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).
- Linux GCC rejects QMetaType instantiation over incomplete types
(static_assert(sizeof(T))); Q_DECLARE_OPAQUE_POINTER every opaque
OakEngine* handle in the public headers so QList<OakEngineTask*> etc
compile
- Windows: gtest discovery ran the fresh exe before the DLLs were next
to it; use DISCOVERY_MODE PRE_TEST on WIN32 and copy the DLLs for
ctest time
- Linux: Qt6 metatype static_assert requires complete types; declare
OakEngineBlock with Q_DECLARE_OPAQUE_POINTER in the public header
(outside extern "C")
- Windows: gtest discovery runs the freshly linked test exe at build
time and it cannot find the DLLs (0xc0000135); copy oakcore/oakengine/
ffmpeg_bridge DLLs next to the test binaries on WIN32
- macOS: Imath header mixing between otio-install's stale bundled Imath
and Homebrew's Imath broke ImathBox.h (V2h undeclared); bump the OTIO
cache to v2 and drop bundled Imath headers so the system one is the
only set in play
- 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 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).
Even statically linked runtime libraries must not leak symbols: the
linker version script now whitelists oakcore_* only. nm reports 188
oakcore_* exports and zero anything else.
liboakcore is now a shared library that exposes only a C ABI:
- every value class (Rational, TimeRange, Color, Bezier, AudioParams,
SampleBuffer) and the free-function groups (StringUtils, fraction
utils, Timecode) is wrapped in an opaque-handle C API under
core/include/olive/core/oakcore/ (init/copy/free + self-first
functions), implemented in core/src/capi/
- consumers keep the original C++ API unchanged through same-name
wrapper classes that hold the handle and forward across the C
boundary; original implementations moved to core/src/oliveimpl
(namespace olive::core::internal) and are hidden from export
- TimeRangeList/TimeRangeListFrameIterator are reimplemented inline
over the wrapper (iterators/containers don't cross C ABI)
- generic Value container stays internal (unused by consumers) and is
no longer part of the public umbrella header
- hidden visibility + OAKCORE_BUILD export macro; nm shows zero
olive::* symbols exported
- install into the platform's standard libdir (GNUInstallDirs);
Windows DLLs next to the executables, macOS into the app bundle
- TimelineWorkArea::in/out/length now return by value: the wrapped
TimeRange getters return values, and forwarding them through const
references dangled (found via RenderWorkerFootageTest crash)
- tests: 9 new pure C ABI test executables (oakcore_*_test) covering
every public C function; 4 stale legacy core tests removed (they
targeted a long-renamed API and were never built due to a malformed
option() that also kept OLIVECORE_BUILD_TESTS off)
- CI/CD: oakcore.dll staged for NSIS, liboakcore.so added to the
AppImage validation list, build-tree DLL copies on Windows
- playback timer uses the audio output device as its master clock: the
PortAudio callback counts consumed frames (including underrun
zero-fill) so video cannot drift away from what is heard; wall clock
remains as fallback when no clocked output is running
- output clock compensates for device output latency; new Preferences >
Audio buffer size setting (0 = auto)
- SampleBuffer::speed() now uses linear interpolation instead of
nearest-neighbor sampling
- regression tests: audio-clock driven timer (fwd/rev/speed), wall
clock fallback, interpolation correctness
Ubuntu (FFmpeg 7.0) build failure: the public FB_PIX_FMT_* values were
hardcoded to AVPixelFormat enum values, but those shift between FFmpeg
releases (new formats are inserted mid-enum: X2RGB10 in 7.0,
RGBF16/GRAYF16 later), so the static_asserts in internal.h failed and
RGBF16LE/GRAYF16LE did not exist at all.
The FB pixel format values are now fixed identifiers translated inside
the library by pixel format name (stable across releases):
- fb::PixFmtToAV/PixFmtFromAV resolve the static table by name;
formats a decoder produces that have no static identifier (hardware
downloads like nv12/p010le/p210le) receive process-local dynamic ids
>= 1000 so they keep round-tripping through the API (scaler etc.)
instead of collapsing to NONE and crashing sws.
- All crossing points translated: scaler, frame get/set format,
decoder/probe stream info, encoder config and write_video_frame,
fb_pix_fmt_* utilities, fb_find_best_pix_fmt_of_list (which also
reinterpret_cast the caller's list; now translated element-wise and
properly NONE-terminated).
- nv12 and p010le get static identifiers as the common hardware
download formats.
- Hardware frame detection no longer compares pixel formats (breaks
across format spaces); it uses the existing fb_frame_is_hw().
macOS test failures (FFmpegBridgeEncoder.WritePngVideoAndProbeBack,
WritePcmAudioAndProbeBack): config.filename held a dangling pointer to
a temporary QByteArray (UB; happened to work on Linux). Keep the
QByteArray alive for the encoder's lifetime.
Windows (MSYS2 UCRT64) build failure: timecodefunctions.h used int64_t
without including <cstdint> (previously pulled in transitively).
Full gtest suite: 584 passed.
- rational: store num/den natively instead of AVRational; math operators
re-implemented natively (ported av_reduce/av_d2q/av_cmp_q semantics,
verified bit-exact against FFmpeg)
- AudioParams: replace AVChannelLayout member with a plain uint64_t mask
(new render/channellayout.h constants mirror AV_CH_LAYOUT_* values)
- Timecode: native rescale (av_rescale_q/av_rescale_q_rnd equivalents)
with 128-bit intermediate precision
- core no longer finds or links FFMPEG::avutil
Part of the FFmpeg isolation effort: all FFmpeg access is being moved
behind a dedicated shared library (ffmpeg_bridge).
