 onPlayVideo: function (e) {
      console.log(e)
      let id = e.currentTarget.dataset.id
  
      if (this.data.videoId != "" && this.data.videoId != id) {
        let ctx = wx.createVideoContext(this.data.videoId, this)
        ctx.stop()
        this.data.videoId = id
      } else {
        this.data.videoId = id
      }
    },

 在自定义组件中这种控制视频的方式没作用，在page 页面中是可以控制的

 目前遇到的问题是，富文本中出现多个video标签，没法控制同时只能播放一个
