SDL::Video can be diffficult to install and use. Here's a list of dependencies and a Makefile.PL that I used to install SDL. The documentation's SYNOPSIS gives a working example of usage. Here it is: 
#!/usr/bin/perl

use strict;
use warnings;
use SDL;
use SDL::Video;
use SDL::Surface;
use SDL::Rect;

my $screen_width  = 800;
my $screen_height = 600;

SDL::init(SDL_INIT_VIDEO);

my $screen_surface = SDL::Video::set_video_mode(
$screen_width, $screen_height, 32, SDL_ANYFORMAT);

my $mapped_color = SDL::Video::map_RGB(
   $screen_surface->format(), 0, 0, 255);
   
SDL::Video::fill_rect($screen_surface,
   SDL::Rect->new(
   $screen_width / 4, $screen_height / 4,   
   $screen_width / 2, $screen_height / 2),
   $mapped_color);
   
SDL::Video::update_rect(
   $screen_surface, 0, 0, 
   $screen_width,
   $screen_height);
   
sleep(5);

SDL::quit();
