Answer 1

Add post_type to the query. 'post_type' => 'video'

function my_vc_shortcode( $atts ) {
return '
    <ul class="categories">
         '.wp_list_categories( array(
            'post_type' => 'video',
            'orderby' => 'name',
            //'post_type' => 'video', 
            'include' => array(20216, 20375, 20216),
            'title_li' => '',
        ) ).'
    </ul>
    ';
}
add_shortcode( 'my_vc_php_output', 'my_vc_shortcode');
