matplotlib.animation.FFMpegWriter

class matplotlib.animation.FFMpegWriter(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None) [source]

Pipe-based ffmpeg writer.

Frames are streamed directly to ffmpeg via a pipe and written in a single pass.

Parameters:

Parameters:	`fpsint, default: 5` Movie frame rate (per second). `codecstr or None, default: rcParams["animation.codec"] (default: 'h264')` The codec to use. `bitrateint, default: rcParams["animation.bitrate"] (default: -1)` The bitrate of the movie, in kilobits per second. Higher values means higher quality movies, but increase the file size. A value of -1 lets the underlying movie encoder select the bitrate. `extra_argslist of str or None, optional` Extra command-line arguments passed to the underlying movie encoder. The default, None, means to use `rcParams["animation.[name-of-encoder]_args"]` for the builtin writers. `metadataDict[str, str], default: {}` A dictionary of keys and values for metadata to include in the output file. Some keys that may be of use include: title, artist, genre, subject, copyright, srcform, comment.

fpsint, default: 5: Movie frame rate (per second).
codecstr or None, default: rcParams["animation.codec"] (default: 'h264'): The codec to use.
bitrateint, default: rcParams["animation.bitrate"] (default: -1): The bitrate of the movie, in kilobits per second. Higher values means higher quality movies, but increase the file size. A value of -1 lets the underlying movie encoder select the bitrate.
extra_argslist of str or None, optional: Extra command-line arguments passed to the underlying movie encoder. The default, None, means to use rcParams["animation.[name-of-encoder]_args"] for the builtin writers.
metadataDict[str, str], default: {}: A dictionary of keys and values for metadata to include in the output file. Some keys that may be of use include: title, artist, genre, subject, copyright, srcform, comment.
