Hi,
actually using digikam 4.6 (original openSUSE 13.2) and updated 4.8 vom KDE:extra repository.

in both versions (4.8 works better) digikam cannot build my collection of photos after a complete new installation, i had to import my files (mostly jpg from different canons powershot G?? and DSLR, some videos) in the folders (i sort them in folders (one for each year and inside the folders per year there are the shooting-folders by date_location).
Even importing year by year it took several times until all my files are imported to the digikam database (sqlite), digikam crashed often (or stopped working with or without high cpu load), needed to remove some folders and add them later.
It didnt change if moving photo-folder into digikam album-folder was done while digikam was open or closed and if new photos were detected while starting digikam or via digikam-extras-Wartung (Service in english?)

is there a solution, planned changes in the future or how can the import of large collections be done - i think this is a "old" problem of digikam!?

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.
