- playback timer uses the audio output device as its master clock: the
PortAudio callback counts consumed frames (including underrun
zero-fill) so video cannot drift away from what is heard; wall clock
remains as fallback when no clocked output is running
- output clock compensates for device output latency; new Preferences >
Audio buffer size setting (0 = auto)
- SampleBuffer::speed() now uses linear interpolation instead of
nearest-neighbor sampling
- regression tests: audio-clock driven timer (fwd/rev/speed), wall
clock fallback, interpolation correctness
Version is no longer hardcoded: at configure time CMake uses the tag
name when HEAD is exactly on a tag (leading "v" stripped), otherwise
the first 8 hex digits of the commit hash. When git is unavailable
(e.g. source tarball) it falls back to the contents of version.txt,
which is now the single place to bump the release version.
Also remove the temporary qDebug() flood in the audio playback path
(ViewerWidget::QueueNextAudioBuffer / ReceivedAudioBufferForPlayback,
AudioManager::PushToOutput).
Node core:
- MathNode/TrigonometryNode combo strings realigned with Operation enums
- mathbase scalar/vector operand pick no longer uses bitwise type checks
- NodeSetPositionAndDependenciesRecursively moves dependencies again
- RemoveAllKeyframes undo actually restores keyframes
- NodeGroup GetInputName null-deref guard, passthrough ids use input id
- NodeValueTable::Has is an exact type match; tag fallback only for
empty tags; kStrCombo/kPushButton get data type names
- delete_all_keyframes no longer loops forever on unparented keyframes;
keyframe-load failures propagate; rational interpolation falls back to
double; OpacityEffect no longer leaks its internal MathNode
Audio/footage:
- AudioVisualWaveform: GetSummaryFromTime underflow OOB read, TrimIn
prepend length bookkeeping, OverwriteSums source channel indexing
- PanNode inserts the pan value into the sample job (keyframed pan
works); OutputParamsChanged is emitted on device change; PortAudio
device indices are validated before Pa_GetDeviceInfo
- Footage: AdjustTimeByLoopMode no longer hangs/UBs on degenerate
lengths, GetStreamIndex bounds-checked, CheckFootage clears stale
state on missing files, failed probes are not cached,
FootageDescription::Load requires its own root element
Render/track:
- ViewerOutput pushes the tagged samples value; TrackList disconnects
the track-height lambda; GetTrackFromReference validity check
- RenderManager dummy backend: null-initialized threads, guarded
decoder-cache/timer paths; Renderer::Destroy releases color cache
shaders/textures; unknown dynamic backends no longer alias to oakgl
- SharedMemoryRegion POSIX attach validates segment size; ReadMessage
skips blank lines instead of failing; GC counter clamped;
IsRenderingCustomRange implemented; TimeOffsetNode gets a true
inverse OutputTimeAdjustment; zero-speed clips return the held frame
Plugin/nodes:
- OliveClip: stored default region of definition is honored, on-demand
images are cached; OliveHost sets host identity properties and logs
instead of showing modal dialogs offscreen; Plugin.h dead decls gone
- DespillNode guards graph-less use with Rec.709 fallback; description
typos fixed (despill, swirl); mosaic applies when only one axis
matches; Windows-only Project filename separator test fixed
- Waveform sync no longer treats uncached waveform regions as silence:
the envelope extraction now reports a per-window validity mask and the
correlation skips invalid windows on either side, improving accuracy
for partially cached clips
- Add stretch/speed sync: AudioWaveformSync::EstimateStretchAndOffset
searches a playback-rate range plus offset, and a new timeline
context action 'Synchronize by Waveform (Adjust Speed)' applies the
estimated rate as a clip speed change (with undo) when plain offset
alignment is inconclusive
- Footage properties dialog gains a Source Start Time field so the
value used by source-time sync can be viewed and edited manually
instead of relying solely on auto-detected metadata; applied via an
undo command, with Footage::ClearSourceStartTime() for removal
- Regression tests for masked correlation, stretch estimation, the
envelope validity mask, and source-start-time set/clear
Replace every direct FFmpeg call in the editor and the render worker
with the pure C ffmpeg_bridge API, wrapped in thin C++ adapters that
preserve the original interfaces:
- avframeptr.h: olive::AVFrame adapter around FBFrame handles
- ffmpegutils: format conversion helpers on FB_* constants; the int
overload is renamed GetCompatibleBridgePixelFormat to avoid a silent
overload-resolution trap with the PixelFormat enum
- ffmpegdecoder/ffmpegencoder: rewritten as handle-based adapters over
FBDecoder/FBProbe/FBEncoder/FBScaler/FBResampler
- audioprocessor: FBAudioGraph push/pull adapter
- pluginrenderer/OliveClip: sws/pixdesc usage converted to FBScaler and
fb_pix_fmt_* queries
- AudioParams/channel layouts are plain uint64_t masks everywhere
Build integration: the root project no longer links FFMPEG directly;
only ffmpeg_bridge does. Binaries resolve the bridge library at runtime
via @loader_path inside the macOS app bundle (copied there post-build)
and via $ORIGIN/../ffmpeg_bridge/bin on Linux; on Windows the DLL is
installed next to the executables, so packages on all three platforms
ship the bridge library.
ffmpeg_bridge gains the extra API the adapters need:
fb_frame_make_writable, fb_decoder_get_format_duration,
fb_resampler_convert_frame, FB_PIX_FMT_YUV440P, SRT validation in
fb_probe_read_subtitle_stream, packed/planar fixes in
fb_encoder_write_audio, and a component-size fix in
fb_pix_fmt_component_size.
- On Linux, automatically prefer PipeWire/JACK/PulseAudio over ALSA
even when a saved ALSA device name exists in config.
- Restore Footage length after deserialization so worker snapshots
have valid stream lengths and video playback can advance.
- Guard ResolveDecoderFromInput and ProcessAudioFootage against a
null decoder cache to prevent worker crashes on direct Footage ->
ViewerOutput connections.
- Keep Linux signal backtrace handler in the render worker.
- Add Oak project SVG logos.
- Add FixChannelLayout() helper to AudioProcessor::Open() to fall back to a
default native channel layout when the input/output layout is unspecified,
custom, or has a zero mask. This prevents FFmpeg's abuffer/aformat filters
from rejecting 'channel_layouts=0x0' on Linux.
- Log audio processor open parameters, viewer audio queue state, and
AudioManager::PushToOutput device/stream status to help diagnose silent
playback on Linux.
* Switch around Pa_Initialize and PaJack_SetClientName so that the jack
client is named "Olive" on the first initialization and not on
subsequent initializations when refreshing devices.
* Make use of pa_jack.h dependant on availability of the header and not
on the usage of the linux platform.

It's arguably not finished in that each API has parameters that users may want control over (e.g. ASIO latency), but it allows selecting devices again which is a necessity
