get-priv-data

Retrieve NvFBC Private Data (UUID) from a Steam installation

Method for finding the UUID constant

The C code might look something like this

NvFBCCreateParams createParams;
memset(&createParams, 0, sizeof(createParams));
...
createParams.pPrivateData = (void*)enableKey;
createParams.dwPrivateDataSize = 16;

So we want to find an assignment (MOV dword ptr) to an offset (ptr) in .rdata

followed by an assignment (MOV dword ptr) of value 16 (10h)

Usage

There are releases precompiled for you! You can find them in the Releases tab
