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 tracks
  • Read
    • Read 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 tracks of a stream
    • Pause or seek without disconnecting from the server
    • Generate RTCP receiver reports (UDP only)
    • Reorder incoming RTP packets (UDP only)
    • Clean up non-compliant streams (remove padding, re-encode RTP packets if they are too big)
  • 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 (UDP only)
• Server
  • Handle requests from clients
  • Sessions and connections are independent
  • Publish
    • Read 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)
    • Clean up non-compliant streams (remove padding, re-encode RTP packets if they are too big)
  • Read
    • Write 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 (UDP only)
• Utilities
  • Parse RTSP elements: requests, responses, SDP
  • Parse H264 elements and formats: RTP/H264, Annex-B, AVCC, anti-competition, DTS
  • Parse AAC elements and formats: RTP/AAC, ADTS, MPEG-4 audio configurations
