Как реализовать показ youtube видео в webview с версии 4.4.4?

Для приложения понадобился встроенный браузер. Суть - показ в разделе "Помощь" различное видео(не только youtube - так что использовать youtube api нет смысла.). Никаких autoplay не надо. Просто открыть ссылку в браузере и пусть пользователь сам решает смотреть/не смотреть.

в версиях выше 4.4.4 после нажатия на play получаю такое
И пытается загрузить до бескончености

Спасибо!
