Video playback: black window/screen with correct dimensions

There seems to be an issue with Video-Functions. If I add a video to the function editor, all metadata is detected correctly: file name, duration, resolution, video codec, audio codec and so on.
However, if I try to play/preview that video, there olny opens a black window (in windowed-mode, with correct dimensions) and nothing else happens.

This seems to be an issue with qlc+; if I try to play that video in a minimal qt application with QMediaPlayer and QVideoWidget everything works fine.

version: git master
