enricobuehler	333f66b45b	fix(host/serverinfo): don't advertise an empty codec mask when the VAAPI probe finds nothing ... The Phase 3 GPU-aware codec mask (6922e1c) probes VAAPI on any non-NVIDIA host. On a GPU-less box (CI container: no /dev/nvidia* -> `auto` picks VAAPI, but there's no VA display) the probe returns all-false, so the mask was 0 -- the host advertised NO codecs, and the serverinfo unit test failed. Fall back to the static superset when the probe yields nothing (VAAPI wasn't usable, not "the GPU encodes nothing"); quiet ffmpeg's expected "No VA display" error during the probe; and assert the test against codec_mode_support() rather than a hardcoded 65793 so it's deterministic regardless of the build host's GPU.

enricobuehler	6922e1c467	feat(host): VAAPI codec probe + AMD/Intel packaging + neutral logs (Phase 3) ... Polish for AMD/Intel support: - GameStream serverinfo advertises only codecs the GPU can ACTUALLY encode on the VAAPI backend (probed once by opening a tiny encoder per codec). AV1 encode is narrow (Intel Arc/Xe2+, AMD RDNA3+/RDNA4) and an old iGPU may lack HEVC, so a Moonlight client never negotiates a codec the encoder can't open. NVENC/Windows keep the Moonlight-validated static mask. Validated on a Radeon 780M: h264/h265/av1 all probe true -> mask unchanged (65793). - Packaging: Recommends mesa-va-drivers + intel-media-va-driver (deb) / mesa-va-drivers + intel-media-driver (rpm) so the auto-selected VAAPI backend works out of the box on AMD/Intel; NVIDIA boxes can --no-install-recommends. (Fedora note: stock mesa-va-drivers disables HEVC/AV1 -- needs the freeworld variant from RPM Fusion.) - De-NVIDIA-fy the user-facing encoder log/context strings ("open NVENC" -> "open video encoder") now that VAAPI is a first-class backend.

enricobuehler	708c62788d	feat(host/encode): VAAPI zero-copy dmabuf import (AMD/Intel GPU CSC) ... Phase 2 of AMD/Intel support: the VAAPI encoder now takes the capture dmabuf directly and does the RGB->NV12 colour conversion on the GPU's video engine, eliminating the host-side de-pad + swscale CSC + upload the CPU path pays. - capture: a vendor-neutral FramePayload::Dmabuf (dup'd fd + fourcc/modifier/ layout). When zero-copy is on, the EGL->CUDA importer is unavailable (any non-NVIDIA host), and the backend is VAAPI, the capturer advertises LINEAR dmabuf and hands the raw buffer to the encoder instead of CPU-copying it. - encode/vaapi: the encoder self-configures from the first frame's payload (no open_video signature change). The dmabuf arm wraps the buffer as an AV_PIX_FMT_DRM_PRIME frame and pushes it through a filter graph buffer(drm_prime) -> hwmap(vaapi) -> scale_vaapi=nv12 -> buffersink; the encoder takes NV12 surfaces straight from the sink. The Phase 1 CPU-upload path is kept as the other arm (used when capture produces CPU frames). Live-validated on a Radeon 780M (real Sway/xdpw desktop capture): correct, pixel-perfect HEVC, and ~10x less host CPU at 1440p (4.2s -> 0.4s of CPU for 300 frames) -- the de-pad/CSC/upload moves to the GPU. NVIDIA unchanged (zero-copy still imports to CUDA; the passthrough path only engages on non-NVIDIA hosts). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-20 09:57:00 +00:00
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
