
    // of the component's element.
    videojs.emptyEl(this.el());
    videojs.appendContent(this.el(), text);
  }
});

// Register the component with Video.js, so it can be used in players.
videojs.registerComponent('TitleBar', TitleBar);

// Create a player.
var player = videojs('my-player');

// Add the TitleBar as a child of the player and provide it some text 
// in its options.
player.addChild('TitleBar', {text: 'The Title of The Video!'});
