Problem still reproducible with last stable digiKam 4.8.0 ?

*** This bug has been marked as a duplicate of bug 340373 ***
Comment 3 caulier.gilles 2018-02-28 12:38:10 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.
