Extractor of image and movie metadata with exiv2 backend.
See movie_publisher for more details.
The package code itself is BSD-licensed, but Exiv2 library which it includes and links to is GPL 2.0+ licensed.
You should thus consider this when using the extractor. Although movie_publisher will load this extractor dynamically at runtime, some still consider this linking, and thus the final program in memory will also be GPL-licensed.
You are free to use other EXIF-based plugins if you need something non-copyleft, like exiftool or exiv2.
