`cargo fmt` was not run on the Phase 5.2 additions (nvenc_cuda.rs + the encode.rs dispatcher fork), failing the ci.yml rust fmt job. Whitespace/wrapping only — no behavior change. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

Phase 5.2 of design/encoder-recovery-hardening.md (design/linux-direct-nvenc.md). The Linux NVIDIA host encodes through libavcodec `hevc_nvenc`, which structurally cannot express `nvEncInvalidateRefFrames` — so every FEC-unrecoverable loss is a full IDR and, since the client freezes-until-reanchor, a per-loss freeze for RTT+IDR-encode. This ports the Windows raw-NVENC backend to NV_ENC_DEVICE_TYPE_CUDA over the shared CUcontext so Linux NVIDIA gets the same real RFI + F2 recovery-anchor + reset() stall lever + HDR-SEI/Main10 plumbing. New `encode/linux/nvenc_cuda.rs` (`NvencCudaEncoder`): - runtime-loaded entry table via `dlopen libnvidia-encode.so.1` (never link-time, mirroring the zerocopy::cuda libcuda loader) — one binary still starts on AMD/Intel Linux boxes and falls through to VAAPI/software; - session on the shared CUcontext (zerocopy::cuda::context()); - an encoder-owned ring of registered CUDADEVICEPTR input surfaces (zerocopy::cuda::InputSurface + a contiguous-NV12 allocator), each captured DeviceBuffer device→device copied in via the existing copy_* helpers — mirrors the libav recycled-hwframe-pool copy, so zero regression vs today; - config/RFI/anchor/reset ported from the Windows backend; sync-only (NVENC async is Windows-only, so that whole subsystem is dropped); - Main10/HDR-SEI wired but inert until a Linux P010 capture path (Phase 5.1). Wired behind PUNKTFUNK_NVENC_DIRECT (default OFF) in open_nvenc_probed; the Windows path is untouched (no shared extraction in v1). Two on-hardware `#[ignore]` smokes added. Validated on .21 (RTX 5070 Ti, driver 610.43.03): builds on Linux under ci-check, clippy-clean, full host suite 272/0, NV12 smoke (8 AUs, real invalidate_ref_frames + recovery_anchor on a P-frame) and YUV444 FREXT smoke (6 AUs, chroma_444) green; Windows compile unaffected. Owed: the client-in-the-loop matrix (RFI-survives-ABR, reset() heal, A/B vs libav) and the default flip. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
