enricobuehlerandClaude Fable 5	fa822744ff	feat(core/host/android): phase-locked capture — frames arrive on the client's latch schedule ... The host's capture tick and a client's panel vsync are independent ~120 Hz oscillators; their drifting phase sweeps every frame's wait-for-latch across a full refresh period (measured on-glass: latch p50 oscillating 5.4-8.9 ms with a fixed margin) — the beat is the residual judder and the fat p95, and no client can fix it alone. Design: punktfunk-planning design/phase-locked-capture.md. Protocol (punktfunk-core): - PhaseReport (control 0x32, next to the clock family): the client's next display latch ALREADY CONVERTED to host clock (the skew offset lives only client-side), panel period, uncertainty, and the measured median arrival-lead — the controller's error signal. ~1 Hz, latest-wins. CLIENT_CAP_PHASE_LOCK advertises it; CtrlRequest::Phase + report_phase() + the C ABI mirror carry it. - The 0xCF host-timing tail grows a phase ACK (applied_phase_ns, 29-byte form) under the same strict-prefix append discipline — old readers parse the shorter forms; degradation pinned by tests. Host engine (arrival-slaved loop — no backend can move the source vsync, per the tick-ownership audit in the design doc): - PhaseCtl bridges control task → encode loop (the fec_target pattern, multi-field). PhaseController walks a per-frame HOLD before submit toward the client's reported lead hitting target = max(2.5 ms, uncertainty+1ms): 1 Hz adjust, 2 ms max step, 300 µs deadband, period-wrapping (the newest-wins capture slot makes a wrapped hold sample fresher content, not staler). A loop local, so every mid-stream rebuild keeps the lock; a new session re-acquires. PUNKTFUNK_PHASE_LOCK=0 disarms. Android reporter: the presenter's 1 Hz pf.present flush returns the window's measured latch p50; the async loop converts the vsync clock's next timeline monotonic→realtime→host and reports. Inert toward old hosts. Gates: docker amd64 clippy --all-targets -D warnings (host+core, nvenc) clean; core suite incl. the new wire tests; cargo ndk arm64 check/clippy clean. On-glass A/B vs the .173 host owed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 23:44:09 +02:00
enricobuehlerandClaude Fable 5	f9faab780e	tune(android): the latch margin drops to SF's real lead (2.5 ms) ... Each ms of submit-margin is a ms on every frame's display stage; SF's latch runs ~1-2 ms before present and the release is a sub-ms binder call, so 4 ms was padded. Measured (A024, 120 Hz game load): latch p50 8-10 → 5.4-8.9 (phase-drift dependent), paced stays 1-5/s. A device that misses at this margin shows it as a paced-counter rise, not stutter — the widen signal. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 23:44:09 +02:00
enricobuehlerandClaude Fable 5	a6ff0350e4	feat(android): frames target SurfaceFlinger's latch, not the GPU-render deadline — display 21→9.5 ms ... The remaining ~21 ms display stage was the conservative release target: the presenter aimed at the first frame timeline whose DEADLINE was still ahead, and the platform's deadline budgets for GPU rendering the app has yet to submit (presDeadline = 11.3 ms on the A024 — more than a full 120 Hz period). A decoded video buffer has no GPU work left; its only real constraint is SurfaceFlinger's own latch lead. Every frame paid a whole extra refresh of waiting for a budget it never used. next_target now gates (and subdivides) on the timeline's EXPECTED PRESENT minus a 4 ms latch margin; the glass budget reopens at that latch instant (expected present − margin) rather than the deadline, which under the aggressive gate can already lie in the past — an instant reopen would let two releases pile onto one vsync. A mis-gamble presents one vsync later, which is exactly what the deadline gate paid on every frame — the trade is one-sided. On-glass (A024, 2800×1260@120 HDR, game load): latch p50 21→8-10 ms, display 26,3→9,5 (pace 0,8 + latch 7,7), e2e 43,7→26,4 p50 / 29,2 p95, released=displays=120, paced≈0, forced=0. The latch now sits under one refresh interval — the vsync-latch floor. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 23:44:09 +02:00
enricobuehlerandClaude Fable 5	984f7be896	fix(android): the presenter paces to the panel's real grid, not the app's down-rated vsync ... On-glass (A024, 120 Hz panel, 120 fps session) the first presenter build released only 60/s and the HUD display term hit 40 ms. Root cause, in two layers: Android down-rates a game-category uid's choreographer stream to 60 Hz (frame-rate categories / game default frame rate), and under that override Display.getRefreshRate REPORTS THE OVERRIDE — so the presenter's panel grid read 16.67 ms on an 8.33 ms panel and the subdivision became a no-op, pacing the video at half rate and dropping every other frame. Three-part fix, verified live on the same device: - Kotlin passes the panel rate from the supported-modes TABLE (MainActivity.streamPanelFps — the mode list is not override-filtered) instead of display.refreshRate, and votes the app's render rate up via View.requestedFrameRate = streamHz (API 35+) while streaming. - The native vsync clock LEARNS the panel period from observed timeline spacing (downward-only: the finest spacing SurfaceFlinger ever reports is the true grid) and next_target subdivides the reported timeline onto it — full-rate on down-rated devices, a no-op where callbacks match the panel. - OnFrameRendered display/latch samples get the e2e clamp (0..10 s): a vendor's first callbacks can carry a garbage system_nano (observed: an epoch-sized latch max) that would poison every max it lands in. pf.present gained panelMs next to vsyncMs, and a one-shot cadence diagnostic logs Δ/timelines/spacing/panel on the third tick. After: released=120 displays=120 paced=0, pace p50 <1 ms, latch p50 ~16 ms idle / ~22 ms under game load (2 refresh intervals at 8.33 — the same composited-pipeline law the Apple client measured), HUD display ~17-26 ms vs 40 before.

enricobuehlerandClaude Fable 5	e08fd91cd1	feat(android): a timeline presenter — frames reach glass on the panel's schedule, not decode's ... The Android port of the Apple client's stage-4 deadline discipline, closing the side-by-side feel gap (both clients 120 Hz; Android released decoded buffers the instant they appeared, with zero vsync awareness — the latch phase inherited every network+decode jitter and bursts queued behind the display). The presenter (async loop only; the sync loop stays the untouched escape hatch behind the Low-latency toggle): - decode/vsync.rs: an AChoreographer thread (dlsym'd like the other above-floor symbols) publishing the panel's vsync grid + frame timelines (postVsyncCallback, API 33; postFrameCallback64 fallback on 31/32) and ticking the decode loop's event channel. Started lazily on the first decoded frame. - decode/presenter.rs: a newest-wins slot (Lowest latency, default) or a 1-3 frame smoothing FIFO with preroll/underflow re-arm (Smoothness) between decode and release; a glass budget of exactly ONE undisplayed release in flight, reopened at the target timeline's DEADLINE (SurfaceFlinger's latch — reopening at present time would halve the sustainable rate) with a 100 ms stale force-open backstop; the release itself via releaseOutputBufferAtTime(expectedPresent) so the latch phase is deterministic. debug.punktfunk.presenter=arrival sysprop restores the legacy path for a rebuild-free on-device A/B. - Metrics: DisplayTracker is now always-on and carries the release stamp, so the display stage splits into pace (decoded→release) + latch (release→displayed); a 1 Hz pf.present logcat line (released/displays/ paced/noBudget/forced/qDry + pace/latch p50/max + measured vsync) makes a HUD-off wireless A/B readable; nativeVideoStats grows to 30 doubles (26=paceP50, 27=latchP50, 28=presents, 29=presenterActive; 0-25 frozen) and the DETAILED HUD prints the split + presents. - Intent parity: present_priority/smooth_buffer — the Apple client's stored values and labels — as globals, profile-overlay fields (round-trip + scope markers), and Settings pickers under Decoding; threaded through nativeStartVideo into the presenter config. Verified: cargo ndk check/clippy clean for arm64 (the two type_complexity warnings are pre-existing audio/mic ones), armv7 via the kit gradle task, host cargo check clean, rustfmt clean, gradle :app/:kit unit tests all pass. On-device before/after on the Nothing Phone 3 still owed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 23:44:09 +02:00
enricobuehlerandClaude Fable 5	87b6fa8813	feat(android): the panel is pinned to the stream's refresh, and touch skips the vsync batch ... Three quick latency wins for phones, ahead of the presenter rebuild: - setStreamDisplayMode: the window-level preferredDisplayModeId is pinned to the stream's refresh (exact rate, else the smallest integer multiple, else the highest available) for the session. The surface-level frame-rate hint alone is advisory and some OEM refresh governors (Nothing OS's LTPO logic among them) ignore it for third-party apps — leaving a 120 Hz session presenting on a 60/90 Hz panel. nativeVideoSize gained a trailing refreshHz element for this (old readers index only 0/1). TV keeps the native HDMI mode switch instead. - The surface hint itself now passes compatibility = FIXED_SOURCE on every form factor: the stream is fixed-rate video the client cannot re-pace; DEFAULT invited governors to not switch. - requestUnbufferedDispatch(SOURCE_CLASS_POINTER) on the hosting view while streaming: touch/pointer events were vsync-batched — up to a frame of input latency the stream shouldn't pay. - The HUD polls the panel's live refresh each second and flags '⚠ panel N Hz' when it sits below the stream rate, so an unpinned panel is visible instead of reading as inexplicable judder. Stale nativeStartVideo kdoc (low-latency 'off, the default') corrected — it defaults ON under low_latency_mode_v2. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 23:44:09 +02:00
enricobuehlerandClaude Opus 5	6a6be17ce7	fix(client/android): a session that receives no video at all now asks, and says so ... The keyframe backstop added for the black LG TV only arms while AUs are actually going into the decoder (`fed > fed_at_output`) — deliberately, so an idle stream never asks for anything. That leaves its mirror image uncovered: a session that receives NOTHING. A decoder cannot be starved of output when it was handed no input, so no signal in either loop fires, and the session sits connected — audio, input and the control plane all alive — behind a black surface. That state is what a user just reported as "the stats are all basically 0": fps and Mb/s are counted at AU receipt (`note_received`), so all-zero stats with a drawn overlay means the decode thread started and received nothing. Same bug as the black screen, seen from the HUD. Both loops now watch for it: nothing received 1.5 s into a session ⇒ request a keyframe and log it, re-asking every 2 s while it lasts. Where it can help it does — the host encoding fine while every picture references an IDR this client never saw is precisely a keyframe request away. Where it can't, the log line is the point: "no video received N ms into the session" separates "the host never sent a picture" from "we received AUs and lost them", which no previous black-screen report could distinguish. Not a root cause. The remaining occurrences are still unattributed — this makes the next report diagnosable and recovers the case that is ours to recover.

enricobuehlerandClaude Opus 5	e44baf6768	fix(client/android): a decoder fed nothing it can decode must ask for a new anchor ... An Android TV box reported a black screen with a perfectly healthy HUD: AUs arriving at 40 fps, ~312 bytes each. That size is all-P-frames — no IDR anywhere in the window, and nothing asking for one. The stats being readable is the rest of the story: the overlay is a layer over the SurfaceView in the same window, so the panel was fine and the surface simply never received a frame. The decode thread only starts at `surfaceCreated`, so a slow box can be handed the stream mid-GOP. A hardware decoder does not error on references it never had; it emits nothing at all. Under infinite GOP the host sends no further IDR unless asked, and neither Android loop ever asked: every recovery trigger they have keys off a drop, a gap or a decode error, and a decoder that quietly produces nothing trips none of them. The session stayed black for its whole life. The shared gate has this case (`on_no_output`, which pf-client-core and the Apple client both feed) but its per-AU streak counts one-in/one-out decodes, and MediaCodec is pipelined — "this AU produced no output" is not something these loops can observe. A wall-clock silence window is the same signal in the shape Android can measure: fed for 500 ms with nothing coming back arms the freeze and requests a re-anchor keyframe, and the gate's deadline keeps re-asking until one lands. 500 ms so it can never fire on a decoder that is merely slow to spin up. Also log the first presented frame. The periodic tally starts at 300 rendered frames, which is no help whatsoever on a session that renders none — its absence is what separates "never reached glass" from "reached glass and looked wrong".

enricobuehler	8172e819a4	fix(client/android): the JNI crate wouldn't build under the unsafe-op lint ... `unsafe_op_in_unsafe_fn` is denied workspace-wide, and two operations in the render-callback path were still bare inside their `unsafe fn` — so every Android build failed at `cargo ndk`, before any Kotlin work could reach a device. Pre-existing on main and unrelated to the Android settings/profiles work; found by building the APK for it. Both get the explicit block and the SAFETY note their neighbours in the same file already carry: the reclaimed pointer is the one `install_render_callback` leaked, and the callback's `userdata` is that same pointer, alive for as long as the codec that delivers the call.	2026-07-29 12:17:18 +02:00
enricobuehlerandClaude Fable 5	a784682d4c	fix(client/net): split the receipt stamp from the pull + bleed standing latency ... The two-pair investigation (wired Mac clients stuck at a rock-steady ~18-19 ms "network" that survived the load ending and cleared only on reconnect) exposed two structural gaps, one of measurement and one of recovery: - Receipt was stamped at the hand-off PULL (Swift nextAU, pf-client-core, Android decode loops), not at reassembly completion — so any client-side standing state between the reassembler and the pull read as NETWORK latency, undiagnosable from the HUD. ABI v9: `PunktfunkFrame`/`Frame` grow `received_ns`, stamped by `Session::poll_frame` as the AU crosses the session boundary. Every embedder now uses the core stamp; the Apple client keeps the pull instant as `AccessUnit.pulledNs` and shows the receipt→pull wait as its own "client queue" term (detailed HUD tier from 2 ms + a `queue_p50` stats-log field). Decode stages keep their pull anchor on all platforms, so no historical stage shifts meaning. - The jump-to-live detectors deliberately ignore anything under 6 queued frames / 400 ms behind — so a small, constant, loss-free elevation (a sub-frame standing backlog, or a stale clock offset after a wall-clock step/slew) is carried for the rest of the session. New third detector (`StandingLatency`, unit-tested ladder): window-MIN one-way delay ≥ 10 ms above the session floor with zero loss for ~4.5 s escalates gently — a free clock re-sync first (an applied re-sync re-bases the floor), then at most 3 flush+keyframe bleeds sharing the jump-to-live cooldown, then a loud disarm naming what it means. Loss windows reset the run: congestion belongs to FEC/ABR, not this detector. Also: mid-stream re-sync apply/discard logs debug→info — they are the forensic trail for the stale-offset case and were invisible in the field.

enricobuehlerandClaude Opus 4.8	f439b69451	refactor(android/W8): split decode.rs into decode/ directory module ... Break the 1747-line clients/android/native/src/decode.rs into a decode/ directory module (mod.rs + 5 concern submodules): - decode/setup.rs : codec creation + low-latency config + thread/frame-rate tuning + HDR static-info encode - decode/display.rs : DisplayTracker + render-callback registration + HDR dataspace - decode/latency.rs : realtime clock + decoded-pts / user-flags stat recording - decode/sync_loop.rs : the synchronous poll decode loop (+ feed/drain) — moved WHOLE - decode/async_loop.rs : the event-driven async decode loop (+ helpers) — moved WHOLE decode/mod.rs keeps the consts, DecodeOptions, and the `run` entry point + the `codec_mime`/`codec_label` re-export, so every crate::decode::X path stays byte-stable. The module has no decoder struct (free functions + small types), so both decode loops move byte-for-byte and their separately-inlined received-stat recording is NOT unified. 16 helper fns/types became pub(super) for sibling access; zero field bumps. lib.rs unchanged (`#[cfg(target_os="android")] mod decode;` resolves to decode/mod.rs). Verified: cargo-ndk check (aarch64-linux-android, clean) + the gradle cargoNdkDebug build (arm64-v8a / armeabi-v7a / x86_64). On-device runtime re-verification still owed per the plan (the two decode loops are a hot path). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-17 15:06:24 +02:00
