ffmpegthumbs 4:15.12.3-0ubuntu1 uses the wrong path for plugin libraries

[Stéphane]

ffmpegthumbs 4:15.12.3-0ubuntu1 puts ffmpegthumbs.so under /usr/lib/x86_64-linux-gnu/plugins/ (see http://packages.ubuntu.com/xenial/amd64/ffmpegthumbs/filelist for the newest package file listing).
Dolphin looks for plugins under /usr/lib/x86_64-linux-gnu/qt5/plugins/ (see http://packages.ubuntu.com/xenial/amd64/dolphin/filelist for the newest package file listing).
Because of the discrepancy between the two pathes Dolphin is unable to invoke ffmpegthumbs.

This can be reproduced with the Kubuntu 16.04 LTS live image. After installing ffmpegthumbs and activating it under the Dolphin preferences no thumbnails are generated for videos.

There is a workaround until the package is fixed. This command will link all the files from /usr/lib/x86_64-linux-gnu/plugins/ to /usr/lib/x86_64-linux-gnu/qt5/plugins/:

sudo ln -s /usr/lib/x86_64-linux-gnu/plugins/* /usr/lib/x86_64-linux-gnu/qt5/plugins/

The installation routine of the package should be fixed to unpack ffmpegthumbs.so under /usr/lib/x86_64-linux-gnu/qt5/plugins/.

I just noticed that the proposed fix fails when the package kio-extras is not installed. Currently the package ffmpegthumbs does not depend on kio-extras. Could that be changed too? Thanks!

would just be nice, if such a simple fix could scratch into 16.04.1

Not a lot of time left....
