OGG_File_Checker
Some small batch I wrote some weeks ago.

Checks OGG files (OggS vorbis) for which OGGRE by Profragger has problems. 

MESA from Shegorat is not included because it is krinkels exclusive. 
If you have access to it, place mesa-x64.exe in OGG_File_Checker folder.

If you don't have access to MESA, copy loose OGG files inside Input folder.

Run OGG_File_Checker.bat and wait for finish.

Example: Kingdome Come Deliverance 2, Music.pak
There are a total of 2816 OggS vorbis streams. 40 of them will cause OGGRE to crash or stuck in an infinite loop on decompression.

These bad files will be stored in a text file (Bad_Files.txt) and will be copied to _Bad_Files folder additionaly.

Additionaly this tool will create patch files (stored in Patch_Files folder) if you want to patch the bad files back to original files afterwards. You can choose between hdiffz or xdelta patch engine.


Checksum hashing is a bit slow especially if you have over 10k files (it will take a while). I didn't found a tool by now which works faster than xxhsum.

Thanks to César for a little help with checksum checking.

Hello
Sometimes, conversion is weird...
I used cls-ue4d v.25.07.03.rev.1 on Sifu (last version)

I know it works pretty well because I uncrypted .pak and remove some data in stream.
With an hex editor i can see that the files is fully uncrypted.
(I can compare extracted files with quickbms, exactly the same in the uncrypted file)

With ued4t 99% uncrypted, with unreal xtool plugin around 98%
If I work on file to compare extracted files there is some diff
This makes tools like xtool missing some stream

By the way the think I do not understand, is with partial uncrypt like with unreal plugin, the final compress ratio is better

like for my tests :
cls-ue4d+srep+lolz => 12gb
xtool:mue4+srep+lolz => 10gb
ue4dt+srep+lolz= 9.96gb
