Worked on stabilizing OBS Studio NVENC builds in the Saghen/nixpkgs repository, focusing on system packaging and build systems using Nix. Addressed a recurring build failure by implementing conditional runpath handling for CUDA-enabled configurations, ensuring that the correct driver paths are resolved at runtime. This solution involved adding autoAddDriverRunpath only when CUDA support is enabled, which prevents NVENC-related build issues and improves the reliability of downstream OBS Studio artifacts. The fix was consolidated into a single, clear commit, streamlining future troubleshooting and reducing investigation time for similar failures in continuous integration environments and production deployments.
