oo2reck can't decompress all oodle streams.
I think you find oodle streams by 0xF flag after decryption.
In Fifa 19 0x11 is oodle stream too.
Take a look at output file and you'll see lots of oodle streams are still not decompressed.
If oo2reck decompresses them you'll get even better results.
example : 00040000917055C2
compflag = 0x91 ==> that is oodle too.
(if oo2reck not using scanner)

i know , the thing here is that the oodle precompressor doesn't use those headers so it does happen that it misses a few

in any case to show that i know, if you check cdt, it does decrypt all those streams meaning it does see them just that oo2reck wasn't informed about the headers because it doesn't look for cas headers, the 0x91 you mention but instead it searches for kraken stream headers which start with 0x86

I think kraken stream headers start with 0x8C.
yes cdt does its work perfectly and you are right , this is a generic oodle precompressor.
But if you make it work specifically for Fifa 19 by cas headers, result could be amazing.
by the way encrypting data back is not needed.Game reads decrypted data.(IF header is fixed )
