// Initialize converter
$converter = new YouTubeConverter(

        }
    }
} catch (ConverterException $e) {
    echo "Error: " . $e->getMessage();
}

use Darkwob\YoutubeMp3Converter\Converter\Options\ConverterOptions;

$options = new ConverterOptions();
$options
    ->setAudioFormat('mp3')                    // mp3, wav, aac, m4a, opus, vorbis, flac
    ->setAudioQuality(0)                       // 0 (best) to 9 (worst)
    ->setVideoFormat('bestaudio/best')         // Video format selection
    ->enableSponsorBlock()                     // Skip sponsored segments
    ->setPlaylistItems('1-10')                 // Process specific items
    ->setDateFilter('20220101', '20231231')    // Date range filter
    ->setFileSizeLimit('100M')                 // Maximum file size
    ->setOutputTemplate('%(title)s.%(ext)s')   // Custom output template
    ->setProxy('socks5://127.0.0.1:1080')      // Proxy configuration
    ->setRateLimit(3)                          // Downloads per minute
    ->enableThumbnail()                        // Embed thumbnail
    ->setMetadata([                            // Custom metadata
        'artist' => '%(uploader)s',
        'title' => '%(title)s'
    ]);

$converter = new YouTubeConverter($binPath, $outputDir, $tempDir, $progress, $options);

Remote Conversion

use Darkwob\YoutubeMp3Converter\Converter\Remote\RemoteConverter;

$remote = new RemoteConverter(
    'https://api.converter.com',
    'your-api-token'
);

// Async conversion
$jobId = $remote->startConversion($url, $options);

// Check progress
$status = $remote->getProgress($jobId);

// Download when ready
if ($status['status'] === 'completed') {
    $remote->downloadFile($jobId, 'output.mp3');
}

Progress Tracking with Redis

use Darkwob\YoutubeMp3Converter\Progress\RedisProgress;

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$progress = new RedisProgress($redis, 'converter:', 3600);

// Track progress
$progress->update('video123', 'downloading', 50, 'Downloading video...');

// Get progress
$status = $progress->get('video123');
echo "Progress: {$status['progress']}%\n";
