Are there ready-made free video chat solutions in js + php?

Question

PHP

Ratchet + PHP7 + Phalcon is running on the server, Bootstrap is on the front.
It is necessary to embed a video chat system into the existing solution, and I really would not want to cut it from scratch. Are there any off-the-shelf open source solutions or partial solutions? There is Magnoliyan Video Chat which fits perfectly, but the pricing policy of this product does not suit the authorities.
Are there analogues?

Answer 1

In general, having written the project, I can say that of the free solutions there is only
https://www.webrtc-experiment.com/ , which, due to the freshness of WebRTC itself, becomes obsolete a month after writing, and the author reacts very lazily to this fact .
The only decent (non-commercial) option is to write in pure WebRTC, carefully approaching deprecated methods and carefully burning them out of code examples. At least for the current moment.
This article is outdated, something more or less fresh from the documentation is only on this site

Answer 2

PPVCHAT yes
