The ffmpegthumbs has been ported to the Qt5/KF5 - KDE review: https://git.reviewboard.kde.org/r/118545/ .
The problem seems to be that the ffmpegthumbs master branch is still for the KDE4 and the KDE Applications 15.08 was releasing the ffmpegthumbs from the master.
For the Arch there is an option to use the KF5 version: https://bbs.archlinux.org/viewtopic.php?id=201484 .
