enricobuehlerandClaude Fable 5	ffc7aec91a	feat(encode/pyrowave): log which GPU pyrowave picked — the selection stays put, by decision ... WP4.5's device-selection half, closed as the observability intermediate after TWO selection designs died in adversarial review: - Attempt #1 (d26bcf05, withdrawn): match pf_gpu::selected_gpu(). Its Linux auto arm answers "the NVIDIA GPU" whenever /dev/nvidiactl exists, moving the encoder off the iGPU that can import the compositor's dmabufs on an Intel-compositor + NVIDIA-present laptop — import failures feed the process-wide raw-dmabuf latch, which never un-latches. - Attempt #2 (this session, withdrawn before commit): anchor on the PUNKTFUNK_RENDER_NODE-else-renderD128 node via VK_EXT_physical_device_drm. Render minors are driver-BIND-ORDER artifacts, not display topology: on the common AMD-iGPU + NVIDIA-display desktop, in-tree amdgpu binds before out-of-tree nvidia, so the anchor deterministically picks the idle iGPU while the compositor allocates on NVIDIA — the same latch, opposite polarity, behind a success-looking log. The correct oracle is evidence of which device ALLOCATED the capture buffers — producer identity from the capture negotiation, threaded per session into this open. Until that plumbing exists, selection stays first-usable, both call sites still share one selector (pure over the device list, so capture_modifiers and open_inner cannot diverge — including across an in-place resize's re-open, which does not renegotiate capture), and the open logs ONE greppable line: picked vendor/device, the anchor node and its owner (DRM render major/minor, VK_EXT_pci_bus_info fallback), and the console's selected GPU. A wrong-device session on a multi-GPU host used to be completely invisible; a field report can now show it. No WARN arm on purpose: the wrong-pick direction inverts between the laptop and desktop topologies, so a mismatch is not evidence of a wrong pick, and a warning that fires forever on healthy hosts teaches people to ignore warnings. Decision recorded against the audit's framing: manual console GPU selection stays unhonored by pyrowave on Linux (the Windows twin honors it) — honoring console-mutable state without per-session threading is what made attempt #1 unsafe. Verified on the 780M: the line resolves all three identities (1002:15bf x3, DRM-props match live); full pyrowave on-glass suite green; selection behaviour byte-for-byte unchanged.

enricobuehlerandClaude Opus 5	fdded5b8c3	fix(encode/pyrowave): refuse a frame that isn't the session's mode ... PyroWave never checked frame dimensions against the session, and it applies no alignment — `width`/`height` are the negotiated mode verbatim — so a mismatched frame was encoded edge-smeared or cropped, silently, forever. Every other Linux backend already refuses exactly this, with this shape, in `submit`: libav-NVENC (`linux/mod.rs`), VAAPI (`vaapi.rs`) and openh264 (`sw.rs`) all carry the same `ensure!`. PyroWave was the only one that didn't. That is the justification; an earlier draft cited `vulkan_video.rs` instead, which is the weaker precedent — it bails in its Dmabuf arms only, and its CSC path and CPU arm have no dimension guard at all. Mostly this is a wrong-picture bug and not a memory-safety one: `rgb2yuv.comp` clamps every fetch with `min(p, textureSize - 1)` and the CPU arm uploads `min(len, need)` into a session-sized image. But it also closes a narrow real hazard that was not in the filing: `import_cached` keys on `(st_dev, st_ino)` and returns the cached `VkImage` on a hit WITHOUT rechecking the extent, and unlike the capture side it is never cleared on a renegotiation — so a dmabuf inode recycled across a shrinking renegotiation would hand the encoder an image sized for the old, larger allocation. This check closes that route. ⚠ Recorded at the code because it changes the failure mode, not just the detection: a mismatch is NOT always transient. A compositor-initiated PipeWire renegotiation updates the capturer's size in place and signals nothing the encode loop reads, so it can be a permanent new steady state — and `reset()` reopens at the same dimensions by construction, so the host's five-reset budget cannot recover (~3.1 s of frozen stream, then the session ends) where before it would have streamed on with a wrong picture. For a real mode change that trade is clearly right; for a 16-row KWin mismatch it is not, and the proper fix is for the host to classify this error as a PIPELINE rebuild rather than an encoder reset. Filed, not done here. The device-selection half of WP4.5 was written, reviewed and WITHDRAWN — see the handoff doc. Matching the selected render GPU regresses the hybrid Intel-compositor + NVIDIA-present topology this project has a live field report for, because `selected_gpu()` answers NVIDIA whenever `/dev/nvidiactl` exists regardless of where capture actually runs.

enricobuehlerandClaude Fable 5	47a23bec12	fix(encode/vulkan): unwind every open/import leak, and serve 24-bpp CPU instead of dying on it ... Phase 5's Linux half (audit WP5.1 + WP5.4), each item shaped by the review that rejected the obvious fix: Dmabuf import unwind (vk_util): every failure after create_image leaked the VkImage, and the dup'd dmabuf fd leaked as a raw i32. The sharp edge is that a SUCCESSFUL vkAllocateMemory transfers fd ownership to Vulkan (vkFreeMemory closes it), so the naive close-on-error is a double close that clobbers whatever unrelated descriptor recycled the number. The dup now lives in an OwnedFd released exactly in the allocate-success arm; every other path drops it once, and bind/view failures free image+memory. PyroWave open unwind: open_inner had ~20 fallible steps that each leaked everything before them (instance, device, pyrowave objects, the whole CSC pipeline). Rather than a parallel teardown guard — whose reviewed hazards were a null-unsafe pyrowave_encoder_destroy and a drifting duplicate of Drop — Self is now constructed right after create_device with every later resource null, and the existing Drop (wait-idle first, pw_enc null-guarded, delete-nullptr and VK_NULL_HANDLE destroys are no-ops) is the single unwind path for error and normal teardown alike. The ensure_cpu_rgb staging twins (create/allocate/bind, both backends) and the RGB-direct make_view pair get the same discipline via a shared make_host_buffer. Observed on hardware: 32 forced import failures, zero fd drift (the new import_failure_leaks_no_fds smoke on RADV). 24-bpp CPU service (WP5.4): pixel_to_vk had no mapping for the packed Rgb/Bgr the PipeWire portal negotiates, so a session committed to a path the backend could not serve and died at its first frame. The filed open-gate was rejected as a half-mirror — the dmabuf axis is keyed by fourcc at submit, unknowable at open — so instead the CPU axis is SERVED: a 3-to-4 expand at the staging upload (normalize_cpu_rgb, the CPU twin of WP1.4's swscale expand), order-preserving for the CSC samplers and BGRA-forced for the RGB-direct encode source, whose session pictureFormat is B8G8R8A8 — the on-glass run caught R-first sources violating VUID-vkCmdEncodeVideoKHR-pEncodeInfo-08207, a mismatch that predates this change for plain Rgbx CPU sources. The dmabuf axis feeds pf-zerocopy's raw-dmabuf degrade latch (3efbe416) from both Vulkan import caches — deterministic refusals flip capture to CPU delivery, which now serves every format capture produces; transient OOM and native-NV12 sessions are excluded. RECORDING-state hygiene: the fallible recording prefix (cursor prep, import, staging) now resets the command buffer on error instead of leaving it RECORDING for the next begin to trip VUID-vkBeginCommandBuffer-commandBuffer-00049; PyroWave's submit-level blanket reset is replaced by the same scoped shape, closing its fence-timeout hole where a reset hit a PENDING buffer (VUID-vkResetCommandBuffer-commandBuffer-00045). Verified: docker linux/amd64 4-leg gate green; RADV 780M on-glass under the validation layers at 1920x1080 — all 10 smokes pass (including the new 24-bpp CSC + RGB-direct legs and both channel orders), decoded colour truth checked with ffmpeg, and the only remaining validation messages are the two documented VALVE-extension layer gaps plus a pre-existing pyrowave shader/feature mismatch now filed in the planning doc.

enricobuehlerandClaude Opus 5	ef239691df	feat(encode): make cursor blending a queryable capability, not an assumption ... `open_video`'s `cursor_blend` argument was a request with no answer: lib.rs did `let _ = cursor_blend;` and only three backends ever read `CapturedFrame::cursor`. So a session could ask for a composited pointer, get a backend that silently discards it, and stream with no mouse cursor and nothing in the logs. Two separately-confirmed audit findings — the VAAPI dmabuf path and the libav-NVENC CUDA path — are symptoms of that one hole. `EncoderCaps::blends_cursor` makes it a fact each backend states. The four exhaustive `EncoderCaps { .. }` constructors mean adding the field is a compile error until every backend answers, which is the enforcement mechanism for future backends rather than a side effect. Vulkan Video answers from its ACTUAL configured source rather than statically: only the CSC path composites (`prep_cursor` feeds the compute shader), while the RGB-direct/EFC front-end and the native-NV12 source have no compositing stage at all and merely warn once that the pointer is being dropped. `open_video` warns when a session asked for blending and the opened backend cannot deliver it. A warning is deliberately all it does: `open_video` cannot re-plan capture, so refusing would trade a missing pointer for a dead session. The host owns `plan.cursor_blend` and is the only layer that can fall back to capturer-side compositing — this gives it something to base that on. Enforcement is NOT included. The reviewed design proposed refusing the client's host-composite flip to keep the client drawing its own pointer, but `CursorRenderMode` is client->host only: there is no host->client counterpart, so refusing yields no pointer at all — the same failure it claimed to prevent.

enricobuehlerandClaude Opus 5	6c97c00add	fix(encode/pyrowave): the RDO block-index cap must cover 4:2:0, not just 4:4:4 ... The vendored rate controller packs the 32x32 block index into the low 16 bits of `RDOperation::block_offset_saving` (pyrowave-sys patches/0002). Past u16::MAX the index collides with the `saving` field, the resolve over-credits, and the emitted payload can overshoot the buffer `pyrowave_encoder_packetize` writes into — whose only bounds check is an `assert` that the Release (NDEBUG) vendored build compiles out. There is no Rust-side guard behind it. All three callers of `pyrowave_mode_fits_rdo` hardcoded 4:4:4, leaving 4:2:0 unchecked — but 4:2:0 overflows too, just later: 8192x6144 is 73728 blocks and 8192x8192 is 98304, while `Codec::PyroWave.max_dimension()` permits 8192 per axis, so both are reachable from a client-requested `mode=WxHxFPS`. Worse, the host's only use of the helper (native/handshake.rs) is a 4:4:4 -> 4:2:0 downgrade, so an oversized mode was actively routed INTO the unguarded branch. The cap now lives in `validate_dimensions`, checked against 4:2:0 — the most permissive chroma, so a mode that cannot fit there fits no PyroWave session at any chroma. That is the single chokepoint both the negotiator (handshake.rs:180) and `open_video_backend` already run. Both encoder opens additionally check the chroma actually being opened: the 4:4:4 half, plus defence in depth for the `PUNKTFUNK_ENCODER=pyrowave` lab override. Not dormant: punktfunk-host has `default = ["pyrowave"]` and no build passes `--no-default-features`, so these backends ship in every host binary. Tests pin the arithmetic (8192x6144 = 73728, 8192x8192 = 98304, 7680x4320 still fits) and assert the cap does not leak to H.265/AV1, which have no such controller.

enricobuehlerandClaude Opus 4.8	a38adad943	fix(encode): bound GPU waits, validate encode status, repair command-buffer and cache invariants ... Five of the nine medium findings from the pf-encode sweep. The remaining four need cross-crate plumbing or an unwind refactor and are deliberately left out. - vulkan_video `enqueue` waited on the backpressure fence with `u64::MAX`. That wait runs ON the host encode thread — the same thread the stall watchdog's `reset()` would run on — so a wedged GPU parked the one thread that could recover the session: no error, no reset, and teardown blocking on the join. This is the DEFAULT encode path for AMD/Intel Linux hosts (both shipped build recipes enable `vulkan-encode` and `vulkan_encode_enabled()` defaults true). Now bounded by ENCODE_FENCE_TIMEOUT_NS with expiry surfaced as an error. - vulkan_video `import_cached` evicted a cached dmabuf import and destroyed its image/view/memory with no fence wait, while up to `ring_depth - 1` submitted frames may still reference it — a GPU-side use-after-free. `Drop` and `reset` both idle first; this was the one unguarded destroy. Now idles before the eviction loop, guarded on the length test so the steady state pays nothing. - vulkan_video `read_slot` never asked for the encode's operation status, so a FAILED encode was indistinguishable from a successful one and its feedback was read as if it described real bitstream. Now requests WITH_STATUS_KHR and refuses anything that is not COMPLETE. - linux/pyrowave `encode_frame` opens its recording window early and has six fallible steps inside it; every one returned with `cmd` still RECORDING, and nothing repaired it (one `begin_command_buffer` in the file, and neither `reset()` nor `Drop` touches `cmd`), so the next frame called `begin` on a recording buffer — invalid usage. `submit` now resets the buffer on error; legal on all these paths since the pool carries RESET_COMMAND_BUFFER and the buffer is not pending. - windows/pyrowave `encode_frame` ignored `frame.width`/`height` and imported planes at the encoder's configured extent, so a ring recreate at a new mode (the IDD capturer does this autonomously on a confirmed descriptor change) read the planes under a stale VkImageCreateInfo. Added the size guard its QSV and AMF siblings already carry, and keyed the plane cache on (address, width, height) so a recycled COM address cannot resurrect an import of a different size. NOTE: a recycle at the SAME size is still theoretically possible; the complete fix keys on the capturer's ring generation and needs that plumbed onto `PyroFrameShare`.

enricobuehlerandClaude Opus 4.8	04e4394ee0	fix(encode): close the two teardown memory-safety holes in the reset paths ... Both surfaced in a post-refactor quality sweep of pf-encode and were then verified against the source (and, for pyrowave, against the C side). - PyroWave (BOTH platforms): `reset()` destroyed the encoder and, when the rebuild failed, returned `false` leaving `pw_enc` pointing at the freed object — `Drop` then destroyed it a second time. `pyrowave_encoder_destroy` is a plain `delete` (pyrowave_c.cpp:1184, which also reads `encoder->device` afterwards) with no null check, so this is a real double free. The failure branch is not vacuous: the rebuild fails when the device is lost/OOM, which is exactly the state that makes the stall watchdog call `reset()` in the first place, so the host corrupts its heap on the path that runs when things are already going wrong. Now nulls `pw_enc` before the fallible create, publishes only on success, and null-guards both `Drop` and `encode_frame` (the Windows `Drop` already guarded `sync` this way). - QSV: `reset()` dropped `pending` — each entry owning the `Box<BsBuf>` the runtime writes into asynchronously — BEFORE `MFXVideoENCODE_Close` aborted those operations, so the VPL runtime could write into freed heap. The preceding drain is best-effort and bails on the first `Err`, i.e. precisely the wedged-encoder case that triggers the reset. Fixed by ordering: Close, then clear. The full-teardown path was already correct (`Inner` declares `session` before `pending`, and fields drop in declaration order).

enricobuehlerandClaude Fable 5	75474dcc90	fix(pyrowave): guard 4:4:4 modes that overflow the rate controller's block index ... The vendored rate controller packs its wavelet block index into 16 bits (RDOperation.block_offset_saving), so a mode whose 32x32-block count exceeds u16::MAX wraps inside the controller and corrupts the bitstream — ~8K-class 4:4:4 territory. Compute the exact count (`block_count_32x32`, the counting walk of upstream init_block_meta, pinned against the validated Apple WaveletLayout) and expose `pyrowave_mode_fits_rdo`; the negotiator downgrades such a session to 4:2:0 before the Welcome (the honest-downgrade channel), and both encoders refuse outright if one slips through rather than emit a wrapped stream. Vendor patches: 0002-rdo-saving-clamp (analyze_rate_control.comp clamps the saving accumulation to the target, same overrun class as 0001; slangmosh.hpp regenerated), 0003-devel-encode-16bit-read (devel tool y4m 16-bit plane reads; tool-only, kept so the vendored source stays honest).

enricobuehlerandClaude Opus 4.8	9fe9c451dc	perf(pyrowave): pool encoder scratch buffers + fix client parser O(n²) — lift the 2.5 Gbps wall ... Real-world PyroWave streaming maxed ~2.5 Gbps with sagging fps while raw transport does 4.8. Root-caused to serial per-frame paths at BOTH ends (the transport was never the limit); this fixes the two dominant ones. Host (vendored shim, patch 0004): pyrowave_encoder_encode_gpu_synchronous allocated four Vulkan buffers (meta + bitstream, Device + CachedHost) on EVERY frame. At 240 fps with MB-scale bitstreams that per-frame allocator churn stalled the encode itself. Pool them on the encoder and reuse across frames (recreate only on a size grow); the sizes are session-fixed, so it is pure reuse after frame 1. On an RTX 4090 the 5120x1440 submit+fence-wait drops ~15 ms -> ~1 ms, i.e. the host serial ceiling goes 64 -> 1025 fps (444+HDR 44 -> 614). Safe under the synchronous encode model; re-validated by pyrowave_win_smoke (Windows) and pyrowave_smoke/_444 (Linux). Applies to both host encoder paths (they share the shim). Client (Apple Metal decoder): WaveletBitstream.parse reserved the payload buffer per packet (reserveCapacity(count + words), an exact realloc each of ~3000 packets/frame => O(n²)) and copied word-by-word. Reserve once up front and memcpy each packet's coefficients in one shot (all Apple platforms are little-endian, so the wire's LE u32s land verbatim; memcpy is alignment-free). 5.44 ms -> 0.055 ms per 1.44 MB frame (25x); byte-identical (parser unit tests + golden-frame PSNR unchanged). Also: - native.rs: PUNKTFUNK_PYROWAVE_MAX_MBPS caps PyroWave's open-loop Automatic bitrate pin for hosts on a constrained link (unset => no cap; an explicit client rate bypasses it). The pin is all-intra + ABR-off, so at a high pixel rate it can outrun the fabric (4:4:4+HDR 5120x1440@240 pins ~5.3 Gbps, over a 5 GbE link) and the overshoot just becomes loss. - pf-encode caps(): report the real opened chroma instead of a hardcoded 4:2:0 default, so a genuine 4:4:4 session no longer trips the spurious "encoder chroma disagrees with the negotiated Welcome" warn. Also fix a latent Windows reset() that rebuilt at 4:2:0 for a 4:4:4 session. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-18 19:09:23 +02:00
enricobuehlerandClaude Fable 5	188edde2b3	feat(pyrowave): Windows host HDR + 4:4:4, Rust client HDR present ... Phase 3 of design/pyrowave-444-hdr.md. A PyroWave session now negotiates HDR (10-bit) and 4:4:4 on a Windows host exactly like HEVC/AV1, and the Linux client presents it through the real HDR10 path. Host (Windows): BgraToYuvPlanes becomes mode-aware — SDR/BGRA and HDR/scRGB variants at half- or full-res chroma. The HDR passes reuse HdrP010Converter's exact colour math (scRGB -> PQ BT.2020 limited studio codes, verified by hdr_p010_selftest) but write P010-style MSB-packed codes into two separate shareable R16_UNORM/R16G16_UNORM textures; chroma keeps the pyrowave family's centre-sited 2x2 box. idd_push pins the composition to the NEGOTIATED depth (SDR sessions force advanced color off as before; 10-bit sessions enable it and ride the FP16 ring), and the descriptor poller re-asserts that state instead of following display flips the fixed-format encoder can't. The encoder imports 8/16-bit planes per session and stamps the sequence header's BT.2020/PQ/matrix bits on HDR (stamp_color_bits, extending 574e3e4e's range stamp); supports_10bit/can_encode_10bit/can_encode_444 gates open (HDR Windows-only — Linux capture has no HDR source). Client: the plane ring becomes R16_UNORM for 10-bit sessions (with a STORAGE_IMAGE format probe), the planar CSC pass joins the HDR10 swapchain rebuild (set_hdr_mode previously destroyed it without rebuilding — latent), st.hdr follows frame.color.is_pq(), and the planar push constants carry depth-10 MSB-packed rows + the PQ tonemap mode, identical to the NV12 arm. Verified: .173 (RTX 4090) deploy-config clippy + fmt + wire tests + the extended pyrowave_win_smoke (10-case {SDR,HDR}x{420,444} matrix incl. R16 imports and header stamps); .21 (RTX 5070 Ti) clippy across 4 crates, host 186 tests, client/presenter/encode tests, both Linux GPU smokes.

enricobuehlerandClaude Fable 5	4861824e7d	feat(pyrowave): Linux 4:4:4 encode — per-pixel CSC, full-res chroma, gate open ... Phase 2 of design/pyrowave-444-hdr.md. can_encode_444(PyroWave) now returns true on Linux, so a client that advertises VIDEO_CAP_444 (the 4:4:4 setting) and prefers PyroWave negotiates a full-chroma wavelet session end to end (the client decoder side landed in 5eb930e7). - rgb2yuv444.comp: the 4:4:4 twin of rgb2yuv.comp — one invocation per pixel, full-res interleaved RG8 CbCr, no box filter/siting, byte-identical BT.709 limited coefficients; compiled .spv committed (glslangValidator -V, matches the existing shader's toolchain). - Encoder: chroma-conditional pyrowave create (open + reset), full-res chroma plane + views, per-pixel dispatch, 4:2:0-only even-dims check. - Tests: decode oracle grows a 4:4:4 mode (YUV444P CPU readback); pyrowave_smoke_444 round-trips plane means AND drives the busy test card at the ~2.6 bpp operating point asserting in-budget + run-to-run deterministic AU sizes — the exact regime that silently corrupted before the vendored payload_data fix (patches/0001), so this doubles as its regression test. Verified on .21 (RTX 5070 Ti): clippy -D warnings, host tests, and both GPU smokes (pyrowave_smoke + pyrowave_smoke_444) green.

enricobuehlerandClaude Fable 5	5eb930e71d	feat(pyrowave): negotiation plumbing for 4:4:4 + HDR — thread chroma/depth/ColorInfo end to end ... Phase 1 of design/pyrowave-444-hdr.md. No behavior change yet: the handshake's 4:4:4 gate now admits PyroWave (probe = can_encode_444(codec), capture gate inherently satisfied — the wavelet path always ingests an RGB source and does its own CSC), but can_encode_444 stays false for PyroWave until the per-OS full-res-chroma CSC variants land (Phase 2 Linux, Phase 3 Windows), so every session still resolves 4:2:0/8-bit. - Both host encoders take the negotiated ChromaFormat (bail on 444 for now); the PUNKTFUNK_ENCODER=pyrowave lab override pins 4:2:0. - Bitrate: the automatic ~1.6 bpp pin resolves AFTER depth+chroma and scales x1.625 for 4:4:4 / x1.15 for 10-bit (factors from the Phase-0 fixture matrix); the mid-stream mode-switch re-resolve threads the session's values. - Client: PyroWaveDecoder builds its plane ring (full-res chroma when 444) and creates the upstream decoder from the negotiated chroma, keeps chroma fixed across mid-stream resizes, drops the even-dims requirement for 444, and returns the negotiated Welcome ColorInfo as the frame colour contract instead of hardcoded BT.709 (the wavelet bitstream has no VUI). Verified on .21 (RTX 5070 Ti): clippy -D warnings (host+client+encode), host 186 tests, client + pf-encode tests, fmt, and the pyrowave_smoke GPU round-trip through the patched vendored lib (97cf15e3).

enricobuehlerandClaude Opus 4.8	574e3e4e3f	fix(pyrowave): signal ycbcr_range=LIMITED in the sequence header ... pyrowave's encoder fills the BitstreamSequenceHeader with `= {}` and its C API offers no way to set colour/range, so it signals ycbcr_range=0=FULL — but both host CSCs (rgb2yuv.comp on Linux, BgraToYuvPlanes on Windows) always emit BT.709 LIMITED Y'CbCr (black = Y'16). A client that honours the VUI (the Apple wavelet decoder reads bit 30 of word1) then skips the limited→full expansion and shows washed-out, raised blacks — reported on both Linux and Windows hosts. Patch the range bit HONEST (mark_limited_range in the shared pyrowave_wire, called by both encoders after packetize). Clients that hardcode limited (the Vulkan video_pyrowave path) are unaffected, and pyrowave's own decode ignores the flag (raw Y'CbCr reconstruction). No client rebuild needed. Unit-tested + asserted in pyrowave_win_smoke; the smoke decode still round-trips 100/180/60. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-18 11:39:44 +02:00
enricobuehlerandClaude Opus 4.8	ebd9967547	feat(pyrowave): Windows host encoder — separate-plane zero-copy D3D11→Vulkan ... Wire PyroWave into the Windows host (design/pyrowave-windows-host-zerocopy.md). Before this a macOS client + Windows host that both selected PyroWave silently ran HEVC: the host never advertised CODEC_PYROWAVE and open_video_backend bailed. Approach (zero-copy, no GPU→CPU→GPU): pyrowave owns its own Vulkan device (create_device_by_compat, by render-GPU vendor/device-id — NOT LUID, invalid in Session 0). The capturer runs a BGRA→YUV BT.709-limited CSC (matching rgb2yuv.comp) into TWO SEPARATE shareable plane textures — full-res R8 Y + half-res R8G8 CbCr — which the encoder imports into pyrowave's device. Separate single/two-component textures import reliably on NVIDIA at any size; a single planar NV12 import does NOT (the vendored interop test: "only very specific resource sizes" — confirmed on-glass: 1024² fine, 720p/1080p/1440p garbage). A shared D3D11 fence, signalled after the CSC, is imported as a Vulkan timeline semaphore so the wavelet read is ordered after it. - pf-encode: enc/windows/pyrowave.rs (Encoder impl, two-plane import + Linux-style plane views); host_wire_caps advertises CODEC_PYROWAVE on Windows when the backend isn't Software; open_video_backend routes a negotiated PyroWave session first; pyrowave-sys on the Windows target; interop confirmed at open → clean HEVC fallback. - pf-encode: shared, unit-tested enc/pyrowave_wire.rs (single source of truth for the client-facing AU framing); Linux encoder uses it too. - pf-capture: dxgi.rs BgraToYuvPlanes CSC; idd_push.rs pyrowave mode — forces the virtual display SDR (the VideoProcessor can't ingest the FP16 HDR ring), a two-plane shareable out-ring, a shared fence passed every frame (so a rebuilt encoder re-imports it). Threaded via OutputFormat::pyrowave. - pf-frame: D3d11Frame::pyro carries the CbCr plane + fence; OutputFormat::pyrowave. Verified on .173 (RTX 4090): full-host build + clippy -D warnings (nvenc,amf-qsv) + fmt --all --check; pyrowave_wire unit tests; pyrowave_win_smoke GPU test round-trips distinct Y/Cb/Cr (100/180/60) exactly at 1024²/720p/1080p/1440p; Stage-0 interop validated in the real Session-0 service context on-glass. Deployed to the box. Owed: final on-glass picture/latency confirmation. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-18 11:39:44 +02:00
enricobuehlerandClaude Opus 4.8	9a36ea2132	refactor(host/W6.2): extract the video encode backends into the pf-encode crate ... encode.rs + encode/* (NVENC, VAAPI, native AMF, AMF/QSV ffmpeg, direct-SDK NVENC/CUDA, raw Vulkan-Video, PyroWave, openh264) move into crates/pf-encode behind one Encoder trait + open_video selector (plan §W6). The crate speaks the shared frame vocabulary (pf-frame: CapturedFrame/PixelFormat + the DXGI identity D3d11Frame/make_device) and pf-zerocopy (CUDA context/buffers), and NEVER pf-capture — the capture→encode edge is one-way (ZeroCopyPolicy, prior commit). Dep moves: the heavy encoder deps (ffmpeg-next, the NVENC SDK, openh264, pyrowave-sys) move from the host to pf-encode; the host's nvenc/amf-qsv/vulkan-encode/pyrowave features now FORWARD to pf-encode/*. The host keeps a mod-encode shim (pub use pf_encode) so every crate::encode::* path (negotiator + GameStream/native/mgmt planes) is unchanged. resolve_render_adapter_luid moves from the host's windows/win_adapter.rs into pf-gpu (both pf-encode and pf-capture need it as a peer of GPU selection); its 5 call sites (encode amf/nvenc, capture idd_push/synthetic_nv12, vdisplay manager) rewire to pf_gpu::resolve_render_adapter_luid and win_adapter.rs is deleted. pf-frame's make_device gains a # Safety section (public-unsafe-fn lint, latent since the pf-frame carve — a full-workspace -D warnings clippy catches it). Verified: Linux clippy -D warnings (pf-encode + host nvenc,vulkan-encode,pyrowave --all-targets) + 13/13 pf-encode + 299/299 host tests; Windows clippy -D warnings (pf-encode nvenc,amf-qsv --all-targets + host nvenc,amf-qsv --all-targets) Finished exit 0.
