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>
Windows host build/deploy scripts
Helper scripts for the Windows host box (the RTX .173 lab box, repo at
C:\Users\Public\punktfunk-native). Run them from the repo root in an elevated PowerShell.
One-time: persist the build environment
powershell -ExecutionPolicy Bypass -File scripts\windows\setup-build-env.ps1
Persists (Machine scope) the vars the host build needs (NVENC itself needs none — its entry
points are runtime-loaded from the driver's nvEncodeAPI64.dll):
| var | value | why |
|---|---|---|
LIBCLANG_PATH |
C:\Program Files\LLVM\bin |
bindgen (libclang.dll) |
CMAKE_POLICY_VERSION_MINIMUM |
3.5 |
audiopus_sys / cmake crates |
FFMPEG_DIR is not set — the --features nvenc build the RTX box uses does not link
libavcodec (that is only the amf-qsv feature). The VS C++ toolchain is loaded per-build via
vcvars64.bat (auto-discovered with vswhere).
Rebuild + redeploy the host service
powershell -ExecutionPolicy Bypass -File scripts\windows\deploy-host.ps1
Stops PunktfunkHost, backs up the current binary (punktfunk-host.exe.bak), builds
--release -p punktfunk-host --features nvenc from the current source, then restarts the
service on the new binary — with automatic rollback if the build fails or the new binary
won't start. The service is down only for the build duration.
Web management console
On an installed host (the setup.exe) the console is set up automatically — no manual steps.
The installer bundles the built (self-contained, no-node_modules) .output server + a portable
bun and runs punktfunk-host.exe web setup, which registers the PunktfunkWeb scheduled task
(at boot, as SYSTEM, restart-on-failure) running {app}\web\web-run.cmd →
bun …\.output\server\index.mjs on :47992, opens inbound TCP 47992, and writes the login password to
%ProgramData%\punktfunk\web-password (ACL'd to Administrators + SYSTEM). The mgmt bearer token it
proxies with is the host's own %ProgramData%\punktfunk\mgmt-token. Browse http://<host-ip>:47992
and log in with the password the installer shows on its final page. To change it, edit
web-password and re-run the task: schtasks /run /tn PunktfunkWeb.
Rebuild + restart the console (dev box)
powershell -ExecutionPolicy Bypass -File scripts\windows\build-web.ps1
bun install && bun run build (Nitro noExternals -> a self-contained .output, no
node_modules/.npmrc), then restarts the PunktfunkWeb task and checks :3000/login. Use
this to iterate on the console against an installed host - punktfunk-host.exe web setup (or a
fresh install) is what creates the task in the first place.
