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:
- Player module was crashing when accessed
- Uses external tools (MPV, VLC, FFplay) which violates VideoTools' core principle
- Everything should be internal and lightweight, no external dependencies
Fix:
- Disabled Player module in main menu
- Module still exists in code but is not accessible to users
- Prevents crash by preventing access to broken functionality
Future work needed:
- Implement pure-Go internal player using FFmpeg libraries
- OR implement simple preview-only playback using existing preview system
- Must be self-contained and lightweight

Implemented two key optimizations to smooth queue list updates:
1. Increased auto-refresh interval from 1000ms to 2000ms
- Reduces frequency of view rebuilds
- Gives UI more time to stabilize between updates
2. Reduced scroll restoration delay from 50ms to 10ms
- Minimizes visible jump during position restoration
- Saves offset to variable before goroutine to avoid race conditions
These changes work together to provide a smoother queue viewing
experience by reducing rebuild frequency while accelerating scroll
position recovery.

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
- Created padded containers for both labels
- Updated settingsContent VBox to use containers instead of labels
- Consistent with fix from commit 1051329
Impact:
- Batch settings text now wraps properly

- Example: "CBR mode: Constant bitrate - predictable file quality. Use for strict size requirements or s"
- 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
- Labels now wrap at available width instead of extending beyond bounds
Affected Hint Labels:
- encoderPresetHint: Encoder preset descriptions
- encodingHint: Bitrate mode (CRF/CBR/VBR/Target Size) hints
- frameRateHint: Frame rate change warnings
- outputHint: Output file path display
- targetAspectHint: Aspect ratio selection hint
- hwAccelHint: Hardware acceleration guidance
Implementation:
- Created *Container versions of each hint label
- Wrapped label in container.NewPadded(label)
- Replaced direct label usage with container in VBox layouts

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
Files Changed:
- main.go: appState field, refreshQueueView(), stopQueueAutoRefresh()
- internal/ui/queueview.go: BuildQueueView(), buildJobItem()
Impact:
- Eliminates goroutine leak that caused resource exhaustion
- Clean shutdown of animation goroutines on refresh and navigation
- Should dramatically reduce memory usage and CPU overhead

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.
