In fact, no need for perl...

	#!/bin/bash

	if [ $# -eq 0 ]; then
		echo usage: $(basename "$0") "filename [...]"
		exit 1
	fi

	for file in "$@"
	do
		output=$(mplayer -identify -vo null -ao null -frames 0 "$file" 2>&1)

		width=
		height=
		[[ "$output" =~ "ID_VIDEO_WIDTH=([0-9]+)" ]] && width=${BASH_REMATCH[1]}
		[[ "$output" =~ "ID_VIDEO_HEIGHT=([0-9]+)" ]] && height=${BASH_REMATCH[1]}

		if [ -z "$width" -o -z "$height" ]; then
			echo "$file: unknown size"
		else
			echo "$file: ${width}x$height"
		fi
	done
