Thanks for your answer !

I tried to use your code but it display an error and I can’t find why :
Parse error: syntax error, unexpected ‘,’ in /home/guillaummg/www/faview/wp/wp-content/themes/ffaview/functions.php on line 209

add_filter( 'posts_distinct', 'cf_search_distinct' );

// PREVENT POST THAT ALREADY EXIST
add_filter('acf/validate_value/name=lien_video', 'validate_lien_video_filter', 10, 4);
add_filter('acf/load_value/name=hidden_post_id', 'add_post_id_as_value'), 10, 3);
function add_post_id_as_value($value, $post_id, $field) {
  return $post_id;
}
function validate_lien_video_filter($valid, $value, $field, $input) {
	$post_id_field_key = 'field_569ce8b4cba44';
  if (!$valid || $value == '' || !isset($_POST['acf'][$post_id_field_key])) {
    return $valid;
  }
	// change the field key below to the field key for your 
	// hide_post_id_field field
	$post_id = $_POST['acf'][$post_id_field_key];
  global $post; 
  $args = array(
    'post_type' => 'videos',  // or your post
    'post__not_in' => array($post_id), // do not check this post
    'meta_query' => array(
      array(
        'key' => 'lien_video',
        'value' => $value
      )
    )
  );
  $query = new WP_Query($args);
  if (count($query->posts)) {
    // found at least one post that
    // already has $value
    $valid = 'There is already a post using this video';
  }
  return $valid;
}
