- 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.
- Linux CD builds no longer disable Vulkan: the AppImage, deb, rpm and
Arch packages now build and ship liboakvulkan (the AppImage deploys
it via linuxdeploy --library so libvulkan is bundled too, and the
verify step checks both backend libraries); deb/rpm dependencies gain
libvulkan1/vulkan-loader; the Arch PKGBUILD gains vulkan-headers
- macOS CD installs vulkan-loader and exports VULKAN_SDK so
find_package(Vulkan) locates the Homebrew loader (previously the
Vulkan backend silently never built there)
- ffmpeg_bridge now installs to the standard lib directory with
/../lib RPATH instead of the non-standard ffmpeg_bridge/bin
layout (verified: editor, worker, oakgl and oakvulkan all resolve it)
- build guides (EN/ZH) document the macOS Vulkan backend dependencies
and the VULKAN_SDK variable
- Rename macOS bundle output from Olive.app to Oak.app.
- Rename editor binary to oak-editor and render worker to oak-render-worker.
- Rename crash handler output to oak-crashhandler.
- Update worker lookup, NSIS installer, Linux desktop/AppRun, crashhandler
symbol paths, and documentation for the new binary names.
- Update CD workflow paths and add -qmldir flags to macdeployqt so QtQuick
/ QML plugins required by KDDockWidgets are bundled, fixing the launch
crash on macOS.
- Update user-facing GitHub URLs to OakVideoEditorCommunity/oak.
- English and Chinese build.md now list macOS as a fully supported
platform and point to the dedicated macOS build guide.
- Chinese build.md Fedora dependency list synced with English: use
ffmpeg-free-devel and add bzip2-devel.
- Update CI badge URL to OakVideoEditorCommunity in README.
- Remove outdated TODO files, vcpkg.json, patch file and stale log.
- Clean up obsolete docs and move ofx-pluginrenderer-functions-zh.md
into docs/zh/.
- Document that Vulkan now passes an end-to-end upload/blit/download test
on real hardware.
- List recently landed fixes: shared vertex/fragment UBO, descriptor set
layout, render pass dependencies, image layout transitions, framebuffer
and sampler caching, grayscale swizzle, texture-enable uniforms.
- Add remaining gaps: iterative/pin-pong multi-pass Blit, 1/3-channel
upload/download alignment, and full viewer/proxy/export smoke tests.
- dynamic plan: mark that RenderManager::backend() now syncs with
DynamicRenderer's actual loaded backend after internal fallback.
- manual test plan: add checks in 10.2/10.3 that RenderManager reports
the actual runtime backend (OpenGL after Vulkan fallback).
No code changes; ctest passes 4/4.
- Add PickRenderableFormat / IsColorAttachmentSupported so 3-channel
Vulkan formats fall back to 4-channel when unsupported.
- Make oakvulkan target and C ABI check conditional on Vulkan_FOUND;
skip liboakvulkan build/dependencies when Vulkan headers/libs are
absent.
- Update Preferences tooltip to reflect Vulkan is an experimental
prototype that may fall back to OpenGL.
- Revise dynamic backend plan doc: phase 3/4/5 described as prototype
frameworks with runtime validation pending, and list recent Vulkan
fixes (init idempotency, descriptor/sampler lifetime, dynamic
viewport/scissor, render pass clear, format probing).
Both OAK_ENABLE_DYNAMIC_RENDER_BACKEND=ON and OFF configurations
build and pass ctest (4/4).
- Extract libolive-rendercore static library to minimize backend link boundary.
- Add DynamicRenderer adapter with C ABI (oakgl/oakvulkan shared libs).
- Make OAK_ENABLE_DYNAMIC_RENDER_BACKEND default ON with OpenGL fallback.
- Implement VulkanRenderer prototype (textures, shaders, UBO blit, readback).
- Add backend-neutral viewer readback path (offscreen -> QImage -> QPainter).
- Refactor PluginRenderer to be renderer-agnostic; OFX plugins fall back to CPU
path on non-OpenGL backends while preserving OpenGL render path.
- Add Renderer::AttachOutputTexture/DetachOutputTexture and C ABI forwards.
- Update docs/zh/render-backend-dynamic-plan.md for Phase 3/4/5.
