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.
This commit implements two new features:
1. Compare Module:
- New UI module for side-by-side video comparison
- Loads two video files and displays detailed metadata comparison
- Shows format, resolution, codecs, bitrates, frame rate, color info, etc.
- Accessible via GUI module button or CLI: videotools compare <file1> <file2>
- Added formatBitrate() helper function for consistent bitrate display
2. Target File Size Encoding Mode:
- New bitrate mode "Target Size" for convert module
- Allows users to specify desired output file size (e.g., "25MB", "100MB", "8MB")
- Automatically calculates required video bitrate based on:
* Target file size
* Video duration
* Audio bitrate
* Container overhead (3% reserved)
- Implemented ParseFileSize() to parse size strings (KB, MB, GB)
- Implemented CalculateBitrateForTargetSize() for bitrate calculation
- Works in both GUI convert view and job queue execution
Additional changes:
- Updated printUsage() to include compare command
- Added compare button to module grid with pink color
- Added compareFile1 and compareFile2 to appState
- Consistent "Target Size" naming throughout (UI and code)
