UX polish batch 1 (clients/windows/ui-polish-plan.md, workstreams W0/A1/B/C/E):
- W0: the shell's duplicated trust/settings structs are gone — src/trust.rs
re-exports pf-client-core's, so the shell and the spawned session binary share
ONE Settings shape over client-windows-settings.json. Fixes real bugs: the
shell's saves no longer drop session-side fields; the stats-overlay toggle
(show_hud -> show_stats, serde alias migrates old files) and the forwarded-
controller pick now actually reach the spawned session. The "Streaming engine"
Settings combo is gone (PUNKTFUNK_BUILTIN_STREAM=1 stays as the dev A/B knob).
- Forwarded-controller pinning by stable key (vid:pid:name, pf-client-core's
format): persisted as forward_pad, applied by the shell's own service at
startup AND by the session binary in session_params (both OSes — the session
never applied the pin before).
- A1 single window: the shell hides itself when the spawned session window
presents its first frame ({"ready":true}) and restores + foregrounds on the
child's exit — exactly one visible Punktfunk window at any time. Restore runs
before the request-access cancel gate so a Ready/Cancel race can't strand the
shell hidden.
- C console UI: punktfunk-session --browse gains --json-status (ready when the
library window presents; error line on a failed start), and the shell
surfaces it — "Open console UI" on paired hosts' menus, plus a controller-
detected hint card targeting the most recent paired host (x64 only; aarch64
ships no skia ui feature). Browse spawns hide/restore the shell like streams.
- B responsive: minimum window size (420x360); the hosts header collapses to
icon-only buttons below 700 px; the session status card shrinks instead of
clipping (max_width); busy pages, help actions, licenses and long labels wrap.
- E polish: session exe gets the app icon (winresource + WM_SETICON via the new
pf-presenter win32.rs); both exes share an explicit AppUserModelID on
unpackaged runs (packaged identity wins) so the windows group as one taskbar
app across the visibility handoff; "Start streams fullscreen" toggle passes
--fullscreen (GTK parity); connects stamp KnownHost::last_used; the connect
target is stashed for every route so "Connecting to X" always names the host.

punktfunk — Windows client
The native Windows app for streaming a punktfunk host to your PC. A modern WinUI 3 app that discovers hosts on your network, pairs with a PIN, and streams at your display's own resolution and refresh rate — with a hardware-accelerated D3D11 video path and HDR.
It's pure Rust: the UI is WinUI 3 driven through windows-reactor
(a declarative, React-like framework), and it links the shared punktfunk-core directly to speak
the fast punktfunk/1 protocol.
Features
- Hardware decode, GPU present — FFmpeg HEVC with a D3D11VA zero-copy path (decoder and
presenter share one D3D11 device; NV12/P010 textures sampled straight into a
SwapChainPanelcomposition swapchain), with a robust software-decode fallback. - HDR10 — advertise 10-bit/HDR, detect PQ in-band, and flip the swapchain to
R10G10B10A2+ ST.2084 with HDR10 metadata. - Your display's native mode — the host builds a virtual display at exactly your WxH@Hz.
- Audio both ways — WASAPI render + mic capture.
- Full controller support — SDL3 gamepads with rumble, lightbar, and DualSense feedback.
- Your display's native mode, really — "Native display" resolves the actual size + refresh of the monitor the window is on at connect time.
- Find hosts automatically — mDNS discovery lists hosts on your LAN, alongside saved and manual entries. First connect does a one-time SPAKE2 PIN pairing (or TOFU on trusted LANs), then reconnects on a pinned identity. Saved hosts carry per-host actions: a network speed test (probe burst over the real data plane → recommended bitrate, applied in one tap) and forget.
- Polished shell — host cards, settings (resolution / refresh / host compositor / decoder / codec / bitrate / HDR / forwarded controller / gamepad type / system shortcuts / audio channels / mic), a status-chip stream HUD, and the full trust surface. Stream input uses Win32 low-level hooks with Moonlight-style capture: Ctrl+Alt+Shift+Q releases the pointer, a click on the stream re-captures it, and system shortcuts (Alt+Tab, Win, …) can act locally or forward to the host.
Builds and ships for both x64 and ARM64 as a signed MSIX.
Get it
Install the signed MSIX from the package registry — see docs.punktfunk.unom.io/docs/install-client. A stock Moonlight client also works over GameStream if you prefer.
Build from source
Windows-only (the crate builds as a stub on other platforms so the workspace stays green). You need
the MSVC toolchain, an FFMPEG_DIR FFmpeg tree, and CMake (SDL3 builds from source). windows-reactor's
build.rs downloads the Windows App SDK NuGets and needs CARGO_WORKSPACE_DIR set.
cargo build -p punktfunk-client-windows --target x86_64-pc-windows-msvc
# CLI paths for testing (no window):
punktfunk-client --discover # list hosts on the LAN
punktfunk-client --headless --connect host[:port] [--pin HEX] # connect, count frames, print stats
punktfunk-client --headless --speed-test --connect host[:port] # probe burst → recommended bitrate
CARGO_HOMEmust be an ASCII path — non-ASCII characters break SDL3's MSVC precompiled-header build. Packaging (MSIX manifest, signing) lives inpackaging/.
