mp3 file not found when generating deck

[anawfulfeeling]

After having some initial problems with ffmpeg not being found on Mac (the addon doesn't check /opt/homebrew/bin/ffmpeg where ffmpeg will be installed using Brew), I was unable to run the addon using the following video: https://www.youtube.com/watch?v=mapbKTJ9aBs

I tried another video and hit the same error: https://www.youtube.com/watch?v=r0io_xgmcSs

Probably caused by invalid characters like ":" in title.

Sanitazing filename in ffmpeg.py could solve the issue:

import re

class Ffmpeg:
    def __init__(self, subtitle, video_path, video_title):
        self.time_diff = (subtitle.time_end - subtitle.time_start).total_seconds()
        sanitized_title = re.sub(r'[^\w_ -]', '_', video_title)
        media_path_prefix = Path(tempfile.gettempdir()).joinpath(
            f"{sanitized_title}_\
                  {str(subtitle.time_start).replace('.','_').replace(':','_')}_\
                  {str(self.time_diff).replace('.','_').replace(':','_')}",
        )
