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:

   # 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:

   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:

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:

   git clone https://github.com/yourusername/VideoTools.git
   cd VideoTools
   

4. Build:

   set CGO_ENABLED=1
   go build -ldflags="-H windowsgui" -o VideoTools.exe
   

5. Run:

   VideoTools.exe

Cross-Compiling from Linux

If you're building for Windows from Linux:

1. Install MinGW:

   # Fedora/RHEL
   sudo dnf install mingw64-gcc mingw64-winpthreads-static
   
   # Ubuntu/Debian
   sudo apt-get install gcc-mingw-w64
   

2. Build:

   ./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
