Are you sure the assignment to $matches is correct as Nette\Utils\Strings::match(strval($data), '@^data:([\w/]+?);(\w+?),(.*)$@si') targeting Nette\Utils\Strings::match() seems to always return null.

        if (!$matches) {

$matches is of type null, thus it always evaluated to false.

            throw new MappingException('Given data URL is invalid.');
        }

        return new Media(base64_decode((string) $matches[3]), $matches[1]);
    }
