Review request for Okular.


Description
-------

In the old implementation the Phonon::VideoWidget::snapshot() method was used to create the first-frame (poster) images for a movie, however the Phonon API and the backends (gstreamer and vlc) provide no reliable way to take the snapshot of the first frame. For this reason this patch adds an additional option to use the libffmpegthumbnailer library to take the snapshot of the first frame.
It is faster than using the VideoWidget::snapshot() method and always returns the requested frame.
