实现这个函数，使用mov demuxer和mp4box，如果文件过多注意拆分一些逻辑作为函数放在单独的mp4utils文件里面

I'll help you implement the `convertMOVtoMP4` function using mov-demuxer and mp4box. I'll also create a separate utilities file for better code organization.

First, let me check the `package.json` to see if mp4box is already available: Let me check if mp4box-related packages are included: Great! I can see that both `mp4-muxer` and `mp4box` are already installed. Now let me create a separate utilities file for MP4 operations and implement the conversion function.
