Thank you Palantir! There was indeed a workaround. This is what I did :

 sudo apt-get install git build-essential cmake extra-cmake-modules kio-dev pkg-config libavformat-dev libavcodec-dev libswscale-dev


git clone git://anongit.kde.org/ffmpegthumbs
cd ffmpegthumbs
git checkout origin/frameworks
mkdir -p builddir
cd builddir && cmake .. -DCMAKE_INSTALL_PREFIX=$(kf5-config --prefix) -DCMAKE_BUILD_TYPE=Release -DKDE_INSTALL_USE_QT_SYS_PATHS=ON
sudo make install

And when I restarted Dolphin I found this :

So it works :)
