@k00dez - create_thumb() function can be called from PHP code to resize image in the filesystem. For example after image is upladed to the Web server. Or you can create a small PHP code to process all images in the current directory. Imagine you have a list of big images saved from camera and you want to reduce image resolution at once. Yes it can be done with PhotoShop, GIMP, IrfanView - and some of them have scripting option to automate resizing process ... By all means, it was easier for me to write a PHP code and run it from command line. Here are few PHP lines to resize all images in current directory:

// read files inside current directory
$files = scandir('.');
// open loop for all fetched files in current directory 
foreach ($files as $file){
	// process only jpg files
	if (substr($file, -3) == 'jpg'){
		// proportionally resize images to fit in 800x800 box
		create_thumb($file, 800);
	}
}

@karthi - This post is about image resizing with PHP. As I can read from your comment, input for ffmpeg is a "video file" not an image. So this is not closely related to the shown PHP solution. Anyway, thank you for posting a comment, it will be surely useful. Cheers!
