Record captured frames with BT.709 conversion and explicit limited-range metadata. Share the Windows conversion code between capture engines and apply matching colour metadata on macOS and FFmpeg fallbacks.
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
- 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
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.
