    src="http://wxsnsdy.tc.qq.com/105/20210/snsdyvideodownload?filekey=30280201010421301f0201690402534804102ca905ce620b1241b726bc41dcff44e00204012882540400&bizid=1023&hy=SH&fileparam=302c020101042530230204136ffd93020457e3c4ff02024ef202031e8d7f02030f42400204045a320a0201000400"
    danmu-list="{{danmuList}}"
    enable-danmu
    danmu-btn
    controls
  ></video>
  <view class="btn-area">
    <button bindtap="bindButtonTap">获取视频</button>
    <input bindblur="bindInputBlur" />
    <button bindtap="bindSendDanmu">发送弹幕</button>
  </view>
</view>

3. audio.js


function getRandomColor() {
  const rgb = []
  for (let i = 0; i < 3; ++i) {
    let color = Math.floor(Math.random() * 256).toString(16)
    color = color.length == 1 ? '0' + color : color
    rgb.push(color)
  }
  return '#' + rgb.join('')
}
Page({
  onReady(res) {
    this.videoContext = wx.createVideoContext('myVideo')
  },
  inputValue: '',
  data: {
    src: '',
    danmuList: [
      {
        text: '第 1s 出现的弹幕',
        color: '#ff0000',
        time: 1
      },
      {
        text: '第 3s 出现的弹幕',
        color: '#ff00ff',
        time: 3
      }]
  },
  bindInputBlur(e) {
    this.inputValue = e.detail.value
  },
  bindButtonTap() {
    const that = this
    wx.chooseVideo({
      sourceType: ['album', 'camera'],
      maxDuration: 60,
      camera: ['front', 'back'],
      success(res) {
        that.setData({
          src: res.tempFilePath
        })
      }
    })
  },
  bindSendDanmu() {
    this.videoContext.sendDanmu({
      text: this.inputValue,
      color: getRandomColor()
    })
  }
})

效果：
