Tony Thank you for sharing files! Yes, I received them.
I did some googling and it looks like this is regular JPG plus .mp4 file embedded into it. And probably some additional metadata too. So it does not look like like series of photos, but rather photo + video, just like in case of Apple live photos. However, Apple does not try to embed video into photo, it stores them as two separate files with similar name.
Adding support for live photos / motion photos will require serious UI rework, so I would like to be sure that there is significant demand for that feature. That means, it would be great if more users would show their support for this feature here.
