gortsplib
RTSP 1.0 client and server library for the Go programming language, written for MediaMTX.
Go ≥ 1.21 is required.
Features:
- Client
- Query servers about available media streams
- Play (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 selected media streams
- Pause or seek without disconnecting from the server
- Write to ONVIF back channels
- Get PTS (relative) timestamp of incoming packets
- Get NTP (absolute) timestamp of incoming packets
- Record (write)
- Write media streams to servers with the UDP or TCP transport protocol
- Write TLS-encrypted streams (TCP only)
- Switch transport protocol automatically
- Pause without disconnecting from the server
- Server
- Handle requests from clients
- Record (read)
- Read media streams from clients with the UDP or TCP transport protocol
- Read TLS-encrypted streams (TCP only)
- Get PTS (relative) timestamp of incoming packets
- Get NTP (absolute) timestamp of incoming packets
- Play (write)
- Write media streams to clients with the UDP, UDP-multicast or TCP transport protocol
- Write TLS-encrypted streams (TCP only)
- Compute and provide SSRC, RTP-Info to clients
- Utilities
- Parse RTSP elements
- Encode/decode RTP packets into/from codec-specific frames

RTP Payload Formats
In RTSP, media streams are transmitted by using RTP packets, which are encoded in a specific, codec-dependent, format. This library supports formats for the following codecs:
