enricobuehler	a58b6b8e76	fix(windows-client): clear clippy -D warnings on MSVC ... The cfg(windows) code can't be lint-checked on the Linux dev box, so three -D warnings slipped through (caught by windows.yml; the FFI + shaders compiled fine): - gpu.rs: SetMultithreadProtected returns a must-use BOOL -> `let _ =`. - video.rs: drop the unused GpuFrame::ten_bit field (present keys off `hdr`; the value is still computed locally for the first-frame log). - present.rs: GpuView::frame is an RAII keep-alive (its Drop returns the decoder surface to the pool), never read -> #[allow(dead_code)].

enricobuehler	0cc36fa130	feat(windows-client): D3D11VA zero-copy hw decode + HDR10 present + GUI polish ... The client was pure software HEVC decode + CPU swscale->RGBA + a full-frame dynamic-texture upload every frame -- the reason performance was poor on a GPU box (the GPU sat idle while the CPU churned). This adds a hardware path, HDR, and a GUI pass. Performance -- D3D11VA zero-copy: - gpu.rs (new): one D3D11 device (hardware + VIDEO_SUPPORT, WARP fallback, multithread-protected) shared by decoder and presenter via a Send/Sync OnceLock. Sharing is mandatory -- a decoded texture is only bindable on the device that created it. windows-rs COM interfaces are !Send/!Sync, so the unsafe impl is sound only under the multithread protection + disjoint decode(video ctx)/present(immediate ctx) split. - video.rs: D3d11vaDecoder (raw FFI mirroring the Linux VAAPI module). The COM-typed AVD3D11VA{Device,Frames}Context are declared here (stable FFmpeg ABI) to avoid ffmpeg-sys binding the d3d11 headers; get_format builds a frames ctx with BindFlags=SHADER_RESOURCE so the NV12/P010 array slices are sampleable. av_frame_clone guard keeps each surface out of the reuse pool until the presenter drops it. Software decode stays as the fallback (DecoderPref Auto/Hardware/Software; auto falls back on init/decode error). - present.rs: shared device; per-plane SRVs over the array slice (NV12->R8/R8G8, P010->R16/R16G16) + three pixel shaders (RGBA passthrough, NV12/BT.709, P010/BT.2020-PQ). present() now takes the frame by value so the GPU surface survives re-presents. HDR: - Detected in-band (transfer == SMPTE2084), same signal as the other clients. Swapchain flips to R10G10B10A2 + ST.2084 + HDR10 metadata. New Settings toggle gates advertising VIDEO_CAP_10BIT|HDR; host still gates 10-bit behind its own PUNKTFUNK_10BIT + actual-HDR-content checks. GUI (windows-reactor): - Host cards with accent-monogram avatars + colored status pills, InfoBar for errors/pairing hints, ToggleSwitch settings (+ HDR, decoder, bitrate), button icons, a richer connecting screen, and a stream HUD with GPU/CPU-decode + HDR status chips. Not yet on-glass validated: the Linux dev box can't compile the cfg(windows) code (ffmpeg/windows crates unfetched; WARP has no hw decode) -- only cargo fmt checks it here. API shapes verified against the windows-rs/reactor source and the YUV->RGB coefficients checked by hand, but D3D11VA + shaders + the GUI need a real build (Windows CI / build VM) and on-glass test on the RTX box. The host-side HDR encode path is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-18 23:16:07 +00:00
