The Windows host was NVIDIA-only (NVENC) with an openh264 software fallback. Add
AMD AMF and Intel QSV via libavcodec — the Windows analogue of the Linux VAAPI
backend — so one installer serves all three GPU vendors.
- encode/ffmpeg_win.rs: new WinVendor{Amf,Qsv} encoder. System-memory NV12/P010
readback (default, robust) + opt-in zero-copy D3D11 (PUNKTFUNK_ZEROCOPY: shares
the capturer's ID3D11Device; AMF takes AV_PIX_FMT_D3D11, QSV derives a QSV frames
ctx and maps) with a system fallback for the format-group mismatch the capturer's
video-processor fallback can produce. HDR Main10 (P010 + BT.2020/PQ VUI; an
Rgb10a2->P010 swscale covers the shader fallback).
- encode.rs: Codec::amf_name/qsv_name; open_video + windows_resolved_backend()
resolve PUNKTFUNK_ENCODER=auto|nvenc|amf|qsv|sw via a DXGI adapter VendorId probe.
- capture/dxgi.rs: gpu_mode mirrors the resolved backend (D3D11 NV12/P010 for AMF/QSV).
- gamestream/serverinfo.rs: GPU-aware codec advertisement (windows_codec_support;
AV1 gated to RDNA3+/Arc, like the VAAPI path).
- Cargo.toml: amf-qsv feature (optional ffmpeg-next in the windows target block).
- CI/installer: windows-host.yml sets FFMPEG_DIR + builds --features nvenc,amf-qsv;
the Inno installer bundles the FFmpeg DLLs; host.env default nvenc -> auto.
CI-green target; AMF/QSV not yet on-glass validated (no AMD/Intel Windows box in the
lab) — NVENC stays live-validated. An adversarial-review pass caught + fixed real
FFI bugs (AV_PIX_FMT_P010 is a macro -> P010LE; windows-rs 0.62 GetImmediateContext/
GetDesc1 return Result; AV_HWFRAME_MAP_* is a bindgen enum with no BitOr).

The smoke-test diagnostic proved Inno itself is healthy (a trivial ASCII script
compiled), while the real .iss died before the "Compiler engine version" line —
i.e. at script open, not during compile. The difference: the real .iss was UTF-8
with non-ASCII chars (→, —) in comments, which ISCC 6.4+ rejects without a UTF-8
BOM (and the German-locale runner misreads). Replace them with ASCII (->, -).

All [Files] sources are validated-present yet ISCC still errors before any
"Compiling" output (no line number) — so it's startup/[Setup]-internal, not a
source path. Add an explicit [Languages] (compiler:Default.isl) to rule out the
auto-added default language, and on ISCC failure dump the Inno install dir +
run a trivial [Setup]-only smoke script to tell "Inno broken" from "my script".

The {#SourcePath} relative-traversal for host.env.example/README kept tripping
ISCC ("path not found", error 2) regardless of the separator, so drop it: compute
the two paths absolutely in pack-host-installer.ps1, Test-Path them (clear PS error
if missing), and pass /DHostEnv + /DReadme. The .iss [Files] now reference the
absolute defines — no {#SourcePath}, no ..\.. traversal. Also prints "source ok"
for each so a future failure is unambiguous.

ISPP's {#SourcePath} has no trailing backslash, so {#SourcePath}..\..\scripts
resolved to ...\packaging\windows..\..\scripts (invalid component "windows..")
-> ISCC error 2 "path not found". Add the explicit separator (a double backslash
is harmless on Windows if a future ISPP ever adds the trailing one).

MSIX (the client's format) can't install the host's LocalSystem secure-desktop
service or the SudoVDA kernel driver, so the host ships as a signed Inno Setup
setup.exe that runs elevated and delegates to the existing idempotent
`punktfunk-host service install`.
- packaging/windows/punktfunk-host.iss: lay exe into Program Files, optional
SudoVDA driver task, run service install/start; [Code] stops+waits the service
before file copy on upgrade; uninstall runs service uninstall.
- pack-host-installer.ps1: cert (reuses MSIX_CERT_PFX_B64 / self-signed CN=unom),
sign inner exe + setup.exe, fetch/stage SudoVDA, run ISCC, export public .cer.
- fetch-sudovda.ps1 / install-sudovda.ps1: pinned SudoVDA + nefcon download, cert
import, gated device-node create (no phantom dup), pnputil install (warn-not-abort).
- nvenc/: synthesize nvencodeapi.lib via llvm-dlltool from a 2-export .def so
--features nvenc links with no GPU/SDK at build time.
- .gitea/workflows/windows-host.yml: build (nvenc) -> clippy -> ISCC -> sign ->
publish setup.exe + .cer to the generic registry pkg punktfunk-host-windows.
Tag host-win-v* -> X.Y.Z (+ latest/ alias); main push -> rolling 0.2.<run>.
- setup-windows-runner.ps1: provision Inno Setup; docs: installer instructions.
SudoVDA/nefcon release URLs+SHA-256s in fetch-sudovda.ps1 are placeholders
(baseline v0.2.1) — fetch warns + prints the computed hash until pinned.
