- Preview Sync button builds a short (8s) lossless clip around the
marked events with the current offset applied, and plays it in a
small popup PreviewDialog (its own independent PlayerWidget/mpv
instance) -- lets you check the fix sounds/looks right before
committing to a full export. ExportWorker gained optional
clip_start/clip_duration so both the real export and this preview
share the same underlying export_synced() call.
- Detect All Claps is back as a button in the Sync markers panel
(alongside Mark Audio/Video Event), in addition to staying in the
Tools menu -- both widgets' enabled state are kept in sync.
- Sync markers panel now shows Mark Audio Event before Mark Video
Event.
The clip-mode branch of ffmpeg_export.py (the -ss/-t-on-both-inputs
path ffdelay's own notes flag as easy to get subtly wrong) hadn't been
covered by the existing roundtrip test, which only exercised full-file
export -- added a clip-mode case there, independently verified via the
same scene-change/silence-detection technique as the other cases:
29.4ms drift after the fix, well under one frame.
All of this was built and verified entirely on a virtual Xvfb display
(DISPLAY=:99) per the user's request to stop interrupting their real
desktop -- real mouse clicks and a real (non-monkeypatched) preview
dialog were exercised there, screenshotted, and confirmed correct,
without ever touching the real screen.
- Clap detection moved from inline buttons to a Tools menu, plain labels
(no more '(whole file)' / '(from cursor)' parentheticals) -- status
messages moved to the window's status bar since the dedicated label
widget went away with the button row.
- ClickableSlider subclass: clicking anywhere along the seek track jumps
straight there instead of QSlider's default page-by-a-step behavior;
reposition-then-delegate-to-super keeps native drag behavior intact.
- Dragging now seeks live via sliderMoved instead of waiting for
sliderReleased.
- PlayerWidget accepts drag-and-drop of a local file to load it.
Verified with real Qt events (QMouseEvent clicks, a QDropEvent, a real
mouse click via xdotool opening the Tools menu on an actual running
window) rather than just calling the underlying methods directly.
