Hey! Thanks for checking the project.

Because the error message is upset about a path, the first few places I would look to solve your problem are to making sure all of your paths are correct. In order, these are the things I would look into:

1. Are you calling the script correctly? Here's how this script expects the command line arguments to look:

   $ python flac_converter.py -i /path/to/flac/Slakh2100 -o /output/path/Slakh2100_wav -c False

   Do you have an -i flag that points to the place where you downloaded Slakh2100?, is there an -o flag that exists where the output will go?

I think this is the issue you're seeing. But if it's not try this:

2. Once you've double checked those two paths then I would make sure you have ffmpeg called correctly. Here's the website for ffmpeg. Once it's installed, make sure you can call it from the command line, and then maybe try opening a python terminal and calling it using sub process.

So, on my machine, I have ffmpeg and calling it the output looks like this:

$ (base) Ethans-MacBook-Pro:~ ethanmanilow$ ffmpeg
ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers
[Lots more omitted info]

Note that your output will look slightly different because your on Windows.

Whereas when I type in something fake like fffmpeg (notice three f's), I get output like this:

(base) Ethans-MacBook-Pro:~ ethanmanilow$ fffmpeg
-bash: fffmpeg: command not found

You want to make sure your output doesn't say command not found.

Then I can make sure python can call ffmpeg like this:

(base) Ethans-MacBook-Pro:~ ethanmanilow$ python
Python 3.7.6 (default, Jan  8 2020, 13:42:34) 
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.run('ffmpeg')
ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers

This should be the same output as if I called it from the command line above.

Let me know if that helps!

Thank you!!!!

My problem was that i didnt install ffmpeg on windows.

I'm glad it solved your issue. Feel free to close this at your convenience .
