I'm trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.
I tried a couple of versions, all with the same result, e.g.:
ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0 -acodec copy output.mp4
This should work, it already gives the correct preview of metadata:

I also tried to add the one tag I'm interested in by hand with
-metadata:g location=+48.2683+007.7205+172.710/
with no change in the result.
Output as .mov doesn't change anything, neither.
Is there any trick to add non-standard metadata? How do I get the location back in there?
Thanks in advance to anyone who can give some insight on this.
