Thanks for the report @rmeno12 . We have a PR to fix the exception, but you will still have the problem that you do not have ffmpeg installed so will not be able to create an mp4 for you.

Closed by #16965.

I seem to be having the same problem, any idea when the fix will come out? Is there any workaround? Is there an older version without this problem? I am using ArtistAnimation with the same problem on version 3.2.1.

3.2.2 will be out with the release candidate for 3.3.0, either end of this week or some time next week.

Its still not around.

We are a mostly volunteer organization and sometimes release dates slip. Any help clearing the remaining issues for 3.2.2 and 3.3.0 would be appreciated and expedite the process.

I'm using 3.2.1 and already pip install ffmpeg but when I run the following code

import matplotlib.animation as manimation
manimation.writers.list()

I still only got ['pillow', 'html']. Is there an easy way to install ffmpeg on Windows rather than setting system var and am I missing something?

@StevenLi-DS This fix is on 3.2.2 to get the better fallback behavior, but that won't solve your installation problem.

ffmpeg is usually a system dependency (the ffmpeg package on pypi is a python wrapper that calls out via sub-process). I am not a regular windows user, but I suggest starting at https://ffmpeg.org/download.html

I am using matplotlib 3.3.2 on windows and still get the error "TypeError: 'str' object is not callable" when using animation save. Any help would be appreciated :)

Can you open a new issue with a minimal example that causes the issue?

I'm getting the same issue as @ndavoudi

We can't fix an error if we can't trigger it. Can someone provide a MWE so we can try and fix?

I think this is just related to ' fallback behavior', perhaps? When reinstalled ffmpeg the issue was resolved. So there is something up with the pillow fallback perhaps?

So the MWE would be to uninstall ffmpeg and see if the fallback behavior acts as expected?

Anyway the issue is resolved for me currently.

I am getting the same "TypeError: 'MovieWriterRegistry' object is not an iterator" message, does anyone know if this bug has now been fixed and therefore whether it's a problem at my end?

@bcalvr if it is exactly the same repro as the original issue we can re-open. If its different, then please open a new issue with the reproducible example. Also it looks like stating whether you have ffmpeg or not may be helpful. Perhaps we have a broken untested fallback?

I think I have managed to solve the problem - it was to do with the location of my ffmpeg installation. Thank you for the response though! I am now able to export animations to video files, but I am still struggling with getting them to play inline in Atom!

Installation of FFmpeg in anaconda(from https://blog.csdn.net/Linli522362242/article/details/121313449):
conda install -c conda-forge ffmpeg
`import matplotlib.pyplot as plt
import matplotlib.animation as animation
import random
from IPython.display import HTML

fig = plt.figure()
ax1 = fig.add_subplot(1, 1, 1)
x = [random.randint(0, 10) for _ in range(5)]
y = [random.randint(0, 10) for _ in range(5)]

def ani_func(i):
x.append(random.randint(0, 10))
y.append(random.randint(0, 10))
ax1.clear()
ax1.plot(x, y)

ani = animation.FuncAnimation(fig, ani_func, frames=10, repeat=False)
plt.show()
ani.save('test2.mp4')
HTML( ani.to_html5_video() )`

I am using matplotlib 3.3.2 on windows and still get the error "TypeError: 'str' object is not callable" when using animation save. Any help would be appreciated :)
