tiny decompress buffer #2

kimstik commented 1 year ago

I'm looking for optimal compression with limited resources to decompress. In my case it is 16k available RAM. LZ4x of Ilya Muravyov is easily tweakable for that case. I couldn't figure out how to do it correctly for blz4 ;(

If you mean limiting the block size, there is the BLOCK_SIZE define.

I'm looking for how to reduce the back-reference window size on decoder size. LZ4 block format require 64k one. BLOCK_SIZE seems to be more related to framing - max block size inside of frame (8M)

:) got it. thanks! if (pos == NO_MATCH_POS || cur - pos > 65535 || num_chain-- == 0) {

Ah, I see -- glad you found it!
