Manim: WindowsError: [Error 2] The system cannot find the file specified

[samsamson33]

When attempting to run the example code using
python extract_scene.py example_scenes.py SquareToCircle -pl,

I get the following error:

Traceback (most recent call last):
  File "extract_scene.py", line 269, in main

Hi,

Same error showed to me today, I did sysscall tracing and problem was that I didn't have ffmpeg installed.

So try to install ffmpeg, if that didn't help, try to do system call tracing.

I have basically the same issue.

In my case:

ffmpeg is fine, I guess:

@samsamson33 have you fixed it?

@burlito could you tell me how to do sys call tracing?

[angeloyeo]

I found this solution...

In extract_scene.py file, changing the code in line 159

sp.call(commands, stdout=FNULL, stderr=sp.STDOUT)

into

sp.call(commands, stdout=FNULL, stderr=sp.STDOUT, shell=True)

will open the video file after rendering is done.

@angeloyeo It works fine except the misleading end message: "The system cannot find the path specified."

[eulertour]

Closing, as this has been resolved.
