Video metadata are supported if you use Exiv2 shared library version 0.24 :

http://www.exiv2.org/changelog.html

>> 0000813: Video metadata support (Abhinav Badola for GSoC 2012)

libkexiv2 and digiKam must be recompiled with this release of Exiv2, else nothing happen with video file about metadata.

Comment 2 caulier.gilles 2014-08-20 13:51:09 UTC 
Did you try to reproduce the problem with last digiKam 4.3.0 and Exiv2 0.24 ?

Can you share a MP4 file including geolocation info ?

Problem is reproducible with Exiv2 0.14 and digiKam 4.3.0.

Please report this problem to Exiv2 bugzilla, with file attached for future investigations.

Comment 7 caulier.gilles 2018-03-03 08:41:49 UTC 
With 6.0.0, we have now a FFMpeg low level metadata parser based on libav C API
for video files database registration.

The Exiv2 video support is not used anymore as this code is buggous and nobody
sound motivated in Exiv2 to finalize the code.

The original post for this file must be fixed now and video metadata support
with ffmpeg must be enough to populate database entries.
