Bodycam "Failed to fill whole buffer" error #45

Closed PineconeCipher closed 3 weeks ago

PineconeCipher commented 1 month ago

Forgive me as I am incredibly green at parsing any sort of file. So I ran this...

uesave to-json -i D:\uesave\dump\PlayerInfo.sav Found non-standard magic: [ff, fe, 47, 00] (��G ) expected: GVAS, continuing to parse... Error: at offset 3130: io error: failed to fill whole buffer

After skimming thru other issues, it seems this .sav is encrypted. Just curious is there is any shot at just getting it over to a .json. The other problem that could be an issue is, this was made by a French dev team, so they could have encoded the file in French? (OEM 683:French)?

I converted it to HEX but there's nothing that pops out to me, again, pretty green at this. I'll drop the file as there is some english near the end.

Any help much appreciated!

EDIT: Attaching another .sav that has much more data to pull from. Going to try a few things.

  1. PlayerInfo.zip

  2. PlayerSkin.zip

Both of those saves parse perfectly for me. The header in your error message is showing different bytes than the headers in the files you uploaded. Are you somehow trying to open a different file?

Hex dump of the intact header for reference:

00000000  47 56 41 53 03 00 00 00  0a 02 00 00 f1 03 00 00  |GVAS............|

huh, interesting... I could have somehow "corrupted" the data. I accidentally opened it with notepad++ (idiot me) and had autosave on. I'll launch the game so it creates a new sav file and try again.

This time not at 4am either lol.

Thanks!!
