Wordpress custom header - error

I've got a quick question. I'm working on making a child theme of the Twentyseventeen theme, and I'm trying to override the custom_header code but I'm getting the following error: 

PHP Fatal error:  Cannot redeclare twentyseventeen_custom_header_setup() (previously declared in /Applications/MAMP/htdocs/wordpress/wp-content/themes/twentyseventeen/inc/custom-header.php:36) in /Applications/MAMP/htdocs/wordpress/wp-content/themes/twentyseventeen/inc/custom-header.php on line 52

I tried renaming the function so it would not be redeclared but that did not resolve the issue. So far I have not really added any additional code to my theme. I have also mimicked the directory structure to be the same as the parent theme:

assets functions.php inc custom_header.php index.php ...

Here are the files I have so far:

Functions.php

<?php

function twentyseventeenchild_enqueue_styles() { $parent_style = 'parent-style';

    wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style',
    get_stylesheet_directory_uri() . '/style.css',
        array( $parent_style )
    );
}
add_action( 'wp_enqueue_scripts', 'twentyseventeenchild_enqueue_styles' );

/**
* Implement the Custom Header feature.
*/
require get_parent_theme_file_path( '/inc/custom-header.php' );
?>

custom_header.php

<?php

/** * Custom header implementation * * @link https://codex.wordpress.org/Custom_Headers * * @package WordPress * @subpackage Twenty_Seventeen * @since 1.0 */

/** * Set up the WordPress core custom header feature. * * @uses twentyseventeen_header_style() */ function twentyseventeen_custom_header_setup() {

Just after I posted my question. All I had to do to is to add this code to my functions.php

$custom_header_args = array(
    'default-image' => get_theme_file_uri( '/assets/images/header.jpg' ),
    'width' => 2000,
    'height' => 1200,
    'flex-height' => true,
    'video' => true,
);
add_theme_support('custom-header', $custom_header_args);
