Question

我正在尝试调用matplotlib.animation.ArtistAnimation来从一系列png图像制作动画，但是我得到一个连接到ffmpeg的错误。我在我的Ubuntu 14.04上安装了Anaconda。我得到的错误消息是：

UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
  warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')
/home/ohm/anaconda2/lib/python2.7/site-packages/matplotlib/animation.py:782: UserWarning: MovieWriter ffmpeg unavailable
  warnings.warn("MovieWriter %s unavailable" % writer)
...
  File "/home/ohm/anaconda2/lib/python2.7/site-packages/matplotlib/animation.py", line 810, in save
    writer.grab_frame(**savefig_kwargs)
  File "/home/ohm/anaconda2/lib/python2.7/contextlib.py", line 24, in __exit__
    self.gen.next()
  File "/home/ohm/anaconda2/lib/python2.7/site-packages/matplotlib/animation.py", line 196, in saving
    self.finish()
  File "/home/ohm/anaconda2/lib/python2.7/site-packages/matplotlib/animation.py", line 389, in finish
    + ' Try running with --verbose-debug')
RuntimeError: Error creating movie, return code: 1 Try running with --verbose-debug

我已经尝试了sudo apt-get install ffmpeg，但没有这样的套餐。有人知道我错过了什么方案吗？

Answer 1

conda update conda
conda install --channel https://conda.anaconda.org/conda-forge ffmpeg

matplotlib动画由于ffmpeg不可用而导致ArtistAnimation失败
