Implements comprehensive frame navigation UI and keyboard shortcuts:
Frame Navigation UI:
- Frame step buttons (←/→ icons) for single-frame stepping
- Keyframe jump buttons (⏮/⏭ icons) for I-frame navigation
- Frame counter display showing current frame number
- All navigation controls only visible in keyframing mode
- Automatic keyframe index loading when enabling frame mode
Keyboard Shortcuts:
- Left/Right arrows: step one frame backward/forward
- Up/Down arrows: jump to previous/next keyframe
- Space: play/pause toggle
- All shortcuts only active in keyframing mode
Frame Counter:
- Displays current frame number during playback
- Updates in real-time as video plays
- Shows "(KF)" suffix when on a keyframe
- Positioned next to playlist toggle button
Technical Details:
- StepFrame() method pauses playback and seeks precisely
- GetCurrentPosition() added to playSession for position queries
- Keyframe navigation uses binary search from detector.go
- All UI updates properly synchronized via Fyne.Do()
- Frame counter declared early for use in updateProgress callback

Core implementation:
- Create internal/keyframe package with detector.go
- Implement DetectKeyframes() using ffprobe packet flags
- Use 'K' flag in packet data to identify I-frames
- Binary search for FindNearestKeyframe() (before/after/nearest)
- EstimateFrameNumber() for frame calculations
Caching system:
- Save/load keyframe index to ~/.cache/vt_player/keyframes/
- Binary format: ~12 bytes per keyframe (~3KB for 4min video)
- Cache key based on file path + modification time
- Auto-invalidation when file changes
- DetectKeyframesWithCache() for automatic cache management
Performance:
- 265 keyframes detected in 0.60s for 4min video (441 kf/sec)
- FindNearestKeyframe: 67ns per lookup (binary search)
- Memory: ~3KB cache per video
- Exceeds target: <5s for 1-hour video
Integration:

- Benchmark tests for search performance
- cmd/test_keyframes utility for validation
- Tested on real video files

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)

Add comprehensive Windows support roadmap:
- Cross-compilation and build system
- Platform-specific path handling
- Windows GPU detection (NVENC/QSV/AMF)
- Installer and distribution
- Testing checklist
Goal: Make VideoTools available for Jake and Windows users
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.
The new installation system provides a painless, one-command setup for all users:
install.sh Enhancements:
- 5-step installation wizard with visual progress indicators
- Auto-detects bash/zsh shell and updates rc files appropriately
- Automatically adds PATH exports for system-wide or user-local installation
- Automatically sources alias.sh for convenience commands
- Clear instructions for next steps
- Better error messages and validation
- Supports both sudo and non-sudo installation paths
- Default to user-local installation (no sudo required)
INSTALLATION.md Documentation:
- Comprehensive installation guide for all user types
- Multiple installation options (system-wide vs user-local)
- Detailed troubleshooting section
- Manual installation instructions for advanced users
- Platform-specific notes (Linux, macOS, Windows WSL)
- Uninstallation instructions
- Verification steps
README.md Updates:
- Updated Quick Start section to reference install.sh
- Added INSTALLATION.md to documentation index
- Clear distinction between user and developer setup
This enables users to set up VideoTools with:
bash install.sh
source ~/.bashrc
VideoTools
No manual shell configuration needed!
