Exiv2 gets video metadata support

Andreas Huggel et al. released a major new update of Exiv2, a low-level tool for reading and writing metadata such as Exif, XMP, and IPTC. The new version features reading metadata from video files.

The immediate benefit for end-users is being able to see basic info about video files in digiKam, a popular KDE's photo and video managment application.

Video metadata in digiKam

This new feature was added a year ago by Abhinav Badola, digiKam's Google Summer of Code student.

Additionally Exiv2 v0.25 got detection of Canon EOS 6D in metadata, as well as support for a whole bunch of lenses:

  • a complete Samsung NX lenses portfolio, Samsung D-Xenon 12-24mm;
  • a lot of Olympus lenses;
  • Sigma 50mm f/1.4 for Canon, 18-250mm for Pentax, 150-500mm f/5-6.3 APO DG OS HSM for Canon
  • Pentax DA 18-135mm F3.5-5.6;
  • Tamron SP 24-70mm F/2.8 Di VC USD;
  • Nikon AF-S Nikkor 28mm f/1.8G;
  • Canon EF 35mm f/2 IS USM, EF-S 55-250mm f/4-5.6 IS II.

There's also experimental CMake build system support. The new Exiv2 is not binary compatible, but most of API hasn't changed, hence if you compile software yourself, most likely you only need to rebuild it.

Exiv2 v0.25 should land to binary Linux distributions soon enough.

The next version is expected to feature the work done by Google Summer of Code 2013 students: writing metadata to video files (Mahesh Hegde) and remote files support (Nhu Dinh Tuan). Both students also worked on Exiv2 through digiKam as a mentoring organization.
