Matplotlib-动画“没有可用的电影作家" [英] Matplotlib-Animation "No MovieWriters Available"

问题描述

在 Linux 下，我一直在检查 matplotlib 的动画类，它似乎有效，只是我无法初始化电影作家来写出电影.

Under Linux, I've been checking out matplotlib's animation class, and it seems to work except that I cant initialise the movie writer to write out the movie.

使用任一示例:

• http://matplotlib.org/examples/animation/moviewriter.html
• http://matplotlib.org/examples/animation/basic_example_writer.html

导致错误RuntimeError: No MovieWriters available！"

我使用的是 matplotlib 版本 1.3.x 并安装了(希望如此)所有的编解码器.

Im using matplotlib version 1.3.x and have installed (hopefully) all the codecs.

有人可以建议我为什么会收到此错误吗?如果是编解码器问题，我应该安装哪些编解码器(+ 版本)?如果它的其他东西坏了，有没有其他方法可以在 python 中创建动画?

Can someone please suggest as to why I get this error? If its a codecs issue, which codecs (+versions) should I install? If its something else that's broken, is there an alternative for creating animations in python?

推荐答案

遇到了同样的问题....过了一会儿设法让它工作.

Had the same problem....managed to get it to work after a little while.

要做的是按照安装 FFmpeg 的说明进行操作 - 这是(至少在 Windows 上)您需要在环境变量中设置路径的一组可执行文件

Thing to do is follow instructions on installing FFmpeg - which is (at least on windows) a bundle of executables you need to set a path to in your environment variables

从 ffmpeg.org 下载
