Custom output location

{baseDir}/scripts/extract-audio.py video.mp4 -o ~/Music/my-song.mp3

Download YouTube video (keep it)

{baseDir}/scripts/extract-audio.py "https://youtube.com/watch?v=..." --video-only --keep-video

YouTube Support

For YouTube videos, the tool uses yt-dlp to extract audio directly when possible. This is faster and more efficient than downloading the full video.

YouTube Limitations

YouTube actively blocks automated downloads. If you encounter errors:

  1. Update yt-dlp: pip3 install -U yt-dlp
  2. Try different URLs - Some videos have stricter restrictions
  3. Use --video-only to download the video first, then extract
  4. Browser extension - Use a YouTube downloader extension, then process the file

Common YouTube Errors

  • 403 Forbidden: YouTube blocked the request. Try updating yt-dlp or use a different video.
  • Sign in required: Video requires authentication. Use browser download instead.
  • Timeout: Video too large or connection slow. Try --video-only first.

Technical Details

  • Uses ffmpeg for audio extraction
  • Uses yt-dlp for YouTube downloads
  • Downloads to temporary directory, auto-cleanup by default
  • Preserves original audio codec when possible
  • Progress indicators for long operations
