What the Installer Does

The install.sh script performs these steps:

Step 1: Go Verification

• Checks if Go 1.21+ is installed
• Displays Go version
• Exits with helpful error message if not found

Step 2: Build

• Cleans previous builds
• Downloads dependencies
• Compiles VideoTools binary
• Validates build success

Step 3: Installation Path Selection

• Presents two options:
  • System-wide (/usr/local/bin)
  • User-local (~/.local/bin)
• Creates directories if needed

Step 4: Binary Installation

• Copies binary to selected location
• Sets proper file permissions (755)
• Validates installation

Step 5: Shell Environment Setup

• Detects your shell (bash/zsh)
• Adds VideoTools installation path to PATH
• Sources alias script for convenience commands
• Adds to appropriate rc file (.bashrc or .zshrc)

---

Convenience Commands

After installation, you'll have access to:

VideoTools              # Run VideoTools directly
VideoToolsRebuild       # Force rebuild from source
VideoToolsClean         # Clean build artifacts and cache

---

Requirements

Essential

• Go 1.21 or later - https://go.dev/dl/
• Bash or Zsh shell

Optional

• FFmpeg (for actual video encoding)

  ffmpeg -version
  

System

• Linux, macOS, or WSL (Windows Subsystem for Linux)
• At least 2 GB free disk space
• Stable internet connection (for dependencies)

Troubleshooting

"Go is not installed"

Solution: Install Go from https://go.dev/dl/

# After installing Go, verify:
go version

Build Failed

Solution: Check build log for specific errors:

bash install.sh
# Look for error messages in the build log output

Installation Path Not in PATH

If you see this warning:

Warning: ~/.local/bin is not in your PATH

Solution: Reload your shell:

source ~/.bashrc    # For bash
source ~/.zshrc     # For zsh

Or manually add to your shell configuration:

# Add this line to ~/.bashrc or ~/.zshrc:
export PATH="$HOME/.local/bin:$PATH"

"Permission denied" on binary

Solution: Ensure file has correct permissions:

chmod +x ~/.local/bin/VideoTools
# or for system-wide:
ls -l /usr/local/bin/VideoTools

Aliases Not Working

Solution: Ensure alias script is sourced:

# Check if this line is in your ~/.bashrc or ~/.zshrc:
source /path/to/VideoTools/scripts/alias.sh

# If not, add it manually:
echo 'source /path/to/VideoTools/scripts/alias.sh' >> ~/.bashrc
source ~/.bashrc

---

Advanced: Manual Installation

If you prefer to install manually:

Step 1: Build

cd /path/to/VideoTools
CGO_ENABLED=1 go build -o VideoTools .

Step 2: Install Binary

# User-local installation:
mkdir -p ~/.local/bin
cp VideoTools ~/.local/bin/VideoTools
chmod +x ~/.local/bin/VideoTools

# System-wide installation:
sudo cp VideoTools /usr/local/bin/VideoTools
sudo chmod +x /usr/local/bin/VideoTools

Step 3: Setup Aliases

# Add to ~/.bashrc or ~/.zshrc:
source /path/to/VideoTools/scripts/alias.sh

# Add to PATH if needed:
export PATH="$HOME/.local/bin:$PATH"

Step 4: Reload Shell

source ~/.bashrc    # for bash
source ~/.zshrc     # for zsh

---

Uninstallation

If Installed System-Wide

sudo rm /usr/local/bin/VideoTools

If Installed User-Local

rm ~/.local/bin/VideoTools

Remove Shell Configuration

Remove these lines from ~/.bashrc or ~/.zshrc:

# VideoTools installation path
export PATH="$HOME/.local/bin:$PATH"

# VideoTools convenience aliases
source "/path/to/VideoTools/scripts/alias.sh"

---

Verification

After installation, verify everything works:

# Check binary is accessible:
which VideoTools

# Check version/help:
VideoTools --help

# Check aliases are available:
type VideoToolsRebuild
type VideoToolsClean
