Hi @RozeS. I saw it also. but I start saying that, has i understand things, encapsulation is a part of abstraction, so it can't be opposite, but instead complementaries..
However, if i try to understand what the guy said,
since Abstraction consist of showing details(methods, variables..) usefull for the creation and the manipulation of objects,
and then by encapsulating objects, we're effectively hiding those details of their implementations that are not really necessary for every body to know(for them not to be modified by any other unwanted user), we can see this as if both are opposite.
Finally Encapsulation is the medium used to choose wich thing is better to be hidden,and wich one can be visible, for the Abstraction to be realised.
