Subject: [PATCH] Add dev14 fixes: progress tracking, AMD AMF support, DVD
 resolution fix, and Windows build automation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

+# Building VideoTools
+
+VideoTools uses a universal build script that automatically detects your platform and builds accordingly.
+
+---
+
+## Quick Start (All Platforms)
+
+```bash
+./scripts/build.sh
+```
+
+That's it! The script will:
+- ✅ Detect your platform (Linux/macOS/Windows)
+- ✅ Build the appropriate executable
+- ✅ On Windows: Offer to download FFmpeg automatically
+
+---
+
+## Platform-Specific Details
+
+### Linux
+
+**Prerequisites:**
+- Go 1.21+
+- FFmpeg (system package)
+- CGO build dependencies
+
+**Install FFmpeg:**
+```bash
+# Fedora/RHEL
+sudo dnf install ffmpeg
+
+# Ubuntu/Debian
+sudo apt install ffmpeg
+
+# Arch Linux
+sudo pacman -S ffmpeg
+```
+
+**Build:**
+```bash
+./scripts/build.sh
+```
+
+**Output:** `VideoTools` (native executable)
+
+**Run:**
+```bash
+./VideoTools
+```
+
+---
+
+### macOS
+
+**Prerequisites:**
+- Go 1.21+
+- FFmpeg (via Homebrew)
+- Xcode Command Line Tools
+
+**Install FFmpeg:**
+```bash
+brew install ffmpeg
+```
+
+**Build:**
+```bash
+./scripts/build.sh
+```
+
+**Output:** `VideoTools` (native executable)
+
+**Run:**
+```bash
+./VideoTools
+```
+
+---
+
+### Windows
+
+**Prerequisites:**
+- Go 1.21+
+- MinGW-w64 (for CGO)
+- Git Bash or similar (to run shell scripts)
+
+**Build:**
+```bash
+./scripts/build.sh
+```
+
+The script will:
+1. Build `VideoTools.exe`
+2. Prompt to download FFmpeg automatically
+3. Set up everything in `dist/windows/`
+
+**Output:** `VideoTools.exe` (Windows GUI executable)
+
+**Run:**
+- Double-click `VideoTools.exe` in `dist/windows/`
+- Or: `./VideoTools.exe` from Git Bash
+
+**Automatic FFmpeg Setup:**
+```bash
+# The build script will offer this automatically, or run manually:
+./setup-windows.bat
+
+# Or in PowerShell:
+.\scripts\setup-windows.ps1 -Portable
+```
+
+---
+
+## Advanced: Manual Platform-Specific Builds
+
+### Linux/macOS Native Build
+```bash
+./scripts/build-linux.sh
+```
+
+### Windows Cross-Compile (from Linux)
+```bash
+# Install MinGW first
+sudo dnf install mingw64-gcc mingw64-winpthreads-static  # Fedora
+# OR
+sudo apt install gcc-mingw-w64  # Ubuntu/Debian
+
+# Cross-compile
+./scripts/build-windows.sh
+
+# Output: dist/windows/VideoTools.exe (with FFmpeg bundled)
+```
+
+---
+
+## Build Options
+
+### Clean Build
+```bash
+# The build script automatically cleans cache
+./scripts/build.sh
+```
+
+### Debug Build
+```bash
+# Standard build includes debug info by default
+CGO_ENABLED=1 go build -o VideoTools
+
+# Run with debug logging
+./VideoTools -debug
+```
+
+### Release Build (Smaller Binary)
+```bash
+# Strip debug symbols
+go build -ldflags="-s -w" -o VideoTools
+```
+
+---
+
+## Troubleshooting
+
+### "go: command not found"
+Install Go 1.21+ from https://go.dev/dl/
+
+### "CGO_ENABLED must be set"
+CGO is required for Fyne (GUI framework):
+```bash
+export CGO_ENABLED=1
+./scripts/build.sh
+```
+
+### "ffmpeg not found" (Linux/macOS)
+Install FFmpeg using your package manager (see above).
+
+### Windows: "x86_64-w64-mingw32-gcc not found"
+Install MinGW-w64:
+- MSYS2: https://www.msys2.org/
+- Or standalone: https://www.mingw-w64.org/
+
+### macOS: "ld: library not found"
+Install Xcode Command Line Tools:
+```bash
+xcode-select --install
+```
+
+---
+
+## Build Artifacts
+
+After building, you'll find:
+
+### Linux/macOS:
+```
+VideoTools/
+└── VideoTools          # Native executable
+```
+
+### Windows:
+```
+VideoTools/
+├── VideoTools.exe      # Main executable
+└── dist/
+    └── windows/
+        ├── VideoTools.exe
+        ├── ffmpeg.exe      # (after setup)
+        └── ffprobe.exe     # (after setup)
+```
+
+---
+
+## Development Builds
+
+For faster iteration during development:
+
+```bash
+# Quick build (no cleaning)
+go build -o VideoTools
+
+# Run directly
+./VideoTools
+
+# With debug output
+./VideoTools -debug
+```
+
+---
+
+## CI/CD
+
+The build scripts are designed to work in CI/CD environments:
+
+```yaml
+# Example GitHub Actions
+- name: Build VideoTools
+  run: ./scripts/build.sh
+```
+

+# VideoTools - Windows Setup Guide
+
+This guide will help you get VideoTools running on Windows 10/11.
+
+---
+
+## Prerequisites
+
+VideoTools requires **FFmpeg** to function. You have two options:
+
+### Option 1: Install FFmpeg System-Wide (Recommended)
+
+1. **Download FFmpeg**:
+   - Go to: https://github.com/BtbN/FFmpeg-Builds/releases
+   - Download: `ffmpeg-master-latest-win64-gpl.zip`
+
+2. **Extract and Install**:
+   ```cmd
+   # Extract to a permanent location, for example:
+   C:\Program Files\ffmpeg\
+   ```
+
+3. **Add to PATH**:
+   - Open "Environment Variables" (Windows Key + type "environment")
+   - Edit "Path" under System Variables
+   - Add: `C:\Program Files\ffmpeg\bin`
+   - Click OK
+
+4. **Verify Installation**:
+   ```cmd
+   ffmpeg -version
+   ```
+   You should see FFmpeg version information.
+
+### Option 2: Bundle FFmpeg with VideoTools (Portable)
+
+1. **Download FFmpeg**:
+   - Same as above: https://github.com/BtbN/FFmpeg-Builds/releases
+   - Download: `ffmpeg-master-latest-win64-gpl.zip`
+
+2. **Extract ffmpeg.exe**:
+   - Open the zip file
+   - Navigate to `bin/` folder
+   - Extract `ffmpeg.exe` and `ffprobe.exe`
+
+3. **Place Next to VideoTools**:
+   ```
+   VideoTools\
+   ├── VideoTools.exe
+   ├── ffmpeg.exe       ← Place here
+   └── ffprobe.exe      ← Place here
+   ```
+
+This makes VideoTools portable - you can run it from a USB stick!
+
+---
+
+## Running VideoTools
+
+### First Launch
+
+1. Double-click `VideoTools.exe`
+2. If you see a Windows SmartScreen warning:
+   - Click "More info"
+   - Click "Run anyway"
+   - (This happens because the app isn't code-signed yet)
+
+3. The main window should appear
+
+### Troubleshooting
+
+**"FFmpeg not found" error:**
+- VideoTools looks for FFmpeg in this order:
+  1. Same folder as VideoTools.exe
+  2. FFMPEG_PATH environment variable
+  3. System PATH
+  4. Common install locations (Program Files)
+
+**Error opening video files:**
+- Make sure FFmpeg is properly installed (run `ffmpeg -version` in cmd)
+- Check that video file path doesn't have special characters
+- Try copying the video to a simple path like `C:\Videos\test.mp4`
+
+**Application won't start:**
+- Make sure you have Windows 10 or later
+- Check that you downloaded the 64-bit version
+- Verify your graphics drivers are up to date
+
+**Black screen or rendering issues:**
+- Update your GPU drivers (NVIDIA, AMD, or Intel)
+- Try running in compatibility mode (right-click → Properties → Compatibility)
+
+---
+
+## Hardware Acceleration
+
+VideoTools automatically detects and uses hardware acceleration when available:
+
+- **NVIDIA GPUs**: Uses NVENC encoder (much faster)
+- **Intel GPUs**: Uses Quick Sync Video (QSV)
+- **AMD GPUs**: Uses AMF encoder
+
+Check the debug output to see what was detected:
+```cmd
+VideoTools.exe -debug
+```
+
+Look for lines like:
+```
+[SYS] Detected NVENC (NVIDIA) encoder
+[SYS] Hardware encoders: [nvenc]
+```
+
+---
+
+## Building from Source (Advanced)
+
+If you want to build VideoTools yourself on Windows:
+
+### Prerequisites
+- Go 1.21 or later
+- MinGW-w64 (for CGO)
+- Git
+
+### Steps
+
+1. **Install Go**:
+   - Download from: https://go.dev/dl/
+   - Install and verify: `go version`
+
+2. **Install MinGW-w64**:
+   - Download from: https://www.mingw-w64.org/
+   - Or use MSYS2: https://www.msys2.org/
+   - Add to PATH
+
+3. **Clone Repository**:
+   ```cmd
+   git clone https://github.com/yourusername/VideoTools.git
+   cd VideoTools
+   ```
+
+4. **Build**:
+   ```cmd
+   set CGO_ENABLED=1
+   go build -ldflags="-H windowsgui" -o VideoTools.exe
+   ```
+
+5. **Run**:
+   ```cmd
+   VideoTools.exe
+   ```
+
+---
+
+## Cross-Compiling from Linux
+
+If you're building for Windows from Linux:
+
+1. **Install MinGW**:
+   ```bash
+   # Fedora/RHEL
+   sudo dnf install mingw64-gcc mingw64-winpthreads-static
+
+   # Ubuntu/Debian
+   sudo apt-get install gcc-mingw-w64
+   ```
+
+2. **Build**:
+   ```bash
+   ./scripts/build-windows.sh
+   ```
+
+3. **Output**:
+   - Executable: `dist/windows/VideoTools.exe`
+   - Bundle FFmpeg as described above
+
+---
+
+## Known Issues on Windows
+
+1. **Console Window**: The app uses `-H windowsgui` flag to hide the console, but some configurations may still show it briefly
+
+2. **File Paths**: Avoid very long paths (>260 characters) on older Windows versions
+
+3. **Antivirus**: Some antivirus software may flag the executable. This is a false positive - the app is safe
+
+4. **Network Drives**: UNC paths (`\\server\share\`) should work but may be slower
+
+---
+
+## Getting Help
+
+If you encounter issues:
+
+1. Enable debug mode: `VideoTools.exe -debug`
+2. Check the error messages
+3. Report issues at: https://github.com/yourusername/VideoTools/issues
+
+Include:
+- Windows version (10/11)
+- GPU type (NVIDIA/AMD/Intel)
+- FFmpeg version (`ffmpeg -version`)
+- Full error message
+- Debug log output
+
+---
+
+## Performance Tips
+
+1. **Use Hardware Acceleration**: Make sure your GPU drivers are updated
+2. **SSD Storage**: Work with files on SSD for better performance
+3. **Close Other Apps**: Free up RAM and GPU resources
+4. **Preset Selection**: Use faster presets for quicker encoding

+# dev14: Windows Compatibility Implementation
+
+**Status**: ✅ Core implementation complete
+**Date**: 2025-12-04
+**Target**: Windows 10/11 support with cross-platform FFmpeg detection
+
+---
+
+## Overview
+
+This document summarizes the Windows compatibility implementation for VideoTools v0.1.0-dev14. The goal was to make VideoTools fully functional on Windows while maintaining Linux/macOS compatibility.
+
+---
+
+## Implementation Summary
+
+### 1. Platform Detection System (`platform.go`)
+
+Created a comprehensive platform detection and configuration system:
+
+**File**: `platform.go` (329 lines)
+
+**Key Components**:
+
+- **PlatformConfig struct**: Holds platform-specific settings
+  - FFmpeg/FFprobe paths
+  - Temp directory location
+  - Hardware encoder list
+  - OS detection flags (IsWindows, IsLinux, IsDarwin)
+
+- **DetectPlatform()**: Main initialization function
+  - Detects OS and architecture
+  - Locates FFmpeg/FFprobe executables
+  - Determines temp directory
+  - Detects available hardware encoders
+
+- **FFmpeg Discovery** (Priority order):
+  1. Bundled with application (same directory as executable)
+  2. FFMPEG_PATH environment variable
+  3. System PATH
+  4. Common install locations (Windows: Program Files, C:\ffmpeg\bin)
+
+- **Hardware Encoder Detection**:
+  - **Windows**: NVENC (NVIDIA), QSV (Intel), AMF (AMD)
+  - **Linux**: VAAPI, NVENC, QSV
+  - **macOS**: VideoToolbox, NVENC
+
+- **Platform-Specific Functions**:
+  - `ValidateWindowsPath()`: Validates drive letters and UNC paths
+  - `KillProcess()`: Platform-appropriate process termination
+  - `GetEncoderName()`: Maps hardware acceleration to encoder names
+
+### 2. FFmpeg Command Updates
+
+**Updated Files**:
+- `main.go`: 10 locations updated
+- `internal/convert/ffmpeg.go`: 1 location updated
+
+**Changes**:
+- All `exec.Command("ffmpeg", ...)` → `exec.Command(platformConfig.FFmpegPath, ...)`
+- All `exec.CommandContext(ctx, "ffmpeg", ...)` → `exec.CommandContext(ctx, platformConfig.FFmpegPath, ...)`
+
+**Package Variable Approach**:
+- Added `FFmpegPath` and `FFprobePath` variables to `internal/convert` package
+- These are set from `main()` during initialization
+- Allows internal packages to use correct platform paths
+
+### 3. Cross-Compilation Build Script
+

+
+## Code Changes Detail
+
+### main.go
+
+**Lines 74-76**: Added platformConfig global variable
+```go
+// Platform-specific configuration
+var platformConfig *PlatformConfig
+```
+
+**Lines 1537-1545**: Platform initialization
+```go
+// Detect platform and configure paths
+platformConfig = DetectPlatform()
+if platformConfig.FFmpegPath == "ffmpeg" || platformConfig.FFmpegPath == "ffmpeg.exe" {
+    logging.Debug(logging.CatSystem, "WARNING: FFmpeg not found in expected locations, assuming it's in PATH")
+}
+
+// Set paths in convert package
+convert.FFmpegPath = platformConfig.FFmpegPath
+convert.FFprobePath = platformConfig.FFprobePath
+```
+
+**Updated Functions** (10 locations):
+- Line 1426: `queueConvert()` - queue processing
+- Line 3411: `runVideo()` - video playback
+- Line 3489: `runAudio()` - audio playback
+- Lines 4233, 4245: `detectBestH264Encoder()` - encoder detection
+- Lines 4261, 4271: `detectBestH265Encoder()` - encoder detection
+- Line 4708: `startConvert()` - direct conversion
+- Line 5185: `generateSnippet()` - snippet generation
+- Line 5225: `capturePreviewFrames()` - preview capture
+- Line 5439: `probeVideo()` - cover art extraction
+- Line 5487: `detectCrop()` - cropdetect filter
+
+### internal/convert/ffmpeg.go
+
+**Lines 17-23**: Added package variables
+```go
+// FFmpegPath holds the path to the ffmpeg executable
+// This should be set by the main package during initialization
+var FFmpegPath = "ffmpeg"
+
+// FFprobePath holds the path to the ffprobe executable
+// This should be set by the main package during initialization
+var FFprobePath = "ffprobe"
+```
+
+**Line 248**: Updated cover art extraction
+
+---
+
+## Platform-Specific Behavior
+
+### Windows
+- Executable extension: `.exe`
+- Temp directory: `%LOCALAPPDATA%\Temp\VideoTools`
+- Path separator: `\`
+- Process termination: Direct `Kill()` (no SIGTERM)
+- Hardware encoders: NVENC, QSV, AMF
+- FFmpeg detection: Checks bundled location first
+
+### Linux
+- Executable extension: None
+- Temp directory: `/tmp/videotools`
+- Path separator: `/`
+- Process termination: Graceful `SIGTERM` → `Kill()`
+- Hardware encoders: VAAPI, NVENC, QSV
+- FFmpeg detection: Checks PATH
+
+### macOS
+- Executable extension: None
+- Temp directory: `/tmp/videotools`
+- Path separator: `/`
+- Process termination: Graceful `SIGTERM` → `Kill()`
+- Hardware encoders: VideoToolbox, NVENC
+- FFmpeg detection: Checks PATH
+
+---
+

+# Windows Compatibility Implementation Plan
+
+## Current Status
+
+VideoTools is built with Go + Fyne, which are inherently cross-platform. However, several areas need attention for full Windows support.
+
+---
+
+## ✅ Already Cross-Platform
+
+The codebase already uses good practices:
+- `filepath.Join()` for path construction
+- `os.TempDir()` for temporary files
+- `filepath.Separator` awareness
+- Fyne GUI framework (cross-platform)
+
+---
+
+## 🔧 Required Changes
+
+### 1. FFmpeg Detection and Bundling
+
+**Current**: Assumes `ffmpeg` is in PATH
+**Windows Issue**: FFmpeg not typically installed system-wide
+
+**Solution**:
+```go
+func findFFmpeg() string {
+    // Priority order:
+    // 1. Bundled ffmpeg.exe in application directory
+    // 2. FFMPEG_PATH environment variable
+    // 3. System PATH
+    // 4. Common install locations (C:\Program Files\ffmpeg\bin\)
+
+    if runtime.GOOS == "windows" {
+        // Check application directory first
+        exePath, _ := os.Executable()
+        bundledFFmpeg := filepath.Join(filepath.Dir(exePath), "ffmpeg.exe")
+        if _, err := os.Stat(bundledFFmpeg); err == nil {
+            return bundledFFmpeg
+        }
+    }
+
+    // Check PATH
+    path, err := exec.LookPath("ffmpeg")
+    if err == nil {
+        return path
+    }
+
+    return "ffmpeg" // fallback
+}
+```
+
+### 2. Process Management
+
+**Current**: Uses `context.WithCancel()` for process termination
+**Windows Issue**: Windows doesn't support SIGTERM signals
+
+**Solution**:
+```go
+func killFFmpegProcess(cmd *exec.Cmd) error {
+    if runtime.GOOS == "windows" {
+        // Windows: use Kill() directly
+        return cmd.Process.Kill()
+    } else {
+        // Unix: try graceful shutdown first
+        cmd.Process.Signal(os.Interrupt)
+        time.Sleep(1 * time.Second)
+        return cmd.Process.Kill()
+    }
+}
+```
+
+### 3. File Path Handling
+
+**Current**: Good use of `filepath` package
+**Potential Issues**: UNC paths, drive letters
+
+**Enhancements**:
+```go
+// Validate Windows-specific paths
+func validateWindowsPath(path string) error {
+    if runtime.GOOS != "windows" {
+        return nil
+    }
+
+    // Check for drive letter
+    if len(path) >= 2 && path[1] == ':' {
+        drive := strings.ToUpper(string(path[0]))
+        if drive < "A" || drive > "Z" {
+            return fmt.Errorf("invalid drive letter: %s", drive)
+        }
+    }
+
+    // Check for UNC path
+    if strings.HasPrefix(path, `\\`) {
+        // Valid UNC path
+        return nil
+    }
+
+    return nil
+}
+```
+
+### 4. Hardware Acceleration Detection
+
+**Current**: Linux-focused (VAAPI detection)
+**Windows Needs**: NVENC, QSV, AMF detection
+
+**Implementation**:
+```go
+func detectWindowsGPU() []string {
+    var encoders []string
+
+    // Test for NVENC (NVIDIA)
+    if testFFmpegEncoder("h264_nvenc") {
+        encoders = append(encoders, "nvenc")
+    }
+
+    // Test for QSV (Intel)
+    if testFFmpegEncoder("h264_qsv") {
+        encoders = append(encoders, "qsv")
+    }
+
+    // Test for AMF (AMD)
+    if testFFmpegEncoder("h264_amf") {
+        encoders = append(encoders, "amf")
+    }
+
+    return encoders
+}
+
+func testFFmpegEncoder(encoder string) bool {
+    cmd := exec.Command(findFFmpeg(), "-encoders")
+    output, err := cmd.Output()
+    if err != nil {
+        return false
+    }
+    return strings.Contains(string(output), encoder)
+}
+```
+
+### 5. Temporary File Cleanup
+
+**Current**: Uses `os.TempDir()`
+**Windows Enhancement**: Better cleanup on Windows
+
+```go
+func createTempVideoDir() (string, error) {
+    baseDir := os.TempDir()
+    if runtime.GOOS == "windows" {
+        // Use AppData\Local\Temp\VideoTools on Windows
+        appData := os.Getenv("LOCALAPPDATA")
+        if appData != "" {
+            baseDir = filepath.Join(appData, "Temp")
+        }
+    }
+
+    dir := filepath.Join(baseDir, fmt.Sprintf("videotools-%d", time.Now().Unix()))
+    return dir, os.MkdirAll(dir, 0755)
+}
+```
+
+### 6. File Associations and Context Menu
+
+**Windows Registry Integration** (optional for later):
+```
+HKEY_CLASSES_ROOT\*\shell\VideoTools
+    @="Open with VideoTools"
+    Icon="C:\Program Files\VideoTools\VideoTools.exe,0"
+
+HKEY_CLASSES_ROOT\*\shell\VideoTools\command
+    @="C:\Program Files\VideoTools\VideoTools.exe \"%1\""
+```

+    logging.Debug(logging.CatSystem, "Platform: %s, FFmpeg: %s", runtime.GOOS, platformConfig.FFmpegPath)
+
+    // ... rest of main

+
+Update FFmpeg command construction:
+```go
+func (s *appState) startConvert(...) {
+    // Use platform-specific ffmpeg path
+    cmd := exec.CommandContext(ctx, platformConfig.FFmpegPath, args...)
+
+    // ... rest of function
