Parameters
----------
ec : instance of expyfun.ExperimentController
file_name : str
the video file path
pos : array-like
2-element array-like with X, Y elements.
units : str
Units to use for the position. See ``check_units`` for options.
scale : float | str
The scale factor. 1 is native size (pixel-to-pixel), 2 is twice as
large, etc. If `scale` is a string, it must be either ``'fill'``
(which ensures the entire ``ExperimentController`` window is
covered by the video, at the expense of some parts of the video
potentially being offscreen), or ``'fit'`` (which scales maximally
while ensuring none of the video is offscreen, and may result in
letterboxing or pillarboxing).
center : bool
If ``False``, the elements of ``pos`` specify the position of the lower
left corner of the video frame; otherwise they position the center of
the frame.
visible : bool
Whether to show the video when initialized. Can be toggled later using
``set_visible`` method.
Returns
-------
None

entertainment for the participant during a passive auditory task).
