All four are undoable and reuse the timeline/ command classes verbatim
(BlockSplitCommand, TrackRippleRemoveAreaCommand, BlockTrimCommand,
ReplaceBlockWithGap+PlaceBlock), with undo/redo assertions covering
split halves, media-in alignment on trim, ripple shift amounts, and
full restoration on undo
- oakengine_export_render drives ExportTask synchronously (offline
render + encode) with a progress callback, codec probing, and a
thread-local error channel; exporter.h keeps clear of the visibility
macro header
- oak-cli transcode now defaults to mp4 (H.264/AAC) with --format ppm
keeping the raw output path
- two real concurrency bugs found by the facade's own test: ExportTask
deadlocks when start()ed synchronously (queued conform handshake
needs an event loop), and the progress callback must be captured by
value because it fires on the task thread
- oakengine_sequence_add_track and add_footage_clip are the facade's
first editing primitives: undoable track creation and clip placement
with full range validation, clip enumeration, and gap filtering
- oak-cli transcode closes the loop: media file -> import -> clip ->
render, producing scaled PPM frames and a WAV from just the C ABI
- engine fix uncovered by transcode: the render worker used an invalid
empty AudioParams for IPC render frames, crashing any sequence that
contains audio; it now derives them from the rendered node itself
- sequence_new hardens its defaults against missing audio config keys
- oakengine_footage_probe inspects media without a project (decoder
probe): stream counts, per-stream video info (dimensions, rate,
duration, color tags, interlacing), audio info, duration, decoder
name, source start time; thread_local last_error for the NULL-handle
failure paths
- oakengine_project_import_footage adds probed footage to a project
through the same undoable command path as the app
- oak-cli probe prints decoder/duration/per-stream details and runs as
a ctest everywhere (no GL)
- dual ownership documented: probe handles are owned, imported footage
is borrowed from its project
- oakengine_sequence_get_video_params (width/height/pixel aspect) with
assertions for the default 1920x1080 square-pixel sequence and the
invalid-handle path
- oak-cli now renders at the sequence's real dimensions instead of the
hardcoded 1920x1080
- oak-cli info prints project/sequence/footage details; oak-cli render
writes PPM frames and a PCM WAV through the facade only - no engine
C++ headers, no Qt headers, links just liboakengine
- exit code 2 marks rendering-unavailable so ctest can skip cleanly on
machines without a GL render backend; info test runs everywhere
- facade fix uncovered by the CLI: project load now absolutizes the
path, so relative footage paths can't be mistaken for a moved
project; the fixture project now carries probed footage wired into
its sequence so it renders real content
- packaged like the other binaries (Linux bin install, macOS bundle,
Windows DLL copies); DESTDIR-verified
- oakengine_renderer_create/set_mode/last_error, render_frame (sync,
60s timeout, CPU frames via the existing worker pool),
render_audio (planar float), cancel; frames and audio buffers are
owned handles with borrowed data pointers
- output colorspace names map to OCIO display transforms, with
graceful fallback to reference-space output
- oakengine_renderer_test: parameter validation and error paths need
no GL and always run; render assertions gate on
DynamicRenderer backend availability and SKIP cleanly otherwise
- fix a facade bug found by its own test: wait_for_ticket leaked a
connected lambda capturing a stack reference, which a subsequent
cancelled ticket could fire into reused stack memory
- oakengine/export.h establishes the OAKENGINE_API visibility macros;
include/oakengine/ipc.h is the first pure-C surface (41 functions:
shm, frame slot pool, and the worker IPC messages as POD<->JSON
build/parse), implemented in engine/src/capi/
- the IPC implementations move to engine/src/oliveimpl (namespace
olive::engine::internal::ipc); engine/render/ipc/*.h are rebuilt as
same-name/same-API wrapper classes forwarding across the C boundary
- FrameSlotMeta is shared with the C header verbatim so the app/worker
wire format (v1) is bit-identical; static_asserts pin sizeof and
field offsets
- spscringbuffer.h moves to include/oakengine/ as an inline-only
header (no symbols, not ABI)
- new pure-C test oakengine_ipc_test (make_oakengine_test, no GL)
covers shm, frame pool, message round-trips and the layout asserts;
full gtest suite stays green (1986 tests)
Physical split: app/{audio,cli,codec,common,config,node,pluginSupport,
render,task,timeline,undo,tool,shaders} plus coreengine, version and
ui/icons+colorcoding move to a new top-level engine/ tree, built as
liboakengine.so (shared). The render backends (oakgl/oakvulkan) move
with it and link the engine library instead of embedding a static
render-core subset (libolive-rendercore is gone).
- oak-render-worker now links liboakengine instead of the whole
libolive-editor object set: 336MB -> 2.9MB, no Qt Widgets UI
- the editor links liboakengine for the engine and keeps only UI
objects in libolive-editor
- install/packaging: GNUInstallDirs libdir on Linux, bundle copy on
macOS, oakengine.dll staged for NSIS, AppImage validation entry
- fix backend lookup for the new layout: DynamicRenderer searched
../app but backends now live in engine/; a stale pre-split liboakgl
in the build tree got dlopened instead, re-initialized and later
destroyed the interposed engine statics (full-suite segfault at
DialogSequenceParameterTab, found via gdb watchpoint)
