- Wirehair library (auto-compiled if not found)

⚙️ Quick Setup
--------------

[](#️-quick-setup)

Run the interactive setup wizard:

```
php artisan yt:setup
```

This will:

1. ✅ Auto-detect system binaries (FFmpeg, FFprobe, yt-dlp)
2. ✅ Compile Wirehair from source if needed
3. ✅ Validate all dependencies via health check
4. ✅ Prompt for YouTube OAuth credentials
5. ✅ Write configuration to `.env`

### Manual Configuration

[](#manual-configuration)

Publish the config file:

```
php artisan vendor:publish --provider="Shamimstack\YouTubeCloudStorage\YTStorageServiceProvider" --tag="config"
```

Edit `config/youtube-storage.php`:

```
return [
    'ffmpeg_path' => '/usr/bin/ffmpeg',
    'ffprobe_path' => '/usr/bin/ffprobe',
    'ytdlp_path' => '/usr/bin/yt-dlp',

        'client_secret' => env('YOUTUBE_CLIENT_SECRET'),
        'refresh_token' => env('YOUTUBE_REFRESH_TOKEN'),
    ],

    // Advanced tuning
    'coefficient_threshold' => 10,
    'redundancy_factor' => 1.5,
    'dct_positions' => [[1, 2], [2, 1]],
];
```

Add to your `.env`:

```
FFMPEG_PATH=/usr/bin/ffmpeg
FFPROBE_PATH=/usr/bin/ffprobe
YTDLP_PATH=/usr/bin/yt-dlp
YOUTUBE_API_KEY=your_api_key
YOUTUBE_CLIENT_ID=your_client_id
YOUTUBE_CLIENT_SECRET=your_client_secret
YOUTUBE_REFRESH_TOKEN=your_refresh_token
```

🔑 Obtain YouTube Credentials
----------------------------

[](#-obtain-youtube-credentials)

1. Go to [Google Cloud Console](https://console.cloud.google.com/)
2. Create/select a project
3. Enable **YouTube Data API v3**
4. Go to **Credentials** → **Create Credentials** → **OAuth client ID**
5. Application type: **Web application**
6. Authorized redirect URIs: `http://localhost/callback`
7. Copy Client ID and Client Secret
8. Complete OAuth flow to get Refresh Token

💾 Usage
-------

[](#-usage)

### Via Storage Facade

[](#via-storage-facade)

```
use Illuminate\Support\Facades\Storage;

// Upload a file
$disk = Storage::disk('youtube');
$disk->put('backup.zip', file_get_contents('/path/to/file.zip'));

// Download a file
$data = $disk->get('backup.zip');
file_put_contents('/tmp/restored.zip', $data);

// List files
$files = $disk->allFiles();

// Delete a file
$disk->delete('backup.zip');
```

### Via Artisan Commands

[](#via-artisan-commands)

**Upload:**

```
# Basic upload
php artisan yt:store /path/to/file.pdf

# With custom redundancy (2x packets)
php artisan yt:store /path/to/file.zip --redundancy=2.0

# Specify title/metadata
php artisan yt:store /path/to/image.png \
  --title="My Image" \
  --description="Uploaded via YTStorage" \
  --privacy=private
```

**Download:**

```
# Restore from YouTube URL
php artisan yt:restore "https://youtube.com/watch?v=dQw4w9WgXcQ"

# Specify output path
php artisan yt:restore "https://..." --output=/tmp/restored.pdf

# Restore multiple files
php artisan yt:restore \
  "https://youtube.com/watch?v=abc" \
  "https://youtube.com/watch?v=def"
```

### Programmatic Access

[](#programmatic-access)

```
use Shamimstack\YouTubeCloudStorage\Engines\EncoderEngine;
use Shamimstack\YouTubeCloudStorage\Support\HealthCheck;

// Run health check
$healthCheck = app(HealthCheck::class);
$report = $healthCheck->run();

if (!$report['passed']) {
    foreach ($report['checks'] as $check) {
        if (!$check['passed']) {
            echo "Failed: {$check['name']} - {$check['message']}\n";
        }
    }
    exit(1);
}

// Encode and upload
$engine = app(EncoderEngine::class);
$result = $engine->encodeAndUpload(
    filePath: '/path/to/file.pdf',
    title: 'My Document',
    description: 'Encoded with DCT steganography',
    privacyStatus: 'private',
);

echo "Uploaded to: {$result['videoUrl']}\n";
echo "Packets: {$result['packetCount']}\n";
echo "Size: {$result['originalSizeBytes']} bytes\n";

// Download and decode
$decodedPath = $engine->downloadAndDecode(
    videoUrl: 'https://youtube.com/watch?v=...',
    outputPath: '/tmp/restored.pdf',
);

// Verify integrity
if (hash_file('sha256', '/path/to/file.pdf') === hash_file('sha256', $decodedPath)) {
    echo "✅ Data integrity verified!\n";
}
```

```

### DCT Steganography

[](#dct-steganography)

Each video frame undergoes Discrete Cosine Transform (DCT), converting spatial pixels into frequency coefficients. Data is embedded by nudging the **sign** of selected coefficients:

- **Bit 0** → Make coefficient positive
- **Bit 1** → Make coefficient negative

The magnitude is kept above a threshold (default: 10) to survive YouTube's re-encoding.

**Mathematical Foundation:**

```
Forward DCT:  F = T · B · T^T
Inverse DCT:  B = T^T · F · T

Where:
- B = 8×8 pixel block
- F = 8×8 frequency coefficients
- T = DCT basis matrix (orthonormal)

```

### Fountain Codes for Redundancy

[](#fountain-codes-for-redundancy)

Wirehair implements O(N) fountain codes, generating unlimited repair packets:

- **Systematic packets**: Original data chunks
- **Repair packets**: Linear combinations via XOR

**Recovery guarantee**: Any N + ε packets can reconstruct the original file, where ε ≈ 2%.

🛠 Troubleshooting
-----------------

[](#-troubleshooting)

### Check Dependencies

[](#check-dependencies)

```
php artisan yt:setup --no-interaction
```

### Common Issues

[](#common-issues)

**FFmpeg not found:**

```
# Install on Ubuntu/Debian
sudo apt-get install ffmpeg

# Install on macOS
brew install ffmpeg

# Install on Windows
choco install ffmpeg
```

**Wirehair compilation failed:**

```
# Install build tools
sudo apt-get install gcc cmake  # Linux
brew install cmake             # macOS
```

**YouTube upload quota exceeded:**

- YouTube API has daily upload limits
- Use private videos to avoid public quota restrictions
- Wait 24 hours for quota reset

📊 Performance Benchmarks
------------------------

[](#-performance-benchmarks)

File TypeSizeEncode TimeDecode TimeVideo DurationPacketsText1 MB~30s~25s10 sec12Image5 MB~2m 30s~2m 10s50 sec60Archive10MB~5m~4m 30s100 sec120*Benchmarks vary by CPU speed, DCT positions count, and network.*

🔒 Security Considerations
-------------------------

[](#-security-considerations)

- **Encryption**: Files are NOT encrypted by default (steganography only)
- **Privacy**: Set videos to "private" to prevent public access
- **Authentication**: OAuth tokens stored in `.env` (keep secure!)
- **Data Integrity**: CRC32 checksums verify packet authenticity

🎯 Roadmap
---------

[](#-roadmap)

- AES-256 encryption before encoding
- Batch upload (multiple files per video)
- Progress callbacks during encode/decode
- GPU acceleration for DCT operations
- Multi-threaded packet processing
- Resume interrupted uploads
- Automatic chunking for large files (>1GB)
