enricobuehler	739a5f76bf	feat(apple): PyroWave Phase 5 — native Metal decode on Mac / Apple TV / iPad (§4.7) ... The Apple client now decodes PyroWave natively on the presenter's own MTLDevice — no MoltenVK, no upstream C++ in the app. Completes and wires up the decoder whose early working-tree snapshot rode along in 9127c346: - MetalWaveletShaders.swift: wavelet_dequant + idwt hand-ported from the vendored GLSL (STORAGE_MODE 0 only; subgroup scans → 32-wide simdgroups; DCShift spec constant → function constant; precision-1 split: fp16 levels 0-1 / fp32 2-4). - MetalWaveletDecoder.swift: Swift reimplementation of push_packet/decode_packet incl. the Phase-4 chunk-aligned window walk (FRAG chains, zeroed missing shards, the >half-blocks partial rule), init_block_meta's block-index space, and the 42-dequant + 13-idwt dispatch structure with encoder-boundary barriers. SOF-dims changes rebuild the size-dependent resources, which is also the mid-stream resize path. Ring of 4 output plane sets on the presenter's queue. - Presenter: pf_frag_planar (3xR8, the planar_csc.frag twin) + renderPlanar with a shared present tail; ReadyFrame carries an image enum (.video | .planar). - Stage2Pipeline: a dedicated PyroWave pump — no VideoToolbox machinery, no keyframe/re-anchor recovery (all-intra; partials render as localized blur by design), newest-frame-index staleness guard for late partials. - Opt-in: "PyroWave (wired LAN)" codec entry (probe-gated, ≈A13 floor via a real kernel-compile probe), selecting it advertises + prefers the codec and forces the session SDR (HDR/10-bit/4:4:4 caps dropped, plan contract). - Core ABI: punktfunk_connection_shard_payload() — the Welcome's negotiated shard payload, needed by native decoders to walk chunk-aligned AUs. - Validation: golden fixtures generated by the host encoder + upstream's own decoder (pyrowave_dump_golden, RTX 5070 Ti); the Metal decode PSNR-matches at 77-88 dB across all planes for dense AND chunk-aligned AUs, and a hole-punched partial still decodes. Parser unit tests cover the window walk, FRAG chains, broken chains, the half-blocks gate, and the block-index layout. Tests: apple 134 green (mac; iOS/tvOS build), host 312 w/ pyrowave on .21, core 148 w/ quic; clippy/fmt clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 12:16:43 +02:00
enricobuehler	83460cd2c0	feat(clients): unified stats vocabulary across every client + Moonlight comparison docs ... One stat model everywhere (design/stats-unification.md): four measurement points (capture/received/decoded/displayed), three stages that tile the interval exactly, and a HUD that shows the addition explicitly — end-to-end 14.2 ms p50 · 19.8 p95 · capture→on-glass = host+network 9.8 + decode 2.1 + display 2.3 replacing each client's ad-hoc mix of overlapping absolutes (the Apple HUD's three arrow lines that looked sequential but weren't), mean-vs-median decode times (Windows/Linux), missing same-host-clock flags (Windows/Linux), and three different names for the same capture→received measurement (probe's "reassembled", Apple/Android's "client", Windows/Linux's post-decode "lat"). Per client: Apple threads receivedNs through the VT decode via the frame refcon bit pattern so the decode stage exists at all (stage-1 fallback honestly degrades to a capture→received headline); Windows carries FrameTimes through the existing frame channel to the render thread and adds e2e p50/p95 post-Present; Linux stamps received at AU pop and rides decoded_ns on DecodedFrame to the paintable-set site; Android pairs receipt stamps with MediaCodec output buffers via the codec's pts round-trip (JNI stats array 14→16 doubles, indexes 0-13 unchanged). fps now uniformly counts received AUs; lost/(received+lost) per window, hidden at zero. docs-site gains "Understanding the Stats Overlay": what each line means, why the equation only approximately sums (percentiles), and a line-by-line Moonlight/Sunshine matrix — including that Moonlight has no end-to-end number and its "network latency" is an ENet control RTT, so punktfunk's headline must not be compared against any single Moonlight line. Verified here: linux client + probe + core check/clippy/fmt green, android native cargo-ndk arm64 check green. Pending: Windows CI + on-glass, swift test on the mac, on-device Android.

enricobuehler	b357934cb1	feat(clients): codec preference on Windows/Apple/Android clients (Phase 2b) ... Rounds out codec negotiation across the last three clients — each advertises what it can decode, builds its decoder from the resolved Welcome.codec, and exposes a "Video codec" preference picker. **Windows** (Rust, mirrors Linux): `decodable_codecs()` + `ffmpeg_codec_id()`; the D3D11VA and software FFmpeg decoders (and the mid-session D3D11VA→software demotion) open the negotiated codec instead of hardcoding HEVC; settings gain a `codec` field + reactor ComboBox; `--codec` CLI flag. **Apple** (Swift/C-ABI): AnnexB is now codec-aware — a `VideoCodec` enum drives H.264 vs HEVC NAL parsing / parameter-set extraction (`CMVideoFormatDescriptionCreateFromH264ParameterSets` for H.264, no VPS) and AVCC repacking; `PunktfunkConnection` advertises H264|HEVC via `punktfunk_connect_ex7`, reads `resolvedCodec` (`punktfunk_connection_codec`), and threads `videoCodec` into the stage-1/2 pipelines + `VideoDecoder`; SettingsView "Video codec" Picker (auto/HEVC/H.264). AV1 is left out (hosts don't emit it on the native path, and it's not an AnnexB codec). Test call sites updated. **Android** (Kotlin + Rust JNI): the JNI `nativeConnect` gains `preferredCodec`; the native decode loop picks the AMediaCodec MIME (`video/hevc`|`video/avc`) from `connector.codec` and advertises H264|HEVC; Settings `codec` field + Compose dropdown. Core/host/probe/Linux clippy + tests green (unchanged from 2a). Windows/Apple/Android compile on their platform CI (this Linux box can't build them — Windows toolchain / Xcode / the Android NDK's opus-cmake toolchain). All follow the Linux client's validated pattern. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-02 00:29:38 +00:00
enricobuehler	cde9004e8a	feat(apple): stage-2 presenter — explicit decode + Metal present + glass-to-glass ... Opt-in (Settings -> Presenter; `punktfunk.presenter`, default stage-1). Stage-1's AVSampleBufferDisplayLayer decodes AND presents internally with no per-frame callback, so neither decode nor present can be stamped or hand-paced. Stage-2 takes explicit control: - VideoDecoder: VTDecompressionSession, async output callback stamps decode-completion, session rebuilt on every IDR / format change. Unit-tested (testVideoDecoderAsyncCallbackDeliversPixels). - MetalVideoPresenter: CAMetalLayer + CVMetalTextureCache + a runtime-compiled BT.709 limited-range NV12->RGB shader, present at the next vsync. The CVMetalTextures + pixel buffer are held until the GPU completes. - Stage2Pipeline: pump thread -> decoder -> newest-ready 1-slot ring; the hosting view's display link drains it once per vsync and stamps capture->present (the display-link target time projected into CLOCK_REALTIME). - LatencyMeter gains record(ptsNs:atNs:offsetNs:); the HUD shows a capture->present (glass-to-glass, modulo host render->capture) line, skew-corrected via clockOffsetNs. Measured live ~11 ms p50 vs ~2.2 ms capture->client. - StreamView / StreamViewIOS host the CAMetalLayer as a sublayer + a CADisplayLink (NSView.displayLink on macOS) when stage-2; input capture + HUD unchanged. The session-active gates switch from `pump != nil` to `connection != nil` so capture engages without a StreamPump. Validated: builds macOS/iOS/tvOS; the decode half is unit-tested; the Metal present is live-validated on glass (correct image + the capture->present number). Colorspace is BT.709 SDR for now; 10-bit/HDR + a pacing policy are later. Plan: docs-site/content/docs/apple-stage2-presenter.md.

enricobuehler	8cceb93541	rename: lumen → punktfunk, everywhere ... Full project rename, decided 2026-06-10: - Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs. - C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h, PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl. PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants). - Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1. WIRE BREAK: clients must be rebuilt from this revision. - Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / …. - Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the persistent identity is unchanged, pinned fingerprints stay valid). - Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated. - scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated. Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of "desktop but no apps/settings" over the stream: plasmashell launched without XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and rendered an empty menu. The script sets the complete KDE session env (menu prefix, KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell. Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS, zero lumen references left outside .git.
