On macOS versions before Sonoma (14.0), SCStreamConfiguration does not
support the captureMicrophone/microphoneCaptureDeviceID selectors. The
native helper was throwing a fatal error, blocking recording entirely
when microphone was enabled.
Now the Swift helper logs MICROPHONE_CAPTURE_UNAVAILABLE and continues
capture without microphone. The Node handler detects this signal and
returns microphoneFallbackRequired to the renderer, which starts a
browser-side MediaRecorder capturing the mic via getUserMedia. On stop,
the audio blob is saved as a .mic.webm sidecar alongside the native
recording, where the existing companion audio detection picks it up.
Fixes: 'Native microphone capture is unavailable on this macOS/Xcode
runtime' error on older macOS versions.
The Swift helper binaries were compiled with -target macos14.0, causing
dyld symbol-not-found crashes on macOS 13. The ScreenCaptureKit audio
APIs require macOS 13.0 minimum, so the deployment target is lowered to
13.0 and an #available guard is added for the macOS 14-only
ignoreShadowsSingleWindow API. README updated accordingly.
Fixes#199, fixes#200
- Call CoInitializeEx(MTA) at start of captureThread() and CoUninitialize() on exit
- Windows 11 enforces per-thread COM initialization more strictly than Win10,
causing GetBuffer/GetNextPacketSize to fail silently without this
- Add HRESULT error logging for WASAPI capture failures (GetNextPacketSize, GetBuffer)
- Add CGPreflightScreenCaptureAccess pre-check in Swift helper
- Add microphone TCC pre-flight when mic capture is requested
- Warm up TCC via desktopCapturer.getSources before spawning helper
- Request mic access from Electron before helper spawn
- Remove unreliable systemPreferences.getMediaAccessStatus pre-checks
- Add camera entitlements to plist files for webcam support
- Guard getScreen() calls behind app.isReady()
- Make tray icons lazy to avoid early screen access
- Suppress duplicate permission error alerts in renderer
- Hardened IPC with safety guards for all webContents.send calls
- Scrubbed sensitive absolute paths from caption logs
- Realigned Windows artifact naming logic
The WGC capture session uses Direct3D11CaptureFramePool::CreateFreeThreaded,
which dispatches FrameArrived callbacks on thread pool threads concurrently.
MFEncoder::writeFrame() accesses non-thread-safe resources (ID3D11DeviceContext,
IMFSinkWriter, shared staging texture and NV12 buffer) without synchronization,
causing MP4 container corruption when callbacks overlap at high frame rates.
Add a mutex to serialize writeFrame() and finalize() calls, preventing
concurrent access to the D3D context and Media Foundation sink writer.
Fixes#96
Add Electron IPC handlers and preload wiring for Whisper caption generation, small-model download management, and safer project media source resolution. Update native macOS capture helpers to mux separate system and microphone audio outputs before finalizing recordings.
Added `-target` flag to swiftc compilation to explicitly specify arm64-apple-macos14.0 or x86_64-apple-macos14.0 based on process architecture, ensuring proper binary compilation for darwin-arm64 native helpers.
Build a standalone C++ helper (same pattern as wgc-capture) that polls
GetCursorInfo() every 50ms and emits STATE:<type> to stdout — identical
protocol to the macOS Swift helper. Windows recordings now capture
correct cursor types (text, pointer, resize, etc.) instead of always
falling back to arrow.
- Use getRecordingsDir() instead of hardcoded RECORDINGS_DIR
- Fix stop order: video first, then audio save, then mux via new
mux-wgc-recording IPC
- Explicitly stop MediaStream tracks for audio resource cleanup
- Add native WASAPI audio capture (system loopback + mic) in C++ process
for sample-accurate sync; browser audio APIs crash with WGC
- Add window capture support (CreateForWindow) with window: source prefix
- Kill WGC capture process on app before-quit
- Add even-dimension guard in MFEncoder
- Fix ffmpeg asar path backslash handling on Windows
- Remove dead browser-side WGC audio code (storeWgcAudio IPC,
ScriptProcessorNode refs, stopWgcAudioCapture)
