在 OpenClaw 中安装
/install video-frames-extractor
功能描述
Extract frames or short clips from videos using ffmpeg.
使用说明 (SKILL.md)
Video Frames (ffmpeg)
Extract a single frame from a video, or create quick thumbnails for inspection.
Quick start
First frame:
{baseDir}/scripts/frame.sh /path/to/video.mp4 --out /tmp/frame.jpg
At a timestamp:
{baseDir}/scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpg
Notes
- Prefer
--timefor “what is happening around here?”. - Use a
.jpgfor quick share; use.pngfor crisp UI frames.
安全使用建议
This skill is a small, coherent wrapper around ffmpeg. Before installing: ensure you are comfortable installing ffmpeg via Homebrew; the script will write the file you specify (it will create the output directory), so avoid pointing --out to sensitive system paths; don't feed untrusted/malicious video files to ffmpeg on sensitive hosts (keep ffmpeg up to date to receive security fixes). If you run on a platform without Homebrew, you'll need to provide ffmpeg by other means.
功能分析
Type: OpenClaw Skill
Name: video-frames-extractor
Version: 1.0.0
The skill bundle is a legitimate utility for extracting video frames using ffmpeg. The core logic in `scripts/frame.sh` is a straightforward wrapper that handles arguments safely using double quotes to prevent shell injection, and the installation instructions in `SKILL.md` use standard package managers (Homebrew) to satisfy dependencies.
能力评估
Purpose & Capability
Name/description (extract frames with ffmpeg) match the requirements and code. The only required binary is ffmpeg and the included script invokes ffmpeg to extract frames — nothing else is requested or installed.
Instruction Scope
SKILL.md and scripts/frame.sh only read the user-supplied input video file and write the specified output path. There are no network calls, no reads of unrelated files or environment variables, and no broad discretion (script takes explicit args).
Install Mechanism
Install spec uses Homebrew formula 'ffmpeg', a standard and expected way to obtain ffmpeg on macOS. No arbitrary downloads or extract-from-URL steps are present.
Credentials
No environment variables or credentials are requested. The script does not access any secrets or other config paths.
Persistence & Privilege
Skill does not request persistent/always-on presence (always: false) and does not modify other skills or global agent settings. Autonomous invocation remains enabled (platform default) but is reasonable for a user-invoked utility.
