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>
