How do I handle 'nsig extraction failed' errors?

The skill guides you through updating yt-dlp, installing a PO token provider, or using the Android client workaround to bypass nsig extraction issues.

Why can I only download 360p videos?

This usually happens due to missing PO tokens or an outdated yt-dlp installation. This skill provides a step-by-step PO token provider setup to unlock 1080p and 4K resolutions.

Can I extract audio only?

Absolutely. The skill includes specific commands to extract high-quality audio from videos and save them directly as MP3 files using ffmpeg.

Does this support protected HLS streams?

Yes, it includes specialized ffmpeg workflows for downloading .m3u8 streams that require Referer, Origin, or User-Agent authentication headers to bypass 403 errors.
