i was wrong. i mean that part of history:

-m2 -lN now is the same as -m3 -lN -cN: compression ratio is average between -m1 and -m3, while speed is the same as in old versions

so you can improve -m2 -lN method in srep 2.0 by using -m3 -lN -cN instead

Hi guys, i'm testing xz 5.2.1 and i'm having a hard time in making it work with freearc. I'm using these parameters:

[External compressor:xz]
packcmd   = xz.exe -9 -v -c <stdin> <stdout>
unpackcmd = xz.exe -d -c <stdin> <stdout>

It achieves 99~100% but at the end shows this error:

ERROR: general (de)compression error in xz

Any clues?

Usage: xz [OPTION]... [FILE]...
Compress or decompress FILEs in the .xz format.

Mandatory arguments to long options are mandatory for short options too.

 Operation mode:

  -z, --compress      force compression
  -d, --decompress    force decompression
  -t, --test          test compressed file integrity
  -l, --list          list information about .xz files

 Operation modifiers:

  -k, --keep          keep (don't delete) input files
  -f, --force         force overwrite of output file and (de)compress links
  -c, --stdout        write to standard output and don't delete input files
      --single-stream decompress only the first stream, and silently
                      ignore possible remaining input data
      --no-sparse     do not create sparse files when decompressing
  -S, --suffix=.SUF   use the suffix `.SUF' on compressed files
      --files[=FILE]  read filenames to process from FILE; if FILE is
                      omitted, filenames are read from the standard input;
                      filenames must be terminated with the newline character

      --files0[=FILE] like --files but use the null character as terminator

 Basic file format and compression options:

  -F, --format=FMT    file format to encode or decode; possible values are
                      `auto' (default), `xz', `lzma', and `raw'
  -C, --check=CHECK   integrity check type: `none' (use with caution),
                      `crc32', `crc64' (default), or `sha256'
      --ignore-check  don't verify the integrity check when decompressing
  -0 ... -9           compression preset; default is 6; take compressor *and*
                      decompressor memory usage into account before using 7-9!
  -e, --extreme       try to improve compression ratio by using more CPU time;
                      does not affect decompressor memory requirements
  -T, --threads=NUM   use at most NUM threads; the default is 1; set to 0
                      to use as many threads as there are processor cores
      --block-size=SIZE
                      start a new .xz block after every SIZE bytes of input;
                      use this to set the block size for threaded compression
      --block-list=SIZES
                      start a new .xz block after the given comma-separated
                      intervals of uncompressed data
      --flush-timeout=TIMEOUT
                      when compressing, if more than TIMEOUT milliseconds has
                      passed since the previous flush and reading more input
                      would block, all pending data is flushed out
      --memlimit-compress=LIMIT
      --memlimit-decompress=LIMIT
  -M, --memlimit=LIMIT
                      set memory usage limit for compression, decompression,
                      or both; LIMIT is in bytes, % of RAM, or 0 for defaults
      --no-adjust     if compression settings exceed the memory usage limit,
                      give an error instead of adjusting the settings downwards

 Custom filter chain for compression (alternative for using presets):

  --lzma1[=OPTS]      LZMA1 or LZMA2; OPTS is a comma-separated list of zero or
  --lzma2[=OPTS]      more of the following options (valid values; default):
                        preset=PRE reset options to a preset (0-9[e])
                        dict=NUM   dictionary size (4KiB - 1536MiB; 8MiB)
                        lc=NUM     number of literal context bits (0-4; 3)
                        lp=NUM     number of literal position bits (0-4; 0)
                        pb=NUM     number of position bits (0-4; 2)
                        mode=MODE  compression mode (fast, normal; normal)
                        nice=NUM   nice length of a match (2-273; 64)
                        mf=NAME    match finder (hc3, hc4, bt2, bt3, bt4; bt4)
                        depth=NUM  maximum search depth; 0=automatic (default)

  --x86[=OPTS]        x86 BCJ filter (32-bit and 64-bit)
  --powerpc[=OPTS]    PowerPC BCJ filter (big endian only)
  --ia64[=OPTS]       IA-64 (Itanium) BCJ filter
  --arm[=OPTS]        ARM BCJ filter (little endian only)
  --armthumb[=OPTS]   ARM-Thumb BCJ filter (little endian only)
  --sparc[=OPTS]      SPARC BCJ filter
                      Valid OPTS for all BCJ filters:
                        start=NUM  start offset for conversions (default=0)

  --delta[=OPTS]      Delta filter; valid OPTS (valid values; default):
                        dist=NUM   distance between bytes being subtracted
                                   from each other (1-256; 1)

 Other options:

  -q, --quiet         suppress warnings; specify twice to suppress errors too
  -v, --verbose       be verbose; specify twice for even more verbose
  -Q, --no-warn       make warnings not affect the exit status
      --robot         use machine-parsable messages (useful for scripts)

      --info-memory   display the total amount of RAM and the currently active
                      memory usage limits, and exit
  -h, --help          display the short help (lists only the basic options)
  -H, --long-help     display this long help and exit
  -V, --version       display the version number and exit

With no FILE, or when FILE is -, read standard input.

[External compressor:xz]
packcmd   = xz -z -9 -T0 -M0 -v $$arcdatafile$$.tmp
unpackcmd = xz -d -v $$arcdatafile$$.tmp.xz
packedfile = $$arcdatafile$$.tmp.xz

Thanks felice2011 it's working fine now. It's a shame stdio doesn't work properly.

the reason why xz cant be used with stdio capabilities are various, but i can show you how to use xz with 7z support it supports stdin and stdout and its streaming works wonderfully

[External compressor:xz,lzma2]
header = 0
packcmd = 7z a -txz -an -m0=lzma2{:option}:fb=273:mf=bt4:mc=100000000:lc=4: lp=0 -mx9 -si -so <stdin> <stdout>
unpackcmd = 7z x -txz -an -y -si -so <stdin> <stdout>

use it like this

srep:m3f:a1+lzma2:d256m:c1024m:mt4
or
srep:m3f:a1+xz:d256m:c1024m:mt4

d(dictionary)m
c(chunk)m
mt4 = 4 threads

this combo does need ram so careful

enjoy a wonderful streaming experience both in comp and decomp (decomp is now multithreaded)

I extract game using quick bms and done. Then How to packing again the file after extracted?

[Andu21]

Is there any gain in ratio by using different srep versions? Let's say by using 3.92 instead of the latest 3.93 beta?

Hello Guyz its About Razors Original Script, I really appericiate that guy

so i am here because i am still a noob & don't try to laugh at me

Basically i want to add Music Button, About Button, Fonts, Video Trailer(Optional)

Don't tell me use modded versions because they are messed up with lots of bugs and i also don't want to messup with razors code, Help me please it will be appreciated.

Thanks

[rinaldo]

PsYcHo_RaGE

Music Button, About Button, Fonts, Video Trailer(Optional)

too many things together and can be done in 100 different ways (paradoxical but true)

Don't tell me use modded versions because they are messed up with lots of bugs

then you'll have to learn the code yourself or adapt an existing one around the forum (I'll tell you that razor will make you a customized version)


Example =>

Can You Help Me, Okay i want to add music & About button only now so i can understand how to edit the script in a right manner.

Please if you are going to gimme a new script, gimme razors original script but with music button & about button working and nothing much more

and as you said about me, i am still learning and still a noob

[rinaldo]

I gave you an example so that you can understand, without all that code that can distort you from your goal, I do not think you'll find better solution in the forum

I appericiate your help brother but if you can gimme that razors original script without changing anything other than music & about button

[Andu21]

Thanks. i'll give it a try, this is esentially creating a xz archive through 7-Zip right?

Why not use radyx instead?

i haven't tried radyx myself but its author said to achieve the ratio you get on xz/7z you need double the ram so...... radyx gives speed not good ratio unless you have a ram hungry machine

[Andu21]

Alright i thought it was the other way around due to some improvements from zstd, less memory and same ratio.
