Exiv2 is a C++ library and a command line utility to manage image metadata.
It provides fast and easy read and write access to the Exif, IPTC, and XMP
metadata of images in various formats. Exiv2 is available as free software
and with a commercial license, and is used in many projects.
The exiftags utility parses a specified JPEG file or, by default, its standard
input, looking for a JPEG APP1 section containing Exif (Exchangeable Image
File) data. The properties contained in these data are then printed to the
standard output. Digital cameras typically add Exif data to the image files
they produce, containing information about the camera and digitized image.
The program supports a variety of cameras, and includes additional support for
a portion of the maker notes for Canon, Fuji, Nikon, and Olympus cameras.
This port provides OpenGL video elements for Gstreamer.
