Then simply ask Claude: "download this xiaohongshu video: "

Standalone Usage

python scripts/download_xiaohongshu.py "https://www.xiaohongshu.com/explore/VIDEO_ID"

Supported URL Formats

Tip: Always copy the full share URL (including xsec_token parameters) from Xiaohongshu’s share button for best results.

Usage

Basic Download (v1.0 compatible)

python scripts/download_xiaohongshu.py "URL"

Output: ~/Downloads/ [].mp4

Full Resource Pack

python scripts/download_xiaohongshu.py "URL" --full

Output:

~/Downloads//
├── video.mp4          # Original video
├── audio.mp3          # Extracted audio (ffmpeg)
├── subtitle.vtt       # WebVTT subtitles
└── transcript.txt     # Plain text transcript

AI Summary (via Claude Skill)

Ask Claude: "帮我下载并总结这个小红书视频: "

Output adds:

~/Downloads//
├── ...
├── .meta.json         # Video metadata
└── summary.md         # AI-generated structured summary

Options

Examples

# Download with default settings (best quality, Chrome cookies)
python scripts/download_xiaohongshu.py "https://www.xiaohongshu.com/explore/69821980000000000e03c95f"

# Download in 720p
python scripts/download_xiaohongshu.py "URL" -q 720p

# Download to a specific directory
python scripts/download_xiaohongshu.py "URL" -o ~/Videos/

# Download audio only
python scripts/download_xiaohongshu.py "URL" -a

# Full resource pack
python scripts/download_xiaohongshu.py "URL" --full

# Full resource pack with AI summary metadata
python scripts/download_xiaohongshu.py "URL" --summary

# List available formats
python scripts/download_xiaohongshu.py "URL" --list-formats

# Use Firefox cookies instead of Chrome
python scripts/download_xiaohongshu.py "URL" --browser firefox

Subtitle Acquisition Strategy

The full resource pack mode uses a 3-tier strategy to obtain subtitles:

1. Manual subtitles — Tries to download creator-uploaded subtitles via yt-dlp --write-subs
2. Auto-generated subtitles — Tries platform auto-generated subtitles via yt-dlp --write-auto-subs
3. Whisper transcription — Falls back to local speech-to-text using faster-whisper

The Whisper fallback uses intelligent silence-based audio splitting and parallel multi-core transcription for faster processing.

Troubleshooting

How It Works

This tool leverages yt-dlp’s built-in XiaoHongShu extractor which:

1. Downloads the Xiaohongshu webpage and extracts window.__INITIAL_STATE__ JSON
2. Parses video metadata including multiple codec formats (H.264, H.265/HEVC, AV1)
3. Uses browser cookies (web_session) to authenticate with the platform
4. Downloads the video stream and merges audio/video if needed via ffmpeg

In full resource pack mode, the tool additionally:

5. Extracts audio to MP3 using ffmpeg
6. Acquires subtitles via the 3-tier strategy
7. Generates a plain-text transcript from the subtitles
8. (Optional) Prepares metadata for AI summary generation

字幕获取策略

完整资源包模式采用三级策略获取字幕：

1. 手动字幕 — 尝试通过 yt-dlp --write-subs 下载创作者上传的字幕
2. 自动生成字幕 — 尝试通过 yt-dlp --write-auto-subs 获取平台自动生成的字幕
3. Whisper 转录 — 使用 faster-whisper 进行本地语音转文字

Whisper 回退方案采用智能的基于静音点的音频切割和多核并行转录，以加快处理速度。

常见问题

工作原理

本工具利用 yt-dlp 内置的小红书提取器：

1. 下载小红书网页，提取 window.__INITIAL_STATE__ JSON 数据
2. 解析视频元数据，包括多种编码格式（H.264、H.265/HEVC、AV1）
3. 使用浏览器 Cookie（web_session）进行平台身份验证
