Masked Compression (Ultimate compression in one go)

[felice2011]

Hey panker i''m trying to test your new method all in one, so you called, with different titles small, to speed up the test, but it seems impossible not to have managed to compress a title, with each change of line gives me an error different: error in precomp, error in LZ77, the last error "disk full in delta compression algorithm"



I think you have to redefine your new method so that it fits in most of the data files.
I also noticed that most different algorithms are added to the mask, it is more subject to error.

P.S the same titles that are not able to test with your method, I have successfully compressed using the common methods known "-mmsc+precomp+srep64+xz", "-mmsc+srep64+zstd" or "-mreflate+precomp+srep+delta+lzma".

I hope for a solution..

all in all i havent told you how it works and how to chain a compressor with another compressor

This is the method i have used most of the time

-mmsc+srep64+rep:512+delta+exe+xz/$jpgsolid=jpg+zstd/$void=srep64+zstd/$text=srep64+zpaq

the method i provided is absolutely made with 16 gigs of ram in mind
personally i got 12 gigs, running many compressos all at once does an impact on cpu too

i am posting a photo to show you my results, as well as i try to optimize it for lower spec PCs

From personal exp. i have found that 4G ram PCs will never make it and produces many errors
also zstd.exe, 7z.exe and many others are 64 bit only so

Check Method in photo for Masks
and see the results

This is the file for compression:



This is error in cmd:



I also tried to compress GTA San Andreas with the same error.
I really like the method and I'm sorry for those errors. However, I have 8 gb ram and I amended the parameters in arc.ini. Without trying precomp all goes well until the end.
