I need to find some other sources like useful videos or webpages

Once you reach a certain point, you don't really learn from anything explicitly, more like you discover on your own about the language. There are some insanely useful resources to help with that, though.
http://www.cplusplus.com/reference/
http://en.cppreference.com/w/
These two sites have documentation for the entire standard C/C++ libraries. They are very useful for learning about new features of the language. Both provide the same information, but have slightly different layouts and formatting. Some will say cppreference is more official, but it's really your preference.
http://devdocs.io/cpp/ also seems to be a new reference site, but I am not familiar with it like I am the others.
http://stackoverflow.com/
https://www.quora.com/
These are Q&A sites. Stackoverflow (and by extension, stackexchange in general) is by far the most used Q&A site for programming related questions. if you have a question, no matter how obscure you think it may be, look through SO for related questions and I guarantee you someone will have an answer for you (which will also have a 75% chance of the question being closed as off-topic or not constructive). Quora is a general Q&A site that has a lot of programming related questions as well.
But really, the best way to learn is to play around and push your boundaries on your own. Give yourself interesting projects and push your limits. The more you run into problems and attempt to overcome them, the more you'll learn.
