Oodle Compressor 2.5.2 by RAD Game Tools
This is a wrapper to use it with freearc and stdio
Comprssion levels:
None = 0,
SuperFast = 1,
VeryFast = 2,
Fast = 3,
Normal = 4,
Optimal1 = 5,
Optimal2 = 6,
Optimal3 = 7,
Count = 8
None don't compress, just copy raw bytes
SuperFast super fast mode, compression can be very poor; try VeryFast first
VeryFast fastest LZ mode for normal use, good for runtime encoding
Fast fast - good for daily use
Normal standard medium speed LZ mode
Optimal1 optimal parse level 1 (faster optimal encoder)
Optimal2 optimal parse level 2 <- recommended
Optimal3 optimal parse level 3 (slower optimal encoder)
Compression methods:
None = 3,
Kraken = 8,
Leviathan = 13,
Mermaid = 9,
Selkie = 11,
LZNA = 7,
BitKnit = 10,
LZB16 = 4,
Hydra = 12,
LZBLW = 5,
LZH = 0,
LZHLW = 1,
LZNIB = 2,
LZA = 6,
Count = 14
None None = memcpy
Kraken Fast decodes, high compression, amazing! NOTE : LARGE QUANTUM
Leviathan Leviathan = Kraken's big brother with higher compression. NOTE : LARGE QUANTUM
Mermaid Mermaid is between Kraken & Selkie - crazy fast, still decent compression. NOTE : LARGE QUANTUM
Selkie Selkie is a super-fast relative of Mermaid. Faster than LZB16/LZ4 but more compression. NOTE : LARGE QUANTUM ; NOTE : Selkie will show up as Mermaid data in the decoder
LZNA LZNA : the highest compression option in Oodle, comparable to LZMA (7zip) but much faster to decode
BitKnit BitKnit ; usually close to LZNA compression levels but faster. Particularly great on some types of structured binary, such as structs of DWORD/float.
LZB16 LZB16 = LZ-Bytewise ; 64k window ; fast, low compression. Generally prefer Selkie unless you need the 64k window
Hydra Hydra, the many-headed beast = Kraken, Mermaid, or Selkie
LZBLW OLD : LZBLW = LZB-LargeWindow ; often a free win over LZB16
LZH OLD : LZH , 128k sliding window ; generally use LZHLW instead
LZHLW OLD : LZH-LargeWindow ; fast to decode, good compression
LZNIB OLD : LZ-Nibbled ; fast to decompress + medium compression
LZA DO NOT USE : LZA = LZ-Arithmetic ; use LZNA instead
Multithreading is done by chunks, remember that highest RAM usage for decompression = Chunksize*2*threads
May contain bugs, not fully tested with multicore cpus, I only have 2 cores
