Decompressing problems
 
1 Attachment(s)
hi
i was trying a method [srep64+pzlib:m3f:a64:d1g+nz] it compressed assassins creed unity 43 gigabytes to 20 kilobyte archive the archive is healthy and i can open it with freearc
the problem is i tried almost all unpacking makers here
but nothing
it either gives an known compression method [srep64] while the arc.ini is clean and good
or don't decompress any thing and exit

[External compressor:nz]
;header = 0 -cc = CM algo -cO=BWT algo ;testing = nz:r:v:cc:m8g:br512m:bw512m:p4:t0:nm
packcmd = nz64 a -r -v -cc -m16g -br512m -bw512m -p4 -t0 -nm $$arcpackedfile$$.tmp.nz $$arcdatafile$$.tmp
unpackcmd = nz64 x -m13g -t8 -p0 $$arcpackedfile$$.tmp.nz $$arcdatafile$$.tmp
datafile = $$arcdatafile$$.tmp
packedfile = $$arcpackedfile$$.tmp.nz

[External compressor:srep64]
header = 0
packcmd = srep64 {options} -m3f -d1g -a2 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep64 {options} -d -s -- <stdin> <stdout>

[External compressor:pzlib]
header = 0
packcmd = pzlib e -m2 -c1024m -t8 - -o -v $$arcdatafile$$.tmp -o $$arcpackedfile$$.tmp
unpackcmd = pzlib d -t8 - -o - <stdin> <stdout>

PLEASE HELP sorry for my english :D

srep64+pzlib:m3f:a64:d1g+nz :(

srep64+pzlib+nz :D

For AC unity their is no need for any pre-compressor
so basically use this
srep64+xz
or
srep64+nz
or
srep64+zcm

We are in the forum of madness answered once and once again the same question.

@ChronoCross you have to pay some attention for them 'cause someday maybe one of them will be a pro in this field

srep64+pzlib+nz :D

dear aswad. You need to pay attention zlib precompressors goes always first. Also if the compressed file have a few kb the file are corrupted. Is easy and very obvious.

Dear ChronoCross , do i look like a guy who don't know where should i put the pre-compressor :D I rewrite the method to fix only the parameters :D also everyone knows that pre-compressors comes in the first place so no need to tell anyone that .. he is free to use it in the first or middle or even in the end :)

ChronoCross 17-11-2016 07:15

Yeah, but we need to post the right answer or the correct way for compress files to get small size. Hey ezzeldin16 did you know flac compressor is better than tak and tta for compress wav audio files. Now you learn something. ;)

Gupta 17-11-2016 07:26

if u get ogg into the scene then the compression is even better

ChronoCross 17-11-2016 11:26

If we are talk about tta tak and flac this compressors are lossless. ogg is lossy you can't go back to the original file.

but the loss in the quality can't be sense

Not true always, use delta before reflate u will get better speed with little bit decrease in compression
