When I first heard of ReactPHP a few years ago, it looked very promising. Providing timers, asynchronous processing, streams, and sockets, all within PHP.
However, in recent years, there seems to be stagnation. While you see commits, you seldom see any publication.
Framework X is an attempt to make ReactPHP into a micro framework, but I see little mention of it.
Overall, whenever I tried using ReactPHP, I found that it is better to use Laravel and its rich ecosystem.
Building Video Streaming Server with ReactPHP was a nice approach to building a streaming server with ReactPHP, which I could not see how to do as simple in Laravel.
This got me thinking about how far you can go with ReactPHP in terms of streaming.
A media server has three components:
Streaming of media files
Web interface to select files, login users, and control playback.
A backend to manage files and users
While ReactPHP is very good for the streaming part, web application programming with ReactPHP is not common and lacks an ecosystem of build tools and libraries.
This is especially apparent if you want to build a dynamic modern interface, as you do nowadays with a Single Page Application (SPA).
So it would seem natural to wrap the ReactPHP in a Laravel application. Laravel is well suited for managing files, including file upload, and has built-in user management.
Laravel Media Library associates media, such as video files, to your models.
The library integrates FFMpeg through the PHP-FFMPEG so that you can create thumbnails of videos. Moreover, using PHP-FFMPEG, you can do all common transcoding of videos.
Standard Laravel validation rules handle video file size and type.
However, a media server needs a more targeted validation of videos, such as duration, codec, and dimensions.
Laravel Audio & Video Validator supplies these extra validations based on FFMpeg.
Possibly, we would need to fork and extend their code to support additional validations, such as frame rate and bitrate.
