enricobuehler	b390dd883b	feat(host/encode): VAAPI encode backend for AMD/Intel GPUs (Linux) ... The Linux host was NVENC/CUDA-only. Add a VAAPI encoder — one libavcodec backend (h264/hevc/av1_vaapi) covering both AMD (Mesa radeonsi) and Intel (iHD) — behind the existing `Encoder` trait, and turn `open_video`'s Linux arm into a vendor dispatcher: `PUNKTFUNK_ENCODER=auto|nvenc|vaapi` (default auto: NVENC when a CUDA frame or /dev/nvidia* is present, else VAAPI). The NVIDIA path is unchanged — auto resolves to NVENC on an NVIDIA box and the bitrate-probe loop moved verbatim into `open_nvenc_probed`. `VaapiEncoder` mirrors the NVENC hwframes pattern with AV_HWDEVICE_TYPE_VAAPI. The CPU-input path swscales packed RGB -> NV12 (BT.709 limited, VUI signalled) and uploads into a pooled VA surface (av_hwframe_transfer_data), preserving the low-latency model (infinite GOP, on-demand forced IDR, async_depth=1, CBR when the driver supports it). It works on a non-NVIDIA box with no capture changes: the capturer already falls back to CPU frames when its EGL->CUDA importer can't initialise (no libcuda). Live-validated on a Radeon 780M (RDNA3): hevc/h264/av1_vaapi all encode, HEVC/H264 decode cleanly with correct BT.709-limited colours, infinite GOP preserved. Zero-copy dmabuf import (the high-res perf lever) is next. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-19 15:35:49 +00:00
enricobuehler	9c8fa9340c	refactor: drop milestone names + consolidate clients; loss-recovery & rumble fixes ... Two bodies of work in one commit (the rename moved files the fixes also touched). Naming/structure cleanup (pre-launch): - Host modules m3.rs->punktfunk1.rs, m0.rs->spike.rs; CLI m3-host->punktfunk1-host, m0->spike; bare `punktfunk-host` now prints help. Types M3Options/M3Source-> Punktfunk1Options/Punktfunk1Source. - Clients consolidated out of crates/ into clients/: punktfunk-client-rs-> clients/probe (crate punktfunk-probe), client-linux->clients/linux, client-windows->clients/windows, punktfunk-android->clients/android/native (crate punktfunk-client-android; kept [lib] name=punktfunk_android so the JNI contract is unchanged). crates/ now holds only core + host. - Milestone codes M0-M4 purged from code/CLI/CLAUDE.md/README/docs/docs-site, kept only in docs/implementation-plan.md. docs/m2-plan.md-> docs/gamestream-host-plan.md. CI/gradle/flatpak paths updated. Client loss-recovery (video froze and never recovered after a brief drop): - Export punktfunk_connection_frames_dropped through the C ABI (the core already tracked it for the client keyframe-recovery loop; it was never reachable from the ABI clients). Regenerated punktfunk_core.h. - Apple (StreamPump + Stage2Pipeline) and Android (decode.rs) now poll frames_dropped and request a keyframe when it climbs -- the same loss-driven recovery Linux/Windows already had. Under infinite GOP the decoder silently conceals reference-missing frames, so the decode-error trigger rarely fires. Apple rumble robustness (worked then went spotty -- DualSense + Xbox): - Add CHHapticEngine stopped/reset handlers (rebuild on app background / audio interruption / server reset) and drop the permanent `broken` latch on a transient drive failure; latch only when the controller truly has no haptics. - Surface swallowed SDL set_rumble errors on Linux/Windows + diagnostic logging. Verified: cargo build/clippy/fmt --workspace, C-ABI harness, header drift. Not runnable on this box (verify in CI): Gitea workflows, gradle/Android, flatpak, Swift/decky.

enricobuehler	bbabc04bca	feat(hdr): Windows HDR10 + 10-bit end-to-end, negotiated; non-blocking capture recovery ... Adds true HDR (BT.2020 PQ) and 10-bit (HEVC Main10) streaming, negotiated so an 8-bit/SDR client is never sent a stream it can't decode, plus a robust fix for the capture losing the stream across a secure-desktop transition. Protocol (punktfunk-core/quic.rs): - Hello gains `video_caps` (VIDEO_CAP_10BIT / VIDEO_CAP_HDR), Welcome gains `bit_depth`, both as optional trailing bytes (back-compat). client-rs advertises 10-bit via PUNKTFUNK_CLIENT_10BIT; the connector advertises 0 for now (in-band detection drives the native clients). Regenerated punktfunk_core.h. Windows host: - 10-bit Main10: host enables it only when the client advertised VIDEO_CAP_10BIT AND PUNKTFUNK_10BIT is set; threaded through open_video → NVENC (profile Main10, pixelBitDepthMinus8). - HDR: when the captured desktop is scRGB FP16 (R16G16B16A16_FLOAT, HDR on), copy it to an FP16 surface, composite the cursor there, convert scRGB → BT.2020 PQ 10-bit (R10G10B10A2) via a shader, and encode HEVC Main10 with the BT.2020/PQ colour VUI (ABGR10 input). Fixes the freeze + cursor-trail that came from feeding FP16 into the BGRA path. Reacts dynamically to the HDR toggle. - Capture recovery: rebuild is now a single NON-BLOCKING attempt, throttled to ~4×/s, repeating the last good frame between attempts (format-tagged last_present). During a secure-desktop dwell SudoVDA's output is gone; the old blocking 12 s retry starved the send loop for seconds so the client timed out and disconnected — now the session stays fed (frozen) until the desktop returns. Also seeds a black frame on recovery. Apple client (PunktfunkKit): - Detects HDR in-band from the stream VUI (PQ transfer function), decodes to 10-bit P010, and presents via an rgba16Float + BT.2020 PQ CAMetalLayer with EDR; SDR path unchanged. Switches automatically on a mid-session HDR toggle. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 20:28:52 +00:00

enricobuehler	69ba6ec45d	feat(host/windows): NVENC D3D11 hardware encoder (--features nvenc) ... Zero-copy capture->encode on the GPU via the raw NVENC API (nvidia_video_codec_sdk sys + ENCODE_API; the safe wrapper is CUDA-only). Opens an NV_ENC_DEVICE_TYPE_DIRECTX session on the SAME ID3D11Device as the DXGI capturer (carried on the new FramePayload::D3d11), registers a pool of BGRA textures once, CopyResources each captured texture in and encode_picture; CBR/ULL, infinite GOP, P-only, forced-IDR for RFI. The DXGI capturer gains a D3D11 zero-copy output (selected, like the encoder, by PUNKTFUNK_ENCODER=nvenc) so capture+encode share textures. OFF by default (the nvenc feature pulls the NVENC SDK + cudarc): the default Windows host links without it (openh264 path). cudarc builds toolkit-less via the SDK ci-check feature (dynamic-loading). At link time --features nvenc needs nvencodeapi.lib (NVENC SDK, or an import lib generated from the driver's nvEncodeAPI64.dll) on PUNKTFUNK_NVENC_LIB_DIR. Both default and --features nvenc builds validated to compile+link GPU-less on the VM (import lib generated from the driver DLL). Runtime needs a real NVIDIA GPU.

enricobuehler	cbbeaa5c29	feat(host/windows): openh264 software H.264 encoder (GPU-less path) ... Windows Encoder impl via the openh264 crate (statically-bundled, BSD-2): low-latency screen-content config (Baseline/no-B-frames, bitrate RC, BT.709 limited, near-infinite GOP + forced-IDR recovery via request_keyframe), packed CPU pixels (BGRx/BGRA/RGB/RGBA/RGBx/BGR) -> I420 -> AnnexB with in-band SPS/PPS each IDR. Synchronous: submit encodes immediately, poll hands back the one AU, flush is a no-op. Windows open_video factory selects it (PUNKTFUNK_ENCODER=software|nvenc|auto; NVENC arm lands later), H.264-only with a clear error otherwise, SW bitrate ceiling. Unit-tested live on the VM: synthetic BGRx -> AnnexB IDR + SPS NAL. Unblocks the GPU-less capture->encode->FEC->send pipeline. Compiles clean on Windows + Linux.

enricobuehler	8425cd0826	fix(encode): probe each GPU's real max bitrate instead of failing (or blind-capping) ... Root cause of the Mac "session ended" at 880 Mbps / 1.3 Gbps: the host requests a bitrate NVENC can't express at any codec level and `avcodec_open2` returns EINVAL ("Invalid argument"), so the pipeline build fails after 4 identical retries and the session dies at encoder init — before a single video packet (which is why the client's UDP counters never moved). The ceiling is GPU/driver-specific: an RTX 4090 caps HEVC at ~800 Mbps (Level 6.2 High tier) and rejects above it, while an RTX 5070 Ti accepts 1.3 Gbps. Rather than hard-cap every build to a conservative guess (which would needlessly throttle capable cards), open_video now PROBES: open at the requested bitrate, and step down (codec spec ceiling, then 0.75x to a 50 Mbps floor) ONLY when this GPU returns EINVAL. Each GPU runs at its own real maximum — the 5070 Ti keeps 1.3 Gbps, the 4090 lands at 800 Mbps and streams instead of dying. Non-EINVAL failures (no GPU, bad mode, OOM) still surface immediately rather than being masked by retries. Codec::max_bitrate_bps is now just the first step-down candidate, not a clamp.

enricobuehler	bfd64ce871	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.
