mpv embedding:
- Replace wid/QOpenGLWidget with QOffscreenSurface + QOpenGLFramebufferObject
+ QPainter readback — works on Wayland/KDE without sub-surface compositing
- Force desktop OpenGL 3.3 core profile before QApplication (fixes black output on GLES)
- Timer-based render polling (16 ms) replaces signal-flood from mpv C thread;
fixes playback animation and scrubbing preview
- Fix AB-loop: set ab-loop-a/b to "no" on stop (0 means infinite in mpv)
Timeline:
- Full redesign: time ruler with adaptive major/minor ticks, playhead triangle
handle, selection region with edge lines, numbered marker badges
- Height 160 px; layout collapsed from 4 rows to 2 below timeline
- Markers appear immediately on export (optimistic update before ffmpeg finishes)
- Right-click marker → context menu to delete from DB
Hotkeys:
- Replace keyPressEvent with QShortcut(ApplicationShortcut) so keys work
regardless of focused widget; MpvWidget gets NoFocus policy
Export:
- WebP: switch lossless→lossy quality 85, compression_level 1 (~10x faster)
- Add -threads 0 for full CPU utilisation during decode/filter
- Remember last export folder across sessions via QSettings
