Implements video transformation features:
- Horizontal flip (mirror effect) using hflip filter
- Vertical flip (upside down) using vflip filter
- Rotation support: 90°, 180°, 270° clockwise using transpose filters
UI additions in Advanced mode:
- New "VIDEO TRANSFORMATIONS" section
- Two checkboxes for flip controls with descriptive labels
- Dropdown selector for rotation angles
- Hint text explaining transformation purpose
Filter implementation:
- Applied after aspect ratio conversion, before frame rate conversion
- Works in both queue-based and direct conversion paths
- Uses FFmpeg standard filters: hflip, vflip, transpose
Addresses user request to add flip/rotation capabilities inspired by Jake's script using -vf hflip.

This commit includes three critical bug fixes and Windows build improvements:
**Bug Fixes:**
1. **Queue Conversion Progress Tracking** (main.go:1471-1534)
- Enhanced executeConvertJob() to parse FPS, speed, and ETA from FFmpeg output
- Queue jobs now show detailed progress metrics matching direct conversions
- Stats stored in job.Config for display in the conversion stats bar
2. **AMD AMF Hardware Acceleration** (main.go)
- Added "amf" to hardware acceleration options
- Support for h264_amf, hevc_amf, and av1_amf encoders
- Added AMF-specific error detection in FFmpeg output parsing
3. **DVD Format Resolution Forcing** (main.go:1080-1103, 4504-4517)
- Removed automatic resolution forcing when DVD format is selected
- Removed -target parameter usage which was forcing 720×480/720×576
- Resolution now defaults to "Source" unless explicitly changed
- DVD compliance maintained through manual bitrate/GOP/codec parameters
**Windows Build Improvements:**
- Updated build.bat to enable CGO (required for Fyne/OpenGL)
- Added automatic GCC/MinGW-w64 detection and installation
- Automated setup via winget for one-command Windows builds
- Improved error messages with fallback manual instructions
**Documentation:**
- Added comprehensive Windows setup guides
- Created platform.go for future platform-specific code
- Updated .gitignore for Windows build artifacts
All changes tested and working. Ready for production use.

Features:
- FPS counter in conversion status showing real-time encoding speed
- Job queue now displays FPS, encoding speed (e.g., "1.2x"), and ETA for running conversions
- Copy Comparison button exports side-by-side metadata comparison report
- Auto-compare checkbox in Convert module - automatically loads Compare view after conversion
- Convert Now properly adds job to queue and displays in Job Queue with live stats
- Module badge colors in job queue now match main menu tile colors
- Fixed fullscreen compare window sizing (reduced player dimensions to prevent overflow)
Bug Fixes:
- Fixed queue state management - only one job runs at a time (prevents multiple jobs showing "running")
- Fixed Compare module slot assignment - single video drops now fill empty slot instead of overwriting
- Fixed job queue scroll rubber banding (no longer jumps back to top)
- Enhanced crop detection validation for WMV/AVI formats with dimension clamping and bounds checking
Documentation:
- VT_Player integration notes with API requirements for keyframing and trim features
- LosslessCut feature analysis for Trim module inspiration
- Video metadata guide covering MP4/MKV custom fields and NFO generation
- Trim module design specification
- Compare fullscreen mode documentation
- Updated VIDEO_PLAYER_FORK.md to mark fork as completed
Technical Changes:
- Added state tracking for FPS, speed, and ETA (main.go:197-199)
- Enhanced queue processJobs() to check for running jobs before starting new ones
- Improved Compare module drag-and-drop logic with smart slot assignment (both code paths)
- Added deferred scroll position restoration to prevent UI jumping
- Job queue Config map now carries conversion stats for display

Fixed thumbnails not displaying:
- Added preview frame generation to Compare module
- Thumbnails now load asynchronously when videos are loaded
- Uses capturePreviewFrames() just like Convert module
- Thumbnails appear after brief generation delay
Added Clear All button:
- Positioned to the right of instructions text
- Clears both File 1 and File 2 slots
- Refreshes view to show empty state
- Low importance styling (not highlighted)
Layout improvements:
- Instructions row now uses Border layout
- Clear All button aligned to the right
- Clean, accessible button placement
Both videos now show thumbnails (240x135) automatically
when loaded, providing visual confirmation of loaded content.
Fixed issue where dragging single videos would overwrite existing data:
Smart slot filling logic:
- Single video dropped: Fills first empty slot (File 1 then File 2)
- If both slots full: Shows dialog asking user to Clear first
- Multiple videos dropped: Fills both slots (replaces existing)
Behavior changes:
1. Drag first video → goes to slot 1
2. Drag second video → goes to slot 2
3. Drag third video → shows "Both Slots Full" message
4. Drag 2+ videos together → replaces both slots
User experience improvements:
- No more accidental overwrites when loading one at a time
- Clear feedback when slots are full
- Can now build comparison by dragging videos individually
- Or drag both at once to start fresh
Main menu drag-and-drop to Compare tile:
- Already working correctly
- Loads both videos sequentially then shows module
- No changes needed to that path
This makes the Compare workflow much more intuitive and prevents
losing loaded video data when adding the second video.
Fixed critical bug where loading second video would overwrite first:
- Changed parallel goroutines to sequential loading
- Load file 1, then file 2, then refresh UI once
- Prevents race condition from multiple showCompareView() calls
- Both files now display correctly side by side
Added action buttons for each file:
- Copy Metadata button: Copies formatted metadata to clipboard
- Clear button: Removes video from slot and refreshes display
- Buttons arranged horizontally: Load | Copy | Clear
- Low importance styling for secondary actions
Changes to drag-and-drop handlers:
- Within Compare module: sequential loading, single refresh
- From main menu: already sequential, no changes needed
- Both paths now work correctly
This fixes the "second file overwrites first" issue and adds
the requested metadata copy and clear functionality.
Fixed window resizing issues for better cross-platform behavior:
Convert module video pane:
- Reduced video pane minimum from 460x260 to 320x180
- Removed rigid MinSize on outer container (commented out)
- Removed rigid MinSize on image element
- Set stage minimum to 200x113 (reasonable 16:9 minimum)
- Video pane now scales down allowing smaller windows
Compare module:
- Reduced thumbnail minimum from 320x180 to 240x135
- Reduced metadata scroll minimum from 300x200 to 250x150
- More compact layout allows better window resizing
Benefits:
- Window can now shrink to fit smaller screens
- Better behavior on tiling window managers
- More flexible for cross-platform (Windows, macOS, Linux)
- Content scales intelligently instead of forcing window size
Note: Double-click titlebar maximize is a Fyne framework limitation.
Maximize via window controls or OS shortcuts (F11, Super+Up) works.
Added window centering to improve initial presentation:
- Call w.CenterOnScreen() after setting window size
- Window now opens centered rather than at OS default position
- Maintains existing resizing and maximization support
The window is already maximizable via SetFixedSize(false).
Users can maximize using OS window controls (double-click
titlebar, maximize button, or OS shortcuts like F11/Super+Up).
Prevents long filenames from manipulating window size:
- Truncate filenames longer than 35 characters
- Smart truncation preserves file extension
- Format: "long-filename-na...mp4" instead of wrapping
- Falls back to simple truncation for very long extensions
- Removed text wrapping from labels (no longer needed)
Examples:
- "my-very-long-video-filename.mp4" → "my-very-long-video-fi....mp4"
- "short.mp4" → "short.mp4" (unchanged)
- "filename.mkv" → kept as-is if under 35 chars
This ensures the Compare module labels stay compact and
predictable regardless of filename length.
