README

PHP Version License

A comprehensive codec implementation package for WebRTC applications, providing audio/video encoding and decoding capabilities.

About this fork

This is the danog/php-rtc-codecs fork used by MadelineProto. It targets PHP 8.2+, can packetize already-encoded media without FFI, and adds VP9 RTP payload parsing and packetization alongside the existing Opus, VP8, and H.264 support.

All internal Composer dependencies use their danog/php-rtc-* package names directly, so installing a component selects the maintained danog packages throughout the dependency graph.

  • PCM A-law (encode/decode)
