I have draft changes here: https://github.com/ajmas/exif/tree/json-output

Not ready to be merged, for the following reasons:

  • Not sure the best place to be putting the following functions:
    exif_data_foreach_content_ext
    exif_content_foreach_entry_ext

  • While the code does generate a syntactically correct JSON , it doesn't eliminate duplicate entries, though wondering whether it is acceptable, since this matches the xml behaviour.

I am not a really a C developer, so it could be much better.
