Implements mutual exclusion between 'Convert Now' and queue processing:
Behavior:
- If queue is running: 'Convert Now' button is DISABLED
- If user tries to click 'Convert Now' while queue runs: Shows info dialog
with message and auto-adds video to queue instead
- Only one conversion method active at a time
This prevents:
- Multiple simultaneous FFmpeg processes competing for system resources
- Confusion about which conversion is running
- Queue and direct conversion interfering with each other
When queue is active:
- 'Convert Now' button: DISABLED (grey out)
- 'Add to Queue' button: ENABLED (highlighted)
- Clear UI signal: Only use queue mode for batch operations
Perfect for batch workflows where user loads multiple videos
and expects them all to process sequentially in the queue,
not spawn random direct conversions.
Implements automatic queue processing when jobs are added from the Convert
module via the 'Add to Queue' button:
Features:
- IsRunning() method added to queue package to check processing status
- 'Add to Queue' button now auto-starts queue if not already running
- Eliminates need to manually open Queue view and click 'Start Queue'
- Seamless workflow: Add video → Queue → Auto-starts conversion
Before:
1. Load video
2. Click 'Add to Queue'
3. Click 'View Queue'
4. Click 'Start Queue'
After:
1. Load video
2. Click 'Add to Queue' (auto-starts!)
3. Load next video
4. Click 'Add to Queue' (already running)
Perfect for batch operations where user loads multiple videos and expects
them to start encoding immediately.
Implements clear batch settings control for converting multiple videos:
Features:
- Settings persistence: All conversion settings automatically persist across videos
- Clear UI messaging: Explains that settings carry over between videos
- Reset button: One-click ability to reset all settings to defaults
- Batch workflow: Load video → set format/quality once → convert multiple videos
How it works:
1. User loads first video and configures settings (format, quality, codecs, etc)
2. Settings are stored in state.convert and persist across video loads
3. User can load additional videos - settings remain the same
4. When converting multiple videos, all use the same settings
5. User can change settings anytime - affects all subsequent videos
6. Reset button available to restore defaults if needed
This eliminates the need to reconfigure every video while allowing:
- Batch processing with same settings
- Individual video settings override when needed
- Clear visual indication of what's happening
Perfect for the user's workflow of converting 5 European videos to
DVD-NTSC format - set once, convert all 5!
Critical fix: When a DVD format (NTSC or PAL) is selected, now properly
override the video and audio codec to use DVD-compliant standards:
Video:
- Forces MPEG-2 codec (mpeg2video)
- NTSC: 6000k bitrate, 9000k max, gop=15
- PAL: 8000k bitrate, 9500k max, gop=12
Audio:
- Forces AC-3 codec for DVD container compatibility
- 192 kbps bitrate
- 48 kHz sample rate (DVD standard)
- Stereo channels (2)
This ensures that selecting a DVD format produces DVDStyler-compatible
MPEG files without codec errors. Previously, the code was using the
default H.264 + AAC, which caused 'unsupported audio codec' errors
when trying to write to MPEG container.
Fixes the issue where DVD conversions were failing with:
'Unsupported audio codec. Must be one of mp1, mp2, mp3, 16-bit pcm_dvd,
pcm_s16be, ac3 or dts.'
The setContent function was calling fyne.DoAndWait() from the main goroutine,
which created a deadlock. Changed to use fyne.Do() (asynchronous) to properly
marshal UI updates without blocking.
This resolves the error:
'fyne.Do[AndWait] called from main goroutine'
The async approach is correct here since we don't need to wait for the
content update to complete before continuing.
This commit includes several improvements:
Queue System Enhancements:
- Improved thread-safety in Add, Remove, Pause, Resume, Cancel operations
- Added PauseAll and ResumeAll methods for batch control
- Added MoveUp and MoveDown methods to reorder queue items
- Better handling of running job cancellation with proper state management
- Improved Copy strategy in List() to prevent race conditions
Convert Module Enhancement:
- Auto-set resolution to 720×480 when NTSC DVD format selected
- Auto-set resolution to 720×576 when PAL DVD format selected
- Auto-set framerate to 29.97fps (30) for NTSC, 25fps for PAL
- Added DVD resolution options to resolution selector dropdown
Display Server Improvements:
- Auto-detect Wayland vs X11 display servers in player controller
- Conditionally apply xdotool window placement (X11 only)
UI Improvements:
- Added Pause All, Resume All, and queue reordering buttons
- Fixed queue counter labeling (completed count display)
Added scripts folder with three convenience scripts:
• scripts/build.sh - Clean build with dependency verification
• scripts/run.sh - Run application (auto-builds if needed)
• scripts/alias.sh - Create 'VideoTools' command alias
Usage:
source scripts/alias.sh
VideoTools # Run app
VideoToolsRebuild # Force rebuild
VideoToolsClean # Clean artifacts
Fixed main.go DVD options:
• Fixed callback ordering so updateDVDOptions is called on format selection
• DVD aspect ratio selector now appears when DVD format is selected
• DVD info display shows specs for NTSC and PAL formats
• Works in both Simple and Advanced tabs
DVD options are now fully functional in the UI.
Integrated DVD-NTSC and DVD-PAL options into the Convert module's Simple and Advanced modes.
New Features:
✓ DVD-NTSC (720×480 @ 29.97fps) option in format selector
✓ DVD-PAL (720×576 @ 25.00fps) option in format selector
✓ DVD aspect ratio selector (4:3 or 16:9)
✓ Dynamic DVD options panel - appears only when DVD format selected
✓ Informative DVD specs displayed based on format selection
✓ Smart show/hide logic for DVD-specific controls
✓ Works in both Simple and Advanced mode tabs
DVD Specifications Displayed:
- NTSC: 720×480 @ 29.97fps, MPEG-2, AC-3 Stereo 48kHz
- PAL: 720×576 @ 25.00fps, MPEG-2, AC-3 Stereo 48kHz
- Bitrate ranges and compatibility info
Users can now:
1. Select DVD format from dropdown
2. Choose aspect ratio (4:3 or 16:9)
3. See relevant DVD specs and compatibility
4. Queue DVD conversion jobs
5. Process with existing queue system

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
