matplotlib.animation.AbstractMovieWriter

class matplotlib.animation.AbstractMovieWriter

Abstract base class for writing movies. Fundamentally, what a MovieWriter does is provide is a way to grab frames by calling grab_frame().

setup() is called to start the process and finish() is called afterwards.

This class is set up to provide for writing movie frame data to a pipe. saving() is provided as a context manager to facilitate this process as:

with moviewriter.saving(fig, outfile='myfile.mp4', dpi=100):
    # Iterate over frames
    moviewriter.grab_frame(**savefig_kwargs)

The use of the context manager ensures that setup() and finish() are performed as necessary.

An instance of a concrete subclass of this class can be given as the writer argument of Animation.save().
