HarmonyOS 鸿蒙Next 播放视频，多个XComponent公用一个AVPlayer

多个XComponent如何公用一个AVPlayer？ 更换XComponent 后 新的surfaceId无法和已有AVPlayer实例绑定。 现在我的做法是用一个实例：AVPlayer

A页面代码片段:

XComponent({
  id: 'xComponentId',
  type: XComponentType.SURFACE,
  controller: this.xComponentController
})
  .width('100%')
  .height('100%')
  .visibility(Visibility.Hidden)
  .onLoad(() => {
    AdLog.info('AdSplashClickEyeView', 'buildVideoImpl onLoad')
    let surfaceId = this.xComponentController.getXComponentSurfaceId()
    AdMediaPlayer.instance.bindSurfaceId(surfaceId)
    AdMediaPlayer.instance.prepare(adBeanBase.videoUrl)
  })

B页面代码片段：

XComponent({
  id: 'xComponentId',
  type: XComponentType.SURFACE,
  controller: this.xComponentController
})
  .width('100%')
  .height('100%')
    // .visibility(Visibility.Hidden)
  .onLoad(() => {
    AdLog.info('AdSplashClickEyePage', 'buildVideoImpl onLoad')
    let surfaceId = this.xComponentController.getXComponentSurfaceId()
    AdMediaPlayer.instance.bindSurfaceId(surfaceId)
    AdMediaPlayer.instance.play(adBeanBase.videoUrl)
  })

AVPlayer代码片段：

async bindSurfaceId(surfaceId: string) {
  hilog.error(0x0000, TAG, `bindSurfaceId surfaceId=${surfaceId}`)
  this.surfaceId = surfaceId
  if (this.player) {
    this.player.surfaceId = this.surfaceId;
  }
}

// 状态机变化回调函数

player.on('stateChange', async (state: string, reason: media.StateChangeReason) => {
  switch (state) {
    case 'idle': // 成功调用reset接口后触发该状态机上报
      hilog.info(0x0000, TAG, 'callback idle state')
      break;
    case 'initialized': // avplayer 设置播放源后触发该状态上报
      hilog.info(0x0000, TAG, 'callback initialized state')
      player.surfaceId = this.surfaceId; // 设置显示画面，当播放的资源为纯音频时无需设置
      player.prepare();
      break;
  }
})
