Cls bcm & zlib

[78372]

1. BCM

BCM STDIO Patch updated for bcm140_win64. Supports stdio in both compression and decompression now and can be multithreaded with PMT. CLS is not required anymore.
PMT Example Settings:

[bcm]
Encode = bcm -1 stdin stdout <stdin> <stdout>
Decode = bcm -d stdin stdout <stdin> <stdout>

2. ZLIB
Uses default compression level. Doesn't need external executables.

does the cls-zlib support UA/diskspan if i extract it to my compressors folder in the tools bundle package kaktor uploaded in his post on the CIUv3 thread? im new so im not sure how to use this new zlib cls with UltraArc/diskspan.

please post back and tell me if it is compatible and if so, what i need to do to make diskspan/ua use it. im not that good with freearc so im not sure how to go about adding it to freearc. thanks for any advice.

*note* also, can this be used as with xtool.exe or is it only usable with freearc standalone .exe?

You can use it with DiskSpan and FreeArc. These two things are compresssors, I.E alternative of lzma/lolz. It has nothing to do with xtool.

thanks for answering my post. my next question is, i unpacked both the cls-bcm and cls-zlib archives and put cls-zlib in the cls-bcm folder. once thats done, i put cls-zlib and bcm together in the same folder with the bcm .exe and related files. also, what file types exactly does bcm compress? i've heard of ecm which was used mostly for compressing ps1 isos but i've never heard of bcm. does it have something to do with compressing .bin files?

^^

update: nevermind, i see how it works. i copied the extracted files from cls-bcm and cls-zlib to my freearc/bin folder and now it works. all i do is put the files i want to compress in the pack folder and run the compress.bat batch script to compress them and put the bin file i want to unpack in 'unpacked' folder.

Is any way to make BCM multithreaded ?

Try using 4x4.
Like 4x4:chunksize:tthread:bcm
Ex: srep:m3f+4x4:b64m:t4:bcm

The "CLS.BCM.dll" file is missing!?

And nobody noticed that yet.
File uploaded, check it now.

Thanks 78372

Thank you very much !
Compression works well with 4x4,but decompression... No...
Single threaded BCM is fine ,but 4x4'd ,NO !
bcm130_win64.zip was used for compression.

Can you help me how to decompress 4x4:chunksize:tthread:bcm ?

The error :

arc t e:\xxx.arc

Files from cls_bcm.7z are near arc.exe in separate unpack folder :
bcm.exe
bcmpatch.dll
cls-bcm.dll

arc.ini in unpack folder doesnt contain BCM section.

Expected behavior. Stdio support in bcm is not so stable and compression doesn't support stdio. 4x4 messes up with streams in this type of case.

Ok,thanks.
but if i make an archive with -mbcm ,how can i decompress it multithreaded wihtout tmp file ?

[78372]

Umm, not possible atm I think

Hi 78372
bsc is better than bcm, please add support stdio if possible.
