- Mark the raw-pointer interop entry points unsafe with # Safety docs
(oak-core upload/download/frame-from-pixels, oak-audio convert) and
satisfy the existing callers (tests).
- mut_from_ref: allow with the ABI contract documented (the handle
get_mut helpers in oak-timeline/oak-render/oak-task take the shared
reference the C ABI passes; exclusivity is the caller's unsafe
contract).
- Fix the eq_op in the white-balance normalization (green / green).
- Apply cargo clippy --fix across the workspace (redundant closures and
field names, field reassignment, items after test modules, ...).
- Revert the replace_box fix in image_effect's clip_define: a
redefinition must allocate a new box, otherwise the old clip handle
stays valid and the HS-map replace contract (clip != clip2) breaks.
- 283 warnings remain; they are all non-machine-applicable
(chunks_exact -> as_chunks needs a manual iter_mut, too_many_arguments,
complex types, missing Safety docs, ...) and are tracked as the
follow-up.
docs/zh/plans/render-pipeline-threads.md M2: the graph's textures stay
on the GPU from evaluation through presentation, and presentation runs
on the UI's own wgpu device.
- wgpu 25 -> 29 (naga 29) across the engine, unifying it with
gpui_wgpu so engine textures are directly sampleable by the presenter
(a single wgpu remains in the lockfile).
- GpuContext::adopt/install_shared: the app registers the window's
device at startup and the render thread renders on it;
texture_handle hands the raw Arc<wgpu::Texture> to
SurfaceSource::Texture - zero-copy present on Linux/FreeBSD. The
shared slot replaces an engine context that has not touched the GPU
yet (startup-order guard) and refuses once it has.
- Texture::Gpu shares a GpuLease so clones release the registry token
exactly once; the compositor, transitions and adjustment sweeps keep
GPU textures end to end (no per-clip readbacks; GPU clears for
black/generated frames).
- Color management stays on the GPU: the output node + display ICC
chain is baked into a 65^3 3D LUT with the exact CPU reference and
applied by the present WGSL pass (manual trilinear);
ColorTransformJob bakes its OCIO processor the same way. Neither
path skips color management.
- The explicit readback boundaries accept GPU textures: export
encoder, CLI, worker shm, disk cache; CPU OpenFX already read back.
- M5 dependency: the YUV->RGB GPU pass (BT.601/709/2020 x
limited/full) matches colormath::yuv444p16_to_rgb_f32.
- Acceptance: gpu_transfer_counters; single-clip and layered
(multi-track + transition + adjustment) playback tests assert zero
GPU->CPU readbacks, and the app test asserts adopted-device present
is zero-copy. GPU tests hard-fail when OAK_REQUIRE_GPU is set (CI
lavapipe) instead of skipping silently.
Adjustment layers (docs/zh/plans/adjustment-layers-and-transitions.md):
a new timeline block type whose effect chain grades the composite of
every video track below it, over its own range (spanning clips or a
slice of one). The graph path flushes the lower tracks at the block's
track boundary and sweeps the composite through the chain via a
transient texture-source node; the montage path mirrors it with
AdjustmentSpan tickets (wire-compatible), so worker previews and
exports agree. An empty-area context menu creates one; the block
trims/moves/deletes like a clip, with undo everywhere.
Transitions: seam blocks come alive - cross dissolve/fade/wipe/slide
evaluate both neighbors through the graph path with progress from the
transition's own range (never the whole clip). Ctrl+Shift+D or the clip
menu inserts a default transition; the gpui wedges render and drag to
resize offsets undoably, and TransitionRemoveCommand now restores
offsets and edges on undo. The transitionfx node form runs the same
shaders on an adjustment layer with progress_in auto-filled from the
layer's span (explicit value wins).
Also: every built-in effect name and parameter name is now
translatable (360 node.* keys per locale, zh-CN fully translated, two
coverage tests guard future gaps); the new nodes register in
nodes/mod.rs with the factory smoke table updated; textfootage and
adjustment-layer i18n keys included.
