Matplotlib-Animation "No MovieWriters Available"
Solution 1
Had the same problem....managed to get it to work after a little while.
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
http://www.wikihow.com/Install-FFmpeg-on-Windows
Hope this helps someone - even after a while after the question - good luck
Solution 2
For fellow googlers using Anaconda, install the ffmpeg package:
conda install -c conda-forge ffmpeg
This works on Windows too.
(Original answer used menpo
package owner but as mentioned by @harsh their version is a little behind at time of writing)

I know this question is about Linux, but in case someone stumbles on this problem on Mac like I did here is the solution for that. I had the exact same problem on Mac because ffmpeg
is not installed by default apparently, and so I could solve it using:
brew install yasm
brew install ffmpeg
Solution 4
Had the same problem under Linux. By default the animate.save method is using ffmpeg but it seems to be deprecated. https://askubuntu.com/questions/432542/is-ffmpeg-missing-from-the-official-repositories-in-14-04
Solution: Install some coder, like avconv or mencoder. Provide the alternative coder in the call:
ani.save('the_movie.mp4', writer = 'mencoder', fps=15)
Solution 5
If you are using Ubuntu 14.04 ffmpeg
is not available. You can install it by using the instructions directly from https://www.ffmpeg.org/download.html.
In short you will have to:
sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg gstreamer0.10-ffmpeg
If this does not work maybe try using sudo apt-get dist-upgrade
but this may broke things in your system.

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.
Using either of the examples:
- http://matplotlib.org/examples/animation/moviewriter.html
- http://matplotlib.org/examples/animation/basic_example_writer.html
results in the error "RuntimeError: No MovieWriters available!"
Im using matplotlib version 1.3.x and have installed (hopefully) all the codecs.
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?
