描述
Expected Behavior
Metadata-Extractor will also check for/extract externally specified metadata (EXIF, XMP, and MPEG-7)
Current Behavior
Metadata-Extractor only extracts metadata specified by HEIF itself
Detailed Description
There is potential for externally specified metadata: EXIF, XMP, and MPEG-7. More information on how to get at this data is provided in Annex A of ISO/IEC 23008-12:2017.
Issue originally branched from #362 : 4. cannot get the Exif info from the mdat box, I think this feature has not been implemented yet. :)
