- Add GitHub Actions workflow with build jobs for: - Native Vala/Meson build and tests - GNOME Flatpak (GTK4, GNOME Platform 46) - KDE Flatpak (GTK4 on KDE Platform 6.7) - Legacy Flatpak (GTK3, for X11 compatibility) - Add GTK4/Wayland Flatpak manifest (flatpak-gtk4.yml): - Uses xdg-desktop-portal for screen capture - Works on both GNOME and KDE Wayland - Updated ffmpeg 6.1, gifski 1.14.4 - Add KDE-specific Flatpak manifest (flatpak-kde.yml): - Builds GTK4 + libadwaita on KDE runtime - Native KDE Wayland support via portal - Add architecture document (docs/PEEK2_ARCHITECTURE.md): - Preview-based UI design (replaces transparent overlay) - Portal + PipeWire + GStreamer pipeline design - Module structure and migration plan - Platform support matrix
New capture module (src/capture/): - portal-session.vala: xdg-desktop-portal ScreenCast integration - Works on GNOME Wayland, KDE Wayland, and X11 via portal abstraction - Handles session lifecycle, source selection, PipeWire stream setup - region.vala: Crop region struct with scaling/clamping utilities New UI module (src/ui/): - preview-window.vala: Main GTK4/libadwaita window with live preview - Displays PipeWire stream in GtkPicture - Source selection, record/stop controls, format dropdown - crop-overlay.vala: Interactive crop selection widget - Draw-to-select with drag handles for resize - Semi-transparent overlay outside selection - Cursor changes for different drag modes New encoding module (src/encoding/): - pipeline.vala: GStreamer pipeline for recording - pipewiresrc → videocrop → encoder → filesink - WebM (vp9enc), MP4 (x264enc), GIF (frame extraction) - gifski integration for high-quality GIF output Build configuration: - meson-gtk4.build: New build file for GTK4 dependencies - gtk4, libadwaita-1, libportal-gtk4 - gstreamer-1.0, gstreamer-plugins-base-1.0
- Lower GTK4 requirement to 4.6 (Debian bookworm has 4.8) - Lower libadwaita requirement to 1.2 - Replace unavailable APIs (FileDialog, AlertDialog, content_fit) - Fix GVariant building for portal D-Bus calls - Fix Gdk.RGBA initialization (float vs double) - Document capture backends: x11grab for X11, portal for Wayland - Document per-platform prerequisites (minimal for X11, full stack for Wayland) - Restrict portal to monitor capture only (window capture misses popups)
…ements
- Add CaptureBackend interface with X11GrabBackend and PortalBackend implementations
- X11: FFmpeg x11grab with full desktop or single monitor selection
- Wayland: Portal + PipeWire capture (monitor only, window capture disabled)
- Add monitor dropdown for X11 ("Full Desktop" + individual monitors)
- Improve crop overlay with visible frame (green/cyan with dark outline)
- Add 4px margin to default selection so frame is always visible
- Reduce preview framerate to 2fps to minimize CPU from recursive capture
- Add environment diagnostics logging (GTK version, session type)
- Document refactor progress in docs/REFACTOR_PROGRESS.md
