What are the best practices for efficiently extracting frames from multiple videos and converting them to JPEG images using PHP?

To efficiently extract frames from multiple videos and convert them to JPEG images using PHP, the best practice is to use a video processing library like FFmpeg. This library allows you to extract frames at specific intervals and convert them to JPEG images with minimal performance overhead.

// Path to the video files
$videoFiles = ['video1.mp4', 'video2.mp4', 'video3.mp4'];

// Loop through each video file
foreach ($videoFiles as $videoFile) {
    // Execute FFmpeg command to extract frames
    $cmd = "ffmpeg -i $videoFile -vf fps=1/5 img%03d.jpg";
    shell_exec($cmd);
}
