For analysis lectures this guy is hard to find in the Youtube algorithm but has the best analysis lectures you'll ever find https://www.youtube.com/playlist?list=PL22w63XsKjqxqaF-Q7MSy... many go well with Terence Tao's book or whatever analysis text you're currently doing.

As for OCW it is missing a lot of content that you can find if you look at the class page on stellar for prev semesters, for whatever reasons they're not allowed on there but you can still find full lectures (until they lockdown that access too)
