Comment (by WebTrooper):

 Just to be clear, you can add the following to twentyseventeen or a
 childtheme thereof, to the functions.php.

 {{{#!php
 function bc_twentyseventeen_custom_header_setup() {

         remove_theme_support( 'custom-header');

         add_theme_support( 'custom-header', apply_filters(
 'twentyseventeen_custom_header_args', array(
                 'default-image'      => get_parent_theme_file_uri(
 '/assets/images/header.jpg' ),
                 'width'              => 2000,
                 'height'             => 1200,
                 'flex-height'        => false,
                 'flex-width'         => false,
                 'video'              => true,
                 'wp-head-callback'   => 'twentyseventeen_header_style',
         ) ) );

 }
 add_action( 'after_setup_theme', 'bc_twentyseventeen_custom_header_setup',
 11 );
 }}}
