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).
