Changed filename row to use VBox layout instead of HBox to give
it full width. This prevents the filename from wrapping at every
character. Removed wrapping from other metadata fields since
they're short values that don't need it.
Enabled word wrapping for all value labels in the metadata panel
to prevent text cutoff. Long filenames and metadata values will
now wrap to multiple lines instead of being truncated.
Changed from HBox with spacer to GridWithColumns for better
column alignment. This prevents the right column (Video Codec,
etc.) from being pushed too far to the right edge.
When users click on modules with missing dependencies (orange tiles),
show a dialog listing the missing dependencies and their install
commands. This helps users quickly identify what they need to install
to enable the module.
Modules with handlers but missing dependencies now show orange
background with stripes instead of grey. This distinguishes them
from unimplemented modules (grey) and helps users identify what
needs to be installed.
Set Trim, Audio, and Blu-Ray module handlers to nil to mark them
as disabled. These modules show as grey tiles with lock icons and
diagonal stripes until they are implemented.
Settings remains enabled despite nil handler as it has functionality.
Changed module colors to work better with white text:
- Trim: #FFEB3B → #F9A825 (dark yellow/gold)
- Audio: #FFC107 → #FF8F00 (dark amber)
- Subtitles: #8BC34A → #689F38 (dark green)
All modules now use consistent white text for uniform appearance.
Fixed filename overlapping with video codec information:
- Moved filename to its own full-width row at the top
- Two-column grid now starts below filename
- Prevents long filenames from overlapping with right column data
- Improves readability of metadata panel
This addresses the issue where long filenames like "She's So Small 12 Scene 3 Dillion Harper.mp4" would run into "Video Codec: h264" on the same line.

Add comprehensive Settings module for managing system dependencies and application preferences:
- Created settings_module.go with dependency checking system
- Maps modules to required dependencies (FFmpeg, DVDAuthor, xorriso, Real-ESRGAN, Whisper)
- Displays dependency status with visual indicators (green/red)
- Shows platform-specific installation commands
- Auto-enables/disables modules based on installed dependencies
- Added Settings tile to main menu (always enabled)
- Integrated module availability checking via isModuleAvailable()
This provides users a centralized location to check and install missing dependencies, addressing the requirement to disable modules when dependencies aren't available.

Added a "Cancel Job" button to the Author module top bar that:
- Appears only when an Author job is currently running
- Uses DangerImportance styling for clear visual indication
- Cancels the running author job when clicked
- Hides automatically when no author job is running
This addresses the user's request for cancel buttons in every module
where it's relevant. The button provides immediate job cancellation
without needing to navigate to the queue view.

Investigation revealed:
- Player module is ALREADY fully internal and lightweight
- Uses FFmpeg directly to decode video frames and audio
- Uses Oto library (lightweight Go audio library) for audio output
- No external VLC/MPV/FFplay dependencies
Implementation:
- FFmpeg pipes raw video frames (rgb24) directly to UI
- FFmpeg pipes audio (s16le) to Oto for playback
- Frame-accurate seeking and A/V sync built-in
- Error handling: Falls back to video-only if audio fails
Previous crash was likely from:
- Oto audio initialization failing on your system
- OR unrelated issue (OOM, etc.)
- Code already handles audio failures gracefully
Player module is safe to re-enable - it follows VideoTools' core principles.

Issue:
- User reported batch settings text being cut off
- "Settings persist across videos. Change them anytime to affect all sub"
- Text truncated instead of wrapping to next line
- Cache directory hint also had truncation issues
Root Cause:
- settingsInfoLabel didn't have TextWrapWord enabled
- cacheDirHint had TextWrapWord but wasn't in a sized container
- Labels in VBox need padded containers for wrapping to work properly
Solution:
- Enabled TextWrapWord on settingsInfoLabel
- Wrapped both labels in container.NewPadded() containers:
* settingsInfoContainer: "Settings persist across videos..." text
* cacheDirHintContainer: "Use an SSD for best performance..." text
- Replaced direct label usage with containers in settingsContent VBox
Affected Labels:
- settingsInfoLabel: Batch settings persistence explanation
- cacheDirHint: Cache/temp directory usage guidance
Implementation:
- Added TextWrapWord to settingsInfoLabel

- Text truncated with "or s" visible, rest cut off
- Hint labels weren't wrapping properly in narrow windows
Root Cause:
- Hint labels had TextWrapWord enabled BUT
- Labels inside VBox containers don't wrap properly without width constraints
- Fyne requires labels to be in a sized container for wrapping to work
- VScroll container doesn't provide width hints to child labels
Solution:
- Wrap all hint labels in container.NewPadded() containers
- Padded containers provide proper sizing context for text wrapping

Critical Fix:
- Goroutine dump showed hundreds of leaked animation goroutines
- Each queue refresh created NEW progress bars without stopping old ones
- Animation goroutines continued running forever, consuming resources
Root Cause:
- BuildQueueView() creates new StripedProgress widgets on every refresh
- StartAnimation() spawned goroutines for running jobs
- Old widgets were discarded but goroutines never stopped
- Fyne's Destroy() method not reliably called when rebuilding view
Solution:
- Track all active StripedProgress widgets in appState.queueActiveProgress
- Stop ALL animations before rebuilding queue view
- Stop ALL animations when leaving queue view (stopQueueAutoRefresh)
- BuildQueueView now returns list of active progress bars
- Prevents hundreds of leaked goroutines from accumulating
Implementation:
- Added queueActiveProgress []*ui.StripedProgress to appState
- Modified BuildQueueView signature to return progress list
- Stop old animations in refreshQueueView() before calling BuildQueueView
- Stop all animations in stopQueueAutoRefresh() when navigating away
- Track running job progress bars and append to activeProgress slice

This commit introduces several enhancements to the Author module:
- **Real-time Progress Reporting:** Implemented granular, real-time progress updates for FFmpeg encoding steps during DVD authoring. The progress bar now updates smoothly, reflecting the actual video processing. Progress calculation is weighted by video durations for accuracy.
- **Add to Queue Functionality:** Added an 'Add to Queue' button to the Author module, allowing users to queue authoring jobs for later execution without immediate start. The authoring workflow was refactored to accept a 'startNow' parameter for this purpose.
- **Clear Output Title:** Modified the 'Clear All' functionality to also reset the DVD Output Title, preventing accidental naming conflicts for new projects.
Additionally, this commit includes a UI enhancement:
- **Main Menu Categorization:** Relocated 'Author', 'Rip', and 'Blu-Ray' modules to a new 'Disc' category on the main menu, improving logical grouping.
Fixes:
- Corrected a missing argument error in a call to .
- Added missing import in .
Updates:
- and have been updated to reflect these changes.
Problem: Author log was causing severe UI lag and memory issues
- Unbounded string growth (entire log kept in RAM)
- Full widget rebuild on every line append
- O(n²) string concatenation performance
Solutions implemented:
1. Tail behavior - Keep only last 100 lines in UI
- Uses circular buffer (authorLogLines slice)
- Prevents unbounded memory growth
- Rebuilds text from buffer on each append
2. Copy Log button
- Copies full log from file (accurate)
- Falls back to in-memory log if file unavailable
3. View Full Log button
- Opens full log in dedicated log viewer
- No UI lag from large logs
4. Track log file path
- authorLogFilePath stored when log created
- Used by copy and view buttons
Performance improvements:
- Memory: O(1) instead of O(n) - fixed 100 line buffer
- CPU: One SetText() per line instead of concatenation
- UI responsiveness: Dramatically improved with tail behavior
UI changes:
- Label shows "Authoring Log (last 100 lines)"
- Copy/View buttons for accessing full log
Improvements:
1. Track audio active state with atomic.Bool flag
2. Handle videos without audio track gracefully
- If audio fails to start, video plays at natural frame rate
- Clear error messages indicate "video-only playback"
3. Better A/V sync logging for debugging
- Log when video ahead/behind and actions taken
- Log good sync status periodically (every ~6 seconds at 30fps)
- More granular logging for different sync states
4. Proper cleanup when audio stream ends or fails
How it works:
- audioActive flag set to true when audio starts successfully
- Set to false when audio fails to start or ends
- Video checks audioActive before syncing to audio clock
- If no audio: video just paces at natural frame rate (no sync)
- If audio active: full A/V sync with adaptive timing
Expected improvements:
- Video-only files (GIFs, silent videos) play smoothly
- Better debugging info for sync quality
- Graceful degradation when audio missing

Priority 3 fix from PLAYER_PERFORMANCE_ISSUES.md - addresses the root
cause of A/V desync in player module.
Changes:
- Audio loop now tracks bytes written and updates master clock (audioTime)
- Audio clock calculation: bytesWritten / (sampleRate × channels × bytesPerSample)
- Video loop already syncs to audio master clock (from previous commit)
- Master clock updates happen after each audio chunk write
How it works:
- Audio is the timing master, plays at natural rate
- Video reads audio clock and adapts timing to stay in sync
- If video >3 frames behind: drop frame and resync
- If video >3 frames ahead: wait longer
- Otherwise: adjust sleep duration for gradual sync
Expected improvements:
- Rock-solid A/V sync maintained over extended playback
- No more drift between audio and video
- Adaptive recovery from temporary slowdowns
Combined with Priority 1 (larger audio buffers) and Priority 2 (FFmpeg
volume control), this completes the core A/V sync architecture.

- Behind < 0: Sleep until next frame (ahead of schedule)
- Behind > 3 frames: Drop frame and resync (way behind)
- Behind > 0.5 frames: Catch up gradually (moderately behind)
- Otherwise: Maintain normal pace
Performance Improvements:
- Audio: No more per-chunk volume processing overhead
- Video: Adaptive timing handles temporary slowdowns
- CPU: Significant reduction in audio processing load
- Smoothness: Better handling of system hiccups
Testing Notes:
- Audio stuttering should be greatly reduced
- Volume changes have ~200ms glitch during restart
- Frame drops logged every 30 frames to avoid spam
- Works with all frame rates (24/30/60 fps)
Still TODO (Priority 3):
- Single FFmpeg process for perfect A/V sync
- Currently separate video/audio processes can drift

Refactoring:
- Create inspect_module.go (292 lines)
- Move showInspectView() and buildInspectView()
- Reduce main.go from 14,329 to 14,116 lines (-213 lines)
- Reduce main.go from 426KB to 420KB
This is the first step in modularizing main.go to improve:
- Windows build performance (currently 5+ minutes)
- Code maintainability and organization
- Following established pattern from author_module.go and subtitles_module.go
Remaining modules to extract:
- player, compare, thumb, filters, upscale, merge, convert, queue, benchmark

Seeking Fixes:
- Remove debouncing delay for immediate response
- Progress bar now seeks instantly when clicked or dragged
- No more 150ms lag during playback navigation
Frame Stepping Fixes:
- Calculate current frame from time position (current * fps)
- Previously used frameN which resets to 0 on every seek
- Frame stepping now accurately moves ±1 frame from actual position
- Buttons now work correctly regardless of seek history
Technical Details:
- currentFrame = int(p.current * p.fps) instead of p.frameN
- Removed seekTimer and seekMutex debouncing logic
- Immediate Seek() call in slider.OnChanged for responsive UX
