FFMPEG not downloaded

Until two days ago, imageio was downloading ffmpeg correctly. It is not doing so anymore.

Details of deployed server:

IBM Bluemix CloudFoundry App Runs Ubuntu 14.04 LTS Server Moviepy installed via pip.

Adding the line imagio.plugins.ffmpeg.download() to my python code has no effect. Also, I’m not sure why it is looking for ffmpeg exe when it is running on a linux server.

Oh yeah sorry for not addressing that. When do you run the imageio.plugins.ffmpeg.download() ? My best guess would be “not soon enough”. Can you try this ?

import imageio
imageio.plugins.ffmpeg.download()
from moviepy.editor import *

And report what happens ?

@gpantelis You don’t need to catch it. Just add these two lines at the very top of the file where you are using moviepy and you should be done.

import imageio
imageio.plugins.ffmpeg.download()

@Zulko are there any other dependencies which can raise a NeedDownloadError exception?
