# KB Zhihu Content Skill
|
|
|
|
**kb-zhihu-content** - Download Zhihu videos and extract content.
|
|
|
|
## Features
|
|
|
|
- Video download using **yt-dlp**
|
|
- Subtitle extraction (returns no subtitle, triggers Whisper)
|
|
- Supports `ZHIHU_COOKIE` environment variable
|
|
|
|
## Environment Variables
|
|
|
|
| Variable | Required | Description |
|
|
|----------|----------|-------------|
|
|
| `ZHIHU_COOKIE` | No | 知乎登录 Cookie (for member-only videos) |
|
|
|
|
## Commands
|
|
|
|
```bash
|
|
# Download video
|
|
python zhihu_content.py --id "12345678" --type video --output "/path/to/downloads/"
|
|
|
|
# Extract subtitle (returns no subtitle, triggers Whisper)
|
|
python zhihu_content.py --id "12345678" --type subtitle --output "/path/to/subtitles/"
|
|
```
|
|
|
|
## Output
|
|
|
|
```json
|
|
{
|
|
"success": true,
|
|
"type": "video",
|
|
"filename": "video_title.mp4",
|
|
"filepath": "/path/to/downloads/video_title.mp4",
|
|
"message": "下载完成: video_title.mp4"
|
|
}
|
|
```
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
# Already included in kb-skills repo
|
|
# Ensure yt-dlp is installed
|
|
pip install yt-dlp aiohttp
|
|
```
|
|
|
|
## How It Works
|
|
|
|
Video download uses **yt-dlp**:
|
|
1. Parses `ZHIHU_COOKIE` environment variable (optional)
|
|
2. Creates temporary Netscape-format cookie file
|
|
3. Runs `yt-dlp -f best -o <output> <url>`
|
|
4. Cleans up temporary file
|
|
|
|
## Notes
|
|
|
|
- 知乎视频通常没有官方字幕，将自动触发 Whisper 语音识别
|
|
- 视频下载需要能访问知乎（可能需要代理）
