RTSP 1.0 client and server library for the Go programming language, written for MediaMTX.
Go ≥ 1.19 is required.
Features:
- Client
- Query servers about available media streams
- 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 only
- Pause or seek without disconnecting from the server
- Get PTS (relative) timestamp of incoming packets
- Get NTP (absolute) timestamp of incoming packets
- Publish
- Publish media 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
- Server
- Handle requests from clients
- Publish
- Read media streams from clients with the UDP or TCP transport protocol

In RTSP, media streams are routed between server and clients by using RTP packets. Conversion between RTP packets and codec-specific frames happens by using a payload format. This library recognizes the following payload formats:
| format / codec | variant | documentation | encoder and decoder available |
|---|---|---|---|
| AV1 | link | ✔️ | |
| VP9 | link | ✔️ | |
| VP8 | link | ✔️ | |
| H265 | link | ✔️ | |
| H264 | link | ✔️ | |
| MPEG-4 Video (H263, Xvid) | link | ✔️ | |
| MPEG-1/2 Video | link | ||
| M-JPEG | link | ✔️ |
| format / codec | variant | documentation | encoder and decoder available |
|---|---|---|---|
| Opus | link | ✔️ | |
| Vorbis | link | ||
| MPEG-4 Audio (AAC) | Generic (RFC3640) | link | ✔️ |
| MPEG-4 Audio (AAC) | LATM (RFC6416) | link | ✔️ |
| MPEG-1/2 Audio (MP3) | link | ✔️ | |
| Speex | link | ||
