- viewers show the 480px proxy immediately and a background thread
fills the sequence-resolution frame (per-monitor in-flight job,
generation-based staleness, playback skips full-res)
- preferences dialog complete: cache dir (now consumed by
default_disk_cache_path), proxy policy/divider, snapshot interval
(write-through era autosave), default transition length, audio
in/out devices (new facade device-enumeration exports; audio init
from config — playback was never creating the audio instance),
language/theme/renderer backend, all persisted via config
- shortcut map (src/shortcuts.rs): space/J/K/L, I/O, S split, A/^A,
⌘Z/⌘⇧Z, ⌘N/⌘O/⌘S/⌘E/⌘Q, frame step, Home, track zoom; dispatch
shares the menu action path and stays silent over modals
- screenshots: preferences dialog zh/en captured and reviewed
D3: oakdb+pg:// fully wired (shared sea-orm entities, BIGSERIAL DDL,
connect-probe instead of pool retry on dead servers); Storage/Backend=pg
+ Storage/PgUrl config; 13 OAK_TEST_PG_URL-gated PG tests (verified
against a Docker postgres:16), always-on clean-error tests otherwise.
D4: DaVinci-style project manager — list with derived stats, create/
rename/duplicate/delete (confirm)/import/export (native dialogs,
ove/otio/fcpxml), shown at startup and from the file menu; facade
oakengine_library_* exports (list/create/delete/rename/duplicate/
import/export + project_load_library that binds write-through);
save/save-as menu becomes 'export project file', open splits into
from-library/from-file; status bar shows library write state; storage
activates on app start and flushes on exit; spawn_modal reentrancy
fixed (window-callback path) with a doc note.
Also: the P1 audio test's environment probe was lost in the ffi purge;
restored on cpal (the output device is cpal now).
- facade storage session manager: project handles bind to the default
SQLite library on project_new/load; every undo push/group_end/jump
write-throughs via DatabaseBackend::save (diff journal); project_free
flushes and unbinds
- background snapshot thread (Storage/SnapshotIntervalSec, latest-wins,
newest 3 kept) with exit flush (oakengine_storage_flush)
- config-gated: storage only activates with an explicit
Storage/Backend=sqlite, so headless consumers and tests never touch
the real library; new exports: storage_flush/is_bound/last_error
- it_storage: kill -9 recovery, cross-session undo, snapshot pruning,
multi-project isolation, graceful degradation
- also fixes a real config test polluting the user config.ini and the
undo-stack test races
oakstorage (new workspace member): URI dispatch, pluggable backends
(ove-xml built in, otio/fcpxml via oakotio, C-vtable foreign
registration), the M10 C API surface, version info codes, last-error
and alive accounting; round-trip tests per backend.
oaknode serializer: persists the full timeline — sequence track lists,
track block lists, block ranges/media_in/speed/flags, clip footage
references, footage filename+streams, folder children — through
<custom> behavior hooks with two-phase reference resolution; loads the
C++ <olive><project><layout> containers (golden: tests/
project_with_footage.ove); round-trip is field-by-field and
byte-idempotent.
- screenshot example inits i18n and captures both zh-CN and en-US
(docs/screenshot-window{,-en}.png)
- dock tabs size to content (no more 64px truncation); viewer/panel
titles follow the design (素材查看器·name etc.)
- mock project carries V1/V2 video + A1/A2 audio clips rendered as
rounded green bars; timeline clip geometry/rounded corners match the
design; status bar visible with full content; audio meter strip
docked at the program viewer's right edge; project explorer rows
have icons
- tests/waveform_e2e.rs: waveform cache extracts real peaks and hits
cache on re-query (P4 acceptance)
- 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)
- 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
- App no longer depends on the oakengine rlib: build.rs links the
built liboakengine.dylib (+rpath, -export_dynamic, IOSurface) and
src/oakui/ffi.rs declares the pure-C surface; RealEngine calls only
the frozen oakengine_* C ABI
- host_syms.rs provides the oakcore_*/fb_* host symbols the dylib
imports via dynamic lookup
- Fix Preferences dialog crash (spawn_modal reentrancy) with a
regression test
- Timeline toolbar and viewer transport render C++-era icons (16px
grid, dark/light themes) with localized tooltips
- i18n: complete en-US table, add untranslated-key detection test
- New dialogs module (preferences, export, progress)
- oakcore-rs: Rational/TimeRange/TimeRangeList/PixelFormat/SampleFormat
mirroring oakcore C++ semantics (91.6% coverage)
- oakundo: UndoCommand/UndoStack with vtable commands (99.6%)
- oakcommon: config/XML/VideoParams/logging etc. (89.8%, 516 tests);
XML via quick-xml, logging via the log facade
- oaktimeline: markers/workarea/edit commands (95.4%)
- oakaudio: processor/manager/sync/waveform/levelmeter (88.4%)
- unified -MMCCCC error codes across all C ABI headers (registry in
include/common/error.h; pass-through rule)
- olive::Variant moved node -> common (cross-module value type)
- oakcommon_videoparams_set_is_3d added to the C ABI
- M11 (oakplugin Rust rewrite) plan + notes.md freeze line for the
inter-module C ABI wiring
- oakrender cache C API: add create_for_node (four cache kinds),
get_uuid, request, load/save_state, set_saving_enabled,
set_passthrough, get_passthroughs, get_valid_cache_filename,
get_timebase, lock/unlock, invalidate_range (rational variant),
get_native (C++ only, for the in-module PreviewAutoCacher)
- Node's four caches become owned OakRenderCache value handles; all
cache access in node.cpp/clip/viewer/traverser/serializers goes
through the C ABI
- oaknode_node_get_video_frame_cache returns an addref'd
OakRenderCache; drop OakNodeFrameCache; oaktask precache/export and
oakrender_video_ticket_params take the value handle
- color: OCIOBaseNode/OCIOLutNode hold OakColorProcessor handles
(dtors added); oakrender gains color_processor_create_transform/
create_lut/create_grading_primary/get_native and LUT library
queries, keeping all OCIO transform construction inside oakrender;
oaknode gains colormanager_wrap_borrowed/get_native
- RenderManager::instance() check -> oakrender_manager_available();
cancel_video_tasks and disk cache path go through manager C API
- remaining node->render C++ symbol: only olive::Texture::~Texture
via Variant's shared_ptr payload (recorded exception, same class as
the UndoCommand inheritance)
Tests: new cache/color/manager/colormanager cases; all standalone
trees green (common 196, codec 22, audio 40, task 112, render 63,
timeline 125, node 98, plugin 102).
- ViewerOutput owns timeline markers/work area via refcounted
OakTimeline* value handles (oaktimeline_*_create) instead of C++
objects
- oaktimeline C API: add marker_list_create/marker_add/
workarea_create/workarea_set_enabled; handle boxes gain an optional
deleter for owning handles
- oaknode_node_get_markers/get_work_area return addref'd OakTimeline*
handles via out params (named-struct forward declarations avoid the
public header cycle); drop OakNodeMarkerList/OakNodeWorkArea
- serializers 210528-230220 load/save markers and work areas through
the oaktimeline C API; SerializedMarker POD replaces
std::vector<TimelineMarker*> in the serializer interface
- Sequence::add_default_nodes uses oaktimeline_add_track_command
- clip.cpp display-mode enums come from the new neutral
include/timeline/displaymode.h; delete src/node/transition/timeline
- oakcommon xml: add oakcommon_xml_reader/writer_wrap_native borrowed
wrappers (C++ adapter use)
- liboaknode now has zero C++ symbol references into liboaktimeline
Tests: new owning-handle and wrap_native cases; all standalone trees
green (common 196, codec 22, audio 40, task 110, render 49,
timeline 123, node 96, plugin 100).
- de-Qt src/plugin/src (olivehost/oliveplugininstance/oliveclip/
paraminstance/image/pluginprogressreporter); QMessageBox/
QApplication replaced by facade callbacks
- new C ABI in include/plugin/{error,host,instance}.h with
refcounted OakPluginInstance value handle
- paraminstance bridges via oaknode C ABI (OakNodeNode value handle,
oaknode_node_identity registry); undo via oakundo C ABI
- oliveclip textures are OakRenderTexture value handles; oakrender
gains texture/copier/ticket C API additions
- oaknode gains get_input_at_time/set_input_at_time_undoable/
node_identity/sequence_from_node/sequence_set_default_parameters/
find_input_footage
- move avframeptr.h to src/common/src (shared by codec and render)
- node transition pluginSupport stubs bridge the real oakplugin
headers; all oaknode-building standalone trees add src/plugin and
link oakplugin into their test binaries
- plugin tests self-sufficient (ipc shim, OfxHost force_load,
PRE_TEST discovery, OCIO env); timeline standalone gains
render/c_api
- restore ffmpegdecoder.cpp in src/codec/src/ffmpeg/CMakeLists.txt
(dropped in 3d004c081, caused jump-to-0 in decoder/encoder tests)
All six standalone trees green: codec 22, audio 40, task 110,
render 49, timeline 121, plugin 100.
- de-Qt all 11 sources: markers/workarea lose QObject/signals (list
re-sort via direct resort() call, drawing moves to the app layer),
explicit unique_ptr ownership for marker lists and viewer's
workarea/markers
- timeline undo command families (split/pointer/ripple/general/track)
now hold oaknode C handles and do all graph work through the oaknode
C ABI (no adapter layer); gaps are attached to the project graph
before insertion, orphan handles tracked and freed
- fix the de-Qt severed Block->Track length-changed chain with a
direct block_length_changed() call (positions were stale after
split/trim)
- expand oaknode C API by ~20 functions needed by timeline
(copy_in_graph, block kind/casts, connect_element, input arrays,
tracklist family, marker/workarea borrowed outlets)
- pure C ABI in include/timeline (marker/workarea/edit, command
factories returning OakUndoCommand), oakcommon XML get_native
accessors
- oaknode<->oaktimeline resolve each other at runtime; standalone
drivers link both into test binaries
- tests: oaktimeline 117, regressions oakcommon 193 / oaknode 96 /
oakrender 42 / oakcodec 18 / oakaudio 36 all green
- copy engine/render to src/render/src (sunk param types excluded),
de-Qt in five parallel groups: core machinery (tickets/worker pool/
jobs), caches, color/texture, preview/IPC, GPU backends
- replace Qt GL/Vulkan wrappers with native context abstractions
(CGL/EGL/WGL, raw vulkan.h), QProcess with POSIX WorkerProcess,
QJsonObject with a minimal NDJSON-compatible workerjson (wire
protocol unchanged), QDataStream disk state with a byte-compatible
BinaryStream
- signals become single std::function callbacks or facade-triggered
calls per the documented signal/slot strategy
- pure C ABI in include/render + src/render/c_api (renderer/cache/
color/manager families, OAKRENDER_E_* codes), 37 gtest cases
- bridge src/node/transition/render/* stubs to the real oakrender
headers, closing the node<->render cycle: liboaknode links
liboakrender, zero dangling symbols
- docs: M7 implementation status + oakrender semantic-change notes
- strip QAbstractItemModel/QAction/signals-slots from UndoStack (UI
concerns belong to the app layer), index_changed becomes a
std::function callback
- decouple UndoCommand from Project via an optional modified-flag
callback pair
- add pure C ABI in include/undo + src/undo/c_api (oakundo_ prefix,
vtable-based command wrapper, OAKUNDO_E_* error codes)
- fix three engine-side defects: jump(0) infinite loop,
MultiUndoCommand child leak, push_pre_executed not undoable
- add gtest suites (22 cases) and a standalone build driver
- de-Qt all classes under src/common (std::string/vector/mutex,
std::filesystem, expat-based XmlStreamReader/Writer)
- add pure C ABI in include/common + src/common/c_api: opaque handles,
init returns NULL on failure, free(NULL) is a no-op, out-params with
negative OAKCOMMON_E_* error codes (include/common/error.h)
- remove single-consumer classes from oakcommon (html, jobtime,
otioutils, playbackaudioclock, tohex, util, avframeptr,
crashpadinterface/crashpadutils, autoscroll, digit, range); their
destinations are recorded in docs/zh/plans/riir/notes.md
- add gtest suites under src/common/tests (127 cases), standalone
build driver in src/common/standalone
- riir.md: split project file read/write into standalone oakstorage
module (pluggable backend, DB-replaceable); add Mermaid data flow
diagram of all modules; adjust batch table and milestones
- riir/04-interfaces.md: new provides/consumes contract matrix for
all modules
- riir/M10-oakstorage.md: new manual with frozen C API (typed opaque
handles, manual vtable for storage backends, URI addressing)
- riir/01: codify pure-C OO interface rules (typed handles instead of
void*, init/free pairs, manual vtables, no C++ objects or member
calls across shared library boundaries); upper layers issue commands
only, no module-to-module event subscriptions (async task callbacks
excepted)
- sync 00/02/03 and M2-M9 manuals: remove subscribe APIs, replace
void* with typed handles, update tests accordingly
New app/playback/playbackcontroller.{h,cpp}: a lazily created
process-wide singleton whose set_playhead() forwards to
oakengine_viewer_set_playhead and re-broadcasts playhead_changed as a
plain Qt signal. Every app-side oakengine_viewer_set_playhead call site
(17 across viewer, timelinewidget, timelineview, import tool,
timebasedwidget, keyframecontrol, export dialog, mainwindow) now goes
through it.
Migrate the first four playhead subscribers off the raw C event
subscription / EngineEventBridge to the controller signal:
- TimeBasedView (issue 1)
- NodeParamViewWidgetBridge (issue 2)
- NodeParamViewKeyframeControl (issue 3)
- NodeParamViewConnectedLabel (issue 4)
Each stores a QMetaObject::Connection filtered on its viewer node and
disconnects on teardown; the viewer_sub_ members are gone. Plan docs
mark issues 0c and 1-4 as done.
Closes#30, closes#31, closes#32, closes#51, closes#52.
Compiler hygiene (all platforms):
- Silence warnings across the tree: missing override, -Wreorder ctor
init, -Wshadow, -Wsign-compare, missing switch cases, unused
functions/captures, Qt 6.11 deprecations (QMouseEvent/QDropEvent
accessors, qAsConst, Q_FOREACH over non-shared containers,
AA_UseHighDpiPixmaps) and the .bak/ backup tree removal.
- Fix regressions from the cleanup: missing clip decls in
capi/timeline.cpp, plugin.cpp rename fallout, panel setFocus
ambiguity, QGraphicsItem::pos vs event->position(), duplicate
k_push_button case, boolean test variable.
Windows:
- Qt portability: CommandLineParser is_set/add_option, QTimeZone
systemTimeZone (QTimeZone::LocalTime is 6.11-only), k_progress_* enum.
- Linking: stop adding oakengine to OLIVE_LIBRARIES (import lib plus
oakengine-obj caused multiple definitions); add OAKENGINE_STATIC so
internal consumers no longer reference __imp_* stubs.
- oakengine.ver: export olive::Renderer typeinfo so liboakgl.so can be
dlopened (Linux), DynamicRenderer no longer dlcloses backend libraries
(crash in RenderManager's dtor calling into unmapped memory).
- OTIO runtime: copy DLLs next to every binary on Windows instead of
relying on PATH (0xc0000135 in gtest discovery).
- Headless GL: the runner only has GDI OpenGL 1.1, killing every render
worker. Deploy Mesa llvmpipe as opengl32sw.dll (Qt's software-GL
channel) with QT_OPENGL=software, and let QT_OPENGL override the
AA_UseDesktopOpenGL default. ExportTask fails fast after 8 consecutive
undelivered frames instead of segfaulting or grinding forever;
FFmpegEncoder::write_frame tolerates null frames.
- Tests: GetTempPathA+PID temp dirs, GetLongPathNameA for 8.3 names,
forward-slash normalization when comparing project filenames.
Linux:
- Install libshaderc-dev so oakvulkan compiles GLSL (Vulkan tests).
- Accept UNORM floor-or-round (63/64) in the blit ping-pong test.
- Skip MainWindow construction test on the offscreen QPA (cannot paint
QOpenGLWidget).
Also: oak_cli_transcode gets a 300s ctest timeout, worker logs GL
context version and LoadGraph/render_frame stages, and
docs/plans/eliminate-event-bridge-issues.md (English translation).
- capi: oakengine_node_output_connection_at/_at_ex returned the source
node as the connection destination; the actual destination is
conn.second.node(). Out-edge enumeration was useless, so the node
view could only draw in-edges and randomly lost whichever edges
needed the out-edge path (random per context build order).
Regression test in oakengine_node_test
- project teardown: Project::clear() pre-notifies node removal while
nodes are fully constructed (observers used to crash on
half-destroyed nodes); childEvent suppresses the removal dance while
clearing; Node::disconnect_all/disconnect_edge get a silent mode for
teardown so no invalidation/events touch dying members
(is_being_cleared); ClipBlock marker disconnect guarded against
dead viewer/markers; ProjectCopier and PreviewAutoCacher drop
project references on Project::destroyed instead of disconnecting
dead objects at shutdown
- preview: add oakengine_preview_request_get_audio_sample_count; the
viewer queried sample count by passing nullptr to get_audio_samples
which rejects it, so all playback audio was silently dropped
- app: fix unterminated input-id memcpy in ResolveGroupInput
(nodeparamviewitem, widgetbridge) that corrupted every parameter id
- app: unsubscribe raw C-API event subscriptions in destructors of
NodeParamViewKeyframeControl, NodeParamViewConnectedLabel and
ExportDialog; playhead events used to fire into dead widgets
(crash when dragging the playhead)
- tests: preview request roundtrip (video frame + audio range) and
free-while-active teardown coverage; env-gated OAK_DEBUG_EDGES /
OAK_DEBUG_INVALID_INPUT diagnostics
- docs: investigation notes in docs/zh/
- app/ no longer includes engine C++ headers nor holds engine C++ types:
engine access goes through the oakengine C ABI plus C++ wrappers
(oakutil/oaknode.h, oakutil/oakvideo.h) and app-local mirror types
(tooltypes, trackreferencehandle, timelinecommonapp, keyframetypes,
subtitleapp, serializedlayoutinfoapp, nodevaluehandle, sliderdisplaytypeapp)
- engine: new C ABI functions for block/track/clip/transition navigation
and predicates, links, caches, waveform/playback, disk folder,
sequence_track_list, node_free, footage_is_valid, block_get_track,
get_brush; loadotio/saveotio ported to the current engine API
- OTIO is now a required dependency: CI and CD build it on every
platform, FindOpenTimelineIO fixed for OTIO 0.16/0.19 (the old deps
include requirement silently disabled OTIO everywhere), runtime
libraries are bundled into packages and copied next to macOS binaries
(oak_copy_otio_runtime)
- fix ProjectViewModel drag&drop mime read/write size mismatch (segfault)
- unify color label naming (k_olive -> "Oak") in the app-side mirror
- docs: OTIO required, FFmpeg minimum corrected to 6.0 (en/zh)
- gtest suite: 1925 passed, 0 failed
Move the pure-header utilities shared by app/ and engine/ out of
engine/common/ into a new shared/include/oakutil/ layer (define, lerp,
decibel, digit, range, crashpadutils, autoscroll, qtutils, filefunctions
declarations, and a trimmed xmlutils exposing a CancelAtom-free void*
overload). engine/common/ keeps forwarding headers so internal include
paths are unchanged; app/ now includes oakutil/* directly.
engine/node/project.h gains an explicit NodeGroup forward declaration
previously obtained transitively through the old xmlutils.h.
Move the finished migration campaign docs (handoffs v3-v6, roadmap,
R5 guides, R6 cleanup, R7 pure-ABI) from docs/zh/ into
docs/zh/plans/completed/ with an archive README; fix all
cross-references; refresh plans/README.md index (active plans now
marked unlocked).
R7-A (Qwen 3.8 Max): oakengine/display.h rewritten to the POD contract
from r7-pure-abi-plan.md - oak_video_params everywhere, opaque
texture/frame handles with retain/free protocol (engine-heap control
blocks), OakSharedBuffer refcounted wrapper for the QVariant playback
path. All TexturePtr/FramePtr gone from app (47 sites).
R7-B (Qwen 3.8 Max): liboakengine.so exports 3486 -> 19 C++ symbols
(version script oakengine.ver: oakengine_* plus the documented
oakgl/oakvulkan dlopen plugin ABI). oakengine-obj OBJECT library feeds
both the shared lib and the test binaries (-rdynamic so dlopen'd
backends resolve engine objects).
Fix (Kimi K3): producer/consumer type mismatch - viewerdisplay
unpacks OakSharedBufferPtr but viewer.cpp pushed raw void* handles,
so no frame ever reached the display widget (all 5 vulkan viewer
tests timed out with 'never received a texture'). Producers now wrap
with oak_make_shared_frame / oak_make_shared_texture(retain).
Verified: build 0 errors, ctest 45/45, nm U _ZN5olive = 0 in
oak-editor/oak-render-worker/oak-cli, 19 exported C++ symbols in
liboakengine.so (all documented plugin ABI).
Complete documentation set for the facade migration (B1-R6) and beyond:
facade-migration-roadmap, handoffs v3-v6, R5 guides, R6 cleanup plan,
R7 pure-ABI plan, long-term plans (riir/ai-agent/gtest/ui-redesign),
updated Chinese README draft, UI design mockups, and the Google Test +
struct-typedef rules in CONTRIBUTING.
