Is it possible to use LZ4 with arc?

[danswano]

Hello,
Is it possible to use LZ4 with arc?
If yes can you provide me with the packcmd and unpackcmd for arc.ini?
Thank you.

[Nizar3003]

[External compressorlz4]
header = 0
packcmd = pLZ4 e -l9 -t4 - -o - <stdin> <stdout>
unpackcmd = pLZ4 d -t4 - -o - <stdin> <stdout>

Thanks but i didn't mean pLZ4 i meant the older LZ4.

[Razor12911]

yes, possible. -mlz4, you don't have to add anything.

[danswano]

I've tried that didn't work for me and it just skipped it and made the archive as storing only.

[Razor12911]

See?

You can use this one if it still doesn't work.

I'm trying to precompress "FlatOut 4 - Total Insanity" using either plz4 or lz4 but i'm unable to get the decompressed size that "Drop and Scan for LZ4" is giving me.
I'm using those parameters to precompress:
packcmd = pLZ4 e -l9 -t4 - -o - <stdin> <stdout>

Any idea why i'm getting a big decompressed size only in the scanner?
Thanks Razor.

Thanks Razor.

But are you really convinced of using pLZ4 with "* .PKG" files of FO4?

Could be false positives, tool is not perfect

You can check the repacks floating around, there is 2 already with size under 4 G.B which is impossible to achieve with srep+lzma.

Thank you.

[External compressor:lz4]
header = 0
packcmd    = lz4 -12 -B7 -BD - - <stdin> <stdout>
unpackcmd  = lz4 -d - - <stdin> <stdout>

Just answering what you asked. But you probably meant the pre-processor.

if you remove all the soundtracks folder and all the wallpaper junk thats not needed by the game you can get to dvd5 with srep+lzma .look at my data1.bin that the complete game and that will fit on dvd5.the second bin thats soundtrack and wallpapers(not needed)

@mikey26
some users managed to go near 3.5 g.b for the games files without the extras but it's something related to LZ4.

I did remove them but i didn't reach such good ratio as yours.
can you paste here your arc.ini and .bat content please.

FlatOut 4 uses LZ4 compression for game resources.

And Razor's public LZ4-precompressor is a very early build, not able to precompress most games I tried. And I doubt he will release an updated build in near future, if at all

Do you suggest an alternative to pre-compress LZ4 until a final build of pLZ4 see the light?
