README

Silly Videos is a PHP library used to obtain videos starting from a JSON configuration describing simple elements like texts and images.

It generates the required frames, one by one, and collect them into a video using ffmpeg.

This project has been initially implemented to generate social contents (like: YouTube and Instagram) for TrendingOnWiki.

Install

composer require madbob/silly-videos

It is required the PHP gd extension and, of course, ffmpeg.

Usage

use MadBob\SillyVideos\SillyVideos;

// Use by JSON configuration file
SillyVideos::runFromFile($file, '/tmp/out.mp4');

// Use by in memory (eventually, dynamically generated) configuration
SillyVideos::run($config, '/tmp/out.mp4');

// Multi-process modes: forks multiple times to parallelize frames generation
SillyVideos::runFromFile($file, '/tmp/out.mp4', 4);
SillyVideos::run($config, '/tmp/out.mp4', 4);
