I am unable to save an animation using ffmpeg.
Code for reproduction
import matplotlib
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
x = []
y = []
Writer = matplotlib.animation.writers['ffmpeg']
writer = Writer(fps=15, metadata=dict(artist='Me'), bitrate=1800)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_xlim(0,500)
ax.set_ylim(0,1000)
line, = ax.plot(0,0,'r')
def AnimationFrame(i):
x.append(i)
y.append(i ** 1.5)
line.set_xdata(x)
line.set_ydata(y)
return line,
animation = FuncAnimation(fig, func=AnimationFrame, frames=range(0,200), interval = 100)
plt.show()
animation.save('im.mp4', writer=writer)Actual outcome
