我正在做一个程序，该程序会自动下载Reddit的一些视频，并在使用OpenCV进行一些处理之后。问题是，当我尝试使用VideoCapture对象加载视频时，未创建该对象，并且出现以下错误：
[mov,mp4,m4a,3gp,3g2,mj2 @ 00000217e21f2800] moov atom not found
warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:901)

(node:16256) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
该视频似乎未损坏，因为我可以使用VLC正常播放该视频。
这是我用来加载视频的打字稿代码：
const video = new cv.VideoCapture(videoRef.localUrl);
如何摆脱这个错误？
OBS：：我正在将opencv4nodejs用于带有打字稿的节点。
