RTMP client and server library for the Go programming language, forked from [MediaMTX](https://github.com/bluenviron/mediamtx).

This was created to provide [Enhanced RTMP](https://veovera.org/docs/enhanced/enhanced-rtmp-v2) features, like multiple video/audio tracks and additional codecs.

Go ≥ 1.24 is required.

Features:

* Read and write multiple video and audio tracks

* Read and write tracks encoded with AV1, VP9, H265, H264, Opus, MPEG-4 Audio (AAC), MPEG-1/2 Audio (MP3), AC-3, G711 (PCMA, PCMU), LPCM

* Support most Enhanced RTMP features

* Support TLS encryption (RTMPS)

* Support Diffie-hellman based encryption (RTMPE)

Current limitations:

* API is not stable and might be subjected to breaking changes.

* Codec definitions are borrowed from gortsplib. They will be made independent in the future.
