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

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

- 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

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()

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.

Priority 5: Adaptive Frame Timing
- Implemented drift correction for smooth video playback
- Frame dropping when >3 frames behind schedule
- Gradual catchup when moderately behind
- Maintains smooth playback under system load
Frame Timing Logic:
- 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)

Resolved issue where window would resize itself based on dynamic content
like progress bars and queue updates. Window now maintains the size that
the user sets, regardless of content changes.
**Problem:**
- When progress bars updated or queue content changed, the window would
automatically resize to fit the new content MinSize
- This caused the window to get larger or smaller unexpectedly
- User-set window size was not being preserved
**Solution:**
- Modified setContent() to capture current window size before setting new content
- Restore the window size after SetContent() completes
- This prevents Fyne from auto-resizing based on content MinSize changes
- Window only resizes when user manually drags edges or maximizes
**Impact:**
- Window maintains stable size through all content changes
- Progress bars, queue updates, and module switches no longer trigger resize
- User retains full control of window size via manual resize/maximize
- Improves professional appearance and user experience

Added advanced audio channel remixing features for videos with imbalanced
left/right audio channels (e.g., music in left ear, vocals in right ear).
New audio channel options using FFmpeg pan filter:
- Left to Stereo: Copy left channel to both speakers
- Right to Stereo: Copy right channel to both speakers
- Mix to Stereo: Downmix both channels together evenly
- Swap L/R: Swap left and right channels
Changes:
- Updated audioChannelsSelect dropdown with 8 options (was 4)
- Implemented pan filter logic in all 4 FFmpeg command builders:
- buildFFmpegCommandFromJob (main convert)
- DVD encoding function
- Convert command builder
- Snippet generation
- Removed unused "os" import from internal/convert/ffmpeg.go
- Updated DONE.md with audio channel remixing feature
The pan filter syntax allows precise channel routing:
- pan=stereo|c0=c0|c1=c0 (left to both)
- pan=stereo|c0=c1|c1=c1 (right to both)
- pan=stereo|c0=0.5*c0+0.5*c1|c1=0.5*c0+0.5*c1 (mix)
- pan=stereo|c0=c1|c1=c0 (swap)

In Progress Tab Enhancements:
- Added animated striped progress bars to in-progress jobs
- Exported ModuleColor function for reuse across modules
- Shows real-time progress (0-100%) with module-specific colors
- Progress updates automatically as jobs run
- Maintains consistent visual style with queue view
Lossless Quality Preset Improvements:
- H.265 and AV1 now support all bitrate modes with lossless quality
- Lossless with Target Size mode now works for H.265/AV1
- H.264 and MPEG-2 no longer show "Lossless" option (codec limitation)
- Dynamic quality dropdown updates based on selected codec
- Automatic fallback to "Near-Lossless" when switching from lossless-capable
codec to non-lossless codec
Quality Options Logic:
- Base options: Draft, Standard, Balanced, High, Near-Lossless
- "Lossless" only appears for H.265 and AV1
- codecSupportsLossless() helper function checks compatibility
- updateQualityOptions() refreshes dropdown when codec changes
Lossless + Bitrate Mode Combinations:
- Lossless + CRF: Forces CRF 0 for perfect quality
- Lossless + CBR: Constant bitrate with lossless quality
- Lossless + VBR: Variable bitrate with lossless quality
- Lossless + Target Size: Calculates bitrate for exact file size with
best possible quality (now allowed for H.265/AV1)
Technical Implementation:
- Added Progress field to ui.HistoryEntry struct
- Exported StripedProgress widget and ModuleColor function
- updateQualityOptions() function dynamically filters quality presets
- updateEncodingControls() handles lossless modes per codec
- Descriptive hints explain each lossless+bitrate combination
This allows professional workflows where lossless quality is desired
but file size constraints still need to be met using Target Size mode.

Restructured bitrate controls to hide unused options based on mode,
and improved VBR encoding to use 2-pass for accurate bitrate targeting.
UI Improvements:
- Wrapped CRF, bitrate, and target size controls in hideable containers
- Only show relevant controls based on selected bitrate mode:
* CRF mode: Show only CRF entry
* CBR mode: Show only bitrate entry and presets
* VBR mode: Show only bitrate entry and presets
* Target Size mode: Show only target size controls
- Added descriptive hints for each mode explaining behavior
- Updated DVD mode to work with new container structure
- Made command preview update when bitrate settings change
Encoding Improvements:
- VBR now uses maxrate at 1.5x target for quality peaks
- VBR automatically enables 2-pass encoding for accuracy
- CBR remains strict (minrate=maxrate=target) for guaranteed bitrate
- Target Size mode continues to calculate exact bitrate from duration
This addresses runaway bitrate issues by:
1. Making it clear which mode is active
2. Hiding confusing unused controls
3. Ensuring VBR hits target average bitrate with 2-pass
4. Keeping CBR strict for exact constant bitrate
Pros of manual bitrate targeting:
- Predictable file sizes
- Meets strict size requirements
- Good for streaming with bandwidth constraints
Cons of manual bitrate targeting:
- Variable quality (simple scenes waste bits, complex scenes starve)
- Less efficient than CRF overall
- Requires 2-pass for VBR accuracy (slower)
