vcpkg resolves the ffmpeg dependency before anything builds and rejects
the manifest because the pinned 8.1.2#3 port has no `png` feature
("ffmpeg@8.1.2#3 does not have required feature png needed by oak"),
so every desktop job died in "Install dependencies (vcpkg manifest)"
and never reached the build or test steps.
PNG decoding in FFmpeg needs zlib (png_decoder_deps=zlib); libpng is
only the encoder backend and this port never enables it. Request
`zlib` instead.
Also point the stale comments/docs at the actual pin: the override is
8.1.2#3 (matching the ffmpeg-next 8.x binding after the 9.0.0 binding
was found broken upstream), not 9.0.1#1.
Three independent failures from the last run:
- Linux undefined `vaMapBuffer2`: the runner had apt libva 2.20 while
vcpkg builds shared libva 2.24.1, and the loader had no path to it.
Drop the apt libva packages and put `$prefix/lib` on LD_LIBRARY_PATH
for the Linux and openKylin jobs.
- openKylin "render manager failed to start": a container's /dev/shm is
64 MiB, but the process pool reserves >64 MiB per worker with
posix_fallocate, so segment creation fails. Run the container with
`--shm-size=2g`.
- macOS "no decoder for codec PNG": the vcpkg ffmpeg manifest never
enabled the `png` feature the oak-cli transcode tests need. Add it.
- Windows dependency install took 41 minutes: it was rebuilding FFmpeg
and every codec port from source because the binary archive cache was
never saved. The combined `actions/cache` step with the deprecated
`save-always: true` does not save after a failed job, and the previous
run failed in Build. Replace it in all four jobs with an explicit
restore + `actions/cache/save (if: always() && cache-hit != 'true')`.
- vcpkg bootstrapped in every job (the Warp runners carry none):
clone + bootstrap into .cache/vcpkg, VCPKG_ROOT exported.
- vcpkg.json: ffmpeg pinned at 9.0.1#1 via overrides with
builtin-baseline 771b0a2e pinning the port tree; feature fixes
(gnutls -> openssl, ffnvcodec -> platform-qualified nvcodec,
vaapi on Linux, librsvg windows-only).
- Linux and macOS CI/CD jobs also take FFmpeg from the manifest
(static triplets x64-linux / arm64-osx keep the packaging story);
the build-ffmpeg.sh steps, FFmpeg caches and the codec dev
packages leave the workflows — system package managers keep only
the X11/audio/GL/Vulkan/tooling deps, now documented in
docs/build.md.
- New openKylin container job (openkylin/openkylin:latest) on x64
(warp-ubuntu-latest-x64-8x) and ARM64
(warp-ubuntu-latest-arm64-16x, arm64-linux triplet): openKylin
package names surveyed against the live image's apt index
(nasm/zip come from the kylinsoft anything3.0 PPA), clang for
bindgen, xvfb + lavapipe headless tests with the watchdog and
retry policy.
Known follow-ups (declared in the commit chain): vcpkg has not run
end-to-end yet, the pkg-config vs pkgconf executable name on
Windows, TLS semantics moving gnutls -> openssl.
The MinGW path kept fighting the environment (the GitHub image's
MSVC INCLUDE/LIB poison the GNU compiles; ocio-sys' fork then
dragged the MSVC-only headers into g++ and died on vcruntime.h).
The Windows jobs on both workflows now:
- run on warp-windows-2025-vs2026-x64-16x (preinstalled VS 2026)
with the stable MSVC Rust toolchain;
- install dependencies through vcpkg MANIFEST mode: vcpkg.json at
the repo root carries FFmpeg with every free codec + hwaccel
(mirroring build-ffmpeg.sh's configure), pkgconf and librsvg;
the vcpkg_installed tree plus the binary-cache archives are
cached on the manifest hash with save-always;
- build OCIO bundled (ocio-sys' vendored sources are what MSVC
wants — the MSYS2 package was the workaround, not the
preference), so OCIO_RS_NO_MSVC_INCLUDES is gone;
- ship the vcpkg runtime DLLs next to the binaries in the NSIS
installer with a static-CRT release build (no vcruntime DLLs),
replacing the ntldd-based MSYS2 bundling.
FFmpeg version pinning via builtin-baseline is a documented
follow-up: the Configure step logs vcpkg list so the first green
run reports the resolved versions. docs/build.md keeps the MSYS2
flow as the local alternative and points at the CI path.
- Update CI badge URL to OakVideoEditorCommunity in README.
- Remove outdated TODO files, vcpkg.json, patch file and stale log.
- Clean up obsolete docs and move ofx-pluginrenderer-functions-zh.md
into docs/zh/.
