Latest Updates - November 29, 2025

Summary

This session focused on three major improvements to VideoTools:

1. Auto-Resolution for DVD Formats - Automatically sets correct resolution when selecting NTSC/PAL
2. Queue System Improvements - Better thread-safety and new control features
3. Professional Installation System - One-command setup for users

---

1. Auto-Resolution for DVD Formats

What Changed

When you select a DVD format in the Convert module, the resolution and framerate now automatically set to match the standard:

• Select "DVD-NTSC (MPEG-2)" → automatically sets resolution to 720×480 and framerate to 30fps
• Select "DVD-PAL (MPEG-2)" → automatically sets resolution to 720×576 and framerate to 25fps

Why It Matters

• No More Manual Setting - Users don't need to understand DVD resolution specs
• Fewer Mistakes - Prevents encoding to wrong resolution
• Faster Workflow - One click instead of three
• Professional Output - Ensures standards compliance

How to Use

1. Go to Convert module
2. Load a video
3. Select a DVD format → resolution/framerate auto-set!
4. In Advanced Mode, you'll see the options pre-filled correctly

Technical Details

File: main.go lines 1416-1643

• Added DVD resolution options to resolution selector dropdown
• Implemented updateDVDOptions() function to handle auto-setting
• Updates both UI state and convert configuration

2. Queue System Improvements

New Methods

The queue system now includes several reliability and control improvements:

• PauseAll() - Pause any running job and stop processing
• ResumeAll() - Restart queue processing from paused state
• MoveUp(id) / MoveDown(id) - Reorder pending/paused jobs in the queue
• Better thread-safety - Improved locking in Add, Remove, Pause, Resume, Cancel operations

UI Improvements

The queue view now displays:

• Pause All button - Quickly pause everything
• Resume All button - Restart processing
• Up/Down arrows on each job - Reorder items manually
• Better status tracking - Improved running/paused/completed indicators

Why It Matters

• More Control - Users can pause/resume/reorder jobs
• Better Reliability - Improved thread-safety prevents race conditions
• Batch Operations - Control all jobs with single buttons
• Flexibility - Reorder jobs without removing them

File Changes

File: internal/queue/queue.go

• Fixed mutex locking in critical sections
• Added PauseAll() and ResumeAll() methods
• Added MoveUp/MoveDown methods for reordering
• Improved Copy strategy in List() method
• Better handling of running job cancellation

File: internal/ui/queueview.go

• Added new control buttons (Pause All, Resume All, Start Queue)
• Added reordering UI (up/down arrows)
• Improved job display and status tracking

3. Professional Installation System

New Files

1. Enhanced install.sh - One-command installation
2. New INSTALLATION.md - Comprehensive installation guide

install.sh Features

The installer now performs all setup automatically:

bash install.sh

This handles:

1. ✅ Go installation verification
2. ✅ Building VideoTools from source
3. ✅ Choosing installation path (system-wide or user-local)
4. ✅ Installing binary to proper location
5. ✅ Auto-detecting shell (bash/zsh)
6. ✅ Updating PATH in shell rc file
7. ✅ Sourcing alias.sh for convenience commands
8. ✅ Providing next-steps instructions

Installation Options

Option 1: System-Wide (for shared computers)

bash install.sh
# Select option 1 when prompted

Option 2: User-Local (default, no sudo required)

bash install.sh
# Select option 2 when prompted (or just press Enter)

After Installation

source ~/.bashrc    # Load the new aliases
VideoTools          # Run the application

Available Commands

After installation:

• VideoTools - Run the application
• VideoToolsRebuild - Force rebuild from source
• VideoToolsClean - Clean build artifacts

Why It Matters

• Zero Setup - No manual shell configuration needed
• User-Friendly - Guided choices with sensible defaults
• Automatic Environment - PATH and aliases configured automatically
• Professional Experience - Matches expectations of modern software

Documentation

INSTALLATION.md includes:

• Quick start instructions
• Multiple installation options
• Troubleshooting section
• Manual installation instructions
• Platform-specific notes
• Uninstallation instructions
• Verification steps

Display Server Auto-Detection

What Changed

The player controller now auto-detects the display server:

File: internal/player/controller_linux.go

• Checks for Wayland environment variable
• Uses Wayland if available, falls back to X11
• Conditional xdotool window placement (X11 only)

Why It Matters

• Works with Wayland - Modern display server support
• Backwards Compatible - Still works with X11
• No Configuration - Auto-detects automatically

2. Go to Convert module
3. Select "DVD-NTSC (MPEG-2)" or "DVD-PAL (MPEG-2)"
4. Check that resolution auto-sets (Advanced Mode)

For Testing Queue Improvements

1. Add multiple jobs to queue
2. Test Pause All / Resume All buttons
3. Test reordering with up/down arrows

For Testing Installation

1. Run bash install.sh on a clean system
2. Verify binary is in PATH
3. Verify aliases are available

---

Next Steps

For Your Testing

1. Test the new auto-resolution feature with NTSC and PAL formats
2. Test queue improvements (Pause All, Resume All, reordering)
3. Test the installation system on a fresh checkout

For Future Development

1. Implement FFmpeg execution integration (call BuildDVDFFmpegArgs)
2. Display validation warnings in UI before queuing
3. Test with DVDStyler for compatibility verification
