matplotlib.animation.AVConvWriter
-
class matplotlib.animation.AVConvWriter(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None)
[source]
-
Pipe-based avconv writer.
Frames are streamed directly to avconv via a pipe and written in a single pass.
Parameters: |
-
fps : int -
Framerate for movie. -
codec : string or None, optional -
The codec to use. If None (the default) the animation.codec rcParam is used. -
bitrate : int or None, optional -
The bitrate for the saved movie file, which is one way to control the output file size and quality. The default value is None , which uses the animation.bitrate rcParam. A value of -1 implies that the bitrate should be determined automatically by the underlying utility. -
extra_args : list of strings or None, optional -
A list of extra string arguments to be passed to the underlying movie utility. The default is None , which passes the additional arguments in the animation.extra_args rcParam. -
metadata : Dict[str, str] or None -
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. |
