pLZ4 (LZ4 Precompressor) - Test

[Razor12911]

COD Ghosts has zlib streams.

[LuzhinE]

I'll try it

Hey Razor CoD Infinite Warfare has similar files "image28.pak" it contains no streams. ... I have difficulty getting a good compression ratio with this game.
I tested pLZ4 .... is normal with files that do not contain streams you get the error :

Errorlevel=-1

ERROR: general (de)compression error in pLZ4

[ImmortalArc]

It's crashing again and again what to do?????
Arc.exe stopped working?????

[Razor12911]

How are you guys getting all these errors?

[LuzhinE]

Tested in a few files of Call of Duty Modern Warfare Remastered

58 files with a total of 10.3 GB, once compressed leaves it in 9.41 GB



It does not compress almost anything and it takes a lot of decompression waiting for the final version

thank you Razor12911

I tried it on a file from farcry primal, drop and scan for lz4 showed inflation ratio of above 600% while i got only 132%...

hey razor
what do you think of this file cls-precomp and xdelta with lz4 code used by fitgirl

[Razor12911]

Nothing special really and cls-precomp.dll is lz4.exe just renamed.

Thank you Razor for this tool.

Guys I'm doing some test on a file from "HITMAN":

chunk0.rpkg

Size: 7.31GB

I drag n drop it on DS4LZ4 scanner and it shows this:



But when I go to make the compression: plz4+srep+delta+4x4:lzma:max

I get the same result of: srep+delta+4x4:lzma:max

How is possible ? Anyone can help me ?

first: plz4 is a test version, so nothing special can be expected...
2nd... it is only inflation ratio 103%, if u want to get something from pzlib which is by the way is final version, u should at least have an inflamation ratio of 200%...

Thanks for your reply, btw that file(and other files of the game) doesn't have zlib/deflate streams. I get bigger size only with DS4LZ4 scanner.

So pzlib is useless with the files of Hitman. Doesn't exists some other precompressor for files with lz4 streams ? I already seen repack of hitman ~22GB. How is possible to compress the game ~61.5GB and to get 22GB of compressed archives ? Some repacker got some special lz4 precompressor that there is not on this forum ?

L0v3craft: Well Bro I dont have that game so I might not help properly...
have u used drop aand scan for zlib by razor... it offers various function like force detection, headerless streams and adjusting chunk...
set hederless stream detecion setting on and try to drop a file on it from Hitman, If it shows detected streams, then precomp in slow mode will not help...
use pzlib by razor with setting -m2, -c256m and try from "r# 1-9", the one level which produces best inflation in comparable to ds4pzlib use that one...
Best of Luck
