Simplified the approach by removing complex callback logic and using a
simple 500ms timer-based update for the stats bar instead. This eliminates
threading errors completely while keeping the code straightforward.
Changes:
1. Removed queue change callback entirely
2. Added background timer that updates stats bar every 500ms
3. Removed initComplete flag (no longer needed)
4. Simplified setContent() to direct calls
5. Added onClearAll parameter to BuildQueueView()
6. Added ClearAll() method to Queue (removes all jobs)
7. Added Clear All button with DangerImportance styling in queue view
8. Clear Completed button now has LowImportance styling
This approach is much simpler: the UI just polls the queue state
periodically instead of trying to handle callbacks from goroutines.
No more threading errors, less code, easier to understand.

The threading errors were caused by queue callbacks triggering showMainMenu()
during app initialization, before the Fyne event loop was fully ready.
Changes:
1. Added initComplete flag to appState struct
2. Queue callback returns early if !initComplete, preventing UI updates
during initialization
3. Set initComplete=true AFTER ShowAndRun() would handle the event loop
4. Removed nested DoFromGoroutine() which was causing double-wrapping
5. Simplified setContent() to direct calls (no thread wrapping)
6. Callback properly marshals UI updates via DoFromGoroutine() after init
This ensures the queue callback only affects UI after the app is fully
initialized and the Fyne event loop is running.

The queue callback was triggering showMainMenu() from a goroutine (the
job processor) without marshaling to the main thread. This caused the
threading error "should have been called in fyne.Do[AndWait]".
Changes:
1. Queue callback now wraps all UI updates in app.Driver().DoFromGoroutine()
to safely marshal calls from the job processor goroutine to the main thread
2. setContent() now always uses DoFromGoroutine() to ensure thread safety
regardless of caller context. This prevents errors when called from
callbacks or other goroutines.
3. Added fallback for early initialization when app driver isn't ready yet
This ensures all UI updates happen on the main Fyne event loop thread.

Implemented three methods to add multiple videos to the queue:
1. **Drag from main menu**: When on the main menu, dragging multiple videos
onto the Convert tile automatically adds them all to the queue via
batchAddToQueue(). Already working - improved handling.
2. **Drag onto convert module**: When in the convert module, dragging
multiple video files now adds all of them to the queue instead of just
loading the first one. Single files are loaded as before.
3. **UI button support**: Added 'Add Multiple...' button next to 'Open File...'
to make it clear that users can load multiple files.
Changes:
- handleDrop(): Refactored to process all dropped files when in convert module
and call batchAddToQueue() for multiple videos
- buildVideoPane(): Added 'Add Multiple...' button and reorganized button
layout to show both single and batch options
This provides intuitive multi-file handling with three different workflows
for users who prefer different input methods.

- Remove queue loading at startup: Queue now starts completely fresh each
session. No Load() call from /tmp/videotools-queue.json
- Remove queue saving at shutdown: Queue is not persisted between sessions
- Delay callback registration: SetChangeCallback() is now called via
goroutine with 100ms delay to ensure UI is fully initialized before
callbacks can trigger showMainMenu()
- Keep simple setContent(): Direct calls to SetContent(), no threading
wrapper needed during normal operation
This ensures:
1. No threading errors on app startup
2. Clean empty queue on each new session
3. Proper initialization order preventing callback-during-init issues

This commit resolves three critical issues:
1. **Fyne Threading Error on Startup**: Fixed by improving setContent() to
check the initComplete flag. During initialization, setContent() calls
SetContent() directly since we're on the main thread. After initialization,
it safely marshals calls via app.Driver().DoFromGoroutine().
2. **Queue Persisting Between Sessions**: Fixed by removing queue persistence.
The shutdown() function no longer saves the queue to disk, ensuring a
clean slate for each new app session.
3. **Queue Auto-Processing**: Fixed by making the queue start in 'paused'
state. Users must explicitly click 'Process Queue' to start batch
conversion. Queue methods PauseProcessing() and ResumeProcessing()
control the paused state.
Changes:
- main.go: Added initComplete flag to appState, improved setContent()
logic, disabled queue persistence in shutdown()
- queue/queue.go: Added paused field to Queue struct, initialize paused=true,
added PauseProcessing()/ResumeProcessing() methods
- ui/queueview.go: Added UI controls for queue processing and clearing

Handle case where formatOption is loaded from JSON as a map instead
of a struct. This prevents panic when reloading saved queue on startup.

Previously, when a conversion was started and the user navigated away from
the Convert module and returned, the progress stats would freeze (though the
progress bar would continue animating). This was caused by the conversion
goroutine updating stale widget references.
Changes:
- Decoupled conversion state from UI widgets
- Conversion goroutine now only updates appState (convertBusy, convertStatus)
- Added 200ms UI refresh ticker in buildConvertView to update widgets from state
- Removed all direct widget manipulation from background conversion process
This ensures conversion progress stats remain accurate and update correctly
regardless of module navigation, supporting the persistent video context
design where conversions continue running while users work in other modules.
Advanced Mode Encoder Settings:
- Added full video encoding controls: codec (H.264/H.265/VP9/AV1), encoder preset,
manual CRF, bitrate modes (CRF/CBR/VBR), target resolution, frame rate,
pixel format, hardware acceleration (nvenc/vaapi/qsv/videotoolbox), two-pass
- Added audio encoding controls: codec (AAC/Opus/MP3/FLAC), bitrate, channels
- Created organized UI sections in Advanced tab with 13 new control widgets
- Simple mode remains minimal with just Format, Output Name, and Quality preset
Snippet Generation Improvements:
- Optimized snippet generation to use stream copy for fast 2-second processing
- Added WMV detection to force re-encoding (WMV codecs can't stream-copy to MP4)
- Fixed FFmpeg argument order: moved `-t 20` after codec/mapping options
- Added progress dialog for snippets requiring re-encoding (WMV files)
- Snippets now skip deinterlacing for speed (full conversions still apply filters)
Window Layout Fixes:
- Fixed window jumping to second screen when loading videos
- Increased window size from 920x540 to 1120x640 to accommodate content
- Removed hardcoded background minimum size that conflicted with window size
- Wrapped main content in scroll container to prevent content from forcing resize
- Changed left column from VBox to VSplit (65/35 split) for proper vertical expansion
- Reduced panel minimum sizes from 520px to 400px to reduce layout pressure
- UI now fills workspace properly whether video is loaded or not
- Window allows manual resizing while preventing auto-resize from content changes
Technical Changes:
- Extended convertConfig struct with 14 new encoding fields
- Added determineVideoCodec() and determineAudioCodec() helper functions
- Updated buildConversionCommand() to use new encoder settings
- Updated generateSnippet() with WMV handling and optimized stream copy logic
- Modified buildConvertView() to use VSplit for flexible vertical layout

- Implemented position-based drop detection on main menu module tiles
- Added detectModuleTileAtPosition() to calculate which tile receives the drop
- Modified window drop handler to pass position and route to appropriate module
- Bypasses Fyne's drop event hierarchy limitation where window-level handlers
intercept drops before widgets can receive them
- Only enabled tiles (currently Convert) respond to drops
- Loads video and switches to module automatically
Cover Art Embedding Fixes:
- Fixed FFmpeg exit code 234 error when embedding cover art
- Added explicit PNG codec specification for cover art streams
- Snippet generation: Added `-c✌️1 png` after mapping cover art stream
- Full conversion: Added `-c✌️1 png` for proper MP4 thumbnail encoding
- MP4 containers require attached pictures to be PNG or MJPEG encoded
Embedded Cover Art Extraction:
- Added EmbeddedCoverArt field to videoSource struct
- Extended ffprobe parsing to detect attached_pic disposition
- Automatically extracts embedded thumbnails when loading videos
- Extracted cover art displays in metadata section (168x168)
- Enables round-trip workflow: generate snippet with thumbnail, load snippet
and see the embedded thumbnail displayed
Technical Details:
- Modified handleDrop to accept position parameter
- Added Index and Disposition fields to ffprobe stream parsing
- Cover art streams now excluded from main video stream detection
- Grid layout: 3 columns, ~302px per column, ~122px per row, starts at y=100
- Embedded thumbnails extracted to /tmp/videotools-embedded-cover-*.png
