There are two methods of AES encryption, which is used for cupertinostreaming to iOS devices only.

Right, I don’t think so either. I have never heard of it and we have two AES methods to choose from

Same result, and internal method is easier to implement, yes.

OK but at a glance it appears i would not need the zencoder encryption, correct?

1. is int VS ext exactly the same end result

2. am i correct that the int method requires less coding (or custom coding) …because its all done by wowza
