gortsplib

RTSP 1.0 client and server library for the Go programming language, written for rtsp-simple-server.

Go ≥ 1.17 is required.

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 codec-specific frames into/from RTP packets. The following codecs 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
