douyin-video FAQ

Do I need an API key to download videos?

No. Getting video information and downloading videos requires no API key. The API key is only needed for the speech recognition transcript extraction feature.

What is the output directory structure?

Each video is saved in a folder named by its video ID. Inside are transcript.md (markdown file with metadata and extracted text) and optionally the video file itself if --save-video is used.

Why is transcript extraction failing?

Ensure your API_KEY environment variable is set correctly with a valid SiliconFlow API key that has sufficient quota. Also verify FFmpeg is properly installed on your system.

Can I use this programmatically in Python?

Yes. Import the functions (get_video_info, download_video, extract_text) from douyin_downloader.py and call them directly in your code with appropriate parameters.

What Douyin link formats are supported?

The tool supports standard Douyin share links (typically https://v.douyin.com/xxxxx/) and complete Douyin video URLs. Ensure the link is valid and accessible.

环境要求

依赖安装

pip install requests ffmpeg-python

系统要求

  • FFmpeg 必须安装在系统中 (用于音视频处理)
  • macOS: brew install ffmpeg
  • Ubuntu: apt install ffmpeg

API 密钥配置 (仅文案提取需要)

文案提取功能使用硅基流动 API, 需要设置环境变量:

export API_KEY="your-siliconflow-api-key"

获取 API 密钥: https://cloud.siliconflow.cn/

使用方法

方法一: 使用脚本 (推荐)

# 获取视频信息和下载链接 (无需 API 密钥)
python douyin_downloader.py --link "抖音分享链接" --action info

# 下载视频到指定目录
python douyin_downloader.py --link "抖音分享链接" --action download --output ./videos

# 提取视频文案并保存到文件 (需要 API_KEY 环境变量)
python douyin_downloader.py --link "抖音分享链接" --action extract --output ./output

# 提取文案并同时保存视频
python douyin_downloader.py --link "抖音分享链接" --action extract --output ./output --save-video

# 安静模式 (减少输出)
python douyin_downloader.py --link "抖音分享链接" --action extract --output ./output --quiet

输出目录结构

提取文案后, 每个视频会保存到独立文件夹:

output/
├── 7600361826030865707/      # 视频ID为文件夹名
│   └── transcript.md         # Markdown 格式文案文件
├── 7581044356631612699/
│   ├── transcript.md
│   └── 7581044356631612699.mp4  # 使用 --save-video 时保存
└── ...

## 文案内容

(语音识别的文字内容)

方法二: 在 Python 代码中调用

from douyin_downloader import get_video_info, download_video, extract_text

info = get_video_info("抖音分享链接")
print(f"视频ID: {info['video_id']}")
print(f"标题: {info['title']}")
print(f"下载链接: {info['url']}")

# 下载视频
video_path = download_video("抖音分享链接", output_dir="./videos")

# 提取文案并保存到文件
result = extract_text("抖音分享链接", output_dir="./output")
print(f"文案已保存到: {result['output_path']}")
print(result['text'])
