• Can I save a matplotlib animation to webm format ?

  19 septembre 2017, par Nikhil Mahajan

  I am using this example code as a test case : https://matplotlib.org/examples/animation/moviewriter.html

  In this code, they use FFMPEG to write the matplotlib animation to an .mp4 video file. Is it possible to write to a .webm format ?

  But I am not sure how to go about doing this.
