IPTC tags

Sorry for asking something so obvious – as I assume – but is it possible to get IPTC tags with libextractor?

 

Using exiv2 directly with the options “exiv2 -p -i  file.jpeg” shows me what I am looking for, the IPTC.Application2.Keywords tag used by various GUI tools. (I am not talking about exif.Keywords, that’s empty)

 

Once this is possible, I can use an import.js script in mediatomb to see all my images on the UPNP clients categorized, e.g. Spain, Vacation, Family, Rating=***** etc.

 

My current investigation seems to indicate the list of possibly returned keywords by extract or libextractor is fixed, not controlled by the exiv2 library??

 

Thanks,

 

Werner

Hi!

I'm not sure this is obvious.  LE doesn't do this right now, I suspect that
what it'll take is adding a line like:

result = addExiv2Tag(exifData,
                             "IPTC.Application2.Keywords",
                             EXTRACTOR_KEYWORDS,
                             result);

to exiv2extractor.cc.  If you could provide me with a file for testing, I'll be
happy to try to make this change.

Thanks!

Christian
