description	Extracts all key frames from a video file into a specified output directory using FFmpeg.

Overview

This skill extracts keyframes (I-frames) from video files into individual PNG files. This is useful for object detection over time.

Usage

To extract keyframes as PNG files, use the following command:

ffmpeg -i <input_file> -vf "select='eq(pict_type,PICT_TYPE_I)'" -fps_mode vfr -vsync vfr /root/keyframes_%03d.png

• -i: Input video file.
• -vf "select='eq(pict_type,PICT_TYPE_I)'": Select only I-frames.
• -fps_mode vfr: Specifies variable frame rate mode for keyframes.
• -vsync vfr: Maintains synchronization by setting variable frame rate.
• /root/keyframes_%03d.png: Output filename pattern.
