How would I use this android app to copy 360 metadata/XMP tags from a 360 mp4 file which has working 360 metadata/XMP tags to a newly rendered video also mp4 which has incomplete 360 metadata/XMP tags. I know the new mp4 file 360 metadata is incomplete because it requires injection by Spatial Media Metadata Injector app on my Windows based PC to be viewed by VLC Media Player or to be edited by VeeR Editor on the android phone.
The goal here is to inject the missing 360 metadata/XMP tags on the android phone so other apps on the phone can edit the video. This would mean no transfer to PC for 360 metadata injection.
There isn't an official android port of exiftool, so no idea how it would work.
I believe there are multiple threads here on copying 360 metadata. If the forum search doesn't find them, then you can try with google and add site:exiftool.org to limit the search to these forums.
