  • Can't save matplotlib animation (ffmpeg)

    25 mai 2014, par renger

    I am trying to get a simple animation saved using ffmpeg. I followed a tutorial to install ffmpeg, and I can now access it from the command prompt.

    Now I run this piece of code :

    import numpy as np
    
from matplotlib import pyplot as plt
    
from matplotlib import animation
    

    
fig = plt.figure()
    
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
    
line, = ax.plot([], [], lw=2)
    

    
def init():
    
    line.set_data([], [])
    
    return line,
    

    
def animate(i):
    
    x = np.linspace(0, 2, 1000)
    
    y = np.sin(2 * np.pi * (x - 0.01 * i))
    
    line.set_data(x, y)
    
    return line,
    

    
anim = animation.FuncAnimation(fig, animate, init_func=init,
    
                               frames=200, interval=20, blit=True)
    

    
mywriter = animation.FFMpegWriter()
    
anim.save('mymovie.mp4',writer=mywriter)
    

    
plt.show()

    I get this error :

    Traceback (most recent call last):

    startupinfo)
    
WindowsError: [Error 2] Het systeem kan het opgegeven bestand niet vinden
    
</module></module></stdin>

    The last dutch sentence does mean something like : The system can’t find the specified file.

    What do these errors mean, and how can I solve them ?

    Best,
