Title: Trying to inject XMP-GSpherical TimeStamp to a MP4 LG-360 spherical video
Post by: andresdevandelvira on October 08, 2017, 06:23:07 PM
Hello, this is my first time in this Forum, I'm a very inexperienced user of Exiftool command line...  :-[, usually using Exiftool Gui.

My OS: Windows 10 64 Bits
ExifTool version: 10.6.3.0

I'm trying to inject Xmp:TimeStamp metadata to a Spherical LG-360 Cam mp4 video.

The original Video has right date (Tag Xmp:TimeStamp), but the stitched video, injected with "Spherical Metadata Tool" has lost several metadata, including TimeStamp one.

If I export right original video metadata to xmp (using Exiftool GUI), the obtained file doesn't contains part of the metadata, including Xmp TimeStamp.

I'm trying to "reinject" these data with a command line,

exiftool.exe "-XMP-GSpherical:TimeStamp=2005:08:30 20:00:00" C:\20170829.mp4

but I always get the error:

Warning: Invalid date/time (use YYYY:mm:dd HH:MM:SS[.ss][+/-HH:MM|Z]) for XMP-GSpherical:TimeStamp
Nothing to do.
<-END-


This error appears also if I try to inject these metadata using Exiftool GUI.

Thanks,

This is a bug in ExifTool, but I don't think that fixing this bug will help because I believe that Google (for whatever reason) doesn't write the GSpherical XMP to the location specified by the XMP standard.  ExifTool will write this to the standard XMP location.

I will fix this bug (the tag's Writable format should be "integer" instead of "date"), but I don't want to get your hopes up too much.

Ok, I understand.  ;)

Thanks for your impressive work.

Just a note:  ExifTool 11.54 or later (July 2019) writes GSpherical tags to the GSphericalXML of the video track.
