j d „ « Zy) ÚAbstractMovieWriteraœ
|
|||
|
|
Abstract base class for writing movies, providing a way to grab frames by
|
|||
|
|
calling `~AbstractMovieWriter.grab_frame`.
|
|||
|
|
|
|||
|
|
`setup` is called to start the process and `finish` is called afterwards.
|
|||
|
|
`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()`.

|
|
|

All keyword arguments in *savefig_kwargs* are passed on to the
|
|||
|
|
`~.Figure.savefig` call that saves the figure. However, several
|
|||
|
|
keyword arguments that are supported by `~.Figure.savefig` may not be
|
|||
|
|
passed as they are controlled by the MovieWriter:
|
|||
|
|
|
|||
|
|
- *dpi*, *bbox_inches*: These may not be passed because each frame of the
|
|||
|
|
animation much be exactly the same size in pixels.
|
|||
|
|
- *format*: This is controlled by the MovieWriter.

|
|
Base class for writing movies.
|
|||
|
|
|
|||
|
|
This is a base class for MovieWriter subclasses that write a movie frame
|
|||
|
|
data to a pipe. You cannot instantiate this class directly.
|
|||
|
|
See examples for how to use its subclasses.
|
|||
|
|
|
|||
|
|
Attributes
|
|||
|
|
----------
|
|||
|
|
frame_format : str
|
|||
|
|
The format used in writing frame data, defaults to 'rgba'.
|
|||
|
|
fig : `~matplotlib.figure.Figure`
|
|||
|
|
The figure to capture data from.
|
|||
|
|
This must be provided by the subclasses.

Parameters
|
|||
|
|
----------
|
|||
|
|
fps : int, default: 5
|
|||
|
|
Movie frame rate (per second).
|
|||
|
|
codec : str or None, default: :rc:`animation.codec`
|
|||
|
|
The codec to use.
|
|||
|
|
bitrate : int, default: :rc:`animation.bitrate`
|
|||
|
|
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_args : list of str or None, optional
|
|||
|
|
Extra command-line arguments passed to the underlying movie encoder. These
|
|||
|
|
arguments are passed last to the encoder, just before the filename. The
|
|||
|
|
default, None, means to use :rc:`animation.[name-of-encoder]_args` for the
|
|||
|
|
builtin writers.
|
|||
|
|
metadata : dict[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.

Parameters
|
|||
|
|
----------
|
|||
|
|
fig : `~matplotlib.figure.Figure`
|
|||
|
|
The figure to grab the rendered frames from.
|
|||
|
|
outfile : str
|
|||
|
|
The filename of the resulting movie file.
|
|||
|
|
dpi : float, default: ``fig.dpi``
|
|||
|
|
The dpi of the output file. This, with the figure size,
|
|||
|
|
controls the size in pixels of the resulting movie file.
|
|||
|
|
frame_prefix : str, optional
|
|||
|
|
The filename prefix to use for temporary files. If *None* (the
|
|||
|
|
default), files are written to a temporary directory which is
|
|||
|

|
Pipe-based ffmpeg writer.
|
|||
|
|
|
|||
|
|
Frames are streamed directly to ffmpeg via a pipe and written in a single pass.
|
|||
|
|
|
|||
|
|
This effectively works as a slideshow input to ffmpeg with the fps passed as
|
|||
|
|
``-framerate``, so see also `their notes on frame rates`_ for further details.

|
|||
|
|
A base class for Animations.
|
|||
|
|
|
|||
|
|
This class is not usable as is, and should be subclassed to provide needed
|
|||
|
|
behavior.
|
|||
|
|
|
|||
|
|
.. note::
|
|||
|
|
|
|||
|
|
You must store the created Animation in a variable that lives as long
|
|||
|
|
as the animation should run. Otherwise, the Animation object will be
|
|||
|
|
garbage-collected and the animation stops.
|
|||
|
|
|
|||
|
|
Parameters
|
|||
|
|
----------
|
|||
|
|
fig : `~matplotlib.figure.Figure`
|
|||
|
|
The figure object used to get needed events, such as draw or resize.
|
|||
|
|
|
|||
|
|
event_source : object, optional
|
|||
|
|
A class that can run a callback when desired events
|
|||
|
|
are generated, as well as be stopped and started.
|
|||
|
|
|
|||
|
|
Examples include timers (see `TimedAnimation`) and file
|
|||
|
|
system notifications.
|
|||
|
|
|
|||
|
|
blit : bool, default: False
|
|||
|
|
Whether blitting is used to optimize drawing. If the backend does not
|
|||
|
|
support blitting, then this parameter has no effect.

|||

|
|||
|
|
Parameters
|
|||
|
|
----------
|
|||
|
|
filename : str
|
|||
|
|
The output filename, e.g., :file:`mymovie.mp4`.
|
|||
|
|
|
|||
|
|
writer : `AbstractMovieWriter` subclass or str, default: :rc:`animation.writer`
|
|||
|
|
The writer used to grab the frames and create the movie file.
|
|||
|
|
This can be an instance of an `AbstractMovieWriter` subclass or a
|
|||
|
|
string. The builtin writers are
|
|||
|
|
|
|||
|
|
================== ==============================
|
|||
|
|
str class
|
|||
|
|
================== ==============================
|
|||
|
|
'ffmpeg' `.FFMpegWriter`
|
|||
|
|
'ffmpeg_file' `.FFMpegFileWriter`
|
|||
|
|
'imagemagick' `.ImageMagickWriter`
|
|||
|
|
'imagemagick_file' `.ImageMagickFileWriter`
|
|||
|
|
'pillow' `.PillowWriter`
|
|||
|
|
'html' `.HTMLWriter`
|
|||
|
|
================== ==============================
|
|||
|
|
|
|||
|
|
fps : int, optional
|
|||
|
|
Movie frame rate (per second). If not set, the frame rate from the
|
|||
|
|
animation's frame interval.
|
|||
|
|
|
|||
|
|
dpi : float, default: :rc:`savefig.dpi`
|
|||
|
|
Controls the dots per inch for the movie frames. Together with
|
|||
|
|
the figure's size in inches, this controls the size of the movie.
|
|||
|
|
|
|||
|
|
codec : str, default: :rc:`animation.codec`.
|
|||
|
|
The video codec to use. Not all codecs are supported by a given
|
|||
|
|
`MovieWriter`.
|
|||
|
|
|
|||
|
|
bitrate : int, default: :rc:`animation.bitrate`
|
|||
|
|
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_args : list of str or None, optional
|
|||
|
|
Extra command-line arguments passed to the underlying movie encoder. These
|
|||
|
|
arguments are passed last to the encoder, just before the output filename.
|
|||
|
|
The default, None, means to use :rc:`animation.[name-of-encoder]_args` for
|
|||
|
|
the builtin writers.
|
|||
|
|
|
|||
|
|
metadata : dict[str, str], default: {}
|
|||
|
|
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.
|
|||
|
|
|
|||
|
|
extra_anim : list, default: []
|
|||
|
|
Additional `Animation` objects that should be included
|
|||
|
|
in the saved movie file. These need to be from the same
|
|||
|
|
`.Figure` instance. Also, animation frames will
|
|||
|
|
just be simply combined, so there should be a 1:1 correspondence
|
|||
|
|
between the frames from the different animations.
|
|||
|
|
|
|||
|
|
savefig_kwargs : dict, default: {}
|
|||
|
|
Keyword arguments passed to each `~.Figure.savefig` call used to
|
|||
|
|
save the individual frames.
|
|||
|
|
|
|||
|
|
progress_callback : function, optional
|
|||
|
|
A callback function that will be called for every frame to notify
|
|||
|
|
the saving progress. It must have the signature ::
|
|||
|
|
|
|||
|
|
def func(current_frame: int, total_frames: int) -> Any
|
|||
|
|
|
|||
|
|
where *current_frame* is the current frame number and *total_frames* is the
|
|||
|
|
total number of frames to be saved. *total_frames* is set to None, if the
|
|||
|
|
total number of frames cannot be determined. Return values may exist but are
|
|||
|
|
ignored.
|
|||
|
|
|
|||
|
|
Example code to write the progress to stdout::
|
|||
|
|
|
|||
|
|
progress_callback = lambda i, n: print(f'Saving frame {i}/{n}')
|
|||
|
|
|
|||
|
|
Notes
|
|||
|
|
-----
|
|||
|
|
*fps*, *codec*, *bitrate*, *extra_args* and *metadata* are used to
|
|||
|
|
construct a `.MovieWriter` instance and can only be passed if
|
|||
|
|
*writer* is a string. If they are passed as non-*None* and *writer*
|
|||
|
|
is a `.MovieWriter`, a `RuntimeError` will be raised.

Convert the animation to an HTML5 ``<video>`` tag.
|
|||
|
|
|
|||
|
|
This saves the animation as an h264 video, encoded in base64
|
|||
|
|
directly into the HTML5 video tag. This respects :rc:`animation.writer`
|
|||
|
|
and :rc:`animation.bitrate`. This also makes use of the
|
