Install Ruby Dependencies: Run bundle install to install the required Ruby gems.
Install ffmpeg and youtube-dl: Ensure both ffmpeg and youtube-dl are installed and accessible in your system's PATH. These are required to fetch and process the YouTube video audio.
Discord Bot Token: You need to create a Discord bot on the Discord Developer Portal and obtain a bot token. Replace !REF_DISCORD_TOKEN in the script with your bot's token.
YouTube Video URL: The script is set up to play a specific YouTube video URL. Replace !REF_YOUTUBE_VIDEO_URL in the script with the desired YouTube video URL or modify the script to dynamically accept URLs.
Start the Bot: Run the script with ruby app.rb. Ensure your bot is added to your Discord server and has permissions to join and speak in voice channels.
Play Audio in Discord: Use the !play command in a text channel where the bot has access. The bot will join the voice channel you're currently in and start playing the audio from the specified YouTube video.
