We do tons of operations on 3 fields (array of codecs, len of array, selected code) which can be isolated. Right now, we are using APIs which somehow require structs 2-3 levels of encapsulation above the ones really required, which makes all code totally entangled, difficult to understand and prone to errors when changing stuff in deeply nested structs. A prove of this is how this patch affects a lot of lines in lots of places. Change-Id: Id7db7ab01d56b7fa2415123b604375e48c82ab25
