About this skill
抖音无水印视频下载和文案提取
从抖音分享链接获取无水印视频下载链接, 下载视频, 并使用语音识别提取视频中的文案, 自动保存到文件.
功能概述
- 获取下载链接: 从抖音分享链接解析出无水印视频的直接下载地址 (无需 API 密钥)
- 下载视频: 将无水印视频下载到本地指定目录
- 提取文案: 通过语音识别从视频中提取文字内容 (需要硅基流动 API 密钥)
- 自动保存: 每个视频的文案自动保存到独立文件夹 (视频ID为文件夹名)
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
└── ...
Markdown 文案格式
# 视频标题
| 属性 | 值 |
|------|-----|
| 视频ID | `7600361826030865707` |
| 提取时间 | 2026-01-30 14:19:00 |
| 下载链接 | [点击下载](url) |
---
## 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
# 获取视频信息
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'])
工作流程
获取视频信息
- 解析抖音分享链接, 提取真实的视频 URL
- 模拟移动端请求获取页面数据
- 从页面 JSON 数据中提取无水印视频地址
- 返回视频 ID, 标题和下载链接
提取视频文案
- 解析分享链接获取视频信息
- 下载视频到临时目录
- 使用 FFmpeg 从视频中提取音频 (MP3 格式)
- 调用硅基流动 SenseVoice API 进行语音识别

常见问题
无法解析链接
- 确保链接是有效的抖音分享链接
- 链接格式通常为
https://v.douyin.com/xxxxx/或完整的抖音视频 URL
提取文案失败
- 检查
API_KEY环境变量是否已设置 - 确保 API 密钥有效且有足够的配额
- 确保 FFmpeg 已正确安装
下载速度慢
- 这取决于网络条件和视频大小
- 脚本会显示下载进度
