No matter what I do it. Unable to work on RaspberryPi also.

Any help would be appreciated.

Hi @neetalshah. I see warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning). Could you try install ffmpeg first? Check this https://github.com/p0n1/epub_to_audiobook?tab=readme-ov-file#filenotfounderror-errno-2-no-such-file-or-directory-ffmpeg. On Windows, you may need to download the ffmpeg binary and add it to the system PATH.

thank you so much!
