oak-common is gone; its modules (configstore, xmlutils, ocioutils,
oiioutils, colormath, colortransform, videoparams, ffmpegutils, ...)
now live in oak-core alongside the value types. The render value/GPU
types moved too: backend (wgpu context + DisplayRenderer), color
(ColorProcessor over ocio-rs), texture, frame, and the commonutil
config helpers.
Fix-ups to make the merged tree build and pass tests:
- oak-core Cargo.toml: wgpu back to 25 (the moved backend code is
written against that API generation); add the toml/quick-xml/image
deps oak-common carried.
- lib.rs: drop the duplicate 'pub mod error;'.
- error.rs: unified OAKCORE_* codes; restore Error::new() and
From<OcioError> from oak-common's error type.
- backend.rs/color.rs: oak_core::/oak_render:: self-references
rewritten to crate::; the shaderfx-dependent GPU effect test moved
to oak-render's shaderfx tests (shaderfx depends on oak-node and
cannot live in oak-core).
- oak-render's error module re-exports oak_core::error::{Error,
Result}; the OAKRENDER_* codes stay as the public-code contract.
- oak-node jobs.rs: ColorProcessor imported from oak_core::color.
- Integration tests repointed at oak_core::{texture, frame, backend,
color, colormath}.
- the display-ICC regression test treats an empty OAK_DISPLAY_ICC as
unset, matching displayicc::env_override_icc.
Proxy generation no longer pegs the machine:
- the transcode probes for a hardware H.264 encoder once per process
and uses it when present (macOS h264_videotoolbox; Windows/Linux
h264_nvenc -> h264_qsv -> h264_amf; libx264 remains the universal
fallback and the untouched C++ parity path), with decode-side
-hwaccel auto (HEVC 4:2:2 10-bit decodes in hardware on Apple
Silicon / RTX 50+ / Intel GPUs and falls back to software cleanly);
quality/preset map from the proxy CRF/preset per encoder
- the concurrency limit is configurable (ProxyMaxConcurrent, default
1) in the Proxy Settings dialog; auto-generated jobs queue and the
next starts when a slot frees. The invariant
concurrency x per-job threads <= logical cores / 2 holds by
construction (thread budget = half the cores / concurrency, clamped
to [1,8], covered by a unit test), and on Unix ffmpeg runs nice -n 10
so the background task never starves the foreground
- deleting a footage's proxy also removes it from the auto-generation
queue
With the global proxy switch on, footage that needs a proxy now gets
one generated in the background automatically — on import, on project
open, and when proxy use is enabled for a footage — instead of only
through the manual Generate menu action. Footage explicitly opted out
(a recorded proxy path with use disabled) and footage whose last
generation failed are not restarted; the generation path enables proxy
use so preview switches to the proxy as soon as it is ready.
The bin shows the lifecycle as a corner badge on each footage entry
(green P = ready, amber P = generating, red ! = failed; the widget
half lives in the gpui fork, submodule bumped here).
Includes a real-media test driving ProxyTask end-to-end on 4K H.265
4:2:2 10-bit (the media class the 4K playback lag was reported on):
180 s transcodes to a 720p proxy in ~25 s.
All crates take the oak-* kebab-case naming (oak-audio, oak-codec,
oak-common, oak-core, oak-ffmpeg-link, oak-node, oak-otio, oak-plugin,
oak-render, oak-storage, oak-task, oak-timeline, oak-undo), with the
lib identifiers rewritten (oakrender:: -> oak_render::, oakcore_rs:: ->
oak_core::, ...) across all 226 referencing files.
The GUI application moves from the workspace root into
crates/oak-app/: src/, build.rs (paths fixed for the new location) and
tests/ travel with it, the root Cargo.toml becomes workspace-only
([workspace] + workspace.package + profiles), and the app package
inherits the workspace version. The screenshots example becomes a
standalone crate examples/simple_player/ with its own Cargo.toml.
Every crate now inherits the single workspace version
(version.workspace = true), and the workflows' crate paths and the
build docs follow the renames.
Validated with a clean cargo check --workspace.
