My question is, how does the security depend or change if I encrypt with AES-128 in total 4-MB of Data? With Electronic Code Book Mode and Cipher Block Chaining Mode ? Does an adversary still need $2^{126}$ tries (like Wikipedia suggests) to guess the key or is it less (which in my opinion it should)? The encrypted data would be a videostream.
