Trying to remove Fairplay DRM from an iTunes audiobook I bought

[Lupine Assassin]

I've tried several methods but none of them worked. Any solutions?

To convert the audiobook to a DRM-free format involves stripping the DRM
and converting the file. Here's a simple way to do it using FFmpeg and a
tool called `libdvdcss` for DRM removal.

First, install `libdvdcss` to handle the DRM. For Windows, you might need
to download the binary from the official site.

Then, use FFmpeg to convert the audiobook:

ffmpeg -i input.m4b -codec copy output.m4a

Ensure that `libdvdcss` is properly installed and that FFmpeg can access it.
Check for any error messages during the conversion process.
