Thanks for checking that. So "is finished: false" is telling us that not all of the input was compressed. So I think the right thing is to do the deflate in a loop until there is more input to compress, the inflate probably needs the same. Your original proposal was to make the output buffer larger and I suspect that is just working around a threshold or block size used by the accelerator.
