Error exporting animation ffmpeg - Matplotlib
4 décembre 2020, par jonboyI'm having issues with exporting an animation using python through anaconda on a Mac. I'm getting the following
RuntimeError
.

RuntimeError: Requested MovieWriter (ffmpeg) not available



Looking at other questions, the main options are to install
ffmpeg
via conda :

conda install -c conda-forge ffmpeg



Or designate the path :


plt.rcParams['animation.ffmpeg_path'] = '/usr/local/bin/ffmpeg'



The second option just returns the same
RuntimeError
. The first option returns a separate error :

BrokenPipeError: [Errno 32] Broken pipe


During handling of the above exception, another exception occurred:

Traceback (most recent call last):

 File "/Users/person/opt/anaconda3/lib/python3.8/site-packages/matplotlib/animation.py", line 1152, in save

Chasing up this error then refers me back to uninstalling the
ffmpeg
package. But this just leads to the initial error statingffmpeg
isn't available.
