Adds a client-selectable **preferred codec** and wires the core + ABI + probe + Linux client to
negotiate and decode it. (Windows/Apple/Android follow in 2b.)
**Core:**
- `Hello.preferred_codec` (a single CODEC_* bit, 0 = auto) — a soft hint appended after
`video_codecs`. `resolve_codec(client, host, preferred)` now honors the preference when the host
can also emit it, else falls back to precedence (HEVC > AV1 > H.264). Roundtrip + preference tests.
- `NativeClient::connect` takes `video_codecs` + `preferred_codec`; `NativeClient.codec` exposes the
resolved `Welcome.codec`.
- ABI: `punktfunk_connect_ex7` (adds the two codec params; `ex6` delegates to it advertising
HEVC-only) + `punktfunk_connection_codec` getter + `PUNKTFUNK_CODEC_{H264,HEVC,AV1}` constants
(drift-guarded against the wire values). Header regenerated.
**Host:** passes `hello.preferred_codec` into `resolve_codec`.
**probe:** `--codec h264|hevc|av1|auto` sets the preference (still advertises it can decode all
three); the dump extension already follows the resolved codec.
**Linux client:** advertises the codecs FFmpeg can actually decode (`decodable_codecs()`), threads
the user's `codec` setting as the preference, and builds the decoder — both the software and VAAPI
paths, plus the mid-session VAAPI→software demotion — from the negotiated `Welcome.codec` instead of
hardcoding HEVC. New "Video codec" dropdown in Preferences (Automatic/HEVC/H.264/AV1).
Live-validated on the dev box: probe `--codec hevc` against a software (H.264-only) host resolves to
H.264 (graceful soft-preference fallback), no failure. clippy + core (57) + host (133) tests green.

# 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
|
|
powershell -ExecutionPolicy Bypass -File scripts\windows\setup-build-env.ps1
|
|
```
|
|
|
|
Persists (Machine scope) the three vars the NVENC build needs:
|
|
|
|
| var | value | why |
|
|
| --- | --- | --- |
|
|
| `PUNKTFUNK_NVENC_LIB_DIR` | `C:\Users\Public\nvenc` | NVENC import lib (`nvencodeapi.lib`) |
|
|
| `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
|
|
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 `:3000`, opens inbound TCP 3000, 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>:3000`
|
|
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
|
|
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.
|
|
|
|
## Typical flow after pulling new code
|
|
|
|
```powershell
|
|
git pull
|
|
powershell -ExecutionPolicy Bypass -File scripts\windows\deploy-host.ps1
|
|
powershell -ExecutionPolicy Bypass -File scripts\windows\build-web.ps1
|
|
```
