[Errno 3] No such process : on Windows Sub Linux (ubuntu 16.x)

[Max452]

I have installed Moviepy & ffmpeg:
when I run this :

test_clip = VideoFileClip("test.mp4")

I have this error :

I've tested this  : 
`ffmpeg -i test.mp4`
and the result seems to work

Hope you find why this doesn't work

I am also having this issue on WSL Ubuntu 16.x.

Any update on this? I'm having the same problem. Thanks

[michaeltoohig]

Same here.

[cundesi]

Same here.

I am seeing the same thing with WSL 18.04, python 3.6, for what it's worth. Looking at a potential fix right now.

[Overdrivr]

It looks like this has been fixed by #927, feel free to reopen if you encounter this bug again (please note it's live on master but not released yet on pypi)
