The vendor-agnostic DXVA path for GPUs without Vulkan Video (Intel's Windows driver foremost, which previously landed on CPU decode). Ported from the retired WinUI presenter's decoder with its Intel-safe discipline intact (decode pool stays libavcodec-derived — a hand-built pool broke Intel at the first SubmitDecoderBuffers), on a decode device LUID-matched to the presenter's adapter. Hand-off is a ring of shareable BGRA8 textures (SHARED_NTHANDLE | SHARED_KEYEDMUTEX) filled by the fixed-function ID3D11VideoProcessor (NV12/P010 → BGRA8, colour spaces from the per-frame CICP; PQ is tone-mapped to SDR by the processor — HDR-first boxes take Vulkan Video). BGRA is deliberate: importing a multiplanar NV12 D3D11 texture device-losts on NVIDIA however it is consumed (plane-view sampling and DMA copy both validation-clean, both TDR — bisected), while single-plane RGBA D3D11↔Vulkan interop is the path Chromium/ANGLE exercise on every driver. The presenter imports a slot's NT handle per frame (VK_KHR_external_memory_win32, gated on the spec-required external-format probe) and blits it into the video image — no CSC pass; the DXGI keyed mutex (key 0 both sides, drop-tolerant) is the cross-API lock and visibility barrier. Verified live vs a real host at 5120x1440@240 HEVC on an RTX 4090: 240 fps, e2e 2.7/3.0 ms p50/p95 under the Khronos validation layer — parity with Vulkan Video (2.6 ms); auto still resolves vulkan on NVIDIA. PUNKTFUNK_DECODER=d3d11va forces it; import/present failures demote to software on the existing streak contract. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

//! Shared, UI-agnostic client plumbing, extracted verbatim from the GTK client
|
|
//! (design: punktfunk-planning `linux-client-rearchitecture.md`, Phase 0) so the desktop
|
|
//! shells and the Vulkan session binary build on one implementation — on Linux AND
|
|
//! Windows (the session binary runs on both; macOS stays `wol`-only, clients/apple is
|
|
//! the client there).
|
|
//!
|
|
//! Nothing here may depend on a UI toolkit: the presenter contract is `session`'s
|
|
//! channels (`SessionHandle`) and `video`'s `DecodedImage` (RGBA bytes, dmabuf fds +
|
|
//! plane layout, or a decoded VkImage) — how frames reach the screen is the consumer's
|
|
//! business.
|
|
//!
|
|
//! Audio is the one per-OS module swap: `audio.rs` (PipeWire) on Linux,
|
|
//! `audio_wasapi.rs` (WASAPI) on Windows — same public surface, picked here by `#[path]`
|
|
//! so `crate::audio` is the only name the session pump ever sees. `keymap` (evdev-keyed)
|
|
//! stays Linux: the session path uses pf-presenter's SDL-scancode table instead.
