HTML部分
<video id="video" style="width: 0px;height: 0px;" autoplay="autoplay" loop="loop" crossorigin="crossorigin" controls="controls" muted="muted">
<source src="ModelData/video/luancheng.mp4" type="video/mp4">
</video>
JS部分
var videoElement, projectionImage, videoHandler;
projectionImage = new Cesium.ProjectionImage(scene);
videoHandler = new Cesium.DrawHandler(viewer, Cesium.DrawMode.Point);//视频投放
videoElement = document.getElementById('video');
videoElement.children[0].src = data._attr.spdz;
videoElement.currentSrc = data._attr.spdz;
videoElement.load();
目前是 projectionImage.setImage({video: videoElement});
只要videoElement有上面JS的修改视频地址src的部分，setImage时候必报错 请问是什么问题？？？
