Hi, I have few questions about the QuickTimeMov.swift & JPEG.swift main purpose.

  1. Is that these two class main purpose is add the assetIdentifier?
  2. Why the assetIdentifier so important? Is that main for Photos to recognize them as a live photo?
  3. What is the purpose of StillImageTime? Is that for Photos to judge where the still image position in the video file?

I find some demos on GitHub using your QuickTimeMov.swift, but the file has mzp & LoveLiver headers. So I come here.
Thanks.
