# Offline Installation Guide

## Architecture Compatibility

### Current Libraries (req_libraries/)
- Compatible with: 64-bit Raspberry Pi OS (aarch64)
- NOT compatible with: 32-bit Raspberry Pi OS (armv7l)

### For 32-bit Raspberry Pi OS

The current wheels contain aarch64 packages that won't work on 32-bit systems.

## Installation Options

### 64-bit Raspberry Pi OS:
```bash
./install_offline.sh
```

### 32-bit Raspberry Pi OS:
1. Run on internet-connected system: `./download_32bit_libs.sh`
2. Copy req_libraries_32bit/ to offline system
3. Rename: `mv req_libraries_32bit req_libraries`
4. Run: `./install_offline.sh`

## System Requirements

### 32-bit systems need build tools:
```bash
sudo apt update
sudo apt install build-essential python3-dev python3-pip
```

### All systems need VLC:
```bash
sudo apt install vlc
```

## Quick Check
```bash
uname -m
```
- aarch64 = 64-bit (current wheels work)
- armv7l = 32-bit (need different wheels)
