RTSP 1.0 client and server library for the Go programming language, written for [rtsp-simple-server](https://github.com/aler9/rtsp-simple-server).
Go ≥ 1.17 is required.
***WARNING: the main branch contains code of the v2 version. The legacy v1 version is hosted in the [v1 branch](https://github.com/aler9/gortsplib/tree/v1).***
Features:
* Client
* Query servers about available streams and mediastreams
* Read
* Read media streams from servers with the UDP, UDP-multicast or TCP transport protocol
* Read TLS-encrypted streams (TCP only)
* Switch transport protocol automatically
* Read only selected media streams
* Pause or seek without disconnecting from the server
* Generate RTCP receiver reports (UDP only)
* Reorder incoming RTP packets (UDP only)
* Publish
* Publish streams to servers with the UDP or TCP transport protocol
* Publish TLS-encrypted streams (TCP only)
* Switch transport protocol automatically
* Pause without disconnecting from the server
* Generate RTCP sender reports
* Server
* Handle requests from clients
* Sessions and connections are independent
* Publish
* Read media streams from clients with the UDP or TCP transport protocol
* Read TLS-encrypted streams (TCP only)
* Generate RTCP receiver reports (UDP only)
* Reorder incoming RTP packets (UDP only)
* Read
* Write media streams to clients with the UDP, UDP-multicast or TCP transport protocol
* Write TLS-encrypted streams
* Compute and provide SSRC, RTP-Info to clients
* Generate RTCP sender reports
* Utilities
* Encode and decode format-specific frames into/from RTP packets. The following formats are supported:
* Video: H264, H265, VP8, VP9
* Audio: G711 (PCMA, PCMU), G722, LPCM, MPEG4-audio (AAC), Opus
* Parse RTSP elements: requests, responses, SDP
* Parse H264 elements and formats: Annex-B, AVCC, anti-competition, DTS
* Parse MPEG4-audio (AAC) element and formats: ADTS, MPEG4-audio configurations
