Mike-Solar 7832cb30b3 build: move render worker out of app/ into top-level worker/
- oak-render-worker now builds from worker/ (own CMakeLists.txt) as a
  peer of app/; RenderWorkerPool resolves the new build-tree location
- deduplicated the Linux install() rules for the worker
- worker-spawning tests resolve build/worker instead of build/app
- cd.yml: Windows staging copies the worker from its new output path

Mike-Solar 76f5c2a65b color: input colorspace auto-detection, HDR export tags, LGG/white balance nodes, more LUT formats, waveform parade
- media color primaries/transfer tags now flow from the FFmpeg probe
  through VideoParams into Footage::get_colorspace_to_use(); precedence
  is user override > media tags > project default
- export nclc tags derive from the output colorspace (PQ/HLG/BT.2020,
  P3, sRGB, Rec.601, Rec.709) instead of hardcoded BT.709
- new OCIO Color Grading (Log) node (lift/gamma/gain) and White Balance
  node (kelvin temperature + tint, HDR-safe)
- LUT whitelist extended to 9 OCIO-supported formats
- waveform scope gains an RGB parade mode (GPU and software paths)
- tests updated for the new colorspace precedence

Mike-Solar a7ddc0f114 audio: master-clock playback timing, output clock compensation, buffer config, interpolated speed
- 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

Mike-Solar 0c02ff0d77 proxy: isolate proxies from export renders and improve proxy workflow
- FootageJob::should_use_proxy() centralizes the proxy decision; worker
  pre-decode now honors the render mode so exports always decode the
  original media (previously every frame was pre-decoded from proxies)
- global Tools > Use Proxy Media toggle with footage invalidation
- ffmpeg -progress parsing for real percentage feedback while generating
- divider mode (1/2, 1/4, 1/8 of source resolution) with UI, proxy
  filename tags and per-footage persistence (pdivider)
- Media Offline warning slat rendered for missing footage
- regression tests: export isolation, relink invalidation, offline slat,
  progress parsing, divider arguments

Mike-Solar bb40b4923e style: unify identifier naming per updated conventions
Automated with clang-tidy readability-identifier-naming (config added to
.clang-tidy) plus scripted passes, per the updated rules now documented
in CONTRIBUTING.md:

- types (class/struct/enum/alias/template params): PascalCase
- functions, variables, members: snake_case (incl. rational -> Rational)
- private/protected members: trailing underscore; static member
  variables likewise (instance_, available_themes_)
- constants and enum values: snake_case (kLinear -> k_linear,
  F32P -> f32p); ALL_CAPS reserved for macros
- macros: OAK_ prefix (OLIVE_ADD_TEST/OLIVE_ASSERT/OLIVE_CONFIG ->
  OAK_ADD_TEST/OAK_ASSERT/OAK_CONFIG, GL_PREAMBLE -> OAK_GL_PREAMBLE,
  include guards -> OAK_*)
- file names: all lowercase (Current/Plugin/OliveHost/OliveClip/
  OlivePluginInstance -> current/plugin/olivehost/oliveclip/
  oliveplugininstance)
- getters share the member name sans underscore, setters set_foo()
- Qt and third-party (OpenFX) virtual overrides and framework callbacks
  keep their original names (exempt in .clang-tidy)

Manual follow-ups required where automation could not reach:
- string-based QMetaObject/SIGNAL/SLOT references updated to renamed
  methods (AddTask, CreatedFile, DeleteSpecificFile, moveSelectionUp, ...)
- macro bodies referencing renamed methods (OLIVE_CONFIG,
  NODE_DEFAULT_DESTRUCTOR, MANAGEDDISPLAYWIDGET_*)
- self-shadowing locals renamed where signals/methods became same-named
  (size_changed, worker_count, selected_items, import param, filters)
- third_party OFX member/namespace usages restored (OFX::Host::*,
  _created, _clipPrefsDirty, createInstance, clearPersistentMessage)
- STL protocol aliases restored (const_iterator) with .clang-tidy
  ignore rules; qHash overloads restored

Full build and test suite pass: ctest 4/4, ~1960 gtest cases green.

Mike-Solar b0aa683499 fix: dangling OpenGL context crash and uninitialized audio frame size
- OpenGLRenderer: hold the viewer-owned QOpenGLContext in a QPointer so
  DestroyInternal() safely skips it when the context has already been
  destroyed by Qt's shared-context lifecycle. Fixes a SIGSEGV when the
  full gtest suite ran MainWindow.ConstructsOffscreenWithPanelsAndMenus
  after earlier viewer tests.
- PreviewAudioDevice: add SetParams() deriving bytes_per_frame from the
  audio format (bytes per sample * channel count) instead of staying 0.
2026-07-19 13:58:06 +08:00
Mike-Solar 004e942cf9 fix: remaining issues recorded during test coverage work
- RenderManager: GPU-side members (context_, decoder_cache_,
  shader_cache_, auto_cacher_, worker_pool_, decoder_clear_timer_) were
  left uninitialized when the configured graphics backend is unknown
  (e.g. dummy); ViewerWidget then dereferenced garbage and crashed.
  Initialize them at declaration
- CurveView::SelectKeyframesOfInput ignored its reference parameter and
  selected keyframes of every connected track; select only the
  requested track's keyframes
- SeekableWidget::SeekToScenePoint dereferenced GetViewerNode()
  unconditionally; skip the playhead update when no viewer is connected
- LoadOTIOTask: unknown root schema leaked the freshly allocated
  project_ (delete + reset; OTIO is not enabled in local builds so this
  file is compile-verified by inspection only)

Locked by new tests: RenderManagerDummyBackend,
TimeRuler.SeekToScenePointWithoutViewerIsNoOp,
CurveViewTest.SelectKeyframesOfInputSelectsOnlyRequestedTrack

Mike-Solar 2aa921b215 fix: bug-fix sweep across node, audio, render, plugin subsystems
Node core:
- MathNode/TrigonometryNode combo strings realigned with Operation enums
- mathbase scalar/vector operand pick no longer uses bitwise type checks
- NodeSetPositionAndDependenciesRecursively moves dependencies again
- RemoveAllKeyframes undo actually restores keyframes
- NodeGroup GetInputName null-deref guard, passthrough ids use input id
- NodeValueTable::Has is an exact type match; tag fallback only for
  empty tags; kStrCombo/kPushButton get data type names
- delete_all_keyframes no longer loops forever on unparented keyframes;
  keyframe-load failures propagate; rational interpolation falls back to
  double; OpacityEffect no longer leaks its internal MathNode

Audio/footage:
- AudioVisualWaveform: GetSummaryFromTime underflow OOB read, TrimIn
  prepend length bookkeeping, OverwriteSums source channel indexing
- PanNode inserts the pan value into the sample job (keyframed pan
  works); OutputParamsChanged is emitted on device change; PortAudio
  device indices are validated before Pa_GetDeviceInfo
- Footage: AdjustTimeByLoopMode no longer hangs/UBs on degenerate
  lengths, GetStreamIndex bounds-checked, CheckFootage clears stale
  state on missing files, failed probes are not cached,
  FootageDescription::Load requires its own root element

Render/track:
- ViewerOutput pushes the tagged samples value; TrackList disconnects
  the track-height lambda; GetTrackFromReference validity check
- RenderManager dummy backend: null-initialized threads, guarded
  decoder-cache/timer paths; Renderer::Destroy releases color cache
  shaders/textures; unknown dynamic backends no longer alias to oakgl
- SharedMemoryRegion POSIX attach validates segment size; ReadMessage
  skips blank lines instead of failing; GC counter clamped;
  IsRenderingCustomRange implemented; TimeOffsetNode gets a true
  inverse OutputTimeAdjustment; zero-speed clips return the held frame

Plugin/nodes:
- OliveClip: stored default region of definition is honored, on-demand
  images are cached; OliveHost sets host identity properties and logs
  instead of showing modal dialogs offscreen; Plugin.h dead decls gone
- DespillNode guards graph-less use with Rec.709 fallback; description
  typos fixed (despill, swirl); mosaic applies when only one axis
  matches; Windows-only Project filename separator test fixed
2026-07-17 08:26:48 +08:00
Mike-Solar d9a4e27045 tests: coverage round 8 (serialization, folder, text/polygon, probe, render tail)
- node_save_load_test: Node Save/Load round trips for values, keyframes,
  hints, caches, connections, positions
- node_polygon_folder_test: Folder child management, PolygonGenerator
  rasterization/gizmos, TextGeneratorV1/V2
- footage_probe_test: real FFmpeg/OIIO probing of demo.mp4/img.png,
  metadata cache, footage state transitions
- render_tail_test: DynamicRenderer, color-context shader plumbing,
  PreviewAutoCacher pause/clear paths, DiskManager edges,
  AudioPlaybackCache segment I/O

Also fixes AudioPlaybackCache::WritePartOfSampleBuffer, found by the new
tests: zero padding was written via QFile::write(const char*) which
treats the buffer as a NUL-terminated string, so no padding bytes were
ever written; the write length was also computed from the segment end
instead of the range end, making WriteSilence() spin forever on an
empty buffer
2026-07-17 07:48:18 +08:00
Mike-Solar 547c2480e0 color: global LUT library, LUT error reporting, clamp + display fixes
- Add a global LUT library: user-configurable directories (new
  Preferences > LUT tab) scanned recursively for .cube/.3dl files; LUT
  node file pickers offer the library dirs as sidebar shortcuts via a
  'lut_library' input property handled by the param view bridge
- OCIOLutNode no longer fails silently: missing files, unsupported
  extensions and OCIO load errors are recorded in last_error() and
  surfaced in the status bar (input still passes through for rendering
  safety)
- ColorDialog: re-enable the display -> reference conversion using
  ColorProcessor::kInverse with a validity guard, and re-enable the
  Display tab in ColorValuesWidget; covered by a round-trip regression
  test proving the old OCIO inverse crash no longer occurs
- OCIOGradingTransformLinearNode: enforce the OCIO clampWhite >
  clampBlack invariant per frame in Value() so keyframed/connected
  values cannot produce invalid grading transforms, and constrain the
  white clamp UI minimum whenever the black clamp is static
- Regression tests for LUT extension checks, direction switching, node
  error reporting, LUT library scanning, display inverse round-trip and
  clamp enforcement
2026-07-16 22:53:33 +08:00
Mike-Solar 6aaf37e2e5 proxy: per-footage presets, audio in proxies, configurable ffmpeg path
- Footage can store custom proxy parameters (width/height/crf/preset/
  extension/audio) that override the global settings; they are
  serialized with the project and used by every generation entry point
  via Footage::GetEffectiveProxyParams()
- Proxies now include the source audio streams (AAC) unless disabled;
  the proxy filename records the audio flag and offline audio rendering
  decodes from the proxy when present
- ProxyTask resolves ffmpeg from the new FFmpegPath config key first,
  then PATH, then common install locations (e.g. Homebrew on macOS),
  instead of relying on PATH only; the error message points at the
  preferences when no executable is found
- ProxyTask::BuildArguments() is extracted for testability
- Add ProxyIncludeAudio and FFmpegPath config defaults
- Add regression tests for the filename audio marker, config-backed
  params, ffmpeg resolution, argument building, and custom-param
  persistence
2026-07-16 22:31:37 +08:00
Mike-Solar 3a3ead6fc0 app: route all FFmpeg access through the ffmpeg_bridge C API
Replace every direct FFmpeg call in the editor and the render worker
with the pure C ffmpeg_bridge API, wrapped in thin C++ adapters that
preserve the original interfaces:

- avframeptr.h: olive::AVFrame adapter around FBFrame handles
- ffmpegutils: format conversion helpers on FB_* constants; the int
  overload is renamed GetCompatibleBridgePixelFormat to avoid a silent
  overload-resolution trap with the PixelFormat enum
- ffmpegdecoder/ffmpegencoder: rewritten as handle-based adapters over
  FBDecoder/FBProbe/FBEncoder/FBScaler/FBResampler
- audioprocessor: FBAudioGraph push/pull adapter
- pluginrenderer/OliveClip: sws/pixdesc usage converted to FBScaler and
  fb_pix_fmt_* queries
- AudioParams/channel layouts are plain uint64_t masks everywhere

Build integration: the root project no longer links FFMPEG directly;
only ffmpeg_bridge does. Binaries resolve the bridge library at runtime
via @loader_path inside the macOS app bundle (copied there post-build)
and via $ORIGIN/../ffmpeg_bridge/bin on Linux; on Windows the DLL is
installed next to the executables, so packages on all three platforms
ship the bridge library.

ffmpeg_bridge gains the extra API the adapters need:
fb_frame_make_writable, fb_decoder_get_format_duration,
fb_resampler_convert_frame, FB_PIX_FMT_YUV440P, SRT validation in
fb_probe_read_subtitle_stream, packed/planar fixes in
fb_encoder_write_audio, and a component-size fix in
fb_pix_fmt_component_size.

Mike-Solar 3be4294e15 Fix Linux audio backend preference and worker footage render crash
- On Linux, automatically prefer PipeWire/JACK/PulseAudio over ALSA
  even when a saved ALSA device name exists in config.
- Restore Footage length after deserialization so worker snapshots
  have valid stream lengths and video playback can advance.
- Guard ResolveDecoderFromInput and ProcessAudioFootage against a
  null decoder cache to prevent worker crashes on direct Footage ->
  ViewerOutput connections.
- Keep Linux signal backtrace handler in the render worker.
- Add Oak project SVG logos.
2026-07-14 22:33:30 +08:00
Mike-Solar b4b52abbd4 Remove noisy graph-snapshot logs and add waveform-sync diagnostics
- Strip the dense RenderWorkerPool debug messages about cached/stale graph
  snapshots and cleanup to reduce log spam.
- Add qDebug logging and status-bar feedback to
  TimelineWidget::SynchronizeSelectedClipsByWaveform() so we can see why the
  sync action does nothing (e.g. not enough cached clips or no usable offset).

Mike-Solar f0d41eae52 build: rebrand output artifacts to Oak and fix macOS QML deployment
- 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.

Mike-Solar ea78558a31 render: reference-count graph snapshots to prevent premature deletion
Proxy generation modifies the project, causing graph snapshots to be
rewritten. The old implementation deleted the previous snapshot
immediately, even though queued render jobs still held its path. The
worker then failed to load the deleted file.

Add per-path reference counting:
- Increment when a job is created with a snapshot path.
- Decrement when the job is processed, cancelled or removed.
- Only delete a snapshot when its reference count reaches zero and it
  is no longer the cached snapshot for the project.

Also keep snapshots in the system temp directory as before, since the
location itself was not the bug.
2026-07-13 13:43:20 +08:00
Mike-Solar 8580542ac7 render: write graph snapshots to AppLocalData instead of system temp
The worker process on macOS could not see the graph snapshot when it
was placed in /var/folders/.../T (likely sandbox/working-directory
visibility). Write snapshots to a 'render-graphs' subdirectory of the
application's persistent data location instead, which both the editor
and the worker can access on all platforms.
2026-07-13 13:29:55 +08:00
Mike-Solar 5a5ad3bc14 render: add diagnostics for worker graph load failures
- Report QFile::errorString() when ProjectSerializer::Load() fails to open
  the graph file, so the worker log shows why instead of an empty detail.
- In olive-render-worker LoadGraph(), check file existence, size and
  readability before delegating to the serializer and log the attempt.
2026-07-13 13:25:25 +08:00
Mike-Solar 182bfd0aad build: bundle render worker/backends and fix concurrent param test
- Make olive-editor depend on olive-render-worker on all platforms so the
  worker is always built with the main app.
- Copy olive-render-worker and dynamic render backends (oakgl, oakvulkan)
  into the macOS app bundle next to the executable.
- Include oakgl.dll and oakvulkan.dll in the Windows NSIS installer.
- Fix PluginSmokeThread.ConcurrentParamAccess CI failure by adding a mutex
  around IntegerInstance's no-node fallback storage and serializing the
  test's set/get pair.
- Hide the render worker's Dock icon on macOS via
  NSApplicationActivationPolicyProhibited.

Mike-Solar 5c8f80480d UI: flatten preferences behavior tabs and add node parameter editor shortcut
- Move Behavior-General options (hover focus, slider ladder, scroll zooms)
  into the General preferences tab.
- Move Behavior-Audio option (audio scrubbing) into the Audio preferences tab.
- Promote remaining Behavior categories (Timeline, Playback, Project, Nodes,
  Rendering) to top-level sidebar entries without the 'Behavior - ' prefix.
- Update Chinese translations for the new sidebar titles and fill unfinished
  Behavior tab strings.

NodeView:
- Remove double-click jump-to-parameter-editor behavior; keep expand/collapse.
- Add right-click context menu item 'Show in Parameter Editor'.
- Add Shift+P shortcut bound to the same action.

Render:
- Fix crash in PreviewAutoCacher::ClearSingleFrameRenders when proxy playback
  causes a render ticket to finish synchronously before the watcher pointer is
  returned. Defer the watcher Finished signal via queued connection so the
  caller can safely register the watcher before it is deleted.
2026-07-13 10:19:30 +08:00
Mike-Solar 1f446f55b4 Cache color processors in render worker and canonicalize OCIO roles
ColorProcessor creation was done for every exported frame and the input
reference space was passed as a role string (e.g. "scene_linear"). If
getProcessor() rejected the role name the worker would crash, the pool
would retry the frame, and export throughput would drop to near zero with
minimal CPU/GPU usage.

- Canonicalize role names to colorspace names in ColorProcessor so
  "scene_linear" resolves to the config's actual colorspace.
- Wrap processor creation in a try/catch and initialize cpu_processor_ to
  nullptr on failure instead of dereferencing a null processor.
- Cache created ColorProcessor objects in the worker keyed by transform
  so OCIO processor/shader setup is only paid once per export.
2026-07-13 10:19:30 +08:00
Mike-Solar d66779d281 Apply export color transform in render worker
The export color transform was passed to RenderTask as a ColorProcessor,
but the worker IPC render_frame message never carried it. The worker
always set the ticket's coloroutput to null, so frames were returned in
the project's reference space and encoded without the chosen output
transform (e.g. Rec.709 / sRGB), causing the exported video to look
wrongly tinted.

Serialize the ColorTransform through the render_frame control message
and reconstruct the ColorProcessor on the worker side before rendering.
Also expose ColorTransform as a Qt metatype so it can be stored in a
ticket QVariant.
2026-07-13 10:19:30 +08:00
Mike-Solar ea37dc5da6 Prevent main-process crash when render worker dies during IPC write
When a render-worker process crashed or exited while the worker-pool
thread was writing a control message (e.g. right after an audio-sync and
drag operation triggered a new render), the main process received SIGPIPE
and terminated at WriteControlMessage().

- Ignore SIGPIPE in main() so QProcess can report the broken pipe through
  its normal error path instead of killing the application.
- Harden WriteControlMessage() / TryWriteControlMessage() to check the
  process state and the number of bytes written before waiting.
2026-07-13 10:19:30 +08:00
Mike-Solar 51ea3ca24e Use 10-bit packed preview format and add OCIO LUT regression tests
Renderer / preview:
- Switch the preview/display readback format from F16 to packed
  10-bit RGBA (PixelFormat::U10) to halve GPU->CPU/IPC bandwidth
  while keeping 10-bit panel precision.
- Add U10 support to VideoParams, FFmpeg/OIIO/OCIO utility mappings,
  OpenGL (GL_RGB10_A2), Vulkan (VK_FORMAT_A2B10G10R10_UNORM_PACK32),
  and plugin bit-depth lookups.
- Update preview autocacher comment to reflect the new behavior.

OCIO LUT tests:
- Add four E2E-style ColorLutNode gtests that drive a SolidGenerator
  -> OCIOLutNode graph through NodeTraverser and compare resulting
  pixels on the CPU. They cover forward/inverse transforms and verify
  that switching LUT direction and LUT file updates both the processor
  and the output pixels.

Cleanup:
- Remove a leftover SolidGenerator::Value debug fprintf.
- Capture render worker stderr in RenderWorkerFootageTest for better
  diagnostics.

Mike-Solar e8443f8f8f Fix crash when toggling Use Proxy during playback and proxy generation output format 2026-07-13 10:19:30 +08:00
Mike-Solar 0969e2adc5 Add diagnostics for proxy toggle synchronization
Add temporary qDebug logging to Footage, ProjectCopier,
RenderWorkerPool, and TimelineWidget to trace why Use Proxy cannot be
 toggled and why proxy footage may still be used after disabling.
2026-07-13 10:19:30 +08:00
Mike-Solar 818b76b64e Sync Footage proxy state to render worker copy project
Proxy state (enabled/path/state/etc.) is stored as Footage member data,
not as a Node input, so ProjectCopier did not synchronize it to the
internal copy project used by worker processes. This caused toggling
Use Proxy in the UI to have no effect on rendered output.

Add a Footage::ProxySettingsChanged signal and have ProjectCopier sync
the proxy state to the copied Footage node, marking the copy project
modified so RenderWorkerPool writes a fresh graph snapshot.
2026-07-13 10:19:30 +08:00
Mike-Solar 94250a7690 Fix proxy decoding path and add proxy generation diagnostics
- RenderWorkerPool::DecodeInputFrame now uses the proxy filename/decoder/stream
  from FootageJob when a proxy is attached, so generated proxies are actually
  used during render.
- Add qDebug/qWarning logging to TimelineWidget::GenerateProxiesForSelectedClips
  and ProxyTask::Run to diagnose why Generate Proxy appears to do nothing.
2026-07-13 10:19:30 +08:00
Mike-Solar ca22028a52 Defer OCIO LUT processor generation in render worker and fix stale graph snapshots
- Override OCIOLutNode::Value() to ensure the processor is created/updated
  before the color transform job is emitted.
- In the worker process, mark the processor dirty on input/config changes
  instead of creating it synchronously during LoadGraph, which blocked the
  main process waiting for the graph load acknowledgement.
- Keep eager processor generation in the main GUI process so the viewer
  cache is invalidated immediately when the LUT file or direction changes.
- Mark the ProjectCopier's internal render-proxy project as modified when
  its update queue is processed, and reset the flag after RenderWorkerPool
  writes a new graph snapshot. This fixes the worker loading a stale graph
  snapshot after switching cube files or direction, which caused the old
  LUT effect to persist.

All existing tests pass.

Mike-Solar e908786d43 Improve Vulkan Blit: caching, interpolation, swizzle, enable flags
- Cache a VkFramebuffer per texture to avoid creating/destroying one for
  every Blit() call.
- Create and cache both linear and nearest samplers; honor
  Texture::Interpolation in descriptor writes.
- Add single-channel image-view component swizzle (R -> RGB, A = 1) to
  match OpenGL grayscale behavior.
- Set texture-enable uniforms (NAME_enabled) when shaders declare them.
- Guard Blit() with null destination and emit a clear warning instead of
  recording an invalid render pass.

ctest passes 4/4 in both dynamic-backend ON and OFF builds.
2026-07-13 10:19:30 +08:00
Mike-Solar f4906862a1 Make Vulkan shader/UBO/layout path real enough for end-to-end blits
- Add shared UBO layout across vertex + fragment stages so vertex
  uniforms like ove_mvpmat compile and bind correctly.
- Rewrite uniform extraction/injection to avoid corrupting the UBO
  block and to keep explicit sampler bindings stable.
- Make the UBO and sampler descriptor bindings visible to both vertex
  and fragment stages.
- Add layout locations for vertex varyings (ove_texcoord) and fragment
  inputs so SPIR-V generation succeeds.
- Extend TransitionImageLayout() to cover all layout pairs used by
  upload/download/clear/blit.
- Add subpass dependencies to the cached render pass and leave
  destinations in SHADER_READ_ONLY_OPTIMAL after Blit().
- Move descriptor allocation before command recording and abort cleanly
  if allocation fails; switch Blit() to the persistent linear sampler.
- Add a gtest that creates a Vulkan backend, uploads a red U8 RGBA
  texture, blits through the default pass-through shader, and verifies
  the downloaded pixel is red. This test passes on the current system.

ctest passes 4/4; DynamicRenderBackend.* passes 3/1 (Vulkan fallback
skipped because Vulkan is available).
2026-07-13 10:19:30 +08:00
Mike-Solar f1d19a03f8 Harden Vulkan init/device selection and resource teardown
- Remove unconditional VK_KHR_swapchain request; offscreen renderer needs
  no device extensions, fixing failures on headless/CI setups.
- Enumerate physical devices properly and pick the first one with a
  graphics queue family instead of blindly choosing device 0.
- Check vkEnumeratePhysicalDevices/vkBindImageMemory/vkBindBufferMemory
  results.
- Validate FindMemoryType() result before allocation and log clear errors.
- Add a persistent linear sampler created in PostInit and destroy it in
  DestroyInternal.
- Fix DestroyInternal() early-return leak: now tears down the instance
  even if device creation failed.

ctest passes 4/4.
2026-07-13 10:19:30 +08:00
Mike-Solar 8b8aa945f0 Sync RenderManager::backend_ after DynamicRenderer fallback
DynamicRenderer::Load() can internally fall back from Vulkan to
OpenGL when the Vulkan library is missing or is_available() fails.
Previously RenderManager::backend_ stayed at kVulkan, so callers
asking RenderManager::backend() got the wrong answer. After a
successful dynamic load, sync backend_ from
DynamicRenderer::backend_name() and log any fallback.

ctest still passes 4/4 in build-default-on.

Mike-Solar b4e39e5bcd Address ChatGPT Vulkan review items
- 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).

Mike-Solar 225f8505c2 feat(render): dynamic OpenGL/Vulkan backend split and backend-neutral viewer
- 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.
