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
- Help > About Oak… opens a real dialog (was a placeholder print): name
+ version, the GPL-3.0 line, the Olive fork notice and the thanks to
Enzo GD (Community Promoter).
- Modal (gpui_widgets, submodule bump): a title-row close button on
every dialog and opt-in backdrop dismissal (dismiss_on_mask) — Help >
Search Actions and About use it, so they close on an outside click
(previously a buttonless modal could only be closed with Escape).
- Preferences general tab grows two live settings: the cache-ahead
pre-render window (PlaybackPreRenderFrames, consumed by the preview
scheduler every playback tick) and the library storage backend
(Storage/Backend sqlite/pg + Storage/PgUrl connection string, read by
oak-storage's write-through when a project binds; the pg URL field
shows only for PostgreSQL and commits on dialog close). The C++
auto-recovery toggle is skipped on purpose: the Rust snapshot loop
has no disable semantic, so the switch would be dead.
i18n keys for all eight packs; new tests cover the about modal and the
preferences writes.
The menu item was a placeholder print; it now opens a real dialog (the
C++ ProjectPropertiesDialog):
- Per-project OCIO config override with a 浏览… picker: validated on OK
(an invalid config keeps the dialog open with the error shown, like
the C++ accept()), persisted in the project settings, applied to the
display color pipeline on accept and on project open, and reverted to
the app default when the project closes. oak-render gains
set_up_default_config_from for the explicit-path load.
- Disk-cache location (default / alongside the project / custom path):
persisted through the OVE serializer (cachesetting/customcachepath
round-trip the settings map, clamped on load) and honored by the
thumbnail writer — the first live consumer of Project::cache_path.
- PathField gains an enabled state (the custom path field follows the
combo selection).
The C++ color tab's Default Input Color Space and Reference Space
combos are intentionally absent: the Rust render pipeline has no
consumer for them today (decode performs no input transfer conversion),
so showing them would be dead settings.
Tests: dialog opens, OK applies the cache location, an invalid OCIO
config keeps the dialog open with the error row. i18n keys for all
eight packs.
Three real-engine throughput loops (thumbnail pipeline, full-res fill
behind the proxy, playback window supply) failed on machine slowness:
their pass/fail was a wall-clock Instant deadline, so a loaded machine
broke them for speed, not for a broken pipeline. Each loop now counts
engine pumps — machine-speed independent — and asserts the condition
within a bounded number of pumps. The two single-frame worker channel
receives keep a generous 60 s recv_timeout (a one-shot bounded
operation, not a throughput loop).
oak-cli: the integration fixtures moved with the app crate during the
workspace restructure; point the fixture helpers at
../oak-app/tests instead of the (now empty) repo-root tests/.
New complete language packs (431 keys each, key-aligned with en-US):
French, German, Russian, Japanese, Spanish, Portuguese — contributed
via the translation subagent, reviewed for key parity and genuine
translations.
Runtime discovery replaces compiled-in packs: include_str! and the
Language enum are gone; every <code>.yaml found in the searched
directories registers a language, so adding one needs neither a
rebuild nor a code change. Each pack names itself via its
"language.name" key (the endonym), which the pickers display. The
menu bar language submenu is built from the discovered packs (menu ids
in the new LANG_ITEM_BASE range, dispatched before the registry), the
preferences combo enumerates them the same way, and switching goes
through set_language_code. The C++-style LangZh/LangEn registry
actions are removed (menu ids 303/304 stay reserved). pack_dirs gains
the system-install layout <exe>/../share/oak/i18n, and en.yaml is
renamed en-US.yaml so the discovered code matches the fallback code.
Test hardening (a Windows/Linux CI flake chain exposed by this work):
the two language-test mutexes are one shared poison-tolerant mutex;
every test that flips the process language restores en-US before
releasing it; tests that match menus by localized labels take the lock
and pin en-US first.
- Linux: libxkbcommon-x11-dev for the gpui X11 client link
- Windows: patch <cstdint> into the vendored yaml-cpp (a cached cmake
configure ignores CXXFLAGS; the patch is idempotent and runs after
cargo fetch)
- macOS: the hw-decode test skips its VideoToolbox engagement
assertions on hosts where VT cannot initialize (headless/virtualized
runners) instead of failing
- display color management: the display ICC (system or custom) is
applied to viewer frames at present time (F32 in place, or in place
on the BGRA staging copy with the R/B swizzle baked into the OCIO
chain); preferences get a Color section (mode + custom ICC file); on
macOS the Metal layer is tagged with the display colorspace when
self-managing so ColorSync passes pixels through (no double
correction); frame caches track the transform generation so a mode
or profile change drops stale pixels
- string tables live in assets/i18n/<lang>.yaml, loaded at runtime
(user pack dir ~/.oak/i18n, app bundle Resources/i18n, dev checkout)
with the compiled-in English/Chinese tables as fallback
- new status.proxy.on/off keys; inspector.params copy no longer says
"placeholder"; effect_library.group.builtin key
- bundle the packs as cargo-bundle resources; dev profile dep opt-level
dropped to 1 for faster iteration builds
- App no longer depends on the oakengine rlib: build.rs links the
built liboakengine.dylib (+rpath, -export_dynamic, IOSurface) and
src/oakui/ffi.rs declares the pure-C surface; RealEngine calls only
the frozen oakengine_* C ABI
- host_syms.rs provides the oakcore_*/fb_* host symbols the dylib
imports via dynamic lookup
- Fix Preferences dialog crash (spawn_modal reentrancy) with a
regression test
- Timeline toolbar and viewer transport render C++-era icons (16px
grid, dark/light themes) with localized tooltips
- i18n: complete en-US table, add untranslated-key detection test
- New dialogs module (preferences, export, progress)
