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

Hope this helps someone - even after a while after the question - good luck
