README

A Laravel wrapper for ab-av1, the AV1 video encoder with automatic CRF calculation and VMAF quality targeting.

Features

• Automatic CRF Discovery: Find the optimal CRF value to achieve target VMAF quality
• Multiple Encoders: Support for av1_svtenc, av1_vaapi, libx264, libx265, and other ffmpeg encoders
• Quick Sampling: Test encode quality before full encoding
• Hardware Acceleration: Support for VAAPI and other hardware acceleration methods
• VMAF/XPSNR Comparison: Calculate quality scores between original and encoded files
• Event Dispatching: Listen to encoding events (started, completed, failed)
• Fluent Interface: Chainable configuration API

Installation

Ensure ab-av1 is installed:

# macOS
brew install ab-av1

# Linux (Arch)
sudo pacman -S ab-av1

Install the Laravel package:

composer require foxws/laravel-ab-av1

Publish the config:

php artisan vendor:publish --provider="Foxws\AbAv1\AbAv1ServiceProvider"

Configuration

Binary Path

By default, the package expects ab-av1 to be in your system PATH. If you need to use a specific binary path or version, configure it in config/ab-av1.php or via environment variable:

# .env
AB_AV1_BINARY=/usr/local/bin/ab-av1
# Or use a specific cargo installation
AB_AV1_BINARY=/home/user/.cargo/bin/ab-av1

Verify your installation:

php artisan ab-av1:info

Quick Start

use Foxws\AbAv1\Facades\AbAv1;

$result = AbAv1::encode()
    ->withInput('/path/to/video.mp4')
    ->withPreset('medium')
    ->withMinVMAF(95)
    ->autoEncode();

echo "VMAF: {$result->getVMAFScore()}";
echo "CRF: {$result->getCRFUsed()}";

Usage Examples

Auto-encode (Recommended)

Automatically find the best CRF for your target VMAF quality:

$result = AbAv1::encode()
    ->withInput('video.mp4')
    ->withPreset('medium')
    ->withMinVMAF(95)
    ->withOutput('output.mp4')
    ->autoEncode();

Direct Encode

Encode with a specific CRF value:

$result = AbAv1::encode()
    ->withInput('video.mp4')
    ->withCRF(30)
    ->withPreset('slow')
    ->encode();

Sample Encode

Quick test to preview quality:

$result = AbAv1::encode()
    ->withInput('video.mp4')
    ->withCRF(28)
    ->sampleEncode();

Hardware Acceleration

Enable VAAPI for faster encoding:

$result = AbAv1::encode()
    ->withInput('video.mp4')
    ->withPreset('medium')
    ->withMinVMAF(95)
    ->withFFmpegOptions([
        'hwaccel' => 'vaapi',
        'hwaccel_output_format' => 'vaapi',
    ])
    ->autoEncode();

Testing
