- open_hw_accel marks the device unavailable when the decoder OPEN fails (cuvidCreateDecoder OOM at 4K) too, not just device-context creation: without it every subsequent decoder session retried CUDA and flooded the log per open. - Decoder gains hardware_decoding(); the oak-render decode-session LRU evicts hardware sessions first (each pins a GPU surface pool — ~100 MB at 4K), so a full cache cannot exhaust video memory before the next open. - Worker pool count now factors GPU vram: per-worker budget = 1 GiB (1080p peak) scaled by pixel ratio + 256 MiB idle floor, 10% reserve of free vram; applied when hardware decoding is on (nvidia-smi query, None otherwise falls back to the RAM/CPU policy). - Dynamic pool resize: ProcessDispatcher::set_target_workers grows or retires workers; retiring ones stop claiming, drain their in-flight batch (future playback frames included), then exit naturally on the shutdown signal — no mid-work kill (30 s deadline only as a hung- decoder last resort). A retiring worker that dies re-queues its frames to surviving workers. Resizes are throttled to 2 s (a resolution burst merges; only the latest target applies) so 1080p<->4K flaps cannot thrash process spawns. - RenderManager::set_workspace_size announces the sequence resolution; RealEngine calls it from refresh_sequence_info. - Integration test: shrink 3->1 mid-wave (all frames complete, retired workers exit naturally) then regrow 1->3 and render a fresh wave.
Oak Video Editor 
Oak Video Editor is a free non-linear video editor for Windows, macOS, and Linux.
This project is a community-maintained fork of Olive Video Editor.
NOTE: Oak Video Editor is alpha software and is considered highly unstable. While we highly appreciate users testing and providing usage information, please use at your own risk.

Roadmap
| Version | Theme | Core Deliverables | Boundary Notes |
|---|---|---|---|
| 0.3 | Plugin Architecture Milestone | Production-ready OpenFX host support | Not about quantity of plugins, but "any OFX plugin loads without crashing" |
| 0.4 | Color, Audio & Performance | .cube/.3dl support, scopes (waveform/vectorscope/histogram), three-way color wheels, waveform auto-sync, BWF timecode sync, audio meters (LUFS/VU), proxy media workflow, hardware-accelerated export (NVENC/VideoToolbox), batch render queue |
Combines the previous 0.4-0.6 scope into one usability milestone: color workflow, audio sync, and 4K/8K performance |
| 0.5 | Animation, Tracking & Collaboration | Bézier keyframe curve editor, basic point tracking, image stabilizer, full multicam angle switching, OpenTimelineIO, EDL/XML import/export | Combines the previous 0.7-0.8 scope into one timeline/interchange milestone |
| 0.6 | Stability Milestone | Project file format freeze (backward compatibility promise), crash recovery, autosave, memory optimization | "Feature freeze" testing period before 1.0 |
| 1.0 | Production Ready | Complete documentation, installers, known issues list, community support channels | Declared "ready for serious projects" |
