Strigi is its own fileindexing system. Nepomuk only used its metadata 
extractors to get the information. But strigi does not support/use Nepomuk's 
storage. So if you want to use strigi directly, you would have to start the 
strigi daemon and let strigi index your files.

There are of course other programs than dolphin that use Nepomuk and its data, 
you can even make your own custom queries by using the nepomuksearch:/ kio-
slave f.e.: http://userbase.kde.org/Nepomuk/kioslaves/search
Also, Nepomuk is not only used for file indexing/filesearching, it is also 
used for dolphin's file information panel, the information popup when hovering 
over a file, and the "Properties" dialog. So you would need strigi from 
Packman to see all the information for multimedia files there.

OTOH, starting with KDE 4.10 Nepomuk does NOT use strigi any more, it got its 
own indexers/metadata extractors written from scratch. So it's actually moot 
now whether you install strigi from Packman or from openSUSE. (Although AFAIK 
the "Properties" dialog still uses the old Nepomuk widget using strigi on 4.10 
and 4.11)
You would need nepomuk-core-ffmpeg now for full multimedia support. A package 
for this does exist on Packman, but that's extremely outdated (4.10.0), and 
therefore useless.
I created my own on OBS, which I plan to submit to the KDE repositories, but I 
don't know yet whether the fake libffmpeg-devel would be accepted there (it is 
in KDE:Extra already).

Hope that clears up some things... ;)
