Adjustment layers (docs/zh/plans/adjustment-layers-and-transitions.md):
a new timeline block type whose effect chain grades the composite of
every video track below it, over its own range (spanning clips or a
slice of one). The graph path flushes the lower tracks at the block's
track boundary and sweeps the composite through the chain via a
transient texture-source node; the montage path mirrors it with
AdjustmentSpan tickets (wire-compatible), so worker previews and
exports agree. An empty-area context menu creates one; the block
trims/moves/deletes like a clip, with undo everywhere.
Transitions: seam blocks come alive - cross dissolve/fade/wipe/slide
evaluate both neighbors through the graph path with progress from the
transition's own range (never the whole clip). Ctrl+Shift+D or the clip
menu inserts a default transition; the gpui wedges render and drag to
resize offsets undoably, and TransitionRemoveCommand now restores
offsets and edges on undo. The transitionfx node form runs the same
shaders on an adjustment layer with progress_in auto-filled from the
layer's span (explicit value wins).
Also: every built-in effect name and parameter name is now
translatable (360 node.* keys per locale, zh-CN fully translated, two
coverage tests guard future gaps); the new nodes register in
nodes/mod.rs with the factory smoke table updated; textfootage and
adjustment-layer i18n keys included.
retrieve_audio_to decodes whole codec frames but copies only the part
inside the requested chunk; the tail of the frame crossing the chunk end
(up to 1023 samples for AAC) was consumed by the decoder and lost, so
the next chunk started with a hole. On the playback grid (1920 samples
at 25fps/48kHz) the hole cycles 128..896 samples and hits 7 of 8 chunk
starts -- the heavy stutter/noise heard during playback.
Keep the overflow (decode and resampler-flush tails) in a per-session
carry buffer and serve it at the start of the next contiguous chunk;
clear it on seek, format change and chunk failure. Also make seek()
actually drop the cached resampler as its comment claimed.
Verified sample-exact: chunked decode of a 440Hz tone now matches a
one-shot decode bit for bit, and chunked renders of real media line up
with the ffmpeg CLI reference at correlation 1.0 / drift 0.
Adds a regression test (playback_sized_chunks_match_oneshot_sample_exact)
with a new tone fixture -- demo.mp4's audio is -90dB digital silence and
cannot expose the holes -- plus a render_audio_wav example used to
diagnose chunk-boundary artifacts offline.
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.
