Adds VAAPI DMA-BUF, D3D11VA shared-handle and VideoToolbox IOSurface imports behind a tri-state outcome (imported / unsupported / failed), planar textures with bounded residency and a CPU staging fallback, the staged montage decode path, reference-counted decoder frames, VAAPI-first device selection on Linux, and the host-GPU context plumbing used by the app and worker. See docs/zh/plans/render-pipeline-threads.md (M5).
oakcore-rs — Rust value-type foundation for the oak Rust modules
Status: declaration draft for review (no implementation, not wired into any build). Companion to
crates/oaknodeandcrates/oakrender.
Rust reimplementation of the oakcore C++ value types that cross every
module boundary: Rational, TimeRange, TimeRangeList, pixel/sample
format enums. These are pure data types with value semantics — the one
place where duplicating the C++ layout discipline in plain Rust is both
safe and required (a Rust crate cannot hold C++ objects by value).
Rules:
- Bit-exact arithmetic compatibility with
olive::core::Rational(reduction, overflow behavior, comparison) — the golden rule is the C++ test-suite semantics, not "ideal" rational math. #[repr(C)]only where a type crosses the C ABI; everything else is plain Rust withCopy + Clone + Eq + Hash.- No I/O, no allocation in arithmetic paths, no panics on degenerate input (denominator zero follows the C++ sentinel semantics).
