Sorry to disappoint you, but there is no way you can stop the video ads especially in Android devices. As these are a part of native video player module.
Ad blocker plus and other softwares of chrome finds the ad site urls from the web languages so it can trim the elements from the html. But Android application's source code and features cannot be taken control by any other applications.
Anyways when it comes to softwares there's nothing impossible so we could sit and hope for some features to block these annoying ads
