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.
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.
- 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.
- 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.
