- 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.
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.
- 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.
This commit fixes crashes (SIGSEGV in CImg blur_bilateral) and black-frame
corruption artifacts during playback and scrubbing on macOS Apple Silicon.
Root cause analysis:
1. macOS uses Tile-Based Deferred Rendering (TBDR). glFlush() does not
guarantee tile memory writeback, causing glReadPixels to read incomplete
tiles (black/corrupted frames) and cache them to disk.
2. Olive uses multiple shared OpenGL contexts (RenderProcessor contexts vs.
thread-local PluginRenderer context). glFinish() only waits for the
current context, not the shared context that produced the texture. CPU
readback in PluginRenderer could read partially-rendered tiles.
3. OlivePluginInstance and OliveClipInstance are not thread-safe. Concurrent
RenderProcessors could corrupt internal QMap/images_ and params_ via
setInputTexture/renderAction races.
Fixes:
- OpenGLRenderer::Flush() on macOS now uses glFinish() unconditionally.
- OpenGLRenderer::DownloadFromTexture() and OpenGLRenderer::Blit() insert
glFinish() before readback/detach to ensure tile writeback completes.
- PluginRenderer::RenderPlugin() now acquires a per-instance mutex to
serialize concurrent OFX render calls.
- Before CPU readback in PluginRenderer, flush the renderer that originally
produced each input texture, ensuring cross-context synchronization.
- RenderProcessor::ProcessVideoFootage() flushes after BlitColorManaged.
- Add black-frame detection in ProcessVideoCacheJob() to auto-purge TBDR-
corrupted cache files.
- Add diagnostic qDebug() logging in viewer, decoder, renderer, and plugin
paths to aid future debugging.

Just can't win with this one. I started with glFinish because it's technically the correct option, however it caused issues on a GPU, so I switched it out for glFlush. Then I started noticing other frame sync oddities that would be fixed by using glFinish, so I switched back. Now, not only is it causing GPU issues on one system, it seems to be causing GPU issues on others too. So now glFlush seems like the lesser of the two evils, and I'm just going to have to find a way around the aforementioned frame sync issues.
This will break some systems, but is necessary for frames not to corrupt under some circumstances. It sucks but that's the tradeoff we have to make.
I think it's time to get off OpenGL. It's not worth it anymore.

It's been 84 years, but the polygon generator not only works, but now has bezier support. The UI could still use some work, but this was the hardest part. I guess complex masking should be possible now, if perhaps slightly cumbersome until the UI is smoothed out.
If you run into new OpenGL issues, this is likely the commit that caused it.
I've tested this on as many systems as I have access to (including AMD, Apple,
Intel, and NVIDIA GPUs with a mixture of Windows, Linux, and macOS) and it
appears to work fine, however we all know how unpredictable GPUs can be.
This should help increase GPU performance and compatibility.
