- The macOS SIGSEGV moved from the gl_bridge unit tests (already gated)
to other real-GL users in the same binary (suites::gl_render,
render_driver): make the gate systemic in the test build on macOS.
gl_available() reports unavailable and acquire() fails unless
OAK_GPU_TESTS is set, so every unit test takes its documented CPU
fallback; release builds are untouched.
- Dump Apple's crash reports on macOS failure: a SIGSEGV in a test binary
prints nothing, and the .ips report carries the native stack.
- The Windows-only multicam graph test failure now prints both decoded
media probes and both rendered source pixels: that separates a broken
test-media encode from a broken graph switch in one run.
- Windows: the first test executable died with STATUS_DLL_NOT_FOUND
(0xc0000135) because vcpkg's x64-windows DLLs (ffmpeg and its codecs)
were not on PATH; add vcpkg_installed/x64-windows/bin in the configure
step.
- openKylin: failure_paths_report_cleanly asserts that a read-only library
write fails, but the container runs as root, which bypasses the file
permission bits (CAP_DAC_OVERRIDE) and the write succeeds; skip that
sub-check when euid is 0 (read from /proc/self/status on Linux) and note
it in the log.
Four independent CI failures the first real cross-platform run surfaced:
- macOS SIGSEGV: the real-GL unit tests in gl_bridge ran wherever CGL is
available, including the headless CI runner. Gate them with the same
OAK_GPU_TESTS switch the integration GL tests already use (skip on CI,
opt in on a real Mac).
- Windows build: examples compile under `cargo test`, and bench_playback
used libc::getrusage unconditionally. Keep the Unix CPU accounting
behind #[cfg(unix)] and report zero CPU seconds elsewhere.
- openKylin arm64: engine_without_a_project_hits_the_guard_paths assumed
the library backend was unconfigured while a parallel config test
transiently set Storage/Backend=sqlite. Take the shared config lock and
pin the key off for the test's duration.
- openKylin x64: the prefetch smoke test asserted an exact decode count,
but the hand-off LRU holds only DECODE_LRU_CAP (2) frames, so a request
can miss the prefetched copy under scheduling pressure and re-run the
producer (the eval cache still serves the pixels). Bound the count
instead of pinning it; the deterministic sibling test pins read-ahead
usage.
Dropping a new clip whose in-point landed in empty track space (the
stored-range model allows holes between blocks; the C++ layout is
contiguous) left the overlapped clip untouched AND inserted the new clip
before it in track order, so it slid UNDER the clip it covered. Starting
on a clip already overwrote correctly, so the behavior depended on where
the in-point happened to fall.
TrackRippleRemoveAreaCommand::prepare now handles the hole case (no
block spans the range start): nothing is trimmed on the left, the
insertion anchor is the last block ending at/before the range, and the
shared trailing scan removes/head-trims the blocks the range covers.
Regression tests: domain_test (command level) and graphops (the app's
place_footage_clip path).
The macOS job finally reached the build (after the vcpkg manifest fix) and
hit a macOS-only compile error in the VideoToolbox import: `*ptr as
*const T` parses as `(*ptr) as *const T`, so `sw_format` was read off a
pointer instead of the AVHWFramesContext. Bind the frames pointer first.
Also fix the warnings the cross-check surfaced: the redundant
MTLPixelFormat import, and doc comments on an extern block and a
thread_local! (rustdoc does not document those).
Verified locally with a host-cc wrapper:
`cargo check -p oak-core -p oak-codec -p oak-node -p oak-render
-p oak-task -p oak-plugin --target aarch64-apple-darwin` is clean.
(oak-app itself needs a real Apple toolchain for ring.)
The other app test modules nest the process-wide locks language then
config; taking them the other way round could deadlock two tests running
in parallel.
On every startup (unless Preferences > General turns the new "Check for
updates" toggle off) the app GETs
https://www.oakvideoeditor.org/api/v1/update/latest, parses the
documented latest-release JSON and, when the remote version is newer
than the running build, prompts with a dialog whose primary button opens
https://www.oakvideoeditor.org/downloads. The blocking fetch runs on the
gpui background executor with a 5 s bound; transport and parse failures
are silent, and a release found while another modal is up (the project
manager on a fresh start) is deferred until the modal layer frees.
The transport sits behind an `UpdateTransport` seam so tests script the
response without touching the network; version comparison strips the
`v` prefix and pre-release suffixes and orders the components
numerically (an unparsable remote falls back to string inequality).

https://www.oakvideoeditor.org/bug-report.
The eight shipped i18n packs carry the new menu/preferences/update keys.
PanelHandle snapshots DockPanel::title at registration and the tab strip
renders that cache, so switching the UI language at runtime (the menu's
language items or the preferences combo) left every docked tab in the
previous language: the English UI with Chinese tabs from the report.
Add dock panel title/content refresh to gpui (oak-gpui 45871acf1a):
DockArea::refresh_panel_titles re-reads every held title through a
type-erased provider captured from the concrete panel entity, marks each
panel view dirty so its localized content re-renders, and repaints the
chrome. Call it from both shell language-switch paths; the preferences
dialog repaints itself too.
The app test pins the refresh end to end: after LanguageChanged the
project tab's cached title follows the new language.
The two BlockCore length setters swapped their anchors relative to the
C++ semantics they document, so the ported edit commands produced wrong
geometry on the live UI paths: roll edits kept the seam still, slides
left negative in-points, and trims wrote the timeline in-point into
media_in (playing the wrong media content).
Adopt three stored-range primitives in block.rs:
- set_length_and_media_out: in fixed, out moves, media untouched
(resize, trim-out, gaps growing rightward).
- set_length_and_media_in: in fixed, out moves, media_in += old-new
(resize-with-media-in, splice right half, ripple trim-in).
- set_length_keeping_out (new): out fixed, in moves, media_in +=
old-new (trim-in body and out-neighbour, slide out-neighbour,
ripple trim-in of the trailing block).
Point every command at the primitive matching its intent (undopointer,
undogeneral, undoripple, undosplit, graphops, cli, nodeops) and fix the
two real defects the swap hid:
- TrackReplaceBlockWithGapCommand grew a following gap rightward,
swallowing whatever followed it: the "dragging one clip moves
unrelated clips" regression. The gap now grows leftward over the
removed block's span; regression test in domain_test.
- The ripple/splice trims now advance media_in instead of rewriting it,
and BlockSplitCommand writes both halves' ranges and media
explicitly (the second half continues from the split point).
Rewrite the KNOWN-SWAP expectations to the correct geometry (roll moves
the seam, slide has no negative in-point, insert-gaps grows rightward,
resize-with-media-in yields media_in = 20) and add the missing media
assertions. TrackSlideCommand documents that the caller positions the
sliding blocks (the stored model has no track layout).
The OCIO grading primaries expose contrast/offset/exposure as Vec4 inputs
(master + RGB); build_control had no Vec4 arm, so the inspector rendered an
empty read-only row instead of controls. Add a four-spin arm bounded by the
per-component min/max and stepped by the node's base.
Float inputs that only declare base (pivot 0.18, clampBlack/White) fell
through to the wide +/-10000 default and a single drag could hurl the value
thousands of units away; anchor the slider on value +/-100*base instead,
matching the C++ RationalSlider step semantics.
Mock/real engine boundaries, shell modals and menus, timeline/
inspector/node-editor/project-explorer panels, dialogs, and the
editor controls, including the review remediation assertions.
Render evaluation fallbacks, the process pool (dispatch, cancel,
restart, teardown), half-float display packing, and the worker's
shared-memory job paths; includes the M5 footage import acceptance
tests and the software-decode byte-exactness guard.
Fixture-backed unit and contract tests for FFmpeg helpers and state
machines, OCIO color factories, wgpu backend fallbacks, and the safe
parts of the platform import module (review report section 10.2).
Adds the 90/80 coverage plan and the two-round review report, updates the
M5 backfill and plan index, moves finished plans to completed/, and
removes the machine-specific tarpaulin HTML report from the tree.
- ForceParams: hand-written Default with force_format = -1 (was 0 = U8,
which pushed the F32 pipeline into the U8 scale path).
- Plugin clip output: write CPU pixels back into the target texture
instead of the deep clone returned by texture_get_frame.
- Display ICC: probe the Debian/Ubuntu icc-profiles-free path.
- RippleInfo: public constructor and accessors so the ripple command is
reachable from integration tests.
- MockEngine: record effect-parameter and push-button attempts so the
params-view routing tests are falsifiable.
- OFX params: log rejected parameter writes instead of discarding them.
- Manager docs: state the synchronous codec-submission contract.
Adds VAAPI DMA-BUF, D3D11VA shared-handle and VideoToolbox IOSurface
imports behind a tri-state outcome (imported / unsupported / failed),
planar textures with bounded residency and a CPU staging fallback, the
staged montage decode path, reference-counted decoder frames, VAAPI-first
device selection on Linux, and the host-GPU context plumbing used by the
app and worker. See docs/zh/plans/render-pipeline-threads.md (M5).
- 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.
- Autocache range jobs now post at Background priority
(submit_video_background): they used to go through the Seek path and,
after the M4 seek over-admission, jumped ahead of playback and past the
render-queue bound. The interactive single-frame preview keeps Seek.
- Job.cancelled: the arena installs the slot's cancel atom, and
execute_job finishes a cancelled job with Error::State before running
the producer — a cancel no longer burns a full render/GPU pass only to
discard the result. Exactly-once delivery is unchanged.
- DECODE_LRU_CAP 8 -> 2: the decode service's LRU is a hand-off buffer,
not the cache of record (the eval-side decoded_frames LRU is); the
double-cache footprint at 1080p F32 drops by ~6 frames. A hand-off miss
is served from the eval cache without a new decode.
- Tests: sequence-aware preview cancel, over-admitted seek ordering,
deterministic prefetch LRU reuse, cancelled-job skip, autocache
priority. docs §3.4 backfilled with the A/B/C audit outcomes.
docs/zh/plans/render-pipeline-threads.md M4: the thread pipeline now
keeps its decode thread ahead of the render thread and the app's
playback window consumes in-process frames.
- Render queue: priority-ordered by JobSchedule.priority (Seek >
Playback > Background, FIFO within a class), so interactive frames
jump playback exports/autocache. Seek posts may over-admit the bound:
priority only reorders queued jobs, so a full queue of background work
must not park the UI thread until an export frame finishes.
- Decode queue: rendezvous Requests are served ahead of queued
Prefetches (a frame the renderer needs never waits behind speculative
decodes); Sync barriers stay FIFO. The queue is a bounded
Mutex+Condvar structure, preserving the request backpressure and the
wait_idle contract.
- Playback read-ahead: a Playback job's footage decode requests are
derived from its montage/footage spec on post (same media time, size
and force_format.unwrap_or(F32) as the eval) and queued immediately,
so frame N+1 decodes while frame N runs its GPU passes.
- App window: PreviewWindow slots are generalized to
PreviewSlot::{Shm, Video}; the pipeline's in-process TicketPayload is
cached and consumed by cpu_frame exactly like a worker slot.
PipelineBackend::preview_window_capacity reports the render-queue
headroom, so playback posts are capped to what the queue can take;
cancel_preview_frame drops queued frames the playhead has passed,
matched on the full (sequence, frame, version) key so one monitor's
window never drops the other sequence's same-numbered frame.
- Tests: decode-queue preemption/FIFO, render-queue ordering, request
derivation, and deterministic end-to-end M4 tests: a prefetch that
must be reused by the render request (LRU hit, single decode — the
read-ahead claim is falsifiable), a parked-render-thread priority test
where a full queue of background work still lets a Seek over-admit and
run first, and a sequence-aware cancel test. The playback prefetch
smoke asserts prefetches == distinct decodes == frames; it does not
claim zero heap copies (Frame.data is deep-copied at the eval-cache
and service-LRU boundaries today).
- bench_playback gains a pipeline mode with CPU (self+children) and
first-frame latency; both backends now produce F32 frames so the
comparison is like-for-like. The §3.4 backfill records the numbers:
at the proxy size the pipeline is faster with a lower first frame; at
1080p peak throughput is below the multi-worker pool, but that is an
artifact of the decode still being CPU software (M5), not a case for
pooling decode threads — GPU decode is a single device/queue and the
zero-copy import shares one GPU memory pool, so the single decode
thread stays the target shape.
docs/zh/plans/render-pipeline-threads.md M3 (design 3.2): OpenFX crash
isolation moves from "every worker hosts plugins" to a single dedicated
host process, served over NDJSON + shared memory.
- oak-worker --ofx-host mode (src/ofx_host.rs): loads every plugin once,
resolves jobs by the cross-process-stable OFX identifier, and renders
through the same in-process executor the workers used to install.
- oak-render/ofxhost.rs: the single-host client. The render manager
creates and installs it for the Pipeline backend (lazy spawn on the
first plugin job); eval::process_plugin_job prefers it and falls back
to the in-process executor otherwise, so the process backend keeps its
current behavior until M4.
- Data plane: input/output FrameSlotPool pairs (the handshake's input_*
fields are used for the first time). Named clips and the source frame
are written to input slots after the explicit CPU readback; the plugin
output returns through an output slot. Pool size/capacity grow by a
host restart when a job needs more (safe: submissions are serialized
and one job is in flight).
- Crash loop: reader EOF fails the in-flight submit, which respawns the
host and re-posts the same job (frames are read back once); after three
consecutive crashes the client is permanently dead and the evaluator
falls back to a purple frame. The dead child is reaped immediately, and
a submit mutex enforces the one-job-in-flight contract.
- Progress/cancel: the host flushes plugin_progress immediately (live
progress), and reads stdin on its own thread so plugin_cancel takes
effect mid-render at the plugin's next progressUpdate; the sticky flag
resets at progressStart and request_plugin_cancel_all broadcasts to
both the worker pool and the host.
- JobSpec::Plugin / PluginJobPayload carry the plugin type_id (stable
across processes); `--ofx-crash-once` / `--ofx-crash-always` are the
deterministic crash hooks, matching the worker's env hooks.
- Tests: wire round-trips; host unit tests (crash budget, cancel-flag
reset through the factory, source mapping); oak-worker integration
tests against the real host + bundled test plugin (render + progress,
crash respawn and re-post, three-crash give-up, mid-render cancel on
the new slow variant, concurrent submits); eval's purple fallback.
- Windows: vcpkg ships `pkgconf` without the `pkg-config` shim, so the
oak-ffmpeg-link build script failed with "program not found". Probe
`pkg-config`, fall back to `pkgconf` (or honor `PKG_CONFIG`), and join
the child's `PKG_CONFIG_PATH` with the platform separator instead of a
hard-coded `:` (which split `C:\...` apart).
- Linux (and openKylin): the test binaries link the VAAPI stack via
vcpkg's FFmpeg; install the `libva2`/`libva-drm2`/`libvdpau1` runtime
packages the loader needs.
- macOS: bump the gpui submodule
(OakVideoEditorCommunity/oak-gpui@fix/macos-metal-layer-and-dead-code):
`setColorspace:` now sends to the `MetalLayerRef` (`self.layer.as_ref()`
made `&*layer` the owned type, which is not `objc::Message`), and the
viewer's `GpuFrameEntry` carries the non-Linux dead-code allowance.
- openKylin ARM64: switch the ocio patch to the fork's
fix/aarch64-c-char rev. Upstream models C `char*` as `*const i8`;
aarch64's `c_char` is u8, so the crates did not compile. The fix uses
`c_char` throughout ocio-sys and the ocio-rs boundary (pushed as
30338c6a169bbbada862fb3ac256e79b656159cf).
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.
docs/zh/plans/render-pipeline-threads.md M1: an in-process
alternative to the worker-process pool, behind OAK_PIPELINE=threads
(processes stays the default and is fully retained).
- pipeline.rs: PipelineBackend implements JobDispatch over a single
render thread draining a bounded FIFO (cap 8; blocking post with
condvar backpressure and a one-ahead exception for re-posts from
the render thread itself; shutdown drains with Error::State like
the inline dispatcher). The DecodeService is a single decode
thread behind a bounded command queue with a real LRU (tick-based
eviction), rendezvous requests (None on shutdown -> the caller
decodes inline), prefetch gated on render-queue room, and a Sync
barrier; it installs into a process-wide slot that eval's footage
path consults per frame (no service -> the synchronous decode it
always was).
- The manager gains RenderBackendChoice::Pipeline; init() reads
OAK_PIPELINE (threads -> pipeline, anything else -> the process
pool), audio stays deliberately inline.
- Present mapping: the UI thread consumes through the ticket
completion, unchanged — no fourth thread is invented.
- Tests: decode-service unit tests (rendezvous, LRU hit/eviction,
error propagation, backpressure gate) plus a six-case integration
suite matrixed over inline vs pipeline — consecutive-frame and
out-of-order seek pixel equality asserted byte for byte, with
decode counters proving the service (not the caller) did the
codec work.
The 8.1.0 downgrade broke the build and the audio export: 8.1.0's
typed video encoder has no set_color_primaries /
set_color_transfer_characteristic, and its older audio path sent
near-NaN samples into the AAC encoder (transcode_mp4 and the oak-task
export test both failed). ffmpeg-next 9.0.0 supports ffmpeg_8_0/8_1
(the vcpkg pin of 8.1.2#3 is unaffected) and carries ffmpeg_9_0 cfg
branches for the day FFmpeg 9 lands.
254 warnings (320 counting replayed-cache re-emitters) cleaned:
unused mut/imports/variables, irrefutable if-lets and unreachable
patterns, dead code removed or annotated #[allow(dead_code)] with
the reason (C++ parity value sets, cfg(test) helpers, public API
reservations), drop(&ref) no-ops removed, fn-pointer identity via
std::ptr::fn_addr_eq, the test-stubs feature declared in
oak-node's manifest, missing docs filled. Every unused-Result site
was judged individually: meaningful errors propagate, intentional
ignores are let _ = with a note.
Two pre-existing latent bugs are documented in place, behavior
preserved: app.rs's timeline-tool observer and dialogs.rs's format
subscription both drop the returned Subscription immediately, so
they never fire.
macOS has no posix_fallocate (and the libc crate rightly does not
expose it there), so the shm segment setup failed to compile. The
eager reservation is a tmpfs concern; off Linux the call is skipped
and the existing touch-every-page fallback runs instead.
The GraphInput/GraphOutput cards render through the same build path
as every other node (real graph data, fixed header accents outside
both palettes), GraphOutput as a pure sink with no output ports.
UI-layer protection keeps the pair fixed: the context menu drops the
whole edit section (cut/copy/paste/duplicate/rename/delete) for
them, and delete requests naming an endpoint are narrowed at the
panel — the endpoints and the wires hanging off them always stay,
a request left with nothing is dropped whole. The engine reports the
protected set through AppEngine::protected_graph_nodes (the real
engine resolves Graph::endpoints; the mock demo graph carries its
own marked pair).
Per docs/zh/plans/render-pipeline-threads.md §3.8:
- oak-node/nodes/graphendpoints.rs: the GraphInput/GraphOutput
virtual node pair — factory-registered but hidden from every create
menu, duplicate refused, real value() semantics (the input forwards
its feed_in row, the output publishes its tex_in as the frame).
The input endpoint also declares a connectable feed_in port
(documented deviation: footage/generator sources have no connectable
inputs, so the walk needs a feeder anchor).
- graph.rs: ensure_endpoints/endpoints/is_endpoint — idempotent,
identified by type id, default input->output edge only while the
output's tex_in is free; remove_node refuses endpoints.
- project.rs + serializer.rs: every project graph carries the pair;
a legacy file without endpoints migrates on load (roundtrip and
legacy-migration tests, re-save is idempotent).
- traverser.rs: eval_graph_bfs — the endpoint-to-endpoint Kahn
sweep. Live set = (input's forward cone U its feeder cone) INTERSECT
(output's backward cone); multi-input nodes dequeue at zero
in-degree over the live subgraph; deterministic ascending-id ready
order (Graph::edges is a BTreeSet, so insertion order is
unrecoverable — documented); time-shifted upstreams pull through
the shared DFS memo (walk_dfs, factored out of evaluate);
un-orderable remainder reports a named cycle; missing endpoints /
unreachable output are errors. Eight BFS tests cover the plan's
acceptance bullets.
- oak-render: bfs_endpoint_sweep_renders_footage_through_position —
real clip through a real Position node via the sweep, shifted
pixels asserted against a reference decode.
- Endpoint names localized in all eight i18n packs; storage/structure
tests updated for the two extra nodes.
M0a of the render-pipeline plan (docs/zh/plans/render-pipeline-threads.md):
- oak-node: every payload push site (58 across footage.rs, plugin.rs
and the nodes/* effects) now boxes the Job enum instead of the raw
payload. The enum gains CacheJob with a CacheJobPayload (path +
time + fallback value, the C++ cachejob.h shape), plus safe as_*
accessors and unsafe probe helpers beside job_ref.
- oak-render: RenderEvalHooks::resolve is one loop over the table —
a single get_checked::<Job> probe per texture value, a match
dispatch to process_footage/shader/plugin/color_transform/cache,
and recursive resolution of the job boxes embedded in a payload's
inputs (depth-capped, cycle-guarded) — replacing the four
sequential full-table scans (resolve_*_jobs, deleted).
- The disk frame cache is real: frameio.rs implements a minimal
self-describing F32 container (magic/version/dims/format/timestamp
+ payload, tmp-write + atomic rename, full header validation on
load) because the OIIO bridge is a stub and EXR is unavailable in
this build; process_cache_job genuinely reads the file before
falling back to the job's (already resolved) fallback value.
- Tests: CacheJob roundtrip (save -> resolve -> pixel equality),
missing-file fallback, nested cache-job-through-shader resolution,
plus four frameio container tests. 2330 passed, 0 failed across
the workspace.
The off-frame mask edit redeclared vec2 uv inside main(); naga's GLSL
frontend rejects the redeclaration, so the swirl shader failed to
translate for wgpu.
A clip drag moved only the clip under the cursor (plus its graph-linked
A/V partner); the rest of the selection stayed behind. The engine now
keeps the full timeline selection (it used to collapse it to the
effect-stack's single target) and expands ClipMoveRequested to the
grabbed clip's transitive link group UNION, when the grabbed clip is
part of the multi-selection, every other selected clip and their link
groups. Each follower stays on its own track and shifts by the same
frame delta (relative positions preserved), the group-wide clamp keeps
every clip at or after frame 0, and the whole move is one undoable
entry. Followers on locked tracks are left in place.
moving_a_multi_selection_drags_the_whole_group covers two A/V pairs:
selecting both video clips and dragging one moves all four clips by
the same delta, and one undo restores them.
Dropping a transition on the timeline failed with "the track has no
frame rate": drop_transition_at asked sequence_time_base for the TRACK
node, but the frame rate lives on the sequence (tracks carry no video
params, so the lookup always returned None).
With that fixed the drop deadlocked instead: the edge resolution ran
while holding the project lock, and the add_transition_at_seam/edge
builders lock the project internally. The function now plans under the
lock and executes after it is released.
Covered by engine_drops_a_transition_at_a_clip_edge: a head-edge drop
with no previous clip lands a single-sided transition wired into the
clip only.
Generator effects (bars, checkerboard) can be dragged from the library
onto the timeline, where they land as a standalone five-second clip
built from the node factory; the inspector shows the generator's
parameters as the clip's own chain.
Transitions are no longer junction-only. The render planner accepts a
transition with at least one wired neighbor and blends the missing
side against transparent black, so head transitions fade in from black
and tail transitions fade out to black. add_transition_at_edge creates
those single-sided blocks (wired to just the IN or OUT block), the
default-transition command covers both ends of a lone clip, and an
effect drag dropped near a clip edge routes to the nearest seam or
edge within a one-second window.
Translating, rotating or warping content past the frame edge used to
smear the clamped edge row/column across the vacated region. The
transform, position, swirl, ripple and wave shaders now multiply the
sample by an in-bounds mask so off-frame pixels come out transparent
(and composite as black when nothing sits below). Tile deliberately
keeps its wrapping lookup.
Typing in a text input fired the global key bindings (space toggled
playback, Delete removed clips, ...). Every non-multicam binding now
carries a !EditableText context predicate so the app's own bindings
stay inactive while an editable text element has focus.
Predicate-gated bindings never match on an empty context stack, and
the app shell had no root key context — so the root element now sets
key_context("OakApp") to keep the dispatch stack non-empty
everywhere outside the panels.
The render worker process never installed a text backend, so text clips
rendered as empty frames in playback and export. The cosmic-text engine
now lives in oak-render (the crate both the app and the worker link),
and the worker installs it during runtime initialization.
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.
Text is no longer a hand-written HTML effect (docs in
docs/zh/plans/text-footage-redesign.md):
- textv3 gains structured inputs - plain text, font family/size, font
color, outline (enable/color/width), glow (enable/color/radius); the
legacy text_in HTML is hidden and auto-migrated to plain text on load.
- Outline and glow render as GPU post-process chains (dilate/blur +
colorize under the text); the font color tints the raster
premultiplied. Plain text now rasterizes even with both passes off
(previously a null deferred job), fixing a use-after-free where the
handle was lifted out of an owning Option<NodeValue> before addref.
- A cosmic-text backend (the lockfile's 0.19) installs at engine
startup through the textbackend hooks and feeds the font-family combo.
- The project panel gains 添加文本素材 next to 新建序列: a text entry
in the bin that drops onto the timeline as a clip (one undo row), its
parameters shown as structured fields in the inspector (multiline
text area, no HTML anywhere). text3 is hidden from the effect add
menus; legacy text3 chains keep evaluating.
21 built-in effects reimplemented as native GPU nodes from the
OpenFX-Misc algorithm references (cleanroom, docs in
docs/zh/plans/ofx-misc-gpu-cleanroom.md):
- Color: Color Correct, Gamma, Saturation, Invert, Clamp, Grade
- Matrix/morphology: Color Matrix, Edge Detect, Dilate, Erode
- Blur: Directional Blur, Sharpen (unsharp mask)
- Merge: Dissolve, Key Mix, Premultiply, Unpremultiply
- Geometry/generators: Position, Mirror, Checkerboard, Color Bars, Ramp
Every node carries unit tests plus GPU pixel tests (28 cases over five
ofxmisc_* suites). The effect library groups built-ins by category
(color/filter/distort/keying/generator/math/general) with collapsible
group headers persisted to the config; the inspector's add menu groups
the same way. Registration wiring and the factory smoke table land with
the adjustment/transition wave sharing the same files.
The params view reapplies the engine snapshot to every control on each
render (every engine tick), which wiped the in-progress text a frame
after each keystroke - the text effect's field was effectively
untypeable. Skip the re-sync while the field is focused (the same
guard the curve editor has for drags); it re-syncs on blur and the
row's explicit commit writes the edit back. MockEngine gains a
sentinel text parameter for the regression test.
Edits invalidated the display caches, but the debounced snapshot
upload (150 ms) landed later - meanwhile the viewer had already
rendered and cached a proxy through the stale snapshot, and nothing
invalidated it again, so a paused monitor kept the pre-edit picture
until the playhead moved. Re-invalidate when the fresh snapshot is
actually installed so the next paint re-renders from it.
The transform shader sampled in a top-left-origin pixel space while
Olive's transform semantics (and every other node) are center-origin:
rotation swung the image around the top-left corner, pushing it partly
off-frame - reading exactly like an unwanted zoom. Match the C++
transform.vert projection: position (0,0) is the frame center and
rotation/scale pivot around the anchor, so rotation and scale stay
independent user controls. GPU tests pin the 90-degree landing spot
(no smearing) and the 2x scale centroid (stays centered).
- available_range declared a zero duration for every clip (the media
was 'unusable', so Resolve invalidated all of them): it now covers
the whole media - video clips in the probed frame rate, audio clips
in the probed sample rate (no more hardcoded 48000/0).
- Gap ranges mixed time bases (a 24 fps block start, a 1.0 trailing
duration): gaps now stay in the sequence's time base, the trailing
pad in whole frames.
- Empty sequences (no clips) are skipped, so a lone edited sequence
exports as a bare Timeline root instead of a SerializableCollection
Resolve cannot read.
- FCPXML: an asset used on both video and audio tracks now declares
hasVideo AND hasAudio (the first registration's track kind used to
hide the other stream); asset durations recover with available_range.
- Runtime window icon: X11 takes the embedded 512px PNG up front
(_NET_WM_ICON), Wayland resolves it from oak.desktop via the app id,
Windows reads it from the exe's icon resource.
- assets/appicon: 512px PNG + 7-size ICO rasterized from Oak_Icon.svg.
- Windows: oak.rc (ICON resource ID 1, also the Explorer icon) compiled
by build.rs through embed-resource.
- Linux packaging (deb/rpm/PKGBUILD/oak.spec): install Oak_Icon.svg
into the hicolor scalable theme alongside the existing 512px PNG.
- macOS: no change needed - cargo packager already builds the .icns
from the CD-generated icons/icon.png (same source art).
Two export killers fixed and the feature surfaced properly:
- TicketArena::allocate() reaps finished fire-and-forget slots on every
new submit, but RenderTask classified finished tickets by asking the
arena for their kind/time afterwards - any ticket that completed
before the next submit (all of them on the inline backend) failed
with 'Render ticket reported an unexpected timestamp' and the export
died after writing a header-only file. RenderTask now records each
ticket's delivery key at submit time instead.
- File > Export becomes 导出序列 (all 8 locales): the dialog offers a
sequence picker (any sequence in the project, the current one
preselected) instead of silently exporting the current one, and the
project bin's sequence context menu gains 导出序列 opening the same
dialog. Engines expose sequence_entries / current_sequence_id /
start_export_of.
- The export-project dialog drops its dead hand-typed path field (OK
already asked the platform save dialog).
- New end-to-end test: a one-second sequence exports to a real
H.264/AAC MP4 that probes and decodes back to the clip's content.
Preview renders at proxy size while a paused frame renders full-res, so
anchoring resolution_in to the render target made every sequence-pixel
effect (shape size/pos, transform offsets, corner pin points, drop
shadow distance) change apparent size whenever the transport stopped.
Pre-fill resolution_in from the sequence's video params (C++ inserts
the NodeGlobals square resolution at job-build time), covering the
nested generator job inside a merge as well; a node that inserted its
own resolution_in keeps it.
The sampled pixel lands (disarming the eyedropper) between the button
going down on the program viewer and coming back up, so the trailing
mouse-up read as an outside click: the popup closed and close_menu
discarded the just-picked draft - pick-from-viewer could never be
confirmed. Swallow the pick's own mouse-up once; a later genuine
outside click still dismisses.
