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
- 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)
