Single-lib cleanup: the per-crate src/bridge/ and src/ffi.rs layers are
gone (oakundo/oakcommon/oaknode/oaktimeline/oakcodec/oakaudio/
oakrender/oaktask/oakplugin/oakstorage); cross-crate calls are plain
Rust, CHandle marshalling shrinks to the oakengine boundary, and tests
call the Rust APIs directly (pure C-ABI wrapper tests removed where
the domain layer already covers the behavior).
exporter.h family implemented: oakengine_export_render (CLI contract),
oakengine_export_render_with_params (was a stub), last_error and
progress callback; synchronous path reuses task_create_export +
start_sync. Fixes on the way: oaktask video ticket self-deadlock,
audio params dropped on the export path, codec encoder AAC slicing and
H.264 time base. Real-mp4 tests cover both entry points, progress and
the illegal-argument matrix.
Also: oakstorage session maps null project handles to None (version-
info path), configstore test double literal 3.14 -> 3.15 (clippy PI
lint), oakaudio output callback scratch buffer + env-aware P1 test,
cli media round-trip test uses a generated 16-frame clip (no more
minute-long debug runs).
- tooling/ffmpeg/build-ffmpeg.sh builds release/8.0 static+PIC into
.cache/ffmpeg: GPL/version3, every free-license external codec lib
probed via pkg-config (enabled when present), per-OS hardware
acceleration (VideoToolbox/AudioToolbox, VAAPI/VDPAU/libdrm,
D3D11VA/DXVA2/MediaFoundation, nvenc when ffnvcodec exists)
- tooling/install-deps.sh installs those libraries on Homebrew / MSYS2
UCRT64 / Debian-Ubuntu / Fedora / Arch; nothing in the build sudo's
- ffmpeg-next's own build feature is unusable (every crate-version to
FFmpeg-release pairing is broken upstream: 9.0.0->FF9 AVCodec fields,
8.1.0->FF8.1 new enum variants, 8.0.0->FF8 FF_PROFILE rename), so
ffmpeg-next 9 + FFmpeg 8.x headers via FFMPEG_DIR it is
- new links-crate oakffmpeg-link emits the static FFmpeg's transitive
link flags from its .pc files (cargo only propagates them from links
crates, and rustc prunes the flags unless the rlib is referenced —
hence the force_link statics)
- docs/build.md updated for the Rust workspace flow
