handleAssetsLoaded: function ({detail}) {
  this.setData({loaded: true});
},
handleTrackerSwitch: function ({detail}) {
  const active = detail.value;
  const video = this.scene.assets.getAsset('video-texture', 'hikari');
  active ? video.play() : video.stop();
}

使用console.log打印video是undefined

wxml：

 <xr-asset-load type="video-texture" asset-id="hikari" id="dalian" src="xxxxx" options="loop:true,autoPlay:true,abortAudio:false" />
