enricobuehler	deeb8b6700	feat(pf-encode): build against FFmpeg 9 ... ffmpeg-next 8.1.0 could not accept FFmpeg 9 at all: ffmpeg-sys-next's version probe covered avcodec majors 56..62 (the range is exclusive of its end), so libavcodec 63 fell outside what it knew how to bind. 9.0.0 widens that to 56..63, which is what actually unblocks Arch. Bump both pins — the unconditional Linux dep and the optional Windows amf-qsv one — and the lock with them. No API drift to fix. The crate major is a CEILING, not a target: one source tree still spans FFmpeg 7.x/libavcodec 61, 8.x/62 and 9.x/63 via per-version cfgs, and every wrapper symbol the NVENC-libav, VAAPI and amf-qsv backends name survives 8.1.0 -> 9.0.0 unchanged. The three hand-written #[repr(C)] hwcontext mirrors are the parts no compiler checks, so they were re-read against the real headers rather than trusted: AVCUDADeviceContext and AVD3D11VAFramesContext are byte-identical across 7.1/8/9, and AVD3D11VADeviceContext gained two trailing UINTs in 8 that 7.1 lacks — which is why that mirror deliberately stops at the common prefix, and why its assertions now say what they do and do not buy you. They pin our layout, not libav's; a green build is not evidence. The CI image is the step that makes this reach users. arch.yml deliberately runs no -Syu ("the image's snapshot IS the build environment"), so the builder stayed frozen on ffmpeg 8 no matter what Arch shipped, and a canary built from that snapshot could not satisfy the soname dep the PKGBUILD now derives. Re-keying ci/ rebuilds it against ffmpeg 9. Ubuntu and Windows deliberately stay put: the noble .deb bundles its own FFmpeg 8 behind an rpath and strips the libav sonames from its Depends, and Windows bundles BtbN DLLs into the signed installer — neither is exposed to the break, BtbN publishes no FFmpeg 9 build, and moving either would re-qualify an encode stack to buy nothing. Verified end to end on 192.168.1.21 (CachyOS, system ffmpeg 2:9.0-5, RTX 5070 Ti): host builds clean and links libavcodec.so.63/libavutil.so.61/libavfilter.so.12/libswscale.so.10 with no unresolved sonames; the ffmpeg-8 compat shim is gone and the service runs with NRestarts=0 and answers 401 on :47990; pf-encode's 67 tests pass; and a live synthetic encode drives real NVENC hardware through FFmpeg 9's libavcodec to a decodable 1080p HEVC stream (180/180 frames, FEC loopback 0 mismatches) with libavcodec.so.63 and libnvidia-encode both mapped into the encoding process.	2026-08-08 02:35:20 +02:00
enricobuehler	5c05246098	feat: M10 — FFmpeg is gone from the client ... cargo tree -p punktfunk-client-session finds no ffmpeg. The host still does, which is the whole point: pf-encode keeps libavcodec unconditionally and no host workflow, packaging script or licence file was touched. Deleted: crates/pf-ffvk, video_vulkan.rs, video_vaapi.rs, video_libav.rs, the libavcodec half of video_d3d11.rs, the av_log machinery, ffmpeg::codec::Id as the decoder's vocabulary (the quic CODEC_* wire constants now serve, which is why the evidence table was keyed on them), DecodedImage::VkFrame and ::Dmabuf, the presenter's AVVkFrame lane, and the ffmpeg-fallback feature with everything behind it. DrmFrameGuard collapses from an enum to a newtype, which removes an unsafe impl Send. Roughly 25,000 lines. Then the CI, packaging, licensing and docs work the plan's §6 lists: the Windows workflows lose FFMPEG_DIR, PF_FFVK_VULKAN_INCLUDE and their PATH prepend; the MSIX loses its DLL wildcard; the client .deb stops emitting libav sonames on its own because depends come from dpkg-shlibdeps; arch, flatpak and nix drop the dependency; and the README's "FFmpeg 7 or 8" contract narrows to the host. Three defects reached users' machines in the first cut, and none was in the deletion itself. All three desktop Settings UIs offer vulkan, vaapi and d3d11va as stored decoder values, so those strings sit in shipped settings files today. Refusing them by name — which is the correct rule for a stale pin — would have bricked every upgraded client whose owner ever touched that dropdown. They now migrate onto the native rung for the same hardware family, at decoder construction AND at each dialog's lookup, because a legacy value that matches no preset displays as "Automatic" and silently rewrites the user's preference on the next save. M9's evidence filter was deleted on the argument that with no libavcodec twin below, barring an unproven rung removes hardware decode rather than moving down one rung. That is true on Windows and false on Linux for Intel and every unknown vendor id, where prefer_vulkan_first is false and the order is native-vaapi → native-vk: a rung that has decoded nothing anywhere sitting above one that is 250/250 on three drivers. Every Intel Linux desktop would have moved from libavcodec VAAPI, shipping for years, onto pf-vaadec by default — and a rung that constructs and then produces wrong pixels leaves only by the error-streak demotion, which this codebase already documents as not tripping on the B580's strobing. The filter is restored as a narrow, pure, testable rule: an unproven rung yields to a proven one, and to nothing else. Windows deliberately passes no rung below, because that vendor family is the one with a measured wrong-pixel report against Vulkan decode, and trading no evidence for evidence of corruption is the wrong direction. And the notices still said FFmpeg was bundled. The root file is what both desktop clients include_str! and what the MSIX ships, three lines under the new card saying no FFmpeg is bundled; Apple's Acknowledgements said it too, on iOS, tvOS and macOS. The generator now emits four per-client files scoped by transitive closure — 0 FFmpeg mentions in each, verified — while the root file keeps it for the host. That also ends the standing false attribution of ffmpeg-next, GTK4, windows-rs and the NVENC SDK to an iPhone. Windows has no reachable box, so it was compiled instead: a cross clippy at -D warnings on x86_64 and aarch64-pc-windows-msvc with the C toolchain stubbed so build scripts run without linking. That gate immediately caught an include_str! path one directory too deep, which nothing else could have. Gates: container clippy -D warnings, 160 tests, workspace check, both Windows targets clean, client ffmpeg count 0 and host 2. The four decode crates are untouched, so the hardware rungs' 250/250 stands. ⚠ Owed and unrun: no GPU has executed any of this milestone. M8's on-glass software check, M7's D3D11 and VAAPI AV1 hardware legs, and M9's field bake all still want hardware, and the bake window and criteria remain the user's.	2026-08-07 08:58:47 +02:00
enricobuehlerandClaude Fable 5	a86b4c18ee	feat(ci): arch gets its builder image too — the last per-run gigabyte, and sccache through makepkg ... The arch job was the one still paying full freight every run: ~1 GB of pacman across its two install steps (never cached — container layers die with the job) and cold cargo builds (arch was skipped in the sccache rollout). punktfunk-arch-ci bakes base-devel + both makepkg legs' deps + bun + node + sccache; the in-job installs become --needed no-op guards for the one push where :latest lags. Rolling-release note in the Dockerfile: packages now build against the image's snapshot, the same staleness the gamescope cache already embraces, re-snapshotted on any ci/ edit. sccache reaches makepkg by crossing the sudo boundary explicitly — env_reset strips ambient env, so the wrapper env rides the existing `sudo -u builder env ...` list.
