Mike-Solar 35b9ad9541 feat(oakcodec): hardware video decoding by default on all platforms
FFmpeg 8 removed the standalone hardware decoders (h264_videotoolbox/
vaapi/nvdec/d3d11va no longer exist in its configure) — hardware decode
now only exists as a hwaccel attached to the software decoder. The new
oakcodec::hwdecode module therefore opens the regular decoder with the
platform's hardware device context attached (VideoToolbox on macOS,
VA-API then NVDEC on Linux, D3D11VA then NVDEC on Windows): FFmpeg
engages the matching hwaccel, decodes into hardware surfaces, and we
transfer them to system memory (NV12/P010) ahead of swscale.

- HardwareDecoding config switch, default ON by mandate; a checkbox in
  Preferences > Rendering (EN/ZH); device creation failure skips to the
  next candidate and finally to software; a decode-time failure on a
  hardware session reopens it as software and retries once.
- hw_decoder_name() observability hook plus a HW_TRANSFERS counter so
  tests can prove the hwaccel really engaged (not silently software).
- Verification: demo.mp4 H.264 decodes through VideoToolbox with a
  transferred hardware surface, and the pixels match the software
  decode within 0.05; switch off forces software.
- build-ffmpeg.sh also enables nvdec when ffnvcodec headers exist.

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"
