注意：videojs升级后，不能用extend创建组件，需要按下方代码建一个组件

VideoPausedIcon.ts 组件

javascript 复制代码

    // 监听，暂停播放，显示播放按钮
    player.on("pause", () => {
      this.visible = true;
      const el = this.el();
      el.className = "vjs-define-paused";
    });
    // 监听，开始播放，隐藏播放按钮，通过videojs自带的 vjs-hidden 类
    player.on("play", () => {
      this.visible = false;
      const el = this.el();
      el.className = "vjs-define-paused vjs-hidden";
    });
    this.on("touchstart", this.handleTouchStart);
    this.on("touchend", this.handleTouchEnd);
    // 如果需要在web端使用，必须，不兼容的话，web端点击按钮就不会暂停/播放
    this.on("click", (e: any) => this.handleClick(e, player));
  }

    let pauseIcon = videojs.dom.createEl("div", {
      className: "vjs-define-paused",

    });

    return pauseIcon;
  }

    // 此处必须，不然点击按钮不能播放/暂停
    e.stopPropagation();
  }
