Update yt-dlp periodically to keep up with site changes: yt-dlp -U or pip install -U yt-dlp.

Tips

• Always use --merge-output-format mp4 to avoid ending up with .webm or .mkv files.

• Use --no-download with --dump-json for metadata-only queries -- no files written to disk.

• If a download fails with HTTP errors, update yt-dlp first (yt-dlp -U).

• Use -f "bestvideo[height<=720]+bestaudio" to save bandwidth when full resolution is not needed.

• yt-dlp automatically handles rate limiting and retries.

• The --dump-json output includes title, duration, uploader, view_count, description, formats, subtitles, and much more.

Troubleshooting

• "yt-dlp: command not found": Install it (pip install yt-dlp) and ensure your PATH includes pip's bin directory.

• "ffmpeg: command not found": Install ffmpeg. Without it, downloads fail when video and audio are separate streams (common on YouTube for HD).

• Downloads fail or return errors: Run yt-dlp -U to update. Sites change frequently and yt-dlp ships fixes regularly.
