- Project explorer header gains a 新建序列 button (opens the existing
new-sequence dialog, seeded like the menu action).
- Sequence presets gain 4K UHD (3840x2160@25) and 4K DCI (4096x2160@24);
the sequence-properties dialog re-selects them on reopen. Format fields
are also seedable from a probed footage format (the drop flow).
- Chroma Key (and Color Difference Key) value() now box a ShaderJobPayload
like Despill: the old OCIO-processor gate pushed nothing (the processor
is never populated without the render bridge), so the traverser handed
the clip NodeValue::None and the rendered frame lost the clip. The
renderer resolves the OCIO stub at compile time from OCIO_SHADER_STUBS.
End-to-end graph test: green key on a green frame keys out, red key
keeps it.
- The OFX color picker's SV palette / hue bar / preview / swatch canvases
get size_full(): the bare canvases collapsed to zero height in the
block layout, so the palette painted nothing (the reported 色板没显示).
Regression test clicks the palette center and expects mid s/v.
Preview now follows the project output colorspace end to end: the
display chain derives its content space from the project's OutputColorSpec
instead of a hardcoded sRGB name, self-managed ICC transforms go through
an XYZ D65 interchange stage (OCIO cie_xyz_d65_interchange) for non-sRGB
targets, and the platform layer declares the content colorspace (gpui
submodule bump). macOS defaults to OS-managed (fixes wide-gamut UI
oversaturation); Windows ACM warns once on non-sRGB targets.
Multi-monitor: the display ICC is looked up per the window's current
screen (macOS display id, Windows per-monitor DC, X11 RandR output
profile) with a throttled poll that invalidates frame caches on moves.
Pipeline precision: 10-bit+ sources fall back to YUV444P16LE + a Rust
matrix conversion when swscale lacks F32 output (no more 8-bit
truncation); BT.709/2020 SDR decodes with BT.1886 gamma 2.4 instead of
the sRGB EOTF; working-space compositing no longer clamps RGB to [0,1]
(alpha still clamped); the output node clamps to the target gamut;
frames without colorimetry metadata convert with BT.709 defaults
(warned once) instead of passing through; scopes read the
output-colorspace signal on both F32 paths.
Also: only emit rerun-if-changed for .env when it exists (a missing file
made every build fully dirty).
Match the timeline UI (V_max drawn topmost): composite tracks from
V1 up to V_max so the highest-numbered track is composited last, in
both the montage path and direct graph evaluation.
Root causes found for the 4K stalls and the second-footage memory
blowup (audit + code review):
- ticket bookkeeping leaked unbounded: the procpool ticket table and
the arena slot map only ever grew (50-100 tickets/sec during
playback, each pinning montage params and shm region views).
Completed/cancelled/superseded/crashed entries are now removed, and
the arena reaps fire-and-forget tickets once finished; the sync poll
path reaps via a terminal result() read. InFlight duplicate submits
now answer State immediately instead of sitting in the map forever.
- decode ran a full-resolution swscale to F32 RGBA (~132 MB at 4K)
plus a second full-res copy before downscaling to the 480px proxy:
RetrieveVideoParams.target_size lets swscale convert AND resize in
one pass (bilinear, matching the old Rust resampler), so a 4K
preview frame costs ~1 MB instead of ~260 MB of churn. This applies
to proxy AND full-res requests alike.
- per-process decoder cache was unbounded (each session pins an FFmpeg
context + 2 native decoded frames): LRU-capped at 16, eviction drops
the map entry (in-flight renders keep their Arc; Drop releases
FFmpeg).
- playback window completions were not generation-gated: a stale
render from before an edit landed in the rebuilt window (wrong frame
displayed, fresh request blocked). Stale completions now return
their shm slot credit instead.
- async audio prefetch used the polling ticket submit without ever
polling: switched to the fire-and-forget submit so entries reap.
All crates take the oak-* kebab-case naming (oak-audio, oak-codec,
oak-common, oak-core, oak-ffmpeg-link, oak-node, oak-otio, oak-plugin,
oak-render, oak-storage, oak-task, oak-timeline, oak-undo), with the
lib identifiers rewritten (oakrender:: -> oak_render::, oakcore_rs:: ->
oak_core::, ...) across all 226 referencing files.
The GUI application moves from the workspace root into
crates/oak-app/: src/, build.rs (paths fixed for the new location) and
tests/ travel with it, the root Cargo.toml becomes workspace-only
([workspace] + workspace.package + profiles), and the app package
inherits the workspace version. The screenshots example becomes a
standalone crate examples/simple_player/ with its own Cargo.toml.
Every crate now inherits the single workspace version
(version.workspace = true), and the workflows' crate paths and the
build docs follow the renames.
Validated with a clean cargo check --workspace.
