# Extract First Frame as Poster for All Videos
# ======================================================
# This script goes through all .mp4 and .webm files in the current
# folder and extracts the very first frame as a high-quality poster image.
#
# Usage:
#   cd /home/khan/code/shahikitchen/public/videos
#   bash /home/khan/code/shahikitchen/extract-video-posters.sh
#
# Requirements:
#   - ffmpeg installed
#
# Output:
#   For butter-chicken-steam.mp4 → butter-chicken-steam-poster.jpg
#   (You can then update your menu data or code to use these posters)
# ======================================================
