A quick Google search doesn't bring up anything obvious that would be able to parse QTFF metadata with a GLib-style interface. The exiftool implementation of HEIC metadata reading is here:īased on that, it seems like ISO ISO 14496-12:2015 parsing would be needed. is used as abstraction in EoG to read metadata, and it has implementations for JPG and PNG metadata only (with mostly custom implementations, using libexif, lcms and exempi for some of the lower devel details).Įxiftool has support for reading HEIC image data, but a quick Google search brings up this eog-list post from 2005 which suggests that implementing an "eog-metadata-reader-exiftool" that runs exiftool (which does have a -json option for outputting machine-readable metadata as JSON for tool consumption) as subprocess is probably not desirable - is this still true?Īnyway, exiftool -verbose somefile.heic can be used to see how exiftool understands and interprets the container format, it seems to contain both Exif and XMP information. Looking at the sources, it looks like eog-metadata-reader. However, metadata (date/time of photo taken, GPS position, etc.) is not displayed at all. After installing, type “exiftool” in a Terminal window to run exiftool and read the application documentation.With #36 (closed) fixed, and (on Ubuntu) the heif-gdk-pixbuf package, viewing HEIF/HEIC files with EoG works fine.
