I’m reading the code and am having trouble figuring out is he does interleaving of blocks like CD’s or not.
I understand the Galois Field (255, 223) method he’s using, well the intent of it, but not the detailed Maths :(
I can see the code creating an array of parity symbols as well as the data, but then I lose what happens.
Looking at docs, the minimum output of the code is either 64KB or 128KB.
It’s 255*err-block-distance, and err-block-distance is forced to be > 255.
