`input`	Video file path or URL	(required)
`-o, --output`	Output audio file path	Auto-generated
`-f, --format`	Output format	mp3
`-b, --bitrate`	Audio bitrate	192k

{baseDir}/scripts/extract-audio.py "https://youtu.be/xxxxx" -f m4a

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:

Update yt-dlp: pip3 install -U yt-dlp
Try different URLs - Some videos have stricter restrictions
Use --video-only to download the video first, then extract
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
