matplotlib.animation.FFMpegFileWriter

class matplotlib.animation.FFMpegFileWriter(*args, **kwargs)

Bases: matplotlib.animation.FFMpegBase, matplotlib.animation.FileMovieWriter

File-based ffmpeg writer.

Frames are written to temporary files on disk and then stitched together at the end.

args_key = u'animation.ffmpeg_args'

classmethod bin_path()

Returns the binary path to the commandline tool used by a specific subclass. This is a class method so that the tool can be looked for before making a particular MovieWriter subclass available.

cleanup()

exec_key = u'animation.ffmpeg_path'

finish()

frame_format

Format (png, jpeg, etc.) to use for saving the frames, which can be decided by the individual subclasses.

frame_size

A tuple (width, height) in pixels of a movie frame.

grab_frame(**savefig_kwargs)

Grab the image information from the figure and save as a movie frame. All keyword arguments in savefig_kwargs are passed on to the savefig command that saves the figure.

classmethod isAvailable()

Check to see if a MovieWriter subclass is actually available by running the commandline tool.

output_args

saving(**kwds)

Context manager to facilitate writing the movie file.

*args, **kw are any parameters that should be passed to setup.

setup(fig, outfile, dpi=None, frame_prefix=u'_tmp', clear_temp=True)

Perform setup for writing the movie file.

Parameters:

fig : matplotlib.figure.Figure

The figure to grab the rendered frames from.

outfile : str

The filename of the resulting movie file.

dpi : number, optional

The dpi of the output file. This, with the figure size, controls the size in pixels of the resulting movie file. Default is fig.dpi.

frame_prefix : str, optional

The filename prefix to use for temporary files. Defaults to '_tmp'.

clear_temp : bool, optional

If the temporary files should be deleted after stitching the final result. Setting this to False can be useful for debugging. Defaults to True.
