Shortcode not working anymore

I used this code and was working fine:

function vidbg_front_page() {

  // Your conditional for front page
  if( ! is_front_page() ) {
    return;
  }

  // Your Video Background shortcode
  echo do_shortcode( '[vidbg container="body" mp4="#" webm="#" poster="#" muted="true" loop="true" overlay="false" overlay_color="#000" overlay_alpha="0.3"]' );
}
add_action( 'wp_footer', 'vidbg_front_page' );

Now after the update, it’s not working anymore.

What has changed in the new version??
