It doesn't seem to work for images (as tested from the minimal example I posted above...)
But, from searching on this forum (or on Google), the answer for pictures is given here:
https://forum.qt.io/topic/83259/get-metadata-date-taken-location-from-photo-jpeg/2

Have a look at:

hi .
i found a library called mediainfo .here is the github
it has a example made by qt.
but i don't understand how to build it or use it as a lib.
can you help?and i tried this but not getting the duration.
m_player->metaData(QMediaMetaData::Duration).toString();just giving me this "QVariant(Invalid)"

@saber, that's a question you should ask to the
mediainfoauthors. At least you should explain exactly what is happening to you. -

As @SGaist suggested, I'm affraid that you will have to ask the authors of that library, as I haven't tried that one yet :-(.

Since
QMediaMetaData::Durationis aqint64as per http://doc.qt.io/qt-5/qmediametadata.html, maybe try as follows:QString::number(m_player->metaData(QMediaMetaData::Duration)) -

Thanks, mediainfo builds fine in my linux system.
i want it as a lib(exclude all the gui and extra pieces) so it will be easer to include it in my project.
i wanted to make a function that will take the file path >> send it to that lib >>lib will give the all the mediainfo.
but i have no idea or programming skills to do that .so if you want the same ,please modify the mideainfo to a library.

MediaInfoLibIS the lib. I thought this would have been clear enough...
MediaInfois just an application using it. Study that example to learn how to use it. -

MediaInfobuilds correctly on your system, so you have access to all the info you need, since it builds perfectly in Qt Creator. Don't expect everything to be done for you...
Good luck!
