No, || means "any of", see [1]. And I believe in that case portage will translate it to "any-of" or something like that. These are just nested conditionals. It can be confusing even for someone with programming background. I suppose portage could translate that into a more human friendly form but with many nesting levels it will get ugly any way you put it. And yes, dec_av2 is what he needs (unless he doesn't need x264 and x265 support). I was just clearing the point about the meaning of the message.
