OpenScreen Studio v0.3.0

Changelog

Recording & capture

• Multi-track recording — screen mp4 plus optional sidecars:
  • System audio and microphone → sidecar WAVs via ScreenCaptureKit (audio_tap.rs)
  • Webcam → sidecar movie via AVFoundation (camera.rs)
• Native device enumeration — cameras and mics listed without parsing ffmpeg output
• CaptureAVSettings — HUD passes systemAudio, micDeviceId, and cameraDeviceId into start_capture
• AV toggles start off every launch; only chosen device IDs persist in localStorage
• Per-toggle TCC checks for camera, microphone, and screen recording, with links to the right Privacy pane
• Pause/restart segment concat — bundled ffmpeg stitches segments on stop
• Rust backend refactor — monolithic lib.rs split into capture, picker, permissions, editor, project, export, camera, and audio_tap

HUD & pre-record UI

• HudWindow — dedicated HUD phase machine (idle → countdown → recording) with window resizing per phase
• Configurable countdown — gear menu: off / 3 / 5 / 10 seconds (persisted); countdown pill with cancel and “Continue now”
• Floating webcam preview — camera-preview window via CameraPreview.tsx (getUserMedia, matched by device label)
• Redesigned source pills — camera / mic / system toggles with device pickers when multiple devices exist
• HudIco — separate icon set for HUD windows
• Close (✕) behavior — quits the app unless the editor is open (then hides the HUD)

Editor

• Sidecar audio tracks — system and mic with trimming, waveforms, and Web Audio preview playback
• Camera bubble — position/size keyframes; GPU compositing via new compositorGL.ts
• Project format v2 — saves audio-track and camera-bubble state
• .openscreen file association — Finder icon, UTI, and double-click to open projects

Export

• Rust export pipeline (export.rs) — frame streaming, ffmpeg encode/mux, path picker, clipboard copy
• Export dialog updated for multi-track audio and camera settings

Permissions & platform

• New commands: check_camera_access, request_camera_access, check_mic_access, request_mic_access, open_privacy_settings
• Info.plist — camera/microphone usage strings and document-type declarations for .openscreen

Docs & tooling

• README — clearer macOS “first open” steps for notarized builds
• AGENTS.md — updated architecture, capture flow, and module layout
• New Rust deps: hound, objc2-av-foundation, block2
