Videos not working on phone/mobile view

Hi I have embedded youtube videos using Astrid video widget (and another one) at https://webmobapps.com/about and https://webmobapps.com/silent-salesman but they are not working in mobile view (at least not on Samsung Galaxy 320px phone) They work on desktop but not on phone, doeas anyone know why this might be?
Many Thanks
