#4209(undetermined:new): GPS coordinates location and other iOS metadata in MOV are not copied to output MP4
#4209: GPS coordinates location and other iOS metadata in MOV are not copied to output MP4 -------------------------------------+------------------------------------- Reporter: elmimmo | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Certain metadata in MOV files recorded with iOS devices, such as GPS location, is lost when converting to MP4. **ffmpeg** does state in its log that the output file will contain such metadata, but such is not the case as identified with **ffprobe** and **exiftool**. Some of the metadata present in the input MOV that is missing in the output MP4, according to **ffprobe**: - make ("Apple") - encoder - location (GPS latitude/longitude/altitude coordinates) - model (the iPhone/iPad/iPod model) **exiftool** identifies some more: - camera identifier ("Back" or "Front") - Software Version (iOS version) This happens irrespective of input video/audio being transcoded or just repackaged.

I faced the same issue as the ticket's reporter: iOS doesn't show the location if media files were created by FFmpeg. After some analysis independently of TimvW1984, I've found where FFmpeg and iOS put their metadata tags: FFmpeg: `moov/udta/meta` iOS: `moov/meta` Furthermore, Apple's QuickTime specification [1] defines the correct location for the metadata tag: metadata atom is allowed for each location. The current FFmpeg implementation contradicts this specification and writes it inside the `udta` tag[2]. From that, I can conclude this is the cause of why location metadata is not recognized by Apple's software. [1]: https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/Met...
