Analyze Video with Qwen

Overview

使用阿里云 Qwen 3.5 Plus 多模态模型对视频进行智能分析。支持本地视频文件和远程 URL,可自定义分析问题和视频抽帧频率(FPS)。

何时使用

  • 需要理解视频内容、场景描述
  • 需要视频中的动作识别、物体检测
  • 需要生成视频摘要或分析报告
  • 需要分析远程在线视频

快速用法

分析本地视频

默认设置分析视频:

python scripts/analyze.py /path/to/video.mp4

自定义提示词:

python scripts/analyze.py /path/to/video.mp4 --prompt "请详细描述视频中的每个场景"

自定义抽帧频率(FPS越高,分析越精细):

python scripts/analyze.py /path/to/video.mp4 --fps 5

分析远程视频 URL

直接分析远程视频:

python scripts/analyze.py https://example.com/video.mp4

组合使用:

python scripts/analyze.py /path/to/video.mp4 --fps 3 --prompt "视频中出现了哪些人物和物体?"
python scripts/analyze.py https://example.com/video.mp4 --fps 4 --prompt "请详细描述视频场景"

参数说明

参数说明默认值必填
video_source视频文件路径或远程 URL(支持 http/https)-是
--fps抽帧频率,每秒抽取的帧数2否
--prompt分析提示词"这段视频描绘的是什么景象?"否

配置

API Key 从 ~/.openclaw/openclaw.json 的 skills.dashscope.apiKey 字段读取。

如未配置,请添加以下内容:

{
  "skills": {
    "dashscope": {
      "apiKey": "your-dashscope-api-key"
    }
  }
}

备注

  • 本地视频路径可以是绝对路径或相对路径
  • 远程视频 URL 必须是可公开访问的直链
  • FPS 越高,API 调用成本越高,建议根据视频长度和需求调整
