get-priv-data-gfe

Retrieve NvFBC Private Data (UUID) from a GeForce Experience installation

Method for finding the UUID constant

The C code might look something like this

NvFBCCreateParams createParams;
memset(&createParams, 0, sizeof(createParams));

((&createParams.pPrivateData) + 0x0) = 0x00000000;
((&createParams.pPrivateData) + 0x4) = 0x00000000;
((&createParams.pPrivateData) + 0x8) = 0x00000000;
((&createParams.pPrivateData) + 0x10) = 0x00000000;

createParams.dwPrivateDataSize = 16;

So we want to find an assignment (MOV dword ptr) of value 16 (10h)

proceeded by 4x evenly spaced 4 byte assignments.
