""" movieRead(filename, asNumpy=True)
Read the movie from GIF, SWF, AVI (or MPG), or a series of images (PNG,

Parameters
----------
filename : string
The name of the file that contains the movie. For a series of images,
the `*` wildcard can be used.
asNumpy : bool
If True, returns a list of numpy arrays. Otherwise return
a list if PIL images.
Notes
------
Reading AVI requires the "ffmpeg" application:
* Most linux users can install it using their package manager
* There is a windows installer on the visvis website
