MPlayerThumbs is a thumbnail generator for all KDE file managers (konqueror, dolphin, ...) It needs mplayer (of course) to generate thumbnails, and it contains no linking to any library, so in a x86_64 system you can freely use the 32bit mplayer binary with win32codecs by configuring the application launching the mplayerthumbsconfig helper application.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
