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>

Rebuild the punktfunk Windows host (release + NVENC) from the CURRENT source and
|
|
restart the LocalSystem service, with automatic rollback if the build fails or the
|
|
new binary won't start.
|
|
|
|
powershell -ExecutionPolicy Bypass -File scripts\windows\deploy-host.ps1
|
|
|
|
Prereqs: run setup-build-env.ps1 once (persists the build env), and VS C++ build tools
|
|
installed (vcvars64.bat is auto-discovered via vswhere). The service is stopped for the
|
|
duration of the build (the running .exe is locked), then restarted on the new binary.
