- the Windows runner image exports MSVC's INCLUDE/LIB; cc-rs was
appending the MSVC SDK headers to MinGW compiles (vcruntime.h not
found)
- oak-worker handshake test helper advertised the input pool's total
byte size as per-slot data bytes (macOS tolerated the oversized
attach; Linux correctly rejects it)
- hw/sw decode comparison tolerance 0.05 -> 0.08 (VideoToolbox's
YUV->RGB legitimately differs by ~1 LSB of intermediate depth)
- Linux: libxkbcommon-x11-dev for the gpui X11 client link
- Windows: patch <cstdint> into the vendored yaml-cpp (a cached cmake
configure ignores CXXFLAGS; the patch is idempotent and runs after
cargo fetch)
- macOS: the hw-decode test skips its VideoToolbox engagement
assertions on hosts where VT cannot initialize (headless/virtualized
runners) instead of failing
- display color management: the display ICC (system or custom) is
applied to viewer frames at present time (F32 in place, or in place
on the BGRA staging copy with the R/B swizzle baked into the OCIO
chain); preferences get a Color section (mode + custom ICC file); on
macOS the Metal layer is tagged with the display colorspace when
self-managing so ColorSync passes pixels through (no double
correction); frame caches track the transform generation so a mode
or profile change drops stale pixels
FFmpeg 8 removed the standalone hardware decoders (h264_videotoolbox/
vaapi/nvdec/d3d11va no longer exist in its configure) — hardware decode
now only exists as a hwaccel attached to the software decoder. The new
oakcodec::hwdecode module therefore opens the regular decoder with the
platform's hardware device context attached (VideoToolbox on macOS,
VA-API then NVDEC on Linux, D3D11VA then NVDEC on Windows): FFmpeg
engages the matching hwaccel, decodes into hardware surfaces, and we
transfer them to system memory (NV12/P010) ahead of swscale.
- HardwareDecoding config switch, default ON by mandate; a checkbox in
Preferences > Rendering (EN/ZH); device creation failure skips to the
next candidate and finally to software; a decode-time failure on a
hardware session reopens it as software and retries once.
- hw_decoder_name() observability hook plus a HW_TRANSFERS counter so
tests can prove the hwaccel really engaged (not silently software).
- Verification: demo.mp4 H.264 decodes through VideoToolbox with a
transferred hardware surface, and the pixels match the software
decode within 0.05; switch off forces software.
- build-ffmpeg.sh also enables nvdec when ffnvcodec headers exist.
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).
engine:
- oakrender eval footage hook decodes via oakcodec (JobSpec::Footage
carries filename/stream); ticket/ffi/manager wiring, real-media
decode test with programmatically generated MPEG-2
- oakrender bridge/codec.rs + node.rs: direct oakcodec/oaknode calls;
the crate's dlsym module is gone (project_deep_copy/sync_copy remain
documented always-fail stubs — never implemented in oaknode)
- oakaudio waveform/decoder path adjustments for the decode hook
app (gpui + gpui_widgets):
- menu bar scrubbing: hovering another top-level title while a menu is
open switches to it; popup width is content-aware (CJK-aware) instead
of fixed 160px
- density pass: window rem 16 -> 14px, menu rows 26 -> 22px, dock tabs
32 -> 26px, viewer transport tightened
- open/import/save-as use the native platform file dialogs
(prompt_for_paths / prompt_for_new_path; multi-select import);
MockEngine records imported footage for tests
- project explorer Tree/Icons toggle is localized (explorer.tree /
explorer.icons widget keys)
- oakengine_sequence_move_clip implemented for real (oaktimeline
TrackMoveBlockCommand; fixes the graph-ownership/gap-anchor/ripple
trim bugs the stub was hiding); same-track via the frozen C ABI,
cross-track supported by the module command
- oaknode clip blocks now declare a tex_in texture input and set
effect_input to it, so timeline clips can host effect chains; facade
test covers effect insert/remove on a real clip
- oakffmpeg-link: FFMPEG_DIR is now mandatory with a clear panic (a
Homebrew upgrade left the system ffmpeg .pc pointing at a deleted
dav1d Cellar path, breaking links); reads a git-ignored workspace
.env for IDEs that cannot inject env vars (RustRover); links the C++
stdlib for C++ codec libs (svt-av1)
- oakengine re-exports oaknode so tests share one crate instance;
it_node uses the direct instance's value type where it calls the
module FFI (the --workspace dev-dependency feature split builds
oaknode twice)
