Future-proof NvENC & NvFBC patcher

• Working internet connection during configuration (i.e cloning does NOT include dependencies)
• CMake
• C++ compiler

git clone 'https://github.com/illnyang/nvlax.git'
cd nvlax
mkdir build && cd build
cmake ..
make

Protip: use WSL if you're using Windows.

Linux:
# nvlax_encode -i /usr/lib/libnvidia-encode.so.495.44 -o /usr/lib/libnvidia-encode.so.495.44
Windows:
# nvlax_encode -i nvEncodeAPI64.dll -o nvEncodeAPI64.dll
# nvlax_encode -i nvEncodeAPI.dll -o nvEncodeAPI.dll

Linux:
# nvlax_fbc -i /usr/lib/libnvidia-fbc.so.495.44 -o /usr/lib/libnvidia-fbc.so.495.44

This patcher performs assembly-level heuristics instead of naive pattern-matching. The patching itself works more/less the same way as in keylase/nvidia-patch.

I have tested this patcher against the following versions (on Linux):

• 470.74
• 495.29.05
• 495.44

It should work on previous versions as well. Please don't open-up new issues if you're using ancient drivers, thanks.

nvlax_encode accepts NVIDIA DLLs as input files. NvFBC patching is not supported yet, though.

keylase/nvidia-patch - this project wouldn't exist if it wasn't for their outstanding reverse-engineering efforts. thanks!
