- Fix SIGSEGV in PluginMisc.Keyer by linking Param::SetInstance to instances.
Olive's custom param instances (IntegerInstance, DoubleInstance, etc.) were
not passing the SetInstance pointer to the OpenFX HostSupport base class,
leaving _paramSetInstance as nullptr. When Keyer called paramSetValue during
createInstanceAction, the suite function dereferenced the null pointer in
paramChangedByPlugin(). Now newParam() passes 'this' to every constructor.
- Fix render-thread crash when OFX plugins set params during rendering.
MinOFX calls paramSetValue inside createInstanceAction from the render
thread. SubmitUndoCommand() used to push undo commands directly to
UndoStack, which modifies QAction state (GUI-only). Added IsGuiThread()
check: non-GUI threads execute redo_now() and discard the command without
touching the undo stack.
- Enable PluginMisc.MergeOver and PluginMisc.Keyer integration tests.
MergeOver now supplies both Source and Bg textures; Keyer uses U16 format.
Both pass in the full test suite.
- Make ViewerQueue thread-safe with QMutex around AppendTimewise/PurgeBefore.
Adds copy ctor and assignment to support mutex-per-instance semantics.
Hide non-texture OFX params from node graph
--------------------------------------------
OFX plugins like ColorCorrect expose dozens of scalar parameters as
node inputs, making nodes extremely tall and pushing Source/Mask far
down. Previously attempted via kInputFlagHidden, but that also hid
them from the parameter panel.
Fix: move the filter to NodeViewItem::IsInputValid() instead.
For OFX plugin nodes (getPluginInstance() != nullptr), only
kTexture inputs are rendered as ports. Scalar parameters remain
fully visible in the parameter panel.

Standardize OFX host coordinate system
--------------------------------------
Olive's OFX host had partial and inconsistent coordinate handling.
1. Fix Project coordinate methods
- getProjectSize() / getProjectExtent() / getProjectOffset()
now multiply X by pixel_aspect_ratio(), returning canonical
coordinates per the OFX spec.
2. Fix Clip default RoD
- OliveClipInstance::getRegionOfDefinition() default now returns
{0, 0, width*PAR, height} instead of raw pixel coords.
3. Add parameter coordinate system conversion
- DoubleInstance / Double2DInstance / Double3DInstance now check
_descriptor.getDefaultCoordinateSystem().
- For kOfxParamCoordinatesNormalised:
get: internal pixel value -> normalised (divide by extent)
set: normalised plugin value -> pixel (multiply by extent)
- DefaultValueForParam() also converts normalised defaults to
canonical before storing in Node, keeping Olive internal/UI
values consistently in pixel space.

ColorCorrectOFX and similar plugins declare per-channel controls
(Gamma, Contrast, Saturation, Gain, Offset) as kOfxParamTypeRGBA.
Olive previously mapped every RGBA param to NodeValue::kColor and
rendered it as a ColorButton, which is semantically wrong for
adjustment sliders.
This commit adds heuristic semantic detection to distinguish
"true color" inputs (color pickers) from "per-channel scalar"
inputs (float sliders):
- label/hint/name keywords ("gamma", "contrast", "gain", ...)
- display range outside [0, 1]
- uniform default values across all channels
The detected semantic ("color" or "scalar") is stored as the
node input property "color_semantic". The display range and hint
are also persisted as "min" / "max" / "tooltip".
NodeParamViewWidgetBridge now branches on "color_semantic":
- "scalar" → 4× FloatSlider (reuses existing ProcessSlider /
keyframe-track logic, since kColor already splits into 4 tracks)
- otherwise → ColorButton (unchanged)
All 4 test suites pass.
Refactor FFmpeg frame processing and improve focus management in panels. Add memory sanitization for debug builds and update KDDockWidgets integration.
God damn this was a big oof. Pasting was inadvertently making duplicates of the footage node(s) every single time. Worst case was if the clip was connected to a nested sequence. Every time someone copy/pasted in my large-scale project, it would add another 1000 nodes to the project. It's about fucking time this was fixed.
