README

A simple PHP-based video encoder that converts raw RGB24 frames to YUV420p format using custom pixel processing.

Features

• Convert RGB24 frames to YUV420p format
• Efficient pixel processing
• Simple and easy-to-use interface
• No external dependencies required

Requirements

• PHP >= 8.0

Installation

You can install the package via composer:

composer require devejesus/video-encoder

Usage

use Devejesus\VideoEncoder\Encoder\RGB24ToYUV420Encoder;
use Devejesus\VideoEncoder\Model\VideoConfig;

// Create a video configuration
$config = new VideoConfig(384, 216); // width and height must be even numbers

// Initialize the encoder
$encoder = new RGB24ToYUV420Encoder();

// Convert the video
try {
    $encoder->encode(
        'input.rgb24',  // Input file path (RGB24 format)
        'output.yuv',   // Output file path (YUV420p format)
        $config
    );
    echo "Conversion completed successfully!\n";
} catch (\Exception $e) {
    echo "Error: " . $e->getMessage() . "\n";
}

Input Format Requirements

• The input file must be in RGB24 format
• Width and height must be even numbers
• Each pixel is represented by 3 bytes (R, G, B)
• No headers or metadata in the file

Testing
