Dalong Video Frames

这是基于ffmpeg的视频帧提取工具，核心功能是提取视频单帧或缩略图，支持提取首帧或指定时间戳的画面，可输出jpg（便于分享）或png（画质清晰）格式。典型场景包括视频内容预览、快速查看特定时段画面、制作视频缩略图。通过shell脚本调用，输入为视频文件路径，需先通过brew安装ffmpeg才能使用。

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 --time for “what is happening around here?”.
Use a .jpg for quick share; use .png for crisp UI frames.
