The nvenc build linked nvEncodeAPI64.dll's entry points at load time, so a --features nvenc binary hard-crashed on any box without the NVIDIA driver (AMD/Intel). Entry points now come from a runtime LoadLibrary table (encode/windows/nvenc.rs load_api); a missing DLL just falls through the encoder auto-detect to AMF/QSV/software. The generated import lib and all its plumbing (gen-nvenc-importlib.ps1, nvenc.def, PUNKTFUNK_NVENC_LIB_DIR, setup-build-env wiring) are gone. Live-validated on the RTX 4090 box (NVENC session, 7000+ frames). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Persist the punktfunk Windows-host build environment (Machine scope, run once, elevated).
|
|
|
|
After this, deploy-host.ps1 needs only the VS toolchain (it loads vcvars64.bat itself).
|
|
These are BUILD-time vars; runtime config lives in C:\ProgramData\punktfunk\host.env.
